Beyond immediate regional consequences, economists and policy-makers warn the strikes add momentum to a gradual move away from exclusive reliance on the US dollar for trade and reserves. Over the past year the trade-weighted dollar fell about 7% even as US growth and equity valuations remained robust, a pattern analysts link to shifting confidence in US policy and greater interest in alternatives. The strikes are therefore both a security event and a catalyst within a broader, long-running process of currency diversification.<\/p>\n<h2>Key Takeaways<\/h2>\n<ul>\n<li>The trade-weighted dollar has declined roughly 7% over the past year despite strong US economic performance and rising US stock prices.<\/li>\n<li>Global central banks&#8217; dollar holdings slipped from about 71% of reserves in 2001 to 57% by Q4 of last year, indicating a slow reallocation of official reserves.<\/li>\n<li>The Federal Reserve\u2019s 2007\u201308 swap lines exposed the dollar\u2019s centrality but also the leverage the US holds through financial plumbing.<\/li>\n<li>Policy tools including sanctions and Swift exclusions have heightened demand for non-dollar options among states seeking insulation from US pressure.<\/li>\n<li>Technological and institutional steps \u2014 digital currencies, enhanced repo lines and cross-border swap arrangements \u2014 are being developed to reduce dependency on the dollar.<\/li>\n<li>IMF projections cited in reporting suggest US public debt could reach about 130% of GDP within five years, a factor that may erode the &#8220;convenience yield&#8221; on Treasuries.<\/li>\n<li>BRICS and other groupings are exploring reciprocal arrangements and payment linkages that could make trade less dollar-dependent.<\/li>\n<\/ul>\n<h2>Background<\/h2>\n<p>Since World War II the US dollar has been the primary vehicle for international trade and reserves, a status reinforced by deep, liquid markets in Treasuries and the dollar&#8217;s role in commodity pricing. That centrality has long given Washington economic advantages: lower borrowing costs and considerable influence over global finance. However, that dominance has never been static; it has evolved with geopolitical shifts, technological change and the policy choices of other major economies.<\/p>\n<p>Two structural forces have accelerated talk of diversification. First, the routine use of sanctions and restrictions\u2014freezing assets or excluding actors from payment rails\u2014has made some governments wary of concentrated dollar exposure. Second, technological innovations and new institutional arrangements have lowered the cost of building alternative systems for settlement and reserves management. Together, these forces encourage gradual shifts rather than sudden replacement of the dollar.<\/p>\n<h2>Main Event<\/h2>\n<p>On 1 March 2026 the White House authorised strikes against Iranian military positions, an operation the Pentagon termed Operation Epic Fury. Officials said the strikes were a response to a recent escalation in confrontations; critics argued they reflected a disruptive, unilateral posture by the US. The immediate military impact on Iran\u2019s capabilities will take time to assess, but the political fallout has been swift: allies and adversaries alike registered concern about regional escalation and the readiness of diplomatic channels.<\/p>\n<p>Financial markets reacted to the heightened geopolitical risk in mixed ways. Investors sought safe assets, and US Treasuries remained a primary refuge in volatile moments, pushing yields lower on the day of the strikes. At the same time, currency strategists noted that the dollar\u2019s broader slide over the past year suggests market participants are weighing longer-run structural questions about US policy credibility alongside short-term flight-to-safety flows.<\/p>\n<p>Policy-makers and central bankers attending a London conference convened by the Centre for Inclusive Trade Policy described the strikes as one data point in a pattern that includes tariffs and selective interventions. Their discussion highlighted an emerging consensus: no single currency is poised to replace the dollar outright in the near term; instead, a more multipolar currency landscape is becoming likelier, shaped by regional blocs and bespoke arrangements.<\/p>\n<h2>Analysis &#038; Implications<\/h2>\n<p>The immediate implication of the strikes is geopolitical: increased instability in the Middle East and higher premiums for risk in certain markets. But the financial implications are more structural. The dollar\u2019s retreat against a trade-weighted basket\u2014about 7% over the year\u2014reflects not only interest-rate expectations but also political and policy uncertainty that can erode confidence in a reserve currency over time.<\/p>\n<p>For Washington, gradual de-dollarisation carries fiscal and strategic costs. Economists at the Federal Reserve Bank of St. Louis and others have documented a falling &#8220;convenience yield&#8221; on Treasuries, meaning the implicit benefit the US enjoys from issuing the world\u2019s preferred safe asset is weakening. With US deficits and public debt projected to rise\u2014IMF estimates point toward debt ratios that could reach roughly 130% of GDP within five years\u2014the budgetary cushion that came with dollar dominance may shrink.<\/p>\n<p>At the same time, alternatives are becoming more feasible. The ECB\u2019s decision to strengthen repo arrangements and offer standing facilities signals an institutional willingness to act as lender of last resort in euros; China\u2019s promotion of the renminbi and experimentation with a digital yuan create additional pathways for trade settlement. These are incremental moves, but cumulatively they lower the switching costs for countries seeking to diversify reserves or invoicing currencies.<\/p>\n<p>Political reaction is a key wild card. The use of financial tools as leverage\u2014sanctions, Swift restrictions, secondary measures\u2014drives other states to seek insurance. That may produce a patchwork of regional mechanisms and digital-asset linkages rather than a single multilateral alternative. Such fragmentation could raise transaction costs and complexity for global trade, with uncertain effects on liquidity and volatility.<\/p>\n<h2>Comparison &#038; Data<\/h2>\n<figure>\n<table>\n<thead>\n<tr>\n<th>Year\/Period<\/th>\n<th>Share of global reserves in USD<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>2001<\/td>\n<td>71%<\/td>\n<\/tr>\n<tr>\n<td>Q4, last year<\/td>\n<td>57%<\/td>\n<\/tr>\n<\/tbody>\n<\/table><figcaption>Official reserve allocations show a gradual decline in dollar share from 2001 to the end of last year.<\/figcaption><\/figure>\n<p>That shift in reserve composition is modest in pace but meaningful in scale: a 14-percentage-point decline over roughly two decades. Coupled with a roughly 7% fall in the trade-weighted dollar over the past year, the figures indicate both official and market-level adjustments. These statistics do not imply an imminent collapse of the dollar, but they do point to a less concentrated international monetary system over time.<\/p>\n<h2>Reactions &#038; Quotes<\/h2>\n<blockquote>\n<p>\u201cGreat powers have begun using economic integration as weapons,\u201d<\/p>\n<p><cite>Mark Carney, speech at Davos (public statement)<\/cite><\/p><\/blockquote>\n<p>Carney\u2019s warning at Davos has been frequently cited to describe the phenomenon of &#8220;weaponised interdependence&#8221;\u2014whereby financial and trade ties are used as leverage in geopolitical competition.

It can take many forms: shifting invoicing for trade into other currencies, diversifying reserve holdings, setting up currency swap lines, or launching interoperable central bank digital currencies. The drivers include geopolitical risk, sanctions exposure, macroeconomic policy divergence and the development of new payment technologies. De-dollarisation rarely happens overnight; instead it proceeds through incremental policy choices and market adjustments.<\/p>\n<\/details>\n<\/aside>\n<\/h2>\n<h2>Unconfirmed<\/h2>\n<ul>\n<li>Whether Operation Epic Fury will prompt any immediate, coordinated BRICS financial measures in the coming weeks remains unconfirmed; public statements indicate discussion but no formal commitments yet.<\/li>\n<li>The extent to which the March strikes directly accelerated central-bank reallocation plans is not independently verified; many reserve shifts predate the incident and reflect multi-year strategies.<\/li>\n<\/ul>\n<h2>Bottom Line<\/h2>\n<p>The Trump administration\u2019s strikes on Iran are another moment in a sequence of US policy choices that, collectively, are encouraging other states to seek alternatives to unilateral reliance on the dollar. The process is gradual: official reserve shares and market currency baskets are adjusting, but the dollar remains central to global finance and Treasuries retain safe-haven status in times of acute stress.<\/p>\n<p>Over the medium term, a more multipolar currency system is plausible \u2014 one characterised by greater regionalization, interoperable digital arrangements and explicit swap facilities \u2014 but it will increase complexity for global commerce and may raise costs for both private firms and publics. For Washington, preserving the advantages of dollar centrality will require more predictable macro policy and restraint in the use of financial coercion; absent that, the fiscal and strategic benefits of dominance may erode further.<\/p>\n<h2>Sources<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.theguardian.com\/world\/2026\/mar\/01\/trump-world-slow-drift-dollar-dominance-iran-strikes-currency\" target=\"_blank\" rel=\"noopener\">The Guardian \u2014 Heather Stewart (news analysis)<\/a><\/li>\n<li><a href=\"https:\/\/www.imf.org\" target=\"_blank\" rel=\"noopener\">International Monetary Fund (official projections and fiscal analysis)<\/a><\/li>\n<li><a href=\"https:\/\/www.ecb.europa.eu\/press\/pressconf\/2025\/html\/index.en.html\" target=\"_blank\" rel=\"noopener\">European Central Bank (ECB) \u2014 repo and liquidity facility announcements (official)<\/a><\/li>\n<li><a href=\"https:\/\/www.stlouisfed.org\/research\" target=\"_blank\" rel=\"noopener\">Federal Reserve Bank of St. Louis (research on &#8220;convenience yield&#8221; and Treasuries)<\/a><\/li>\n<li><a href=\"https:\/\/www.weforum.org\/agenda\/\" target=\"_blank\" rel=\"noopener\">World Economic Forum \/ Davos coverage (Mark Carney speech summary, public)<\/a><\/li>\n<\/ul>\n<\/article>\n","protected":false},"excerpt":{"rendered":"<p>On 1 March 2026, President Donald Trump ordered air strikes on Iranian targets\u2014labelled by the Pentagon as Operation Epic Fury\u2014intensifying instability across the Middle East and prompting fresh debate about the United States&#8217; role in the global financial order.
