   U.S. West Coast gasoline basis strengthened Friday (9/18), with California 
CARBOB reaching multi-month highs as the market rolled its benchmark to 
November NYMEX RBOB futures.

   San Francisco CARBOB Regular was heard traded at a $1.08 premium to November 
NYMEX RBOB futures, up 26cts from the previous session.

   It was also the highest differential for San Francisco CARBOB since May 5, 
2025, when it traded at a $1.20 premium to the then front NYMEX gasoline 
futures contract, DTN Energy data showed.

   Elsewhere on the West Coast, Los Angeles CARBOB Regular was assessed at a 
71cts premium to November RBOB, up 4cts from the previous session and the 
highest since November 3, 2025, when it traded at an 82cts premium.

   Portland suboctane gasoline was assessed at merchandise-level basis as the 
market rolled from October to November NYMEX RBOB futures.

   The RBOB futures curve remains in backwardation, with November trading below 
October, mechanically increasing the basis differential as the benchmark shifts 
to the lower-priced futures contract.
