For the 12 months ending December, the California CPI rose 3.0%, rising from 2.6% for the year ending November. In the same period, the US CPI went to 2.9% in December from 2.7% in November.

The February average price per gallon of regular gasoline in California rose 33 cents from January to $4.77. The California regulatory and tax premium above the average for the US other than California ($3.01) rose to $1.76, a 58.6% difference.

The price rise in February once again demonstrates that California’s high fuel prices stem from its regulatory isolation from any potential relief supplies. An accident at the Martinez refinery combined with routinely scheduled biannual maintenance and the current shift to higher-cost summer formulations led to February’s increase. There are no product pipelines connecting California to the broader US market. Shipments from US supplies are limited by the number of Jones Act eligible tankers, and shipments from the few available import sources limited by distance and increasing air quality limits on tanker docking. Governor Newsom previously has indirectly acknowledged the dominant role played by California’s unique formulation regulations by twice ordering the Air Board to provide the regulatory relief that brought down consumer costs in two previous spike episodes. Instead of finally providing a real solution to the regulatory restrictions that have plagued California prices since they were first adopted in the 1990s, last year’s ABX2-1 attempts yet another partial workaround that will raise gasoline prices even further rather tackling the causes head on.
