Will China's NDRC issue a formal anti-involution policy targeting petrochemical capacity rationalization by 2026-12-31?

Resolution criteria is permissive: NDRC or joint NDRC-MIIT, with quantitative targets OR enforcement mechanisms. Xi anti-involution theme has produced formal documents in solar (2024 MIIT) and EVs (2025 joint NDRC-MIIT), so chemical sector follows plausibly. However: (1) Chinese state-owned operators (Sinopec, PetroChina) are primary and resist capacity cuts that threaten employment/stability, (2) formal documents tend to use qualitative language (high-quality development) rather than quantitative capacity cuts, (3) year-end 2026 is ~8 months from analysis date — relatively tight. Probability 40-50%. Settle 0.45 reflecting genuine uncertainty between formal-policy momentum and Chinese regulatory tradition of opacity.

Historical Chinese policy tradition for cyclical industries: formal quantitative capacity-cut targets are published but often as 'capacity replacement' (removing inefficient for efficient) rather than pure reduction. The resolution requires 'rationalization/anti-involution' explicitly — qualifying documents may come but with different language framing. Committee's expected Q2 2026 timing suggests some signaling basis, but expectations ≠ publication. Year-end 2026 gives time for delayed publication. 0.42 reflects modest uncertainty.

Slightly more optimistic: the momentum of Xi anti-involution theme through 2025 has produced multi-sector guidance that typically crystallizes into formal documents within 6-12 months. Solar precedent (2024) and EV precedent (2025) show the pattern. Committee's Q2 expectation suggests insider sentiment is aligned. Permissive resolution criteria (joint NDRC-MIIT documents with enforcement mechanisms) captures a broader policy form set. Probability 45-50%. Settle 0.48.

Chinese industrial policy for large employer sectors (chemicals is a major employer) tends to emerge as multi-ministry guidance rather than clean NDRC documents. Formal quantitative targets are rarer. 40% captures the balance between active Xi theme and publication-form uncertainty.

Modeling: P(formal policy published by year-end 2026) ~55-60%. P(document explicitly names petrochemical | published) ~75-80% (chemicals is a clear overcapacity sector). P(quantitative targets or enforcement | published and names chemicals) ~70%. Joint ~0.55 * 0.78 * 0.70 = 0.30. Adjust up for permissive criteria (MIIT joint, enforcement 'or' quantitative). Settle 0.45.

Committee load-bearing assumption but committee cannot force reality. Chinese policy publication cadence is uncertain; year-end 2026 is tight. 0.43 reflects meaningful probability but not base case.

Xi anti-involution theme + solar/EV precedents + committee expectation Q2 2026 = meaningful probability of formal document. Year-end horizon is adequate but not comfortable. 0.43 central.

Base rate for multi-sector policy crystallization in target year is 40-50% given signaling basis. Settle 0.45.

Chinese publication uncertainty + SOE resistance arguments pull below 50%. 40% captures the downside scenarios. Settle 0.40.
