Saturday's drone attacks on Saudi oil infrastructure may not be a "game-changer" for the tanker sector since return to normal output is expected soon, a prominent analyst says.

Key processing units in Quibab and Khurais were disabled, threatening to take 5.7mn barrels per day — or 5% of global output — off the market.

Saudi Arabia calmed supply-demand fears Tuesday, however, by saying 70% of lost output would be restored in days with inventories filling the gap, Evercore's Jon Chappell said.
