As prices jumped to another record, a member of OPEC signaled on Friday for the first time in months that the oil cartel might increase its output to prick the price bubble.

The comments, from Libya’s senior oil official, Shokri Ghanem, suggested a possible shift in OPEC’s position. Since the cartel’s last meeting in March, OPEC has argued that the market was not lacking in oil supplies and blamed speculators for driving up prices.

But in recent weeks, prices have come under renewed pressure because of a string of export disruptions from Nigeria. Prices have been above $100 since early February. Crude oil for June delivery closed up $2.27, at $125.96 a barrel in New York on Friday, after rising as high as $126.25 during the day.

Since OPEC last increased oil supplies in September, members of the Organization of the Petroleum Exporting Countries have argued that the higher prices had more to do with investment flows than with supply and demand.
