Japan must fix 'misunderstanding': ex-BOJ chief

Japan must fix "any misunderstanding" held by US President Donald Trump that its central bank was intentionally weakening the yen with monetary policy, former Bank of Japan (BOJ) governor Haruhiko Kuroda said.

Trump said on Monday he had told Japan and China they could not continue to reduce the value of their currencies, as doing so would be unfair to the United States. Asked about Trump's comment on Friday night, Kuroda told a Japanese television interviewer there were limits to what Japan could do to prop up the yen if the dollar were to rise on prospects of higher US inflation from Trump's planned tariffs.

"In fact, the Japanese government has been making huge efforts to prevent the yen from weakening," such as by intervening in the exchange rate market to support its currency, Kuroda said. After a prolonged period of ultra-easy policy, the BOJ has begun raising interest rates, while the government made rare currency market interventions in 2022 and last year to boost the yen, which in July hit a 38-year low near 162 to the dollar. The dollar ended this week around 148 yen.

"The BOJ is not intentionally guiding the yen lower with monetary policy. If there's any misunderstanding on that point, it needs to be addressed," Kuroda said.
