The Ministry of Finance publishes the intervention total
Japan's Ministry of Finance published its foreign exchange intervention total for 30 July to 26 August 2026 on 28 August at 15,399.3 billion yen. The figure is the ministry's own account of its operations, not a market estimate. The ministry publishes these totals monthly for a fixed reporting period, with the daily breakdown released separately on a quarterly schedule. The monthly figure is the only non-market confirmation of how large the operations were, and that scale anchors the debate about the yen.[1]
Mexico taps the Japanese market with samurai bonds
Mexico's finance ministry SHCP sold 282.8 billion yen of bonds in the Japanese debt market, worth about 1,774 million dollars. The issue is split across four separate bonds at 3, 5, 10 and 20 years. The ministry said 85 per cent of Mexico's outstanding bond portfolio in the Japanese market is aligned with the United Nations Sustainable Development Goals, prioritising areas such as health, education, renewable energy and climate action. The same statement reported that the public sector's financial cost fell 4.8 per cent in real terms in the first half of 2026.[2]
Official yen data meets a fresh sovereign issue
The ministry's intervention account is the non-market yardstick cited in the debate over the yen's direction; daily transaction detail will follow in the quarterly release. Mexico's samurai bond sale placed yen-denominated foreign sovereign borrowing on the same market. SHCP reported its sustainable-development portfolio share alongside the real decline in public-sector financing costs in the same statement.[1], [2]
