Chicago gasoline prices climbed higher today even as fresh data revealed US midcontinent CBOB stockpiles have grown to near record-high levels.
West Shore/Badger pipeline CBOB prices notched the narrowest discount to the March Nymex RBOB contract in 10 trading days, as prices rose to 16.75¢/USG below the Nymex today on February's first trading cycle. CBOB prices at the Wolverine Pipeline and Buckeye Complex rose higher to 12.5¢/USG discounts to the Nymex, the slimmest spreads in 11 and three sessions, respectively.
Prices increased despite bearish inventory data showing US midcontinent CBOB inventories reached 38.9mn bl last week, up by 0.8pc to the highest since February 2019, according to US Energy Information Administration (EIA) estimates. This was just 4.2pc below the highest level on EIA record, set when stockpiles climbed to 40.7mn bl the first week of February 2019. The EIA has tracked midcontinent CBOB levels since April 2004.
Total gasoline stocks in the midcontinent rose by 1.6pc to 57.5mn bl last week, the most since April 2020.
With prices fetching smaller discounts to the Nymex, outright prices to purchase CBOB reached 12-week highs across the Chicago region.
Arbitrage economics for shipping US Gulf coast CBOB to the Buckeye Complex at Hammond, Indiana, remained unviable on paper with Buckeye Complex CBOB holding a 6.875¢/USG discount to the Gulf coast.
Elsewhere in the midcontinent, CBOB prices at the Magellan Pipeline in Tulsa, Oklahoma, widened their discount to the Nymex to 7.5¢/USG after cutting that spread by a combined 1.5¢/USG the prior four trading days.
