US Treasury Defends Yen from Four-Year Low with Rare Market Intervention

The U.S. Treasury has intervened in currency markets for the first time in 15 years to defend the yen, which hit a four-year low against other major currencies.

The intervention was a joint effort between the U.S. and Japanese governments, aimed at stabilizing the yen's value against the dollar.

The yen has been weakening against the dollar for years due to market expectations that the Federal Reserve will raise interest rates to combat inflation resulting from the Iran war-related oil shock, as well as the Bank of Japan holding its benchmark interest rate low for years.

The U.S. intervention helped stabilize the yen's value and is also a self-interested move, as it prevents a decline in Treasury prices and an increase in yields on U.S. government securities held by Japan.
