Conditions of places like Venezuela, Iran, and Africa might lead to supply disruptions. The distress of the tight market, as a result, led oil prices to climb up on Tuesday. The effect on Brent crude futures was such that it increased by 0.4%, at $76.51 per barrel while WTI also rose by 0.4% and was traded at $69.11 a barrel. Crude supply is restricted due to restrained output by OPEC.
