**Deck**: Japan’s foreign reserves fell by a record $79.6 billion in August following what was reported as record intervention to support the yen, signalling how costly efforts to stabilise the currency have become. The move underlines the trade-off between defending the yen and preserving Japan’s financial buffer.

Japan’s latest reserve figures show how much pressure its weak currency is putting on policymakers.

According to market reporting, Japan’s foreign reserves fell by $79.6 billion in August, the largest monthly decline on record. The drop followed what was described as record intervention to support the yen.

Japan holds a large stockpile of foreign assets so that authorities can act in periods of intense currency stress. A reduction of nearly $80 billion in a single month indicates that officials judged it necessary to sell a significant amount of foreign holdings and buy yen to slow its fall.

A weaker yen can benefit large exporters by boosting the value of overseas earnings once converted back into the domestic currency. But it also makes imported fuel, food and raw materials more expensive, adding to cost-of-living pressures for households and small businesses.

For policymakers, that creates a difficult balance: acting too little risks further currency weakness and higher import costs, while acting too aggressively runs down foreign reserves and can unsettle investors who watch Japan’s role as a major holder of overseas assets.

The August reserve decline also comes against the backdrop of Japan’s long-standing use of very low interest rates to support growth, even as other major economies have raised borrowing costs. The reserve data suggest authorities are now relying heavily on direct market action alongside monetary policy to contain currency moves.

Key developments to monitor include future monthly reserve figures, any further reports of yen-support operations, and signals from Japanese officials about how they intend to manage the trade-offs between currency stability, reserve levels and domestic economic conditions.
