U.S. Treasury Buys Bonds, Yen to Stabilize Markets Amid Record Debt

U.S. Treasury Secretary Scott Bessent has been busy this summer, making unexpected moves to stabilize financial markets. In mid-August, the Treasury announced it would at least double its liquidity-support buybacks for 10-to-30-year bonds, a move that came after 30-year Treasury yields reached their highest level since 2007.

The bond buybacks are not quantitative easing and won't reduce the government's overall borrowing requirements. The Treasury will purchase and retire older, less-liquid securities using cash that must be financed through revenues or additional debt issuance elsewhere.

However, signaling matters. Long-term yields fell sharply following the announcement, but much of the initial move was reversed. This intervention may be related to the currency market, as the U.S. Treasury sold euros from its Exchange Stabilization Fund and purchased yen alongside Japan's Ministry of Finance on July 31.

This marked the first coordinated effort to strengthen the Japanese currency since 1998. The yen's decline had become increasingly disorderly, intensifying imported inflation and increasing pressure on the Bank of Japan to tighten monetary policy more aggressively.
