Japan Intervenes in Forex Market to Support Yen

The Government of Japan and the Bank of Japan intervened in the foreign exchange market on July 30, 2026, to combat the severe depreciation of the yen. By buying yen and selling U.S. dollars, authorities pushed the currency up by as much as 3% to 158.34, recovering from 40-year lows that had approached 164 yen per dollar.

This action followed a period of currency weakness that drove up domestic energy import costs. The intervention occurred shortly after the Federal Reserve System maintained its current interest rates. Reports indicate that U.S. monetary authorities performed a "rate check" as a preliminary step, suggesting the move was coordinated between Japan and the United States.

The market response was immediate and high-volume. Citi recorded approximately $8.1 billion in dollar/yen selling within a single ten-minute window. Finance Minister Satsuki Katayama had previously faced significant pressure to stem the decline of the currency to stabilize the national economy.
