WTI for January delivery fell 11 cents to $58.91 a barrel on the New York Mercantile Exchange as of 8:43 a.m. local time. The contract closed 18 cents lower on Monday after jumping 7.3% last week.

Brent for February settlement declined 10 cents to $64.15 a barrel on the London-based ICE Futures Europe Exchange after slipping 0.2% on Monday. The global benchmark crude traded at a $5.31 premium to WTI for the same month.
