Japan's Ministry of Finance reported that foreign reserves fell by the largest amount on record in August, the aftermath of what officials described as record intervention to prop up the yen. Large reserve drawdowns of this kind typically reflect direct dollar-selling, yen-buying operations in the currency market.
The timing is notable because a reflationist aide to Prime Minister Takaichi projected that the Bank of Japan could raise interest rates as soon as September. Reflationists have historically favored looser policy to fight deflation, so a hike call from that camp signals confidence that Japan's inflation picture has shifted enough to tolerate tighter policy alongside currency defense.
What's unresolved is whether the Bank of Japan actually moves this month or waits, and whether the currency intervention was a one-off defense of a weak yen or the start of a sustained campaign that would keep draining reserves.
