Crude declined for the first time in a four-day period on Thursday as stockpiles in the U.S. reached the 22-year high and as the International Energy Agency's outlook for global oil demand decreased. May Brent futures lost 70 cents, or 0.7%, to $105.09 a barrel on London's ICE Futures Europe exchange, while the Brent premium to WTI fell to $10.75, the narrowest since June 2012.
