Japan's December CPI Plunges to 1.5% Falling Below Central Bank Target; Energy Subsidies Suppress Inflation Expectations

2026-02-20

According to the latest DataTrack data, Japan's December Consumer Price Index (CPI) year-on-year growth rate plummeted to 1.5%, showing a significant decline from 2.1% in November and remaining far below the peak seen at the end of 2024. This figure not only sets a new low since 2022 but also fell below the 2% inflation target long upheld by the Bank of Japan (BOJ) in one fell swoop, indicating that under the dual influence of base effects and policy intervention, Japan's inflation pressure has rapidly cooled.

Observing the detailed components, the key to this significant CPI retreat lies in the materializing effects of the government's subsidy policy for public utilities. According to market information, electricity and gas prices turned from rising to falling after subsidies were reinstated, directly pulling down the overall price level. Meanwhile, food prices (especially rice prices), previously a main driver of inflation, showed signs of peaking and retreating; gains in core items excluding fresh food also slowed simultaneously, showing that the momentum of cost-push inflation is weakening.

Regarding this sharp drop in data, market institutions such as Credit Agricole and NLI Research Institute analyzed that the government's fiscal measures aimed at lowering the cost of living are the main cause of the "artificial" decline in inflation figures. Analysts warn that although the headline figure dropped to 1.5%, this masks the fact that service sector inflation remains sticky. However, overall weak domestic demand has reduced companies' willingness to pass on costs, which will present the BOJ with a more complex decision-making environment when pushing for monetary policy normalization.

Looking ahead, in the short term (1-2 months), due to the continued influence of subsidy policies, the CPI year-on-year growth rate is likely to consolidate at a low level around 1.5%, and the risk of further decline cannot be ruled out. In the medium term (3-6 months), the focus will shift to the results of the Spring 2026 wage negotiations (Shunto). If wage growth cannot offset the price rebound after subsidies exit or support real purchasing power, the Japanese economy may face the risk of a resurgence of a "deflationary mindset," forcing the BOJ to pause its interest rate hike pace.
