Oil prices eased slightly on Tuesday as markets braced for uncertainties from the US presidential election:il prices eased slightly on Tuesday as markets braced for uncertainties from the US presidential election, after rising more than 2% in the past session as OPEC+ delayed plans to hike production in December and eased supply concerns. Brent crude futures fell 15 cents, or 0.2%, to $74.93 a barrel while US West Texas Intermediate crude was at $71.33 a barrel, down 14 cents, or 0.2%. According to Qatar News Agency, Oil prices were supported by Sunday's announcement from the Organization of the Petroleum Exporting Countries and their allies, a group known as OPEC+, to push back a production hike by a month from December as weak demand and rising non-OPEC supply depress markets.
