The euro’s global footprint is edging higher, but the currency still sits comfortably in second place behind the US dollar in almost every key metric of international use.[4][8] For traders and issuers, that mix of gradual progress and entrenched hierarchy matters for how they think about long-dated FX positions, euro bond funding strategies, and currency futures hedging.[4][7][8]
Global Currency Landscape: Dollar Versus Euro
For more than eight decades, the US dollar has been the anchor of the international monetary system and the dominant reference point for trade, finance, and reserves.[5][14] Recent studies show the dollar is involved in close to 90% of global foreign-exchange transactions and accounts for more than half of global export invoicing, cross-border banking claims, and international debt securities.[3][14] Dollar assets still represent around 60% of the value of foreign reserve holdings worldwide, underscoring its role as the primary safe asset in global portfolios.[3][7][14]
Against that backdrop, the euro has established itself as a clear but distant runner-up.[6][8][15] It is the second most important international currency across a broad range of indicators, ahead of the yen, the pound and the renminbi, but well behind the dollar’s global reach.[8][12][15] The euro is involved in around a third of FX transactions, accounts for up to a quarter of cross-border banking claims, and dominates trade invoicing within Europe and parts of Africa.[3][12] Yet its relevance in the rest of the world remains modest compared with the dollar.[3][13]
HOW MUCH HAS THE EURO REALLY GAINED?
Latest data from the European Central Bank (ECB) show that the euro’s international role has grown moderately, with its share across various indicators of global currency use reaching around 20% in 2025.[4][18] This composite measure, which averages the euro’s share in reserves, debt issuance, loans, deposits, FX turnover and global payments, had been broadly stable around 19% in recent years and is now edging a little higher.[4][7][14]
In official foreign-exchange reserves, the euro’s share is hovering at about 20%, essentially unchanged but solidly in second place.[4][7][15] The US dollar’s share in global reserves has declined gradually over the past decade, from around 71% in 1999 to just under 60% more recently, but the shift away from the dollar has been spread across several currencies rather than flowing primarily into the euro.[2][7][14] Research indicates that only about a quarter of the reduction in dollar reserves has gone into the Chinese renminbi, and the remainder has moved into a mix of smaller currencies, leaving the euro’s share broadly unchanged.[2][8]
In payments, SWIFT data show the euro ranks second with about 22% of global payment flows, compared with roughly 50% for the dollar.[13][14] The ECB’s own statistics confirm the euro’s stable role in global payments, with euro transactions involving non-euro area banks representing a significant share of volumes on major payment platforms.[7][14]
The key takeaway is that the euro is gaining marginal ground in a multi-currency system, but the change is evolutionary rather than revolutionary: an incremental rise around the 20% mark while the dollar remains the dominant currency with roughly 55–60% share across major indicators.[4][7][11][14]
Structural Factors Limiting Euro Ascent
The euro’s inability to close the gap with the dollar is not merely a function of short-term policy choices; it is rooted in structural features of the euro area.[2][5][15] Analysts highlight several constraints:
First, the US still offers a uniquely deep, unified capital market backed by a large supply of safe, highly liquid government bonds, which underpins the dollar’s central role in global portfolios.[5][14][15] In contrast, the euro area has multiple sovereign issuers and has historically lacked a single, large pool of joint euro-denominated safe assets, although recent EU-level issuance has started to move in that direction.[10][15]
Second, the euro area’s institutional setup—shared monetary policy but fragmented fiscal regimes—has made investors cautious since the sovereign debt crisis, contributing to the plateau in the euro’s international role.[15][2] Studies find that, after initial optimism in the early 2000s, the euro’s global share stagnated, particularly following the euro area crisis, and has remained broadly unchanged in recent years.[15][2]
Third, geopolitical considerations favor the dollar as the default transaction and reserve currency, especially in times of stress, because of the perceived stability of US institutions and the established network effects in trade, finance, and commodity markets.[5][14][19] Once a currency becomes the standard for invoicing and settlement, switching costs are high, which reinforces the dollar’s entrenched dominance.[3][14]
Implications For Fx Positioning And Long-dated Trades
For FX traders and portfolio managers, the euro’s slight gain within a still dollar-dominated system has several practical implications.[4][7][8]
In long-dated FX positioning, the structural picture suggests that dollar-centric strategies remain justified, but the case for measured diversification into euro exposures continues to build.[7][8][14] The euro’s stable, roughly 20% share in reserves and international finance signals a durable role as a secondary anchor, which can be used to balance portfolios against dollar-specific risks such as US fiscal debates, policy shifts, or sanctions-related spillovers.[4][7][8]
For euro-denominated bond issuance, the currency’s entrenched second-place status is supportive for issuers seeking broad international investor bases.[3][4][15] A steady share of global reserves in euros implies enduring demand from central banks and official institutions for high-quality euro assets, which can help maintain depth and liquidity in euro sovereign and supranational markets.[4][7][15] Corporate issuers tapping euro markets benefit from access to a large pool of investors who benchmark against euro indices, while investors gain another avenue for duration and credit exposure away from the dollar.[3][8][10]
In FX futures and options, the fact that the euro remains the second most traded currency globally anchors liquidity in EUR pairs and deepens the derivatives complex around EUR/USD.[4][14][15] For hedgers, this means efficient pricing and tight spreads in major euro crosses, making it attractive to use euro futures to manage long-horizon currency risk on European assets or mixed currency portfolios.[3][4][14] Even as the euro’s global role rises only slightly, robust turnover ensures that speculative and hedging strategies in simulated and live trading environments can be executed with relatively low transaction costs.
WHAT EURO’S TRAJECTORY MEANS FOR SIMULATED AND REAL MARKETS
In both real and simulated markets, the euro’s gradual rise within a still dollar-centric system encourages scenario-based thinking rather than binary bets on “dollar collapse” or “euro supremacy.”[8][14][19] Traders can use simulated finance platforms to stress-test portfolios under different long-run currency configurations: a continued dollar-dominated world, a more multipolar system where the euro and other currencies gain share, or episodes where geopolitical or policy shocks temporarily weaken dollar demand.[8][14][19]
For long-dated FX strategies, this means building frameworks that combine cyclical drivers—growth, inflation, rate differentials—with structural variables such as reserve composition, safe asset supply, and regulatory changes in European capital markets.[4][7][15] Issuers and investors in euro-denominated bonds can similarly explore how incremental changes in the euro’s role might affect funding costs, investor bases, and hedging needs over multi-year horizons.[4][10][15]
The overarching message from the latest data is that the euro is slowly strengthening its position as the world’s second currency, but the dollar’s dominance remains a defining feature of the global financial architecture.[4][7][8][14] For market participants, the opportunity lies not in betting on an abrupt regime change, but in thoughtfully calibrating diversification away from pure dollar exposure—using the euro as a key, but still secondary, pillar in long-term FX, bond, and futures strategies.
