Sanctions against the two countries are expected to further support prices, reports Reuters.

Meanwhile, investors are awaiting today’s meeting of eurozone finance ministers to approve the region’s €440bn bailout fund.

US crude fell by 12¢ to $98.09 a barrel following Fitch Ratings’ revision of the US credit rating outlook to negative, and an expected rise of one million barrels in domestic crude stocks.
