Will Japan's core CPI increase by less than or equal to 1.9% in 2026?

The question asks whether Japan's core CPI (all items less fresh food) will increase by ≤1.9% in 2026, based on the annual average change from 2025 to 2026. The most recent data points show core CPI at 1.8% in July 2025 Reuters JapanFT articleReuters Japan, up from 1.6% in June Reuters JapanReuters Japan, and Tokyo core CPI at 1.9% in July Reuters Annual. These figures are already at or near the 1.9% threshold, suggesting that if current trends continue, the 2026 annual average could be around or slightly above 1.9%. However, the resolution is for the 2026 annual average, which is a full-year figure that will be influenced by monthly data throughout 2026, not just the current trajectory. The Bank of Japan is considering rate hikes Reuters JapanFT article, which could dampen inflation, but rising import costs from a weak yen and geopolitical tensions (e.g., Middle East conflict) are pushing prices up Reuters JapanReuters Annual. Analysts expect inflation to accelerate later in 2025 due to higher producer prices Reuters Japan, which could carry into 2026. Given that current monthly rates are already at 1.8-1.9%, and the trend is upward, there is a meaningful chance that the 2026 annual average exceeds 1.9%, but it is not certain because the BOJ's tightening and potential base effects could keep it at or below that level. The evidence is mixed: the recent acceleration suggests a >50% chance of exceeding 1.9%, but the threshold is close to current levels, and policy responses could cap it. I assign a 60% probability to the YES outcome (≤1.9%), as the current data and forecasts do not strongly indicate a sustained breakout above 1.9% for the entire 2026 year, but the risk is tilted toward higher inflation.
