Brent crude futures extended their four-month winning streak, approaching $118 a barrel and reaching their highest level in six months as traders assessed the risk that U.S. strikes on Iran could resume after next week's midterm elections. West Texas Intermediate closed above $104. Prices were supported by concerns over supply disruptions, low inventories, repeated tanker attacks and tight refined-product supplies, although oil shipments through the Strait of Hormuz are recovering. The U.S. administration signed contracts on October 30 for about 41 million barrels from the Strategic Petroleum Reserve, but the market remained focused on the possibility of a broader conflict. Brent and WTI later pared gains after President Donald Trump said peace talks were under way and that there was time. ANZ strategists said the prospect of renewed fighting after the vote was adding uncertainty to an already fragile physical crude market.
