United States and Japan coordinate major yen intervention

The United States and Japan have conducted a significant, coordinated intervention in the foreign exchange market to support the Japanese yen, marking the first joint operation of its kind since 1998. The U.S. Treasury, through the Federal Reserve Bank of New York, purchased between $5 billion and $10 billion in yen using euros to avoid selling U.S. Treasuries. Japan contributed more than $36 billion to the effort to counter the yen's decline to 40-year lows.

A primary driver for U.S. involvement is the protection of the American bond market. As Japan is a major holder of U.S. Treasuries, a collapsing yen could force the Bank of Japan to sell these holdings to fund currency support, which would spike U.S. interest rates. To mitigate this, the Federal Reserve utilized a mechanism where it provides dollars to Japan in exchange for temporary ownership of Treasury securities via repo agreements.

The operation has drawn criticism from European officials and financial institutions. The European Central Bank was reportedly notified only after the operation was complete, with some sources describing the move as a breach of strategic agreements with allies. Additionally, BlackRock warned that the surprise maneuver increases geopolitical uncertainty and may reduce the long-term appeal of government bonds.
