World oil prices eased but remained above 125 dollars on Monday after an inflow of investment funds and supply worries helped push costs to another record high, analysts said. New York's main oil futures contract, light sweet crude for June delivery, was 56 cents lower at 125.40 dollars a barrel. The benchmark contract closed on Friday at 125.96 dollars after spiking to a record 126.25 dollars in intraday trading at the New York Mercantile Exchange. Brent North Sea crude for June was 61 cents lower at 124.79 dollars a barrel after briefly hitting an all-time peak of 125.90 dollars in London on Friday before settling at 125.40 dollars.
