On Tuesday, August 4th, 2026, the United States and Japan coordinated an intervention to stabilize the Japanese yen. The intervention involved Washington lending dollars to Tokyo using US Treasury bonds as collateral. This approach was designed to prevent a potentially disastrous sell-off of Treasurys by Japan amid currency market pressures.

Both Treasury Secretary Scott Bessent and Japanese Finance Minister Satsuki Katayama referenced the use of a repurchase (repo) facility as part of this coordinated effort. By lending dollars secured with Treasurys, the US provided liquidity to Japan without forcing Tokyo to liquidate its Treasury holdings, thus maintaining stability in both currency and debt markets.

This pragmatic financial arrangement reflects a practical dimension behind the public display of cooperation between the two countries.
