Crude prices declined Monday as an OPEC official hinted to boost output.

    Algerian Oil Minister Chakib Khelil, who is to take over as president of the Organization of Petroleum Exporting Countries on Jan. 1, said the cartel would not exclude the possibility of increasing production.

    Data released by oil tanker-tracker Petrologistics shows OPEC oil exports have already risen by about 400,000 barrels a day.

    Light sweet crude for January delivery fell 64 cents to settle at 90.63 dollars a barrel on the New York Mercantile Exchange.

    In London, Brent crude fell 40 cents to settle at 91.29 dollars a barrel on the ICE Futures exchange.
