Causal Effect

+41pp(positive)

Hormuz reopening worth ~41pp to gasoline below $3.50 probability (47% if reopens vs 6% if closed). The sharpest causal effect — gasoline at $3.99 is mechanically tied to crude prices. Under continued closure, sub-$3.50 is near-impossible. Even with reopening, rockets-and-feathers lag and summer driving create uncertainty.

Unconditional probability:20.3%(blended: P(Y|T) × 35.0% + P(Y|F) × 65.0%)

Why This Matters

Tests the consumer relief timeline if Hormuz reopens. Gasoline at $3.99 is at the $4.00 political threshold, with implied prices at current Brent levels suggesting $4.10-4.30. If Hormuz traffic resumes above 50% of baseline, crude prices should decline as the supply disruption premium ($22-25/bbl) and tail risk premium ($18-21/bbl) compress. However, gasoline price transmission has asymmetric dynamics: prices rise faster than they fall ('rockets and feathers' effect). Refining margins may remain elevated due to months of inventory drawdowns and refinery operational disruptions. The $3.50 threshold requires not just a crude price decline but also normalization of refining margins and distribution logistics. Seasonal summer driving demand (June-August) creates additional upward pressure on gasoline even as crude declines. The SPR at 243M barrels limits the government's ability to accelerate the gasoline price decline.

Condition Resolved

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

Source Analysis

Offset capacity remains INSUFFICIENT with declining trajectory. Iran sanctions waiver expires April 19 with no extension. SPR depleting below 243M barrels. Maximum deliverable non-Hormuz barrels is 200-250K bpd (Petroline at 44% of 5.0 mbpd nameplate). Total effective offsets declined from 5.0-6.5 to 4.9-6.5 mbpd. Gasoline at $3.99 approaching $4.00 political threshold.
