Heating oil futures rose above $4.70 per gallon, nearing the mid-September record of $5.20, as Russia extended restrictions on most diesel exports through October. The curbs, introduced after Ukrainian attacks reduced Russian refinery processing rates and repeatedly prolonged since July, are adding pressure to fuel markets alongside disruptions linked to the Strait of Hormuz. Russia previously supplied about 10% of global seaborne diesel volumes. In the United States, President Donald Trump is considering limiting diesel exports to contain domestic prices.
