Japan confirms ¥15.4 trillion of yen-buying intervention in third quarter

Japan's Ministry of Finance put its third quarter yen intervention at ¥15,399.3 billion, selling dollars and buying yen on three days, July 30, July 31 and August 3, in its quarterly disclosure dated November 9, 2026.

Why it matters: The daily breakdown confirms the scale of Tokyo's summer defence of the yen, three operations in five days, and sets the record against which the ministry's zero intervention in the September 29 to October 28 month reads as a deliberate pause.

Data as of Japan Ministry of Finance quarterly intervention disclosure dated November 9, 2026, read in full in this run; the ministry is the source of record for its own intervention operations. Developing item.

Japan intervened on three days in the third quarter and spent ¥15,399.3 billion doing it, the Ministry of Finance said in its quarterly disclosure dated November 9. The operations sold US dollars and bought yen: ¥7,975.6 billion on July 30, ¥5,552.3 billion on July 31 and ¥1,871.4 billion on August 3, 2026.

The quarterly release is the first official daily breakdown of the summer operations. It follows the ministry’s monthly disclosure of zero intervention from September 29 to October 28, so the record now shows a concentrated three day defence in late July and early August, then no operations at all into the autumn.
