Brent crude futures are up by 2.02%, trading at $42.84 a barrel, while the US West Texas Intermediate (WTI) futures are up by 2% at $40.75 a barrel.
More than 80% of crude production in the Gulf of Mexico has reportedly been stopped due to Hurricane Delta, while a strike in Norway is also affecting output capacities.
