Every decade announces the dollar's decline; every decade the dollar disappoints the announcers.

The brief

The U.S. dollar is the world's reserve currency — as of the mid-2020s about 58% of global central-bank reserves, about half of international trade invoicing, and about 90% of foreign-exchange transactions on at least one side, the unit in which oil is priced and most international debt is denominated. Every decade announces the dollar's decline. The yen's rise in the 1980s, when soaring Tokyo land prices became an emblem of apparent Japanese ascendancy; the euro's launch in 1999 as a continental rival; the BRICS' recurring announcements of an alternative payment system; the post-2014 weaponization of dollar clearing that drove Russian and Chinese reserve diversification — every decade the dollar disappoints the announcers. The current cycle is no different in form, though it may be different in degree.

The dollar's role is sustained by network effects that are extremely hard to dislodge. Trade is invoiced in dollars because most trade is invoiced in dollars; central banks hold dollar reserves because dollar markets are deepest and most liquid; oil is priced in dollars because Saudi Arabia and the rest of OPEC have invoiced in dollars since long before the 1974 understanding with Washington. Each leg of the system reinforces the others, and the U.S. Treasury market — approaching $30 trillion by the mid-2020s, the only pool deep enough to absorb the world's surpluses — is the keystone. Dislodging the dollar would require not just a better technical alternative (the euro is technically credible but politically fragmented, lacking a unified eurozone safe asset; the yuan is too tightly capital-controlled to function as a reserve) but also an entire matching ecosystem of banks, legal systems, and trust networks built over generations. Recent trends do suggest gradual erosion. Russia, after the 2022 sanctions, lost access to roughly $300 billion of foreign-exchange reserves held abroad — a shock that re-priced the political risk of reserve assets for states that might at some point be sanctioned. Central banks have been buying gold at record rates, over 1,000 tonnes a year since 2022, led by China, Turkey, and India. China has built CIPS (a parallel cross-border payment system) and pushed yuan settlement in bilateral trade, including Russian energy. The aggregate: the dollar's share is slowly slipping — reserves down from about 70% in 2000 to roughly 58% — while no single successor is rising to take its place.

Why nowThe current dollar system is in a Goldilocks problem in reverse: too strong to be replaced, too weaponized to be trusted, too important to ignore. The de-dollarization of the next decade is likely to be partial — more multipolar reserve baskets, more bilateral non-dollar trade settlement, more gold, more local-currency swap lines — rather than wholesale. Whether American fiscal trajectories (gross federal debt above 120% of GDP as of 2025, and rising), an ever-wider sanctions perimeter, or domestic political instability eventually produce a step-change — a sudden loss of confidence rather than gradual diversification — is a major tail risk in international economics, and one of the most resistant to forecasting.
