Oil markets edged lower on Thursday after big losses in the previous session as record high oil inventories in the United States had cut short a four-day rally. Brent crude for March delivery was 14 cents lower at $54.02 a barrel by 0546 GMT, after touching $55 a barrel earlier in the day. U.S. crude stocks increased by 6.3 million barrels last week, rising for the fourth consecutive week to hit a record high of 413.06 million barrels, data from the Energy Information Administration showed.
