LONDON (Reuters) -Oil prices rose on Thursday, recovering slightly from a multi-year low, though Brent was still below $70 under pressure from trade tariffs between the United States, Canada, Mexico and China and OPEC+ plans to raise output. Those factors and a larger than expected build in U.S. crude inventories had sent Brent as low as $68.33 on Wednesday, its weakest since December 2021. Brent futures were up 53 cents, or 0.8%, at $69.83 a barrel by 1246 GMT on Thursday while U.S. West Texas Intermediate crude futures gained 54 cents, also 0.8%, to $66.85.
