U.S. and Japan jointly intervened to support the yen after it hit 40-year lows

The U.S. and Japan confirmed joint currency intervention to arrest the yen's slide to 40-year lows against the dollar. The yen climbed against the dollar and euro on August 3, 2026. Earlier solo Japanese action had set a floor near 160 per dollar without lasting effect. The Treasury had informed banks it might trade, though officials have not committed to a sustained campaign.
