The market also became cautious that the BOJ may raise interest rates soon, after U.S. Treasury Secretary Scott Bessent’s comments, he said.
In an interview with Bloomberg Television, Bessent said the BOJ is going to hike rates as it is “behind the curve” in handling monetary policy.
The comments came as rising bets that the Federal Reserve will resume rate cuts next month sent the dollar to a three-week low. A stronger yen typically weighs on exporter shares by reducing the value of overseas earnings when converted back into Japanese currency.
