Oil prices increased on Monday as fears of limited global supply intensified, with the developing crisis in Ukraine raising the risk of more penalties from the West against Russia, the world’s leading exporter.

Brent futures were up $1.50, or 1.3 per cent, at $113.20 a barrel, while US West Texas Intermediate futures were up 98 cents, or 0.9 per cent, at $107.93 per barrel. Both contracts surged more than 2.5 per cent on April 14, ahead of the Easter weekend holidays, on news that the European Union would phase in a ban on Russian oil imports.

Last week, EU governments said that the bloc’s executive was working on ideas to ban Russian oil, but officials said Germany was not actively backing an immediate ban.
