US Cash Products-Gulf Coast conventional gasoline falls on pipeline cycle change

NEW YORK, Jan 20 (Reuters) - Cash differentials for conventional gasoline blendstock fell in the U.S. Gulf Coast on Tuesday after trading rolled over to the seventh annual cycle of product deliveries to New York Harbor on the Colonial Pipeline, traders said.

Colonial Pipeline's seventh cycle will deliver products starting next month, so the price differentials will reference the March gasoline and diesel futures contracts RBc2, HOc2, which will replace the February contracts as benchmarks at that time.

On accounting for the spread between February and March contracts, U.S. Gulf Coast M4 conventional gasoline RU-DIFF-USG fell 2 cents to 3 cents below futures, market participants said. A4 CBOB gasoline CBOB-DIFF-USG rose 1.5 cents to 10.5 cents below futures, they said.

Similarly, Gulf Coast 62-grade ULSD ULSD-DIFF-USG gained 1.10 cents to 7.5 cents below futures.

In Chicago, CBOB gasoline CBOB-DIFF-MC fell half a cent to 18 cents below benchmark February gasoline futures RBc1, traders said.​ Chicago ULSD ULSD-DIFF-MC gained 1.5 cents to 31 cents below benchmark ULSD futures HOc1.

Elsewhere in the Midwest, Group 3 V-grade gasoline RUV-DIFF-G3 fell three quarters of a cent to 15.5 cents lower than the benchmark, and Group 3 diesel ULSD-DIFF-G3 fell 5.5 cents to 25 cents below the benchmark.

Benchmark gasoline futures rose 3.86 cents to settle at $1.8238 a gallon, and benchmark ULSD futures rose 10.09 cents to settle at $2.3385.

Renewable fuel (D6) credits RIN-D6-US for 2026 were unchanged at around $1.17 each, traders said. Biomass-based (D4) credits RIN-D4-US for 2026 were also the same as before at around $1.24 each, traders said.
