REUTERS SURVEY: Middle East spot crude has firmed on supply interruptions, and Saudi Arabia is likely to raise November official selling prices (OSP) to Asia buyers. Four refinery sources said flagship Arab Light's November OSP could be up to $3/bbl above the Oman/Dubai average and roughly $5/bbl higher than October; one source expected OSP to be unchanged. Traders cite elevated Middle East supply risk after U.S.-Iran tensions pushed Dubai and Oman spot premiums in September to their highest since late March. Although flows through the Strait of Hormuz have partly recovered, spot spreads remain noticeably above August levels.
