Bessent’s Market Interventions Face Doubts as Yen Stays Weak
Scott Bessent is trying to influence the value of currencies and the cost of government borrowing.
He wants the Japanese yen to become stronger and the US dollar to become weaker.
He also wants long-term US interest rates to be lower.
The United States and Japan bought yen, but the amounts were small compared with the enormous global currency market.
The US Treasury also plans to buy more long-term government bonds.
The author says these actions have not changed markets very much.
The yen is still weak, and long-term bond rates have mostly gone back to where they were.
The article argues that markets are too large and powerful for small interventions to control them easily.
US Treasury Secretary Scott Bessent reportedly supported a yen intervention with Japan on July 31.
The United States may have spent $5–10 billion, while Japan reportedly contributed $53 billion.
Bessent also announced larger buybacks of long-term US Treasury bonds, potentially totaling $32 billion quarterly.
The article argues these interventions are tiny compared with the foreign-exchange and Treasury markets.
The yen remains weak and long-term bond yields have largely returned to pre-announcement levels, according to the article.
