The U.S. Treasury entered the currency market this Friday to support the Japanese yen, marking the first joint intervention with Tokyo in over a decade. The Federal Reserve Bank of New York conducted the operations, selling euros to purchase yen on behalf of the Treasury through major financial institutions including Goldman Sachs and Morgan Stanley.
This move follows extreme pressure on the Japanese currency, which recently hit its lowest levels since 1986. The intervention comes shortly after reports surfaced regarding Treasury Secretary Scott Bessent, whose notes at a recent cabinet meeting specifically mentioned a plan to buy between $5 billion and $10 billion in Japanese yen.
Japan has also been active in the markets, with central bank data suggesting significant recent efforts to bolster the yen. While the Treasury did not provide immediate comments, Japanese officials indicated they possess various tools to address market liquidity and ensure stability.
Financial analysts note that this coordinated approach aims to dampen speculative bets against the yen. Market data showed an immediate response to the news, as the dollar fell against the yen in late afternoon trading. Both nations are expected to release further policy details in the coming days to maintain this market momentum and prevent further volatility.
