Brent crude oil futures slipped towards 109 dollars a barrel, today, after the U.S. Federal Reserve's latest policy statement was less dovish than some had expected, prompting fears an easy money regime that had supported commodities may soon end. But Brent was still set to end October with its fourth monthly gain in five as disruptions to shipments from major producer Libya kept supply tight. Brent crude for December delivery fell 26 cents, to 109.62 dollars a barrel. Brent was on track for a 1.1 percent gain in October. US crude rose 4 cents, at 96.81 dollars a barrel, but the U.S. benchmark was on course for a fall of over 5 percent for October, its worst month since February, as stockpiles increased in the world's top oil consumer.
