A 300,000 barrel-per-day drop in Canadian oil sands output threatens US refining margins amid already tight fuel supply.
US refiners face a fresh crude supply squeeze as Canadian oil sands maintenance slashes output by 300,000 barrels per day in September. The reduction comes as US plants operate at full capacity to offset Middle East fuel shortages and export record volumes, leaving little room to absorb the disruption.
Typically, seasonal maintenance disruptions are mitigated by drawing from storage, but inventories remain tight after months of elevated refining runs. Analysts warn the shortfall could pressure refining margins, particularly for Midwest plants reliant on Canadian heavy crude.
No immediate market reaction was reported, though traders are monitoring the potential impact on crude differentials and refining spreads.
