The International Energy Agency (IEA) now expects oil demand to grow by 1.24 million barrels per day (bpd) in 2024, up 180,000 bpd from its previous projection, its monthly report said. The agency cited improved economic growth and lower crude prices in the fourth quarter.

The Organization of the Petroleum Producing Countries (OPEC) had said on Wednesday that it expected demand growth of 2.25 million bpd this year, unchanged from its forecast in December. The producer group also said oil demand is expected to rise by a robust 1.85 million bpd in 2025 to 106.21 million bpd.

The IEA's executive director, Fatih Birol, told the Reuters Global Markets Forum on Wednesday that he expects oil markets to be in a "comfortable and balanced position" this year despite Middle East tensions, rising supply and a slowing demand growth outlook.
