Japan foreign reserves fall a record $80 billion

Japan's foreign reserves stood at $1.207 trillion in August, down from $1.287 trillion in July, an $80 billion drop. CNBC reported the finance ministry figures on 7 September 2026. The monthly decline was 6.18 percent, the fastest pace since ministry records started in 2000, beating May's 5.58 percent, and the fourth straight month of decline.

This is a CNBC report on Japan's Ministry of Finance monthly foreign-reserve release and related intervention tallies. It is not an IMF program, and it is not a Bank of Japan rate decision.

The ministry release, as CNBC describes it, did not state the reason for the drop. Kyodo News cited an unnamed finance ministry official saying the decline came from interventions to prop up the yen and from a fall in government-bond values after yields jumped. State Street's Masahiko Loo told CNBC the decline was primarily from recent dollar-selling, yen-buying FX interventions, and that it "reflects policy action rather than financial stress."

Tokyo bought about 11.73 trillion yen ($75.26 billion) in April and May, then ran a larger 15.4 trillion yen intervention at the end of July, with the United States selling euros to support the yen. Combined year-to-date spending of 27.1 trillion yen is the largest yearly intervention amount on record, above 20.4 trillion yen in 2003. The move with Washington was the first coordinated US-Japan intervention to support the yen since 1998.

The yen had hit a 40-year low of 163.98 on 23 July. CNBC said it traded around 155.98 against the dollar at publish time.

Reserve and intervention books sit next to other official-sector flows, including Norway's planned Treasury cut and the September FOMC hold-or-hike window. Energy and sanctions tapes still move the same dollar book, from EU winter gas storage to Hormuz-linked oil shocks.

If you mark yen, JGBs, or official FX reserves, treat the $80 billion print as a Ministry of Finance stock figure. Keep the intervention story as Kyodo plus strategist colour, and use the 27.1 trillion yen year-to-date record (versus 20.4 trillion in 2003) as the policy-action number rather than a stress signal.
