U.S. Rack ULSD Extends Rally 16.56cts as Gasoline Slips DAVENPORT, FL (DTN) -- Wholesale rack prices for ultra-low sulfur diesel strengthened again Thursday (3/19), while conventional unleaded gasoline and premium grade gasoline eased across most U.S. regions, as refined product markets remained volatile amid continued concern over Middle East supply risk. Nationwide ULSD rack prices averaged $4.0916 gallon, up 16.56cts from Wednesday's $3.9260 gallon, according to DTN data. Conventional unleaded gasoline rack prices averaged $3.0968 gallon, down 3.83cts from Wednesday's $3.1351 gallon. Premium grade gasoline prices were mixed to lower, with declines in most regions and only marginal gains in the Rocky Mountain market. ULSD racks increased across all regions. The largest rise came in PADD 5, where prices climbed 20.37cts to $4.8040 gallon. PADD 3 rose 18.37cts to $4.1301 gallon, while PADD 2 increased 16.74cts to $3.7047 gallon. PADD 1 moved 14.92cts higher to $4.2882 gallon, and PADD 4 added 14.66cts to $4.1117 gallon. Relative to the national ULSD rack average of $4.0916 gallon, PADD 5 held the strongest premium at 71.24cts above the U.S. benchmark, followed by PADD 1 at 19.66cts above the national average. PADD 3 and PADD 4 also traded at slight premiums, while PADD 2 remained the deepest discount, at 38.69cts below the benchmark. Support for diesel values also came from broader distillate supply concerns. Europe remains reliant on imported middle distillates, leaving that market more exposed to disruptions tied to key transit routes such as the Strait of Hormuz. On conventional unleaded gasoline racks, most regions moved lower. PADD 2 posted the sharpest decline, falling 8.81cts to $2.6487 gallon. PADD 3 decreased 3.25cts to $2.8057 gallon, while PADD 1 fell 2.31cts to $2.8472 gallon. PADD 5 edged down 0.31cts to $3.8822 gallon, while PADD 4 was nearly unchanged, up 0.04cts to $3.0300 gallon. Compared with the national conventional unleaded gasoline average of $3.0968 gallon, PADD 5 remained the only region trading at a premium, at 78.54cts above the U.S. benchmark. All other regions held discounts, led by PADD 2 at 44.81cts below the national average, followed by PADD 3 at 29.11cts, PADD 1 at 24.96cts, and PADD 4 at 6.68cts below the benchmark. Premium grade gasoline rack prices were lower across most regions Thursday. PADD 1 posted the largest decline, dropping 10.53cts to $3.4704 gallon. PADD 2 fell 8.91cts to $3.2234 gallon, while PADD 3 decreased 3.27cts to $3.4570 gallon. PADD 5 moved 1.69cts lower to $4.2518 gallon, while PADD 4 was little changed, up 0.01cts to $3.4585 gallon. Premiums to conventional unleaded gasoline were widest in PADD 3 at 65.13cts, followed by PADD 1 at 62.32cts, PADD 2 at 57.47cts, PADD 4 at 42.85cts and PADD 5 at 36.96cts. In futures trading, refined products also advanced. Front-month NYMEX ULSD was at $4.4090 gallon, up 21.12cts, while front-month RBOB gasoline rose 7.56cts to $3.1741 gallon. WTI crude traded at $97.00 barrel, up 68cts, as markets continued to price in geopolitical risk and the potential for disruption to regional energy infrastructure and product flows.
