Bessent Intervention Sparks Rate Hike Expectations for BOJ

The recent joint intervention in currency markets by Tokyo and Washington has raised questions about the influence of the US on Japan's monetary policy. U.S. Treasury Secretary Scott Bessent's public views have been seen as a nudge for the Bank of Japan to raise interest rates at its September meeting.

Bessent's comments, made in interviews with NHK and CNBC, suggest that he is confident BOJ Governor Kazuo Ueda will take action to address market fears of inflation overshoot. Bessent urged Japan to follow up intervention with 'policy and fundamentals' to address the undervaluation of the yen.

Kazuo Momma, a former BOJ executive, said that while the joint intervention has given the BOJ a free hand to raise rates, there is still concern about the precedent set by US pressure on Japanese policy. The BOJ's independence from political interference is guaranteed by law, but it also requires close coordination with the government's economic policy.
