Japan’s decision to hold oil reserve releases despite falling imports signals confidence in stable supply and limits near‑term upward pressure on crude prices
Executive summary: Japan’s economy minister said oil imports for next month are expected at 80% of the 2025 average and confirmed that no additional crude will be released from the strategic petroleum reserve. The decision indicates that authorities view current supply as sufficient, which can influence crude price expectations and preserve reserves for future disruptions.
Who is involved: Japan’s Ministry of Economy, Trade and Industry (METI), economy minister Ryosei Akazawa, and the country’s strategic petroleum reserve administrators.
Likely next: METI will monitor September import data and may review reserve levels if imports fall below a defined threshold, while the Bank of Japan will assess inflation trends ahead of its September policy meeting.
Japan’s economy minister Ryosei Akazawa said the country expects oil imports next month to be 80% of the 2025 monthly average and confirmed that no additional crude will be released from the strategic petroleum reserve. The statement follows a September import drop and comes amid stable domestic demand and adequate inventory levels. Analysts note that the decision reduces near‑term upward pressure on international crude prices while preserving reserves for potential future supply shocks.

Regulatory implications
- Japan’s Oil Stockholding Law (Act No. 57 of 1979) requires METI to evaluate reserve releases when imports fall below 80% of the baseline monthly average.
- METI’s monthly oil import monitoring triggers a formal review process for strategic petroleum reserve releases.
- Bank of Japan’s policy decisions are guided by the Bank of Japan Act, which mandates price stability and influences monetary tightening when inflation exceeds the 2% target.
Historical parallels

- June 2020: Japan tapped its strategic petroleum reserve, releasing about 500,000 barrels per day, in response to the COVID‑19‑driven demand collapse.
- October 2018: Japan considered a reserve release after typhoon‑related supply disruptions but ultimately maintained existing reserve levels.
