LONDON, Jan 20 (Reuters) - Oil futures fell further on Wednesday, with U.S. crude touching its lowest since 2003, as a global supply glut bumped up against bearish financial news that sparked deeper worries over demand.
U.S. crude oil CLc1 dropped more than 4 percent in early trading, falling to as far as $27.32 a barrel. It bounced back to trade down 70 cents at $27.76 as of 0945 GMT.
The contract settled down 96 cents, or 3.26 percent, in the previous session.
"You need the low price to slow down shale much faster," said Bjarne Schieldrop, chief commodities analyst with SEB in Oslo. He added that a "very broad-based sell-off across assets and across the world" would amplify pressure on oil prices.
"With oil being fundamentally weak, it should be moving down even further."
Brent futures LCOc1 fell by 75 cents to $28.01 a barrel, after trading as low as $27.77, not far from the 12-year trough of $27.67 hit on Monday. They settled up 21 cents, or 0.7 percent, in the previous session.
Asian equities hit four-year lows during the day's trading, partly as oil itself curbed investor appetite for risky assets. European stocks also opened under downward pressure. MKTS/GLOB
