Midwest Jet Fuel Discounts Stay Diverged on Supply Shift Barani Krishnan DTN Refined Fuels Market Reporter SECAUCUS, NJ (DTN) -- The discount for Midwest jet fuel variants against NYMEX ultra-low sulfur diesel (ULSD) for July remained in divergence on Tuesday (6/9) as regional supply pressures shifted. Market participants noted that Chicago differentials weakened by 10cts while Group 3 basis barrels strengthened by 10cts. Chicago jet fuel was talked at a discount of 80cts to NYMEX ULSD for July, expanding from Monday's assessment of 70cts. Meanwhile, the basis for Group 3 jet fuel was heard at a narrower discount of 75cts a gallon to July ULSD, recovering from Monday's 85cts. Pipeline scheduling windows across the Magellan and Badger systems continue to aggressively drive spot market valuations for Midcontinent product. Shippers unable to secure immediate line space are forced to heavily discount local barrels to find instant buyers or open storage. Unlike the Chicago market, which relies on nearby Great Lakes distribution networks, Group 3 pricing is uniquely captive to the sprawling Magellan system, making its basis highly sensitive to pipeline scheduling bottlenecks and Oklahoma storage capacity. The vulnerability to regional gluts is magnified during peak refinery runs because the Midwest lacks the structural aviation demand deficit that supports East Coast prices. Reflecting supply pressures, Energy Information Administration data showed Midwest jet fuel inventories building by 800,000 bbl weekly and 500,000 bbl annually to reach 6.8 million bbl during the week ended May 29.
