Treasury Intervention Raises Questions About Credibility

The U.S. Treasury has been taking an increasingly active role in financial markets, raising questions about its credibility and the limits of market intervention.

U.S. Treasury Secretary Scott Bessent announced that the Treasury would double the size of its liquidity-support buybacks for 10-to-30-year bonds in mid-August, a move that came shortly after 30-year Treasury yields reached their highest level since 2007.

The bond buybacks are not quantitative easing and will not reduce the government's overall borrowing requirements. However, they may be seen as an attempt to manipulate yields rather than improve liquidity, which could lead to higher term premiums for investors.

The Treasury also joined Japan in a coordinated intervention to support the yen in July, with the U.S. selling euros from its Exchange Stabilization Fund and purchasing yen alongside Japan's Ministry of Finance. This marked the first coordinated effort to strengthen the Japanese currency since 1998.
