Japan's Producer Prices Rise 2.3% in January, Pace Moderates Slightly

Overview of January's Producer Price Index

Japan's producer price index (PPI) saw a year-on-year increase of 2.3% in January 2026, according to data released by the Bank of Japan (BOJ) on Thursday, February 12, 2026. This figure, which matched market expectations, represents a slight moderation from the 2.4% rise recorded in December. The index, also known as the Corporate Goods Price Index (CGPI), stood at 128.4 against a 2020 average of 100, extending its upward trajectory for the 59th consecutive month.

Key Drivers and Sectoral Breakdown

The overall increase in producer prices was influenced by divergent trends across various sectors. Significant upward pressure came from:

• Nonferrous metals, which surged by 33%, primarily due to soaring copper prices.
• Agricultural products, experiencing a 22.4% jump, driven by higher prices for rice and salmon. A BOJ official noted that 'Rice prices have largely stabilized' after previous sharp increases.
• Food and beverages, which saw prices grow by 4.7%, as manufacturers continued to pass on increased costs to consumers.

Conversely, some categories experienced price declines or slower growth:

• Petroleum and coal products fell by 12.9%, a faster decline than the 8.3% drop in December, attributed to lower crude oil prices.
• Prices for chemicals decreased by 3.2%, and iron and steel saw a 5.5% decline.

Monthly Trends and Import Costs

On a month-on-month basis, Japan's producer prices rose by 0.2% in January, an increase from the 0.1% recorded in December. The report also highlighted that yen-based import prices increased by 0.5% year-on-year, up from a 0.2% gain in December. This indicates that a weaker yen continues to contribute to cost pressures for imported raw materials and energy, even as global commodity prices show signs of stabilization.

Context and Outlook

The 2.3% annual rise in January marks the slowest pace of increase since May 2024. While the moderation suggests a gradual cooling of producer-level price momentum, the persistent rise in import costs due to currency weakness presents a complex picture for policymakers. The Bank of Japan continues to assess underlying price growth as it navigates its monetary policy decisions.
