USWC Gasoline Basis Jumps on Futures Rollover Miguel E. Andujar DTN Refined Fuels Market Reporter DAVENPORT, FL (DTN) -- California gasoline basis jumped Friday (8/21), with Los Angeles CARBOB regular climbing 35.50cts and San Francisco CARBOB regular rising 29cts as the market rolled from September to October NYMEX RBOB futures. Los Angeles CARBOB regular was heard traded at a 54cts premium to October NYMEX RBOB futures, its highest level since May 4, when it was assessed at a 56cts premium, according to DTN Energy data. San Francisco CARBOB regular was heard traded at a 50cts premium to October NYMEX RBOB futures, the strongest since June 3, when it was assessed at a 77cts premium, DTN Energy data showed. "The sharp increase is mainly related to the rollover from September to October futures," a source familiar with the West Coast gasoline market said. "With the futures curve in strong backwardation, rolling the basis against the lower-priced October contract mechanically increases the differential." The basis jump outpaced the increase in physical prices. Los Angeles CARBOB regular spot prices rose 11.53cts to $3.4432 gallon, while San Francisco CARBOB regular increased 5.06cts to $3.6135 gallon, according to DTN Energy data, supporting the view that much of Friday's basis increase reflected the futures rollover.
