The Genoa system of 1922 transformed trade deficits by allowing USD and GBP to be held as reserves and recycled into debtor-country debt, delaying the credit tightening that gold outflows once imposed. Jacques Rueff called this a “deficit without tears.” Today, Japan’s reserve drawdowns and China’s preference for gold over U.S. Treasuries are reversing that process, transmitting trade imbalances back into the U.S. credit structure through higher rates, duration pressure, and a weaker dollar.
Many view Japan’s FX interventions as a form of QT. They are not. The Bank of Japan is not selling U.S. Treasuries because it owns very few of them; the seller is the Ministry of Finance. USTs are simply converted into USD cash and transferred to Japanese banks in exchange for yen. The temporary reserve drain at the BoJ is quickly reversed as the MoF spends the yen back into the system. The “failed intervention” narrative is largely a misunderstanding of balance sheets and settlement timing.
