Yen sinks to 40-year low, sparking intervention chatter and market ripples
The Japanese yen dropped to its weakest level in about four decades against the U.S. dollar as traders bet the Fed will keep rates high amid an oil-price shock from the US-Israel-Iran conflict. The Bank of Japan’s still-lower rates help explain the gap, and Tokyo has intervened before, though the yen’s slide continues. A larger move could affect U.S. Treasuries, currency flows, and carry trades, with implications for Japan’s import costs and broader global markets.
