Will the national average regular gasoline price fall below $3.50/gal before October 31, 2026?
The Condition
Strait of Hormuz commercial traffic returns to >50% of pre-crisis baseline for 7+ consecutive days before September 30, 2026
Our Ensemble Estimates
Given Hormuz reopens: Will the national average regular gasoline price fall below $3.50/gal before October 31, 2026?
Given Hormuz stays closed: Will the national average regular gasoline price fall below $3.50/gal before October 31, 2026?
Causal Effect
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.
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.
Resolution Criteria
EIA weekly U.S. regular conventional retail gasoline price falls below $3.50 per gallon for any weekly observation before October 31, 2026
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.
