How are Russian refinery disruptions tightening the global diesel market?
Sustained attacks on Russian refining infrastructure are reshaping middle distillate balances. Russian refining runs have been revised down toward 4 million b/d for the remainder of 2026 and into 2027. Combined Middle East and Russian diesel exports fell to roughly 520,000 b/d in August, down about 75% year on year, with higher US and Asian volumes only partly filling the gap. Global seaborne gasoline and diesel exports averaged 4.7 million b/d in the first eight months, down 10%. The squeeze pushed US diesel crack spreads above USD 100/bbl in September, with inventories at multi-decade lows. Q4 seasonal demand could widen cracks further.
