California Gasoline Stocks Hit Record Low Due to Hormuz Disruption

• California's four-week average gasoline stocks fell to 9.44 million barrels (lowest since records began in 2005), while crude inventories dropped 23% year-over-year as refinery closures eliminated 20% of state refining capacity
• Gas prices jumped 26% since the Iran war began to $5.86/gallon statewide versus $4.09 national average, driven by the state's unique low-smog fuel blend, higher taxes, and import dependence
• State officials expect adequate supplies through mid-May from alternative sources, but analysts warn the full import shock will become visible at pumps within 1-2 weeks as Asia shipments (typically several weeks in transit) dry up

Summary

Key Developments:

California's gasoline inventories have hit record lows at 9.44 million barrels (four-week average ending April 10), the lowest since data collection began in 2005. The crisis stems from supply disruptions caused by the closure of the Strait of Hormuz, which handles one-fifth of global oil and gas supply.

Price Impact:

• California gasoline prices: $5.86/gallon (highest in U.S.)
• National average: $4.09/gallon
• 26% increase in California since the Iran war began
• Crude oil inventories down 23% year-over-year to 10.09 million barrels

Supply Vulnerabilities:

California faces unique challenges due to its isolation from national fuel pipelines and dependence on Asian imports (approximately 20% of refining capacity). The state requires a special fuel blend for smog reduction, adding to costs. Recent refinery closures representing ~20% of state capacity have increased import dependency.

Timing and Outlook:

Analysts warn the full impact hasn't materialized yet, as refined product shipping from Asia takes several weeks. Over the next 1-2 weeks, imports are expected to drop sharply. Michael Mische (USC) and Susan Bell (Rystad Energy) predict worsening conditions, though the California Energy Commission believes current stocks will last through mid-May. Daily consumption averages 36 million gallons.

Official Response:

State officials report close coordination with in-state refiners to secure alternative crude and gasoline sources, stating no near-term supply challenges are anticipated despite the volatile situation.
