On Thursday, Reuters reported that Atsushi Mimura, Japan’s vice finance minister for international affairs, warned about the pace of recent currency-market moves as the dollar hit ¥159.94 against the yen, a two-month high.
Reuters described the remarks as Mimura’s first foreign-exchange comments since late September. “It’s still too early to forget what happened this summer,” Reuters quoted him as saying.
Japan’s Ministry of Finance (MOF) records dollar sales and yen purchases of ¥7,975.6 billion on July 30, ¥5,552.3 billion on July 31 and ¥1,871.4 billion on Aug. 3, totaling ¥15,399.3 billion. The ministry said the July 31 operation was coordinated with the U.S. Treasury. It added that Japan remained in close contact with U.S. officials and did not rule out further joint intervention.
MOF monthly data show no intervention from Sept. 29 through Oct. 28, the period covered by the October zero-intervention tally. The ministry’s records do not set ¥160 as an intervention trigger. Reuters did not report a new operation alongside Mimura’s remarks.
Preliminary Bank of Japan (BOJ) data put the yen-based import price index 3.3% above September and 24.8% above October 2025. The index measures import prices in yen; Reuters has identified import costs as a concern for Japanese policymakers.
The U.S. Bureau of Labor Statistics (BLS) said the U.S. Consumer Price Index (CPI) rose 0.4% in October from the prior month, following a 0.6% rise in September. Core CPI increased 0.3%. Reuters said the inflation release and hawkish Federal Reserve comments reinforced expectations of an interest-rate increase, supporting the dollar. The BOJ’s next scheduled policy meeting is Dec. 17–18, 2026.
