International oil prices hit 4-month high on additional U.S. sanctions

International oil prices rose sharply to a four-month high after additional U.S. sanctions aimed at cutting off Russia's crude exports.Brent crude futures rose to $81.49 a barrel during the day, reaching a more than four-month high, according to

Reuters.

West Texas Intermediate crude also rose to $78.39 a barrel, its highest level since October 8 last year.

Market experts said the Biden administration's announcement could double the number of tankers under sanctions, which could be a significant drag on crude oil flows.

In particular, India, which mainly imports Russian crude oil, is expected to be greatly affected.

Earlier on the 10th, the U.S. announced large-scale additional sanctions on more than 200 individuals and organizations involved in Russian oil exports and 180 oil tankers.
