Oil prices rose on Monday to end January with their biggest monthly gain in a year, boosted by a supply shortage and political tensions in Eastern Europe and the Middle East.

U.S. West Texas Intermediate crude rose $1.33, or 1.5%, to close at $88.15 a barrel.

The benchmarks recorded their highest levels since October 2014 on Friday, at $91.70 and $88.84, respectively, and their sixth straight weekly gain. They gained by about 17% this month, the most since February 2021.
