Japan’s foreign exchange reserves fell in September 2026, easing to USD 1,178.4 billion from USD 1,207.5 billion in August, according to data updated on 6 October 2026. The move represents a decline of USD 29.1 billion over the month.
The softening in reserves brings them down from August’s higher base, suggesting a measurable but not yet quantified shift in Japan’s external buffer position heading into the final quarter of 2026. While the underlying drivers of the September change were not specified, investors are likely to watch upcoming releases closely for signs of whether this marks the beginning of a trend or a temporary adjustment in the country’s reserve management.
