SINGAPORE – Oil prices slid on Tuesday from their highest levels in a month on a stronger dollar and after the head of the International Monetary Fund warned of a tougher 2023 as major economies experience weakening activity.

Brent crude futures dropped 98 cents, or 1.1 percent, to $84.93 a barrel by 0148 GMT while US West Texas Intermediate crude was at $79.49 a barrel, down 77 cents, or 1.0 percent, after the US dollar strengthened. A stronger greenback makes dollar-denominated commodities more expensive for holders of other currencies.

IMF Managing Director Kristalina Georgieva said on Sunday that the United States and Europe – the main engines of global growth – are all slowing down simultaneously, making 2023 tougher than 2022 for the global economy.

Still, oil prices settled more than 2 percent higher on Friday with Brent and WTI closing 2022 up 10.5 percent and 6.7 percent, respectively.
