Oil prices rebounded in Asian trade today on bargain-hunting but analysts said the fragile state of the global economic recovery continues to weigh on the market. A slew of weak economic data from the United States and Europe and signs of slowing growth in China sent prices tumbling during the week on fears energy demand will fall. New York's main contract, light sweet crude was up 57 cents to 76.31 dollars a barrel in Asian morning trade after tumbling 2.28 dollars in US trade overnight. London's Brent North Sea crude climbed 36 cents to 75.88 dollars after dropping 2.12 dollars the previous day.
