Oil rose on Monday, hitting a three-week high, supported by strong U.S. demand and comments from Saudi Arabia that it would continue to curb production in line with OPEC-led efforts.
U.S. West Texas Intermediate crude ended Monday's session up 36 cents at $63.91 a barrel, its best closing level in three weeks.
Brent crude rose 17 cents to $67.48 a barrel at 2:29 p.m. ET, after hitting an intraday high going back to Feb. 2.
Prices were supported by Saudi Energy Minister Khalid al-Falih, who said on Saturday the country's crude production in January-March would be well below output caps, with exports averaging less than 7 million barrels per day.
