In brief
Japan’s Finance Ministry said it bought a record 7.98 trillion yen in a single day on July 30, the largest yen‑buying operation on record, and that the move was part of a larger 15.4 trillion yen intervention that also included a coordinated action with the United States on July 31. The interventions came after the yen slid to its weakest level in about 40 years, leading to a temporary rebound to the low‑155 range before settling back near 158 yen per dollar.
Japan’s Finance Ministry released data on Monday that the country purchased a record 7.98 trillion yen on July 30 to support the currency, according to Xinhua. The figure, roughly 50.4 billion U.S. dollars, represents the largest single‑day yen‑buying operation on record.
The July 30 intervention was part of a multi‑day effort that also included transactions on July 31 and on August 3, bringing the total yen‑buying for the period to 15.4 trillion yen. Xinhua reported that the intervening operations were coordinated with the United States for the July 31 move, Japan’s first joint intervention with Washington in 28 years.
On July 31, Japan and the United States bought yen in a coordinated rescue that involved spending the equivalent of 5.55 trillion yen, the ministry’s data showed. The coordinated operation was launched after the yen had fallen to the upper 163 range versus the U.S. dollar, a level that was its weakest in roughly 40 years.
After the July 30 purchase, the yen temporarily rebounded to the lower 155 range on August 3, a shift that was also attributed to the intervention and other measures, Xinhua said. By September 8, the yen had briefly firmed to the 152 range, but it later fell back, trading in the mid‑158 range against the dollar, the ministry’s data indicated.
Reuters also cited the July 30 figure of 7.98 trillion yen, noting that it surpassed the previous record of 6.28 trillion yen. The outlet did not provide further details on the coordinated actions.
The Wall Street Journal highlighted the same July 30 purchase, referring to it as a record $50 billion spend in one day. The WSJ added that the Ministry’s total yen‑buying for the quarter amounted to 15.399 trillion yen.
While the official data confirms the scale of the intervention, the exact tactical motivations remain undisclosed by Japanese officials. Analysts have pointed to the sharp depreciation of the yen as a key trigger, with the currency’s decline prompting the authorities to intervene to stem a further slide.
The interventions also reflect broader market dynamics, such as the persistent interest rate differential between Japan and the United States, which continues to influence the yen’s trading range. The yen’s return to trading around 158 yen per dollar illustrates the challenges of maintaining a stable exchange rate despite large-scale market interventions.
Japan’s record intervention underscores the ongoing role of the Ministry of Finance in managing currency volatility, as the country attempts to navigate a volatile global economic environment while keeping the yen within a desired range.
