Domestic inflation contained — ≤2.0%, locked at 94%.

94% probability China's consumer price index rises at or below 2.0% year-on-year in October 2026 — against 0.5% in July, in an economy where producer prices are still falling and policymakers are fighting weak demand rather than excess.

consumer price index, year-on-year · vs 0.5% in July 2026

China's consumer price index rose 0.5% year-on-year in July 2026 while the producer price index fell 3.5%, extending a 34-month factory-gate deflation streak. Commentary on the release pointed to persistent weakness in domestic demand and pressure on policymakers to support consumption and counter deflationary forces. Our ceiling sits 1.5 points above the July print. Source: China National Bureau of Statistics.

— 1 · The Locked Call

China's October 2026 CPI lands ≤2.0% year-on-year — P = 0.94.

We lock a binary: China's consumer price index for October 2026 rises at or below 2.0% year-on-year. Confidence 94%.

— 2 · Why this is the highest-confidence lock in the tranche

Consumer inflation cannot easily run hot while factory prices fall 3.5%.

China's problem in 2026 is too little inflation, not too much. Consumer prices rose 0.5% in July while producer prices fell 3.5%, and the policy conversation is about supporting consumption and countering deflation rather than restraining it. For CPI to clear 2.0% by October, consumer inflation would have to quadruple in three months while the upstream price channel is still pushing in the opposite direction. That is why this is the tranche's highest-confidence lock at 94%. It is not higher because Chinese CPI carries a large and volatile food component — pork prices in particular have historically swung the headline rate by more than a point on their own — and an adverse harvest or hog-cycle turn is the one mechanism that could deliver it. Scored on the headline national CPI year-on-year rate.
