US Cash Crude-Grades largely down on weakened refinery demand

June 20 (Reuters) - Physical U.S. crude grades broadly fell on Thursday amid lower domestic refinery utilization, dealers said. Thursday marked WTI futures’ expiry, signaling the beginning of the volatile roll trading period. Traders use the three-day roll period to square positions and manage exposure, resulting in more volatile trading. HF Sinclair’s (DINO.N) 162,000-barrel-per-day (bpd) refinery in El Dorado, Kansas is running at lower rates due to repairs, sources familiar with the matter said, weighing on crude demand. U.S. crude oil inventories fell last week as exports rose, the Energy Information Administration said. But refinery crude runs fell by 282,000 barrels per day (bpd) in the week, and refinery utilization rates fell by 1.5 percentage points to 93.5% of total capacity. Meanwhile, U.S. crude imports of Canadian crude reached a six-month high last week, at 4.137 million barrels, the EIA said.
