US heating oil prices fell below $4.90 per gallon, their lowest level in two weeks, as expectations for improved supply and progress in diplomatic talks reduced immediate supply concerns. Saudi Arabia restarted its East-West oil pipeline at a reduced rate after a drone-related shutdown, with Yanbu exports expected to resume, although restoring full flows could take six to eight weeks while repairs continue. Iran said it could reopen the Strait of Hormuz within a week if the US eases military pressure and lifts its blockade, while President Trump described a meeting between US and Iranian officials as "very productive." Near-term risks remain: winter heating demand could increase, refinery maintenance may limit distillate production, and Russia is set to extend diesel export restrictions through October. Industry data showed distillate inventories fell by 2.2 million barrels in the week ended September 18.
