Brent crude oil futures dipped 4 cents, to 49.09 dollars per barrel, today, with some support from new Chinese reserve regulations, but remained on track for a seventh monthly fall, as prices were weighed down by a global supply glut. Brent is on track to post a 14 percent fall in January, marking a seventh month of declines. US crude was up 25 cents, at 44.78 dollars a barrel. Data this week showed US crude oil inventories had reached their highest levels since the 1930s. The market found some support from China, where new commercial crude reserves regulations are likely to boost import demand in the short term. The weakened Russian Rouble currency, which has lost 50 percent of its value against the dollar in the past six months, is having a particularly strong impact on oil markets. The International Energy Agency had earlier said a price rebound could take some time.
