California gasoline stocks fall to record lows as Hormuz disruption bites

• California's four-week average gasoline stocks hit 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
• Pump prices reached $5.86 per gallon statewide, a 26% increase since the Iran war began and 43% above the national average of $4.09
• Import shock expected to fully materialize in 1-2 weeks as shipping from Asia takes several weeks, though state officials believe current stocks will prevent shortages through mid-May

California Gasoline Stocks Hit Record Lows Amid Strait of Hormuz Disruption

Key Developments:

California's gasoline inventories have plummeted to historic lows, averaging 9.44 million barrels for the four weeks ending April 10—the lowest level since data collection began in 2005. The crisis stems from the closure of the Strait of Hormuz, which transports one-fifth of global oil and gas supply.

Price Impact:

As of April 16, 2026, California motorists are paying $5.86 per gallon—the highest in the U.S. and far above the $4.09 national average. This represents a 26% increase since the Iran war began. Prices are elevated due to state taxes and California's unique low-smog gasoline blend requirements.

Supply Vulnerabilities:

California is particularly exposed to supply shocks due to its isolation from national fuel pipelines and heavy reliance on refined products from Asia, where refiners use Middle Eastern crude. Refinery closures accounting for approximately 20% of state capacity have increased import dependency. Crude oil inventories are down over 23% year-over-year to 10.09 million barrels.

Timing Concerns:

Analysts warn the full impact has yet to materialize. Shipping from Asia typically takes several weeks, with import disruptions expected to sharply intensify over the next one to two weeks. California consumes approximately 36 million gallons daily.

Official Response:

The California Energy Commission states it's coordinating with in-state refiners and sourcing alternative imports. Officials expect adequate inventory through mid-May and do not anticipate near-term shortages, though independent analysts like USC's Michael Mische and Rystad Energy's Susan Bell project worsening conditions ahead.
