USD share of global FX reserves
US dollar share of allocated official foreign exchange reserves (IMF COFER).
Reading
Slow-moving signal. The dollar's reserve status is the largest non-fiscal lever the US Treasury has. Reserve diversification is a path, not an event.
Thresholds
- watch55 — falls below the 2000s structural floor
- alarm50 — loss of structural majority — material reserve-status erosion
Context
Why this matters
The dollar's reserve status is the largest non-fiscal lever the US Treasury has — it underwrites the bid for Treasury issuance and the dollar's role in invoicing and settlement. Reserve diversification away from dollars happens slowly because the network effect is real (you cannot pay for oil in renminbi at scale until enough counterparties accept it), but once it moves the trend tends to be persistent. The level is not a single threshold — the trajectory and the composition of who is buying alternatives is what matters.
Who watches this
- Zoltan Pozsar (ex-Credit Suisse / now Ex Uno Plures) — "Bretton Woods III" thesis built around shifts in the reserve composition
- Luke Gromen (FFTT) — frames the question in terms of the marginal Treasury buyer disappearing
- Lyn Alden — Broken Money and her monthly newsletter track COFER closely
- Ray Dalio — the reserve-currency cycle is one of the three "big cycles" in his framework
- Brent Johnson (Santiago Capital) — the most articulate counter-view; "dollar milkshake" argues structural dollar demand persists despite the headline share decline
Recent history
The USD share fell from roughly 71% in 2000 to ~58% by 2023, then plateaued. The bulk of the diversification has gone into "other currencies" (CAD, AUD, KRW, RMB) rather than into a single alternative. Central-bank gold buying has been the largest single 2022–25 shift outside the reserve-currency basket itself.
What would change my read
A sustained move below 55% (the 2000s structural floor) would be the watch threshold. A move below 50% would be a regime change — the dollar would no longer hold a structural majority of allocated reserves. Counter: a return to the 60%+ band would suggest the diversification cycle has stalled.
