Trump’s Strikes on Iran Accelerate De-Dollarization Trend

Donald Trump’s recent military strikes on Iran, conducted in conjunction with Israel, represent more than just a display of force. They are accelerating a long-term shift away from the global dominance of the U.S. Dollar, potentially reshaping the international financial landscape in ways that may diminish Washington’s influence.

Dollar’s Declining Influence

Despite continued U.S. Economic growth and strong stock market performance, the trade-weighted dollar has lost 7% of its value over the past year. This decline isn’t solely attributable to inflation or interest rate expectations, but also reflects a growing perception that U.S. Policy is becoming less predictable and reliable.

Rather than a single currency replacing the dollar, as the dollar replaced sterling after World War II, a more complex, multipolar system is emerging. International trade remains overwhelmingly denominated in U.S. Dollars, though the use of China’s renminbi is increasing, actively encouraged by Beijing.

Central Banks Diversify Reserves

Global central banks have been quietly reducing their dollar reserves. The share of foreign currency reserves held in dollars has fallen from 71% in 2001 to 57% by the final quarter of 2025. This trend began in 2007-08 when the U.S. Federal Reserve established swap lines to provide dollars to select countries during the global financial crisis, highlighting the leverage the U.S. Holds due to the dollar’s central role in the world economy.

Weaponized Interdependence and the Search for Alternatives

The increasing use of economic sanctions – including asset freezes and exclusion from the SWIFT international payment system – has underscored the risks of “weaponized interdependence.” This has fueled the search for alternatives to the dollar. As Canadian Prime Minister Mark Carney warned at Davos, great powers are increasingly using economic integration as a tool for coercion.

Technological advancements are also facilitating the development of alternative financial infrastructure, making settlement and exchange cheaper and faster. The European Central Bank’s recent plans to expand its repurchase (repo) arrangements, offering euros to other central banks in times of crisis, are a step in this direction, aiming to provide a lender of last resort function and bolster the euro’s viability.

BRICS and Emerging Financial Linkages

The BRICS nations (Brazil, Russia, India, China, and South Africa, along with recent members) have long sought to reduce the dollar’s dominance. While a unified “BRICS currency” remains a theoretical concept, discussions are underway to establish financial linkages that bypass the U.S., including swap lines and interoperable central bank digital currencies.

Implications for the U.S.

Diminishing dollar dominance carries potential costs for the U.S. Research indicates a decline in the “convenience yield” of U.S. Treasuries – the benefit of their liquidity and safety – potentially increasing borrowing costs for the U.S. Government. The U.S. National debt, projected to reach 130% of GDP within five years, exacerbates these concerns.

Despite these trends, U.S. Treasuries remain a safe haven for investors during times of uncertainty, as evidenced by falling yields following recent market anxieties. However, Trump’s foreign policy decisions and the increasing perception of U.S. Unreliability are accelerating the move towards a more diversified global financial system.
