WTI Midland eased 35 cents, while WTI at East Houston weakened 25 cents. Light Louisiana Sweet weakened 40 cents. Mars, however, gained 5 cents.
The U.S. 3:2:1 crack spread, a proxy measure for refining margins, weakened to as low as $29.07, its lowest in a month, worrying markets that refineries may buy and process lower amounts of crude ahead of the summer driving season. On the supply side, Russian crude also continued to find its way into the markets, with oil loading from Russia's western ports in April likely to rise to the highest since 2019.
Pakistan has also placed its first order for discounted Russian crude under a new deal which could cover 100,000 barrels per day (bpd). West Texas Intermediate crude's discount to Brent narrowed further to its smallest since late December. In refining news, the small coker at Motiva Enterprises 626,000 bpd Port Arthur, Texas refinery may be shut for two weeks after the unit's restart was stopped by a malfunction, two people familiar with plant operations said on Thursday.
