Japan disclosed on Nov. 9, 2026, that it had intervened on three days over the summer to support the yen, spending ¥15.4 trillion on purchases of its currency. The Finance Ministry’s daily figures revealed one more day of action than traders had expected, Bloomberg reported in an article republished by The Business Times.
Tokyo bought a daily record ¥7.98 trillion, equivalent to $50.4 billion in the report, on July 30. Purchases of ¥5.55 trillion and ¥1.87 trillion followed on the other two days, according to Bloomberg’s account of the ministry data.
The operations involved two different approaches. Japan acted alone on July 30, a day before a Bank of Japan policy decision. On July 31, it intervened alongside the United States. The two countries had previously confirmed that joint action, their first coordinated operation specifically to support the yen since 1998.
U.S. Treasury Secretary Scott Bessent and Japanese Finance Minister Satsuki Katayama said the intervention aimed to counter disorderly currency movements and that they stood ready to act again if necessary, Bloomberg reported. That was a conditional willingness to intervene, not an announcement of another operation.
