Oil rose for a third day in New York as Libyan output fell and on speculation that the U.S. Federal Reserve will maintain the pace of stimulus. Brent oil headed for the biggest gain in more than two weeks.

West Texas Intermediate advanced as much as 1 percent after state-run National Oil Corp. said crude production in Libya, holder of Africa’s largest reserves, declined to about 250,000 barrels a day because of labor protests.

Brent rose as much as 2.2 percent.
