The strikes on Iran by Trump-era forces are accelerating a global shift away from the dollar's uncontested dominance, according to analysts. This shift is driven by concerns over the reliability of U.S. institutions and policies, as well as the growing availability of new technological and financial solutions that make settlement and exchange cheaper and faster. Countries are quietly building a financial architecture less dependent on the United States, posing strategic and economic challenges that will shape global finance for years to come.

Why it matters

The decline in the dollar's dominance carries costs for the U.S., including a notable drop in the 'convenience yield' of U.S. Treasuries and the potential for more expensive long-term fiscal outlook. This transition reflects a broader pattern of aggressive U.S. state power that feeds a growing rebalancing away from the dollar toward a more multipolar world order.

The details

The trade-weighted dollar has fallen about 7% over the last year, reflecting not just inflation expectations and interest-rate trajectories, but also a sense that U.S. policy is less predictable and coherent than it once seemed. Discussants at a London conference argued the trajectory points toward a more complex, multi-polar system where the greenback remains dominant in trade, but without exclusive control. China's renminbi is increasingly used in international transactions, and central banks are quietly diversifying reserves away from dollars.

  • The trade-weighted dollar has fallen about 7% over the last year.
  • The share of global reserves held in dollars slipped from about 71% in 2001 to roughly 57% by late last year.

What’s next

Analysts will continue to monitor the gradual shift away from the dollar's dominance, as countries work to build more diverse and resilient financial systems less reliant on the United States.

The takeaway

The Trump-era strikes on Iran have accelerated a broader global trend of reducing heavy reliance on the U.S. dollar, as countries seek to insulate themselves from the perceived unpredictability and potential coercive use of U.S. financial power. This transition poses strategic and economic challenges that will shape the future of global finance.
