The Condition

Strait of Hormuz sustained disruption (>50% traffic reduction for 14+ days) before June 30, 2026

External probability: 100.0%Source: Polymarket Iran Conflict MarketsResolves: June 30, 2026

Our Ensemble Estimates

If condition is true
82%
Model agreement: 87%

Given Hormuz sustained disruption: Will headline CPI YoY exceed 4.0% by June 2026?

If condition is false
32%
Model agreement: 83%

Given Hormuz reopens: Will headline CPI YoY exceed 4.0% by June 2026?

Causal Effect

+50pp(higher)

Sustained Hormuz disruption increases the probability of headline CPI exceeding 4.0% by +50pp (82% vs 32%), up from +47pp. The widening reflects ACCELERATING classification and gasoline pass-through making the IF TRUE case nearly mechanical while IF FALSE rose more modestly on non-oil channels.

Unconditional probability:75.5%(blended: P(Y|T) × 100.0% + P(Y|F) × 0.0%)

Why This Matters

Tests whether sustained Hormuz disruption pushes headline inflation past the 4.0% threshold through compounding energy price pass-through.

Condition Resolved

The condition was TRUE. The IF TRUE branch is now the active prediction.

Source Analysis

Inflation is driven by compounding supply-side pressures across three simultaneous channels: energy supply shock, tariff cost-push, and natural gas surge; pre-shock core PCE already sticky at 2.8-3.0% and re-accelerating
