Oil prices sank five percent on Tuesday, reversing some of the previous day’s gains as analysts predicted Saudi output would recover sooner than expected after weekend drone attacks. In the space of several minutes in afternoon European trading, North Sea Brent crude oil for delivery in November tumbled from $67.75 to $65.00. “The markets were once again wrong-footed by the Saudi news,” said Forex.com analyst Fawad Razaqzada in reaction to Tuesday’s price drop.
