Oil Price Today (May 21): Crude oil rises slightly after two days of fall as Iran-US issue fresh threats. What lies ahead?

Oil prices saw marginal gains as fresh threats between Iran and the US heightened concerns over the Strait of Hormuz closure. While Iran examines a new US proposal, President Trump indicated talks are on the "borderline" between a deal and renewed strikes. The ongoing blockade of the vital waterway continues to keep oil prices above $100 per barrel.
