Abstract European states currently lack a clear joint strategy on China and a coordinated approach to US–China competition. This article offers a novel perspective on the challenges for European approaches to this issue due to an omnipresent transatlantic component and the risk of an alliance dilemma. Illustratively focusing on France, Germany and the UK, it demonstrates that Europeans are facing a transatlantic alliance dilemma with the risks of abandonment and entrapment. It argues that Europe needs to strike a balance between its dependence on Washington, especially with regard to European security, while fearing entrapment by the US approach towards Beijing as it aims to maintain economic ties with China. The article concludes that the ramifications of this dilemma can be mitigated through a distinctly European approach to China, strengthening European coordination on China and bolstering European strategic autonomy. As a conceptual piece rather than a full empirical analysis, this article therefore unpacks the strategic challenge and lays the groundwork for further empirical works on the topic. Introduction Strategic competition between the US and China plays out in many realms of international affairs, ranging from global trade to security in the Indo-Pacific. European states are directly affected by this dynamic as they maintain critical ties with both sides. Albeit allies of the US through NATO, Europeans have been reluctant to align with the US on its approach to the Indo-Pacific and China, which is currently characterised by the quest to win the strategic competition with Beijing in all areas of international affairs (see Leoni 2023). Furthermore, Europe maintains close economic ties with Beijing, and imports from China to the EU have most recently increased (Lovely and Yan 2024). European governments certainly do not pursue an approach of maintaining equidistance between the US and China: not only do they regularly emphasise their strategic proximity to Washington, but more recent events, such as the willingness of European allies to publicly adopt the wording of the communiqué from NATO’s Washington summit (NATO 2024) describing China as an ‘enabler of Russia’s war effort in Ukraine’, clearly demonstrate that the tone is changing in European capitals (Politi 2023). However, Europeans still tend to emphasise China’s role in global affairs and the importance of including it in multilateral cooperation formats. With the re-election of Donald Trump as US president, European policy on China and its approach to US–China competition will increasingly be a focus of the US administration. While the exact approach of the new US government still remains to be defined, there are good reasons to anticipate a more hawkish China policy from Washington, through which the US might seek not only to further compete with China, but to actually win this competition (see Pottinger and Gallagher 2023). When designing their approaches towards China—which, among the key European states, only Germany has done so far, with the publication of its China strategy in 2023—Europeans always face a transatlantic elephant in the room. US–China competition, a structuring feature of international relations shaping the global order today through the increasing emergence of geopolitical blocs (see Leoni and Tzinieris 2024), and China’s rising global influence in almost all areas of international affairs—ranging from climate to economics, the rules-based order and security—are forcing European states to reflect on their approach vis-à-vis Beijing (for a full discussion, see Oertel 2023; García-Herrero and Vasselier 2024). As NATO members, European states also need to adapt their strategy in light of the partnership with the US as their key ally. This article argues that European approaches towards China, as shown in the examples of France, Germany and the UK, have a distinctly transatlantic component. It illustrates how these three European states find themselves in an alliance dilemma with the US, and how the risks associated with alliances also define European approaches to China and US–China competition more broadly. As the US administration regularly refers to China as a ‘challenge’ (US Department of Defense 2022), this article alludes to this formulation through the coining of the term ‘transatlantic China challenge’ to describe the strategic challenges Europeans are facing with regard to defining their approach vis-à-vis China and US–China competition more broadly. It offers a conceptual understanding of the strategic challenges for Europe in this context and thereby constitutes a basis for a more thorough empirical analysis. The alliance dilemma and European strategy in US–China competition Originating in realist international relations theory, the alliance dilemma generally describes a situation in which states face risks resulting from joining an alliance. As demonstrated by Snyder (1984), smaller allies especially face a parallel risk of abandonment and entrapment by a hegemon, that is, the dominating power, after joining an alliance. Abandonment, in these circumstances, implies that the hegemon has no further interest in defending or supporting the smaller allies, whereas entrapment refers to a situation in which a state is ‘dragged into a conflict over an ally’s interests that [it] does not share, or shares only partially’ (see Snyder 1984, 466–8). In the context of alliances, a small state is ‘the weaker part in an asymmetric relationship, which is unable to change the nature or functioning of the relationship on its own’ (Wivel et al. 2014, 9), and hence has more limited space for action than the great powers (Wivel and Thorhallsson 2018, 267). This definition arguably applies to Europe in its partnership with the US, as demonstrated by the excessive military and economic dominance of the US as compared to the European states (see Stockholm International Peace Research Institute n.d.; International Monetary Fund 2025). The re-election of Trump as US president now presents the risk of an increased alliance dilemma for Europeans. On the one hand, Trump has announced several times that he does not value the alliance commitments within NATO and potentially would not defend European allies (Sullivan 2024), threatening Europe with abandonment. This scenario is being taken seriously in European capitals, and reflections on how ‘defending Europe with less America’ (Grand 2024) could shape up have gained traction, especially in 2024. Similarly, defence initiatives within the EU to enhance the European contribution to the continent’s security have leapt forward in recent years (see Scazzieri 2025). On the other hand, even the Biden administration had pushed Europe to align with the US approach on China (see Lynch et al. 2023). However, France and Germany in particular, as the big EU member states, have been hesitant to do so, as reflected in France’s opposition to the opening of a NATO liaison office in Tokyo (McCurry 2023) and Germany’s vote against tariffs on Chinese electric vehicles, fearing reprisals from Beijing (Demarais 2024). Trump’s foreign policy might be strongly characterised by issue linkage, which means that policies in one area will be linked to those in another area. Through this strategy, the new US administration might force Europeans into alignment and thereby entrap them, making them accept policies they are not eager to support (see Barkin and Kratz 2025). The exact policies of the Trump administration vis-à-vis European allies remain to be seen, but it is not hard to imagine a scenario in which abandonment and entrapment could emerge or increase, namely when the threat of abandonment is used to entrap allies and force them to support certain policy decisions. The alliance dilemma could play out for Europeans specifically when designing their approaches towards China (see Barkin and Kratz 2025) and formulating their response to US–China competition more generally. As noted above, among the big European states, only Germany has formally adopted a strategy on China, in 2023 (The Federal Government of Germany 2023). However, China and the response to US–China competition takes a prominent place in France’s Indo-Pacific Strategy and its strategy review (Government of France 2021; Secrétariat général de la défense et de la sécurité nationale 2022), and the UK systematically included the dimension of strategic competition in its Integrated Review and its refresh (Government of the United Kingdom 2021, 2023) and has announced an ‘audit’ of its China policy under the new government (Taylor 2024). While these strategies emphasise their individual approaches towards China and the risks stemming from US–China competition, the US has increasingly pressured Europe to align with its approach (Lynch et al. 2023) and can be expected to continue this pressure (Barkin and Kratz 2025). Through the potential issue linkage of security (openly questioned by President Trump) and China policy, Europe therefore finds itself in a new form of alliance security dilemma. European approaches to US–China competition: strategic hedging How can Europe respond to the alliance dilemma of the risks of abandonment and entrapment when it comes to its approaches to China? Reviewing the theoretical literature on the alliance dilemma, one can imagine different strategies. According to Snyder, members of alliances can choose between strategies that strengthen or weaken their commitment to the alliance. To demonstrate commitment, actions could include reassurances for the ally or demonstrations of loyalty, whereas actions to weaken the commitment to the alliance could consist of restraining the ally (mostly to reduce the risk of entrapment in a conflict), increasing bargaining power over the ally or preserving options for realignment outside the existing alliance (for a full discussion, see Snyder 1984, 466–9). Alternative strategies include hiding from cooperation, that is, ‘seeking to maximize autonomy by opting out of specific aspects of the cooperation or by setting up “bastions” in the cooperation’, or bandwagoning, through which states pursue strategies of adaptation ‘to the more powerful actors in the cooperation’ (Pedersen 2023, 442). At the moment, it seems that France, Germany and the UK ‘drive on sight’ rather than approaching the question holistically. The following analysis aims to unpack how the three European states see US–China competition, the risk of the alliance dilemma and how these reflections have played out so far in their strategies. The strategies of France, Germany and the UK on China demonstrate that their approaches are influenced by a distinctly transatlantic component and reflect the transatlantic alliance dilemma. This is visible in their (1) high awareness of the risks stemming from great power competition, (2) approaches to managing the risk of short-term abandonment, and (3) hedging to mitigate the medium- and long-term risks of abandonment and entrapment. The empirical evidence for this analysis was gathered through a qualitative analysis of European strategic documents, statements and policy decisions taken mostly during the period of the Biden administration. However, in light of the risk of a scaling-up of the alliance dilemma under the Trump administration, sources and evidence accessible by the end of January 2025 were included to illustrate the European approaches. In addition to publicly available documents and the sources mentioned above, this paper draws on conversations with policymakers and experts under the Chatham House rule. Mitigating risks from US–China competition: multilateralism instead of alignment That France, Germany and the UK are close allies with the US is clearly visible in their respective strategies on China, not least because of references they make to the importance of the alliance and their descriptions of their own positions between the two great powers. Overall, France, Germany and the UK share the perception of US–China competition and the emergence of blocs as potentially harmful to their interests. As a consequence, all three call for an inclusive multilateral order instead of falling into a logic of blocs, as the increasing competition is seen as a risk for Europe (Secrétariat général de la défense et de la sécurité nationale 2022, 9–15; The Federal Government of Germany 2020, 24–6; Government of the United Kingdom 2023, 22–6). The response of all three European powers to the emergence of blocs is multilateralism: instead of clearly aligning with the US, the French, German and British strategies call for building broader multilateral coalitions, which should, eventually, also include China (The Federal Government of Germany 2020, 23–6; Government of the United Kingdom 2023). The tone in Paris, Berlin and London towards Beijing has clearly changed over recent years; accordingly, the European capitals were also willing to support strong wording on China in the 2024 NATO summit declaration, which describes China as a ‘critical enabler’ of Russia’s ongoing war against Ukraine (NATO 2024). Albeit also recognised as a critical partner for key issues such as climate policy and trade, European states openly describe China as a ‘systemic rival’ and occasionally call out China’s behaviour, as they did, for example, in the case of a note verbale on the South China Sea (UN 2020). Nevertheless, Europe has not (yet) given in to US pressure to align with Washington’s more confrontational approach towards China (Etienne 2024). Even if European states and Washington have moved closer to each other, especially on economic security (Meyers and Reinsch 2023), the European positions on US–China competition demonstrate that Europeans are not willing to fully endorse or follow Washington’s approach—not least because European imports from China have increased in recent years (Lovely and Yan 2024). Managing the risk of short-term abandonment Since Trump’s election, the risk of abandonment by the US has been seen as increasingly high in Paris, Berlin and London.1 This is not least because Trump has openly questioned his willingness to adhere to Article 5 of the North Atlantic Treaty in the case of an armed attack on Europeans (Sullivan 2024). Europeans are especially concerned about issue linkage in this context, meaning that demands in a policy area other than security could be used as a condition. Concretely, Trump could use the threat of abandonment as leverage to compel Europe to align with the US on China policy.2 Barkin and Kratz (2025) suggest that Europe adopt a ‘carrot and stick’ approach, whereby Europe could start with an offer to the US: buying more liquified natural gas, defence goods and agricultural products from the US could mitigate the risk of abandonment. However, there is awareness among European states that coercion from the US to align on US–China policy, especially when linked to the threat of abandonment, might best be mitigated through enhancing European military capabilities—which would still leave the continent exposed to these threats, though to a lesser extent.3 Addressing the risk of medium- and long-term abandonment and entrapment: transatlantic hedging However, the risk of at least partial abandonment is not a new challenge for European strategy, and had already infused earlier strategic thinking. The shift of US strategic priorities away from Europe and to the Indo-Pacific has already been demonstrated in the allocation of resources to the different theatres. Moreover, European states have increasingly become aware that US forces will be withdrawn from their territories in the future and have concluded that they will have to step up their own commitment to European security (see Grand 2024). In parallel, there is an awareness in European capitals that showing more interest in the Indo-Pacific and giving more importance to policy on China is also a way for Europeans to demonstrate an understanding of their ally’s strategic priorities.4 Accordingly, the approaches of France, Germany and the UK to China and the Indo-Pacific also have to be understood as a commitment to the priorities of the US in order to keep this ally engaged in the European theatre and mitigate the risk of abandonment; however, European states abstain from fully aligning with the US approach, as their capabilities and strategic goals are perceived as diverging from those of the US. In this way, Europe aims to avoid entrapment over the medium term through slightly distancing itself from US policy. While all three European states also call for de-risking from China and diversification of their supply chains, maintaining strong economic ties with Beijing is a key component of their respective approaches—which contrasts with the US calls for decoupling. Furthermore, these states have never formally endorsed the US policy on China (Etienne 2024). Nevertheless, enhancing European capabilities would not only send a signal to Washington, but also qualify as hedging, understood as an ‘insurance policy’ to avoid a deterioration in US–Europe relations if the US opted for abandonment, or even as part of a move towards emancipation to reduce strategic dependencies on Washington (see Fiott 2018, 4–6). Conclusion: a transatlantic China challenge Designing their approaches to China and to US–China competition more broadly constitutes a complex strategic dilemma for European states. Paris, Berlin and London do not fully align with Washington’s approach, and it remains to be seen whether they will be willing to do so under the second Trump administration. To manage the risk of abandonment and entrapment, European states pursue different individual approaches to strategic hedging: their strategies on China and US–China competition are designed in a way that allows them to mitigate the risk of abandonment which might stem from significant transatlantic divergence, and to avoid automatic entrapment through their slight distancing from the US approach. From a theoretical perspective, this article has demonstrated that the alliance dilemma, along with the parallel fear of abandonment and entrapment by the US, is a major factor accounting for Europe’s limited strategies on China and its hedging behaviour. This article offers a conceptual analysis of the structural forces explaining European strategies, but other strategic cultures and relationships with the US could offer important complementary insights. To further analyse how individual European states design their strategies vis-à-vis China in light of the alliance dilemma and potential domestic constraints and specificities, neoclassical realism could offer an interesting analytical concept. This approach posits that structural forces set the parameters for foreign policy and treats domestic factors, including strategic culture, as intervening variables (see Rose 1998). Accordingly, it appears well suited for foreign policy analysis, and has indeed gained popularity in the field in recent years (see, for example, Martill and Sus 2024; Meibauer et al. 2021; Weber 2024). Empirically, this article constitutes a conceptual starting point rather than an exhaustive analysis of the strategy-making processes of European states with regard to China and US–China competition and makes a more comprehensive assessment desirable. The findings of this article have broader implications for policymaking. First, they demonstrate the necessity for Europe to determine its place in the increasing US–China competition. European coordination on the respective approaches vis-à-vis the US—especially in light of potential coercion to align—and China is of paramount importance to ensure that foreign policy strategies are mutually reinforcing and not undermining European objectives. Second, the article demonstrates that Europe currently responds to the ‘transatlantic China challenge’ through transatlantic hedging: while this strategy seems to be promising in the short term, it is questionable to what extent the strategy is sustainable and could help European states to navigate the parallel challenges of abandonment and entrapment. Unless Europe decides to fully align with the US—and it is questionable whether this decision would be in its interest—European states would be well advised to develop a sustainable long-term approach to China. A transatlantic dialogue on China, in which Europe and the US openly discuss synergies and divergences, could help prevent misunderstandings and decrease the risk of coercion or issue linkage due to a misreading of European approaches in Washington. Third, as the risks of (at least partial) abandonment and entrapment are systemic challenges due to the current composition of the transatlantic alliance, a logical step for European states to decrease their dependence on the US as the hegemon in the alliance would be to significantly strengthen European capabilities. Stronger military capabilities could help mitigate the ramifications of abandonment, and the aforementioned distinctly European strategy could allow Europe to avoid strategic entrapment in relation to China imposed by Washington. As Europe remains the junior partner in the transatlantic alliance, the parallel risks of abandonment and entrapment, as well as issue linkage, are highly likely to influence its approaches towards China in the long term, but there are certainly ways to render this ‘transatlantic China challenge’ less challenging. ORCID iDGesine Weber https://orcid.org/0009-0008-2643-0400Footnotes1.

Abstract We examine the roles of Gold and Bitcoin as a hedge, a safe haven, and a diversifier against the coronavirus disease 2019 (COVID-19) pandemic and the Ukraine War. Using a rolling window estimation of the dynamic conditional correlation (DCC)-based regression, we present a novel approach to examine the time-varying safe haven, hedge, and diversifier properties of Gold and Bitcoin for equities portfolios. This article uses daily returns of Gold, Bitcoin, S&P500, CAC 40, and NSE 50 from January 3, 2018, to October 15, 2022. Our results show that Gold is a better safe haven than the two, while Bitcoin exhibits weak properties as safe haven. Bitcoin can, however, be used as a diversifier and hedge. This study offers policy suggestions to investors to diversify their holdings during uncertain times. Introduction Financial markets and the diversity of financial products have risen in both volume and value, creating financial risk and establishing the demand for a safe haven for investors. The global financial markets have faced several blows in recent years. From the Global Financial Crisis (GFC) to the outbreak of the pandemic and uncertainty regarding economic policy measures of governments and central banks, the financial markets including equity markets around the world were faced with severe meltdowns. This similar behavior was observed in other markets including equity and commodity markets, resulting in overall uncertainty. In this scenario, the investors normally flock toward the safe-haven assets to protect their investment. In normal situations, investors seek to diversify or hedge their assets to protect their portfolios. However, the financial markets are negatively impacted when there are global uncertainties. Diversification and hedging methods fail to safeguard investors’ portfolios during instability because almost all sectors and assets are negatively affected (Hasan et al., 2021). As a result, investors typically look for safe-haven investments to safeguard their portfolios under extreme conditions (Ceylan, 2022). Baur and Lucey (2010) provide the following definitions of hedge, diversifier, and safe haven: Hedge: An asset that, on average, has no correlation or a negative correlation with another asset or portfolio. On average, a strict hedge has a (strictly) negative correlation with another asset or portfolio.Diversifier: An asset that, on average, has a positive correlation (but not perfect correlation) with another asset or portfolio. Safe haven: This is the asset that in times of market stress or volatility becomes uncorrelated or negatively associated with other assets or a portfolio. As was previously indicated, the significant market turbulence caused by a sharp decline in consumer spending, coupled with insufficient hedging opportunities, was a common feature of all markets during these times (Yousaf et al., 2022). Nakamoto (2008) suggested a remedy by introducing Bitcoin, a “digital currency,” as an alternative to traditional fiduciary currencies (Paule-Vianez et al., 2020). Bitcoin often described as “Digital Gold” has shown greater resilience during periods of crises and has highlighted the potential safe haven and hedging property against uncertainties (Mokni, 2021). According to Dyhrberg (2016), the GFC has eased the emergence of Bitcoin thereby strengthening its popularity. Bouri et al. (2017) in their study indicate that Bitcoin has been viewed as a shelter from global uncertainties caused by conventional banking and economic systems. Recent research has found that Bitcoin is a weak safe haven, particularly in periods of market uncertainty like the coronavirus disease 2019 (COVID-19) crisis (Conlon & McGee, 2020; Nagy & Benedek, 2021; Shahzad et al., 2019; Syuhada et al., 2022). In contrast to these findings, a study by Yan et al. (2022) indicates that it can function as a strong safe haven in favorable economic times and with low-risk aversion. Ustaoglu (2022) also supports the strong safe-haven characteristic of Bitcoin against most emerging stock market indices during the COVID-19 period. Umar et al. (2023) assert that Bitcoin and Gold are not reliable safe-havens. Singh et al. (2024) in their study reveal that Bitcoin is an effective hedge for investments in Nifty-50, Sensex, GBP–INR, and JPY–INR, at the same time a good diversifier for Gold. The study suggests that investors can incorporate Bitcoin in their portfolios as a good hedge against market volatility in equities and commodities markets. During the COVID-19 epidemic, Barbu et al. (2022) investigated if Ethereum and Bitcoin could serve as a short-term safe haven or diversifier against stock indices and bonds. The outcomes are consistent with the research conducted by Snene Manzli et al. (2024). Both act as hybrid roles for stock market returns, diversifiers for sustainable stock market indices, and safe havens for bond markets. Notably, Bhuiyan et al. (2023) found that Bitcoin provides relatively better diversification opportunities than Gold during times of crisis. To reduce risks, Bitcoin has demonstrated a strong potential to operate as a buffer against global uncertainty and may be a useful hedging tool in addition to Gold and similar assets (Baur & Lucey, 2010; Bouri et al., 2017; Capie et al., 2005; Dyhrberg, 2015). According to Huang et al. (2021), its independence from monetary policies and minimal association with conventional financial assets allow it to have a safe-haven quality. Bitcoins have a substantial speed advantage over other assets since they are traded at high and constant frequencies with no days when trading is closed (Selmi et al., 2018). Additionally, it has been demonstrated that the average monthly volatility of Bitcoin is higher than that of Gold or a group of international currencies expressed in US dollars; nevertheless, the lowest monthly volatility of Bitcoin is lower than the maximum monthly volatility of Gold and other foreign currencies (Dwyer, 2015). Leverage effects are also evident in Bitcoin returns, which show lower volatilities in high return periods and higher volatilities in low return times (Bouri et al., 2017; Liu et al., 2017). According to recent research, Bitcoins can be used to hedge S&P 500 stocks, which increases the likelihood that institutional and retail investors will build secure portfolios (Okorie, 2020). Bitcoin demonstrates strong hedging capabilities and can complement Gold in minimizing specific market risks (Baur & Lucey, 2010). Its high-frequency and continuous trading further enrich the range of available hedging tools (Dyhrberg, 2016). Moreover, Bitcoin spot and futures markets exhibit similarities to traditional financial markets. In the post-COVID-19 period, Zhang et al. (2021) found that Bitcoin futures outperform Gold futures.Gold, silver, palladium, and platinum were among the most common precious metals utilized as safe-haven investments. Gold is one such asset that is used extensively (Salisu et al., 2021). Their study tested the safe-haven property of Gold against the downside risk of portfolios during the pandemic. Empirical results have also shown that Gold functions as a safe haven for only 15 trading days, meaning that holding Gold for longer than this period would result in losses to investors. This explains why investors buy Gold on days of negative returns and sell it when market prospects turn positive and volatility decreases (Baur & Lucey, 2010). In their study, Kumar et al. (2023) tried to analyse the trends in volume throughout futures contracts and investigate the connection between open interest, volume, and price for bullion and base metal futures in India. Liu et al. (2016) in their study found that there is no negative association between Gold and the US stock market during times of extremely low or high volatility. Because of this, it is not a strong safe haven for the US stock market (Hood & Malik, 2013). Post-COVID-19, studies have provided mixed evidence on the safe-haven properties of Gold (Bouri et al., 2020; Cheema et al., 2022; Ji et al., 2020). According to Kumar and Padakandla (2022), Gold continuously demonstrates safe-haven qualities for all markets, except the NSE, both in the short and long term. During the COVID-19 episode, Gold’s effectiveness as a hedge and safe-haven instrument has been impacted (Akhtaruzzaman et al., 2021). Al-Nassar (2024) conducted a study on the hedge effectiveness of Gold and found that it is a strong hedge in the long run. Bhattacharjee et al. (2023) in their paper examined the symmetrical and asymmetrical linkage between Gold price levels and the Indian stock market returns by employing linear autoregressive distributed lag and nonlinear autoregressive distributed lag models. The results exhibit that the Indian stock market returns and Gold prices are cointegrated. According to the most recent study by Kaczmarek et al. (2022), Gold has no potential as a safe haven, despite some studies on the COVID-19 pandemic showing contradictory results. The co-movements of Bitcoin and the Chinese stock market have also normalized as a result of this epidemic (Belhassine & Karamti, 2021). Widjaja and Havidz (2023) verified that Gold was a safe haven asset during the COVID-19 pandemic, confirming the Gold’s safe-haven characteristic. As previously pointed out, investors value safe-haven investments in times of risk. Investors panic at these times when asset prices fall and move from less liquid (risky) securities to more liquid (safe) ones, such as cash, Gold, and government bonds. An asset must be bought and sold rapidly, at a known price, and for a reasonably modest cost to be considered truly safe (Smales, 2019). Therefore, we need to properly re-examine the safe-haven qualities of Gold and Bitcoin due to the mixed evidences regarding their safe-haven qualities and the impact of COVID-19 and the war in Ukraine on financial markets. This work contributes to and deviates from the body of existing literature in the following ways. We propose a novel approach in this work to evaluate an asset’s time-varying safe haven, hedge, and diversifier characteristics. This research examines the safe haven, hedging, and diversifying qualities of Gold and Bitcoin against the equity indices; S&P 500, CAC 40, and NSE 50. Through the use of rolling window estimation, we extend the methodology of Ratner and Chiu (2013) by estimating the aforementioned properties of the assets. Comparing rolling window estimation to other conventional techniques, the former will provide a more accurate representation of an asset’s time-varying feature. This study explores the conventional asset Gold’s time-varying safe haven, hedging, and diversifying qualities during crises like the COVID-19 pandemic and the conflict in Ukraine. We use Bitcoin, an unconventional safe-haven asset, for comparison. Data and Methodology We use the daily returns of three major equity indices; S&P500, CAC 40, and NSE 50 from January 3, 2018, to October 15, 2022. The equity indices were selected to represent three large and diverse markets namely the United States, France, and India in terms of geography and economic development. We assess safe-haven assets using the daily returns of Gold and Bitcoin over the same time. Equity data was collected from Yahoo Finance, Bitcoin data from coinmarketcap.com, and Gold data from the World Gold Council website. Engle (2002) developed the DCC (Dynamic Conditional Correlation)-GARCH model, which is frequently used to assess contagion amid pandemic uncertainty or crises. Time-varying variations in the conditional correlation of asset pairings can be captured using the DCC-GARCH model. Through employing this model, we can analyse the dynamic behavior of volatility spillovers. Engle’s (2002) DCC-GARCH model contains two phases; 1. Univariate GARCH model estimation2. Estimation of time-varying conditional correlation. For its explanation, mathematical characteristics, and theoretical development, see here [insert the next link in “the word here” https://journals.sagepub.com/doi/10.1177/09711023251322578] Results and Discussion The outcomes of the parameters under the DCC-GARCH model for each of the asset pairs selected for the investigation are shown in Table 1.   First, we look at the dynamical conditional correlation coefficient, ρ.The rho value is negative and insignificant for NSE 50/Gold, NSE 50 /BTC, S&P500/Gold, and S&P500/BTC indicating a negative and insignificant correlation between these asset pairs, showing Gold and Bitcoin as potential hedges and safe havens. The fact that ρ is negative and significant for CAC 40/Gold suggests that Gold can be a safe haven against CAC 40 swings. The asset pair CAC/BTC, on the other hand, has possible diversifier behavior with ρ being positive but statistically insignificant. Next, we examine the behavior of the DCC-GARCH parameters; α and β. We find that αDCC is statistically insignificant for all the asset pairs, while βDCC is statistically significant for all asset pairs. βDCC quantifies the persistence feature of the correlation and the extent of the impact of volatility spillover in a particular market’s volatility dynamics. A higher βDCC value implies that a major part of the volatility dynamics can be explained by the respective market’s own past volatility. For instance, the NSE 50/Gold’s βDCC value of 0.971 shows that there is a high degree of volatility spillover between these two assets, with about 97% of market volatility being explained by the assets’ own historical values and the remainder coming from spillover. Thus, we see that the volatility spillover is highly persistent (~0.8) for all the asset pairs except NSE 50/BTC. The results above show that the nature of the dynamic correlation between the stock markets, Bitcoin and Gold is largely negative, pointing toward the possibility of Gold and Bitcoin being hedge/safe haven. However, a detailed analysis is needed to confirm the same by employing rolling window analysis, and we present the results in the forthcoming section. We present the rolling window results for S&P500 first. We present the regression results for Gold in Figure 1 and Bitcoin in Figure 2   Figure 1. Rolling Window Regression Results for S&P500 and Gold.Note: Areas shaded under factor 1 represent significant regression coefficients. In Figure 1, we examine the behavior of β0 (intercept term), β1, β2, and β3 (partial correlation coefficients). The intercept term β0 will give an idea about whether the asset is behaving as a diversifier or hedge. Here, the intercept term shows significance most of the time. However, during 2018, the intercept was negative and significant, showing that it could serve as a hedge during geopolitical tensions and volatilities in the global stock market. However, during the early stages of COVID-19, we show that the intercept is negative and showing statistical significance, suggesting that Gold could serve as a hedge during the initial shocks of the pandemic. These findings are contrary to the results in the study by Tarchella et al. (2024) where they found hold as a good diversifier. Later, we find the intercept to be positive and significant, indicating that Gold could act as a potential diversifier. But during the Russia-Ukraine War, Gold exhibited hedge ability again. Looking into the behavior of β1, which is the partial correlation coefficient for the tenth percentile of return distribution shows negative and insignificant during 2018. Later, it was again negative and significant during the initial phases of COVID-19, and then negative in the aftermath, indicating that Gold could act as a weak safe haven during the COVID-19 pandemic. Gold could serve as a strong safe haven for the SP500 against volatility in the markets brought on by the war in Ukraine, as we see the coefficient to be negative and large during this time. From β2 and β3, the partial correlation coefficients of the fifth and first percentile, respectively, show that Gold possesses weak safe haven properties during COVID-19 and strong safe haven behavior during the Ukraine crisis. Next, we examine the characteristics of Bitcoin as a hedge/diversifier/safe haven against the S&P500 returns. We present the results in Figure 2.   Figure 2. Rolling Window Regression Results for S&P500 and Bitcoin.Note: Areas shaded under factor 1 represent significant regression coefficients. Like in the previous case, we begin by analysing the behavior of the intercept coefficient, which is β0. As mentioned earlier the intercept term will give a clear picture of the asset’s hedging and diversifier property. In the period 2018–2019, the intercept term is positive but insignificant. This could be due to the large volatility in Bitcoin price movements during the period. It continues to be minimal (but positive) and insignificant during 2019–2020, indicating toward weak diversification possibility. Post-COVID-19 period, the coefficient shows the significance and positive value, displaying the diversification potential. We see that the coefficient remains positive throughout the analysis, confirming Bitcoin’s potential as a diversifier. Looking into the behavior of β1 (the partial correlation coefficient at tenth percentile), it is positive but insignificant during 2018. The coefficient is having negative sign and showing statistical significance in 2019, suggesting that Bitcoin could be a good safe haven in that year. This year was characterized by a long list of corporate scandals, uncertainties around Brexit, and tensions in global trade. We can observe that throughout the COVID-19 period, the coefficient is showing negative sign and negligible during the March 2020 market meltdown, suggesting inadequate safe-haven qualities. However, Bitcoin will regain its safe-haven property in the coming periods, as the coefficient is negative and significant in the coming months. The coefficient is negative and shows statistical significance during the Ukrainian crisis, suggesting strong safe-haven property. Only during the Ukrainian crisis could Bitcoin serve as a safe haven, according to the behavior of β2, which displays the partial correlation coefficient at the fifth percentile. Bitcoin was a weak safe haven during COVID-19 and the Ukrainian crisis, according to β3, the partial correlation coefficient for the first percentile (coefficient negative and insignificant). According to the overall findings, Gold is a stronger safe haven against the S&P 500’s swings. This result is consistent with the previous studies of Triki and Maatoug (2021), Shakil et al. (2018), Będowska-Sójka and Kliber (2021), Drake (2022), and Ghazali et al. (2020), etc. The same analysis was conducted for the CAC 40 and the NSE 50; the full analysis can be found here [insert the next link in “the word here” https://journals.sagepub.com/doi/10.1177/09711023251322578]. However, it is important to highlight the respective results: In general, we may say that Gold has weak safe-haven properties considering CAC40. We can conclude that Bitcoin’s safe-haven qualities for CAC40 are weak. We can say that Gold showed weak safe-haven characteristics during the Ukraine crisis and good safe-haven characteristics for the NSE50 during COVID-19. We may say that Bitcoin exhibits weak safe haven, but strong hedging abilities to NSE50. Concluding Remarks In this study, we suggested a new method to evaluate an asset’s time-varying hedge, diversifier, and safe-haven characteristics. We propose a rolling window estimation of the DCC-based regression of Ratner and Chiu (2013). Based on this, we estimate the conventional asset’s time-varying safe haven, hedging, and diversifying properties during crises like the COVID-19 pandemic and the conflict in Ukraine. For comparison purposes, we include Bitcoin, a nonconventional safe-haven asset. We evaluate Gold and Bitcoin’s safe haven, hedging, and diversifier properties to the S&P 500, CAC 40, and NSE 50 variations. We use a rolling window of length 60 to estimate the regression. From the results, we find that Gold can be considered as a better safe haven against the fluctuations of the S&P 500. In the case of CAC 40, Gold and Bitcoin have weak safe-haven properties. While Bitcoin demonstrated strong safe-haven characteristics during the Ukraine crisis, Gold exhibited strong safe-haven characteristics during COVID-19 for the NSE 50. Overall, the findings indicate that Gold is the better safe haven. This outcome is consistent with earlier research (Będowska-Sójka & Kliber, 2021; Drake, 2022; Ghazali et al., 2020; Shakil et al., 2018; Triki & Maatoug, 2021). When it comes to Bitcoin, its safe-haven feature is weak. Bitcoin, however, works well as a diversifier and hedge. Therefore, from a policy perspective, investing in safe-haven instruments is crucial to lower the risks associated with asset ownership. Policymakers aiming to enhance the stability of financial portfolios might encourage institutional investors and other market players to incorporate Gold into their asset allocations. Gold’s strong safe-haven qualities, proven across various market conditions, make it a reliable choice. Gold’s performance during crises like COVID-19 highlights its potential to mitigate systemic risks effectively. Further, Bitcoin could also play a complementary role as a hedge and diversifier, especially during periods of significant volatility such as the Ukraine crisis. While Bitcoin’s safe-haven characteristics are relatively weaker, its inclusion in a diversified portfolio offers notable value and hence it should not be overlooked. Further, policymakers may consider how crucial it is to monitor dynamic correlations and periodically rebalance portfolios to account for shifts in the safe haven and hedging characteristics of certain assets. Such measures could help reduce the risks of over-reliance on a single asset type and create more resilient portfolios that can better withstand global economic shocks. For future research, studies can be conducted on the estimation of the rolling window with different widths. This is important to understand how the safe-haven property changes across different holding periods. Further, more equity markets would be included to account for the differences in market capitalization and index constituents. This study can be extended by testing these properties for multi-asset portfolios as well. We intend to take up this study in these directions in the future. Data Availability StatementNot applicable.Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.FundingThe authors received no financial support for the research, authorship, and/or publication of this article.ReferencesAkhtaruzzaman M., Boubaker S., Lucey B.

Introduction Geopolitical tensions are making global trade increasingly difficult. In order to reduce the associated risk of default, companies are shifting their trade relations to trading partners that are politically similar to them. In the course of the beginnings of geo-economic fragmentation, politically and economically like-minded countries are also gaining in importance for German and European decision-makers. Liaison countries1 in particular can form a counterforce to the trend towards polarization in foreign trade - especially between the USA and China: they are characterized by a pronounced economic and trade policy openness that overrides differences between geopolitical or ideological camps. Consequently, the question arises: How can relevant connecting countries for Germany and Europe be identified? What opportunities and risks do closer trade relations with these countries offer in order to strengthen foreign trade resilience in geopolitically uncertain times?  With a high degree of openness - defined as the sum of imports and exports in relation to gross domestic product - of over 80 percent2 , the German economy is strongly integrated into global trade. Accordingly, the disruptive effect of geo-economic fragmentation on the German economy would be above average. The defensive strategy to strengthen Germany's economic security by pushing for trade policy independence would only reinforce geo-economic fragmentation. Against the backdrop of comparatively high economic vulnerability, it is necessary to focus on those potential partner countries with which German and European foreign trade could be developed and expanded even under the condition of increasing fragmentation.  Geoeconomic Fragmentation  The term "geo-economic fragmentation" is used to describe the politically motivated reorganization of global goods and financial flows, in which strategic, economic and political interests primarily determine the choice of countries of origin and destination for trade flows.3 In the scenario of geo-economic fragmentation, the result would be the formation of a bloc within the global community of states, which would fundamentally change the regulatory structure of global economic networking. In this case, trade and investment would probably concentrate from a previously diverse range of economic partner countries - prior to the formation of the bloc - on those countries that now - since the formation of the bloc - belong to the same bloc.  The likelihood of this scenario occurring and leading to an increased fragmentation of the global economic order has increased again in the recent past. For example, Donald Trump's second term as US president is causing increasing geopolitical uncertainty worldwide.  Statements on the concrete form of a possible demarcation of potential blocs are subject to a great deal of uncertainty. However, the division of a large part of the global economy into a "US bloc" and a "China bloc" is a conceivable scenario for which German politics and business should prepare.  Data already shows that, at a global level, foreign trade openness has decreased in the recent past. Data from the World Trade Organization (WTO) illustrates the increasing hurdles in global trade in goods. While 3.1% of global imports were still affected by tariff or non-tariff barriers to trade in 2016 - including under WTO rules - this figure rose to 11.8% in 2024 over the following years.4 This development goes hand in hand with a noticeable loss of importance and enforcement of the WTO since the 2010s, which previously played a central role as the guardian of the rules-based global economic order.  Studies by the International Monetary Fund (IMF) have already found indications of an incipient geo-economic fragmentation along potential bloc borders. It shows that trade in goods and foreign direct investment between countries that would belong to the opposing camp in the event of a bloc formation declined on average in 2022 and 2023 - in contrast to foreign trade between countries that are geopolitically close.5  In this initial phase of geo-economic fragmentation, liaison countries are beginning to establish themselves as a counterforce, holding the fragmenting global community of states together with new trade and investment routes.  Identification of liaison countries Specifically, liaison countries have the following characteristics: a pronounced openness to foreign trade in the form of a high foreign trade quota and low tariff and non-tariff trade barriers, as well as pronounced economic relations with partner countries from different geopolitical camps. The geopolitical orientation of countries can be examined using data on voting behavior within the United Nations.6 This involves analyzing whether a country can be assigned to the US or Chinese camp - or whether there is no pronounced proximity and therefore political neutrality or "non-alignment" in the sense of ideological independence. The data-based identification of connecting countries is relatively new. Empirical analyses are also limited to connecting countries in the context of US-Chinese foreign trade - specifically US imports from China. In this case, the characteristics of a connecting country can be broken down into (1) "non-alignment" - i.e. a geopolitical distance to both a Western and an Eastern bloc - as well as (2) an increase in imports and foreign investment from China and (3) a simultaneous increase in exports to the United States. In a narrower sense, this is an evasive reaction to trade restrictions, i.e. circumventing trade. If the foreign trade indicators - specifically the trade and investment data relating to the US and China - of "non-aligned" countries for the period from 2017 to 2020 show corresponding characteristic-related changes compared to previous years, these can be identified as countries connecting the US and China.  The analysis of trade data shows that the value of direct exports from China to the USA fell during Donald Trump's first term in office. At the same time, both Chinese exports to some of the "non-aligned" countries and exports from these countries to the USA have increased significantly. These countries have presumably stepped in as a link on the export route from China to the US after the previously direct trade flow was interrupted by trade barriers and had to find a new route. Companies producing in China are therefore likely to have sought new, indirect ways to maintain access to the US sales market.  A certain statistical inaccuracy in the foreign trade data makes it difficult to draw a definitive conclusion in this context. It should be noted: No single commodity can be tracked across national borders in trade data collection. Whether the additional goods imported from China actually found their way to the United States can only be assumed approximately. However, if the trade flows are aggregated, a clearer picture emerges and the circumvention trade via selected connecting countries - including Vietnam and Mexico - becomes visible.  Data on foreign direct investment rounds off the analysis.7 "Non-aligned" countries in which an increase in Chinese investment can be seen between 2016 and 2020 in addition to trade flows can be identified as connecting countries. Here, too, available data suggests that the companies concerned either exported their goods to the United States via a stopover or even outsourced parts of their production destined for the US market to connecting countries. Five connecting countries between the US and China Based on the 2017-2020 study period, various connecting countries can be empirically identified that were used to indirectly maintain access to the US market. In terms of foreign trade volume, the economically most important connecting countries include Mexico, Vietnam, Poland, Morocco and Indonesia.8 All five countries are characterized by the fact that both their exports of goods to the US and their imports of goods from China increased significantly between 2017 and 2020. In addition, greenfield investments (foreign direct investment to set up a new production facility) have risen significantly compared to the period before 2017.  However, the five countries show different priorities in their development, which differentiate them in their role as connecting countries between the USA and China. In Vietnam, exports to the USA in particular have risen sharply. China has been the most important procurement market for Vietnamese companies for years. Poland, Mexico and Indonesia are characterized as connecting countries primarily by the significant increase in imports from China. Morocco, in turn, was able to attract more Chinese foreign investment in particular. Greenfield investments have almost tripled here since 2017. However, Poland - a rather surprising candidate for the role of liaison country, as it is intuitively assigned to the US-oriented bloc - is positioned fairly centrally between the US and China according to the analysis of voting behavior within the United Nations9. In addition, Poland qualifies primarily due to the sharp rise in greenfield investments from China, primarily in the expansion of domestic battery production.10  It cannot be concluded from the previous studies on the USA and China whether German companies are also circumventing trade barriers from the USA via the countries identified. As the trade policy conflicts between the US and China differ significantly from those between the EU and China, there has been a lack of comparable empirical data to analyze connecting countries in the EU context. Opportunities and challenges As the German economy is strongly oriented towards foreign trade and is closely networked with both the USA and China, German companies play a particularly exposed role in the area of tension between the USA and China. Increased economic exchange with potential connecting countries would offer German companies an opportunity to mitigate the expected shock of a geopolitical bloc. They could at least maintain international trade to a certain extent and thus secure some of the endangered sales and procurement markets. On the other hand, there are also costs associated with expanding foreign trade relations with potential connecting countries. The greater complexity also increases the risk in the value chains. Companies that position themselves wisely within this trade-off buy themselves valuable time in the event of a shock to reorganize themselves against the backdrop of changed foreign trade conditions.  From the perspective of foreign trade policy, it is also possible to examine the extent to which stronger foreign trade cooperation with (potential) connecting countries could have advantages. The trade-off between resilience and complexity must then be assessed at a macroeconomic level, beyond individual company interests. In order to make it easier for companies to connect to potential connecting countries and to create appropriate framework conditions, German and European policy can build on existing comprehensive strategies at national and European level. Both the China Strategy11 and the National Security Strategy12 focus foreign policy on connecting countries as part of a stronger economic and political risk diversification. There is also a similar framework at European level with the EU's Strategic Compass13 . Following on from this, the German government could create targeted incentives to open up new markets in liaison countries, which would diversify critical supply chains and reduce one-sided dependencies.  At the same time, connecting countries pose a challenge. These can be used to circumvent foreign trade measures such as sanctions if flows of goods can find alternative routes via connecting countries more easily than before.  In order to realize opportunities and overcome challenges, close cooperation between science, politics and companies is required. This first requires the identification of a selection of potential connecting countries through scientifically sound analysis. This creates the basis for the subsequent steps in which European and German policymakers work closely with companies to create attractive framework conditions for trade with potential connecting countries - for example through bilateral trade agreements.  Attractive foreign trade framework conditions can create the necessary incentive to actually expand trade relations with potential connecting countries. Companies need to weigh up individual cases and make forward-looking decisions: To what extent is there a risk of a loss of production triggered by geopolitical conflicts? And how much would the complexity of the value chain increase if more potential connecting countries were included? Ultimately, the actual choice of preferred sales and procurement markets lies with the individual companies. LicenseThis work is licensed under CC BY 4.0 References1.
