Bretton Woods needed enough dollars to support world trade and reserves, but expanding foreign dollar claims made the fixed gold-convertibility promise harder to sustain.
The system relied on the United States supplying dollar reserves while also promising official dollar-to-gold conversion at a fixed price. As foreign dollar claims grew relative to U.S. gold, those two roles became increasingly difficult to reconcile.
The problem was structural rather than a single-day policy error: global liquidity required more reserve assets, while confidence in gold convertibility required limiting claims on the gold stock.
Federal Reserve History notes that dollar claims outstanding exceeded the U.S. government’s gold stock by the early 1960s, increasing doubts about full conversion at the official price.
Reducing the end of Bretton Woods to one political announcement while ignoring the reserve-liquidity versus convertibility tension that had been building for years.
The system needed elastic dollar liquidity and credible fixed gold conversion at the same time; expanding the first weakened confidence in the second.
