Yen sinks to four-decade low as dollar gets yields boost

The dollar surged to a 40-year high against the yen, fueled by rising U.S. Treasury yields and anticipation of a Federal Reserve rate hike. Traders are closely watching upcoming U.S. jobs data, with expectations of further Fed tightening increasing significantly. Japanese authorities are considering intervention to support the yen, especially with a U.S. holiday approaching, which could reduce market liquidity and amplify any action.
