Oil prices held near multi-year highs on Monday, underpinned by an improved outlook for demand as increased COVID-19 vaccinations help lift travel curbs. West Texas Intermediate was also up 14 cents, or 0.2%, at $71.05 a barrel, after reaching the highest since October 2018 at $71.24 on Friday and rising 1.9% on the week. The Organization of the Petroleum Exporting Countries (OPEC) and allies, known as OPEC+, need to increase output to meet recovering demand, the International Energy Agency (IEA) said in its monthly report on Friday.
