Japan’s Producer Price Index eased from a revised 7.7% to 7.6% y/y in August, but remained above the 7.4% consensus, keeping wholesale inflation at an elevated level. On a monthly basis, PPI swung from a revised 0.4% increase to a 0.2% decline, weaker than expectations for no change. The monthly fall was led by electric power, gas and water, agriculture and fishery products, and petroleum and coal products, while higher nonferrous metals prices provided the largest positive contribution.
Imported price pressure also moderated during the month. The Yen-based Import Price Index slowed from 29.3% to 24.8% y/y and fell 3.0% m/m, while import prices on a contract-currency basis eased from 17.8% to 16.7% y/y and dropped 1.0% m/m. The official data also show the Yen appreciated 2.4% over the month, helping reduce the domestic-currency cost of imports. Even so, double-digit annual import inflation indicates that accumulated external cost pressure remains substantial.
The report therefore points to some monthly relief without a decisive easing in Japan’s inflation pipeline. That keeps wholesale prices relevant ahead of next week’s BoJ meeting, particularly as BoJ Governor Kazuo Ueda has highlighted producer prices as an indicator of how strongly firms may pass higher costs through to consumers. Reuters said markets have almost fully priced a hike from 1.00% to 1.25%, while economists it surveyed expect another increase to 1.75% by Q2 2027. August PPI does not show renewed acceleration, but its persistence above 7% gives the BoJ little evidence that upstream price pressure has subsided.

Key Takeaways
- Japan’s Producer Price Index eased only marginally from 7.7% to 7.6% y/y, still above the 7.4% consensus, keeping annual wholesale inflation elevated.
- Monthly PPI reversed from 0.4% to -0.2%, with electricity, gas, agricultural products and petroleum-related prices among the largest negative contributors.
- Import-cost pressure eased more visibly. Yen-based import prices slowed from 29.3% to 24.8% y/y and fell 3.0% m/m.
- The Yen appreciated 2.4% m/m, helping lower import prices in domestic-currency terms.
- Even after August’s cooling, import prices remained up 24.8% y/y in Yen terms and 16.7% in contract-currency terms, leaving the upstream inflation pipeline elevated.
- With markets near fully pricing a BoJ hike to 1.25% next week, the data provide some monthly relief but little evidence that wholesale inflation pressure has faded enough to materially weaken the tightening case.
