In brief
Japan’s Finance Ministry revealed a record 7.98 trillion yen buy on July 30 to support the yen, part of a 15.4 trillion yen operation that also involved a joint move with the United States on July 31 and Aug. 3. The intervention followed a sharp depreciation to its weakest level in about 40 years, after which the yen briefly recovered before falling back to around 158 USD per yen.
Japan’s Finance Ministry today released official Q3 data showing the country purchased a record 7.98 trillion yen in a single‑day intervention on July 30 to support the yen against the U.S. dollar.
Xinhua reported that the purchase, conducted in the foreign‑exchange market, was the largest single‑day yen‑buying operation on record, and that it was part of a broader series of yen‑buying and dollar‑selling operations on July 31 and Aug. 3 that totaled about 15.4 trillion yen.
Reuters confirmed the figure, noting that the July 30 operation surpassed the previous single‑day record of 6.28 trillion yen and that the Ministry’s data include a coordinated move on July 31 with the United States, Japan’s first joint intervention in 28 years.
The interventions followed a sharp yen depreciation to the upper 163 range against the U.S. dollar in late July, its weakest level in roughly 40 years.
Following the interventions, the yen briefly rallied to the lower 155 range on Aug. 3, briefly firming to a 152 range on Sept. 8 before giving back gains, ultimately trading in the 158 range against the U.S. dollar.
