Given that oil demand growth next year probably won't be much more than 1 million barrels a day, a full unwinding of OPEC+ supply cuts in 2025 would "undoubtedly see a very steep slide in crude prices, possibly toward $40 a barrel," Henning Gloystein, head of energy, climate and resources at Eurasia Group, told CNBC.

OPEC’s recent decision to extend its production cuts till the end of January has added more uncertainty to the oil market as we approach 2025.

Oil prices on the New York fuel exchange are slightly rising, but they remain close to this month's lowest levels. Brokers say investors are focused on the fuel demand outlook after OPEC countries lowered their oil demand growth forecasts for this and next year.
