Reserve Currencies in an Evolving International Monetary System - Open Economies Review

Despite major structural shifts in the international monetary system over the past six decades, the US dollar remains the dominant international reserve currency. Using a newly compiled database of individual economies’ reserve holdings by currency, this paper finds that financial links have been an increasingly important driver of reserve currency configurations since the global financial crisis, particularly for emerging market and developing economies. The paper also finds a rise in inertial effects, implying that the US dollar dominance is likely to endure. But historical precedents of sudden changes suggest that new developments, such as the emergence of digital currencies and new payments ecosystems, could accelerate the transition to a new landscape of reserve currencies.

Short summary

The paper examines the persistent dominance of the US dollar as a reserve currency within the global economic framework, despite significant structural changes over the past sixty years. Utilizing a newly compiled database of individual economies' reserve holdings by currency, the authors find that financial links have increasingly driven reserve currency configurations since the global financial crisis of 2008-09. The paper highlights that while historical inertia maintains the US dollar's dominance, emerging technologies such as digital currencies and evolving payment systems could catalyze a shift towards a more multipolar reserve currency system.

The analysis differentiates between advanced economies (AEs) and emerging market and developing economies (EMDEs), revealing that financial links are more prominent drivers for EMDEs, whereas trade links remain significant for AEs. The paper argues that this trend towards financial considerations reflects a more integrated global economic landscape where financial markets and geopolitical factors substantially influence currency status.

Methodologically, the study employs a comprehensive empirical model using both aggregate and country-level data, emphasizing four critical determinants of reserve currency status: economic size, credibility, transactional demand, and inertia. The findings suggest a complex interplay between these factors, with inertia and financial connections playing pivotal roles in currency preference. Furthermore, the paper discusses potential future shifts driven by geopolitical changes, technological advancements, and global economic disruptions like the COVID-19 pandemic, which may impact the status quo of reserve currency holdings.

Issues (threats and opportunities)

• US Dollar Inertia: The paper highlights the US dollar's enduring dominance, emphasizing the inertial bias toward established reserve currencies. This inertia poses a threat to the adoption of alternative currencies, limiting diversity in reserve holdings.
• Emergence of Digital Currencies: The rise of digital currencies presents both an opportunity and a challenge. They could potentially disrupt traditional currency dynamics and offer more flexible and decentralized alternatives to established reserve currencies.
• Geopolitical Influences: Geopolitical tensions and strategic alliances significantly impact reserve currency configurations. Countries may adjust their holdings in response to global political shifts, affecting the stability of current reserve systems.
• Financial Linkages: The growing importance of financial connections in determining reserve currency status highlights a shift toward more integrated financial markets, impacting how countries manage their reserves.
• Exchange Rate Dynamics: The role of exchange rate stability in reserve currency choice underscores the complexity of currency management and its implications for international trade and finance.
• Impact of Global Crises: Events like the COVID-19 pandemic and global financial crises have the potential to alter economic landscapes, forcing countries to reevaluate their reserve holdings and currency strategies.
• Technological Advancements: Advances in payment systems and financial technologies may accelerate transitions to new reserve currency landscapes, challenging existing hierarchies.
• Role of Emerging Markets: The increasing economic influence of EMDEs may lead to more diverse reserve currency configurations, offering opportunities for greater representation of these economies in global finance.
• Credibility of Reserve Issuers: The perceived stability and credibility of reserve currency issuers remain crucial, affecting trust and investment decisions in international markets.
• Policy Implications: The findings underscore the need for policymakers to adapt to evolving economic dynamics and consider the potential impacts of digital currencies and geopolitical changes on reserve currency strategies.

Methodology

The authors employ an empirical model analyzing global and country-level data to identify the determinants of reserve currency status. They use data from the IMF's Currency Composition of Official Foreign Exchange Reserves (COFER) database and a new dataset of individual economies' reserve holdings by currency. The study considers four main factors: economic size, credibility, transactional demand, and inertia. Fixed effects models, along with other econometric specifications, are used to assess the significance of these factors over time and across different economies.

Results

The study's results reveal that inertia and financial links are significant drivers of reserve currency shares, with inertia being particularly influential. Financial considerations, such as currency denomination in public debt and cross-border bank claims, have become more critical post-global financial crisis. Trade links, while still relevant, appear less significant than financial connections. The findings suggest that while the US dollar's dominance is likely to persist, technological and geopolitical shifts could lead to a more multipolar reserve currency system.

Inertia and Financial Links:

• Inertia: The persistence of the US dollar's dominance is attributed to strong inertial effects. Historical ties and established use in international trade and finance create a path-dependent scenario where the US dollar remains a preferred reserve currency.
• Financial Links: The importance of financial considerations has grown, with the currency denomination of public debt and cross-border bank claims becoming crucial factors in reserve currency choice. This shift reflects a more financially integrated global economy where financial stability and liquidity are paramount.

Trade Links and Credibility:

• Trade Links: While still significant, trade connections play a lesser role compared to financial links. The study finds that trade invoicing and exchange rate alignment with reserve currency issuers have limited influence on reserve currency shares.
• Credibility: The perceived stability and credibility of reserve currency issuers continue to be essential, impacting their attractiveness as reserve holdings.

Implications

1. Policymakers: Understanding the factors driving reserve currency configurations is crucial for governments managing foreign reserves. Policymakers must consider financial market dynamics, geopolitical shifts, and technological advancements in their reserve management strategies.
2. Investors: The evolving landscape of reserve currencies offers opportunities and risks for investors. Diversifying portfolios to account for potential shifts in currency dominance can mitigate risks associated with reliance on a single currency.
3. International Organizations: Institutions like the IMF and World Bank can leverage these insights to support countries in managing their reserves effectively. Promoting financial stability and encouraging cooperation among economies may foster a more balanced reserve currency system.
