We present a micro-founded monetary model of the world economy to study international currency competition. Our model features "unipolar" equilibria, with a single dominant international currency, and "multipolar" equilibria, in which multiple currencies circulate internationally. Long-run...

The recent period has seen an upsurge in predictions that the dollar's international dominance will at some point be challenged by a rival currency, notably the euro. This paper counters these predictions. It argues that the overestimation of the euro's ability to challenge dollar dominance is...

This paper examines recent developments in the internationalisation of the Chinese yuan, focusing on trade and portfolio flows, foreign exchange markets, cross‑border payments, and official reserve holdings. The promotion of the yuan's global role has been a deliberate policy objective for...

The US dollar (USD) has long been the dominant international currency. The euro (EUR), UK pound (GBP), Japanese yen (JPY), and other advanced economy (AE) currencies have played complementary roles to the USD as international currencies, while emerging market and developing economy (EMDE)...

This study reviews new perceptions of an imminent decline of the international role of the US dollar and implications for the euro. It considers developments in international reserves, invoicing, debt and payment systems. Strengths and weaknesses of the US and euro area economies are discussed...

This paper examines the persistence and challenges of dollar supremacy in the international monetary system, from Bretton Woods to digital stablecoins. It highlights structural supports for dollar dominance, such as deep U.S. financial markets and commodity pricing, but also explores...

This paper provides econometric evidence in support of the view that since President Trump's chaotic tariff announcements on Liberation Day, April 2, the dollar has switched from being a safe-haven currency that appreciates in times of market volatility to a "risk-on" currency that moves...

This 24th annual review of the international role of the euro presents an overview of developments in the use of the euro by non-euro area residents in 2024. This was a year that saw continuing geopolitical tensions, decreases in policy interest rates and further declines in inflation in the...

Geopolitical fragmentation triggers complex dynamics in international trade. This paper examines the effects of sanctions through the lens of a stylized model and the empirical analysis of Türkiye’s exports to Russia in the aftermath of Western measures imposed on Russia following its...

What can we learn from the high-frequency responses in bond and currency markets to the recent tariff announcement about the status of the U.S. dollar as the global reserve currency? The dollar depreciated by 6.5% after April 1 in spite of rising U.S. interest rates and market volatility, which...

This paper examines the role of foreign exchange reserve demand in mitigating inflationary pressures resulting from money supply growth in reserve currency issuing states (RCISs). Despite recurrent substantial monetary expansions in RCISs in response to recessions such as the 2000 Post-Dot Com...

The dominance of the U.S. dollar in the global financial system remains the key pillar of international trade and monetary stability but faces growing challenges in a rapidly changing world. Historically rooted in the Bretton Woods system and the establishment of the petrodollar system, the...

Recently, there has been increasing research interest in the historical composition of central bank reserves. However, studies in this area is hindered by a lack of data, as such data spanning multiple centuries is only available for a small number of countries. This paper presents an empirical...

Global uncertainty and the COVID-19 pandemic have significantly impacted the integration of emerging economies into global financial markets. Post-pandemic, the Federal Reserve's interest rate hikes have drawn investor attention to relatively independent and stable currencies. This study...

Der US-Dollar verliert an Reservewährungsdominanz. Bisher konnte der Euro davon kaum profitieren. Wir untersuchen, ob eine stärkere Internationalisierung des Euro wünschenswert wäre. Dazu analysieren wir die strukturellen Vor- und Nachteile einer Reservewährung und quantifizieren die...

This research essay explores how US dollar centrality and strength may impede decarbonization. First, I suggest that because US dollar centrality enables higher US household consumption and imports, and US household consumption is comparatively carbon-intensive, centrality can increase per...

The recent period has seen an upsurge in predictions that the dollar's international dominance will soon be challenged by a rival currency, with the euro currently tipped as the leading contender. This paper counters these predictions. It argues that the overestimation of the euro's ability to...

In this paper, we examine the prospects for, and implications of, the dollar's continued pivotal role in the international financial system. We find, first, that the dollar remains dominant by a wide margin and will likely retain its dominance for the foreseeable future-none of the other...

After decades of increasing global economic integration, the world is facing a growing risk of geoeconomic fragmentation, with potentially far-reaching implications for the global economy and the international monetary system. Against this background, this paper studies how geopolitical...

This article explores the dynamics of international currency competition and de-dollarization, focusing on the current dominance of the US dollar and potential challenges from the Chinese renminbi and BRICS countries. It reviews recent literature on currency statecraft, the political economy of...

In what ways might the digital renminbi (RMB), also known as e-CNY, bolster China's efforts to internationalize its currency? Utilizing Susan Strange's concept of currency negotiation and borrowing the concept of infrastructures from science, technology, and society studies, this article argues...

This study examines the role of the Chinese renminbi (RMB) as an international anchor currency. After China abandoned its tight US dollar (USD) peg in 2005, the RMB found greater popularity as a reserve currency. This change in the RMB's role reflected China's growing presence in the global...

What explains the US dollar's role in the global economy and the tensions affecting its likely persistence? Most analyses start from Triffin's dilemma, which accurately captured specific but partial tensions of a global monetary system based on essentially fixed exchange rates, gold backing for...

This policy brief presents a new comprehensive dataset on the currency compositions of international reserves of 64 economies from 1996 to 2023. The dataset contains country-specific shares in international reserves for the eight major international currencies, i.e. the United States Dollar...
