Oil jumped as rising tension in the Middle East and North Africa halted output and exports from key OPEC producers Iraq and Libya.

Futures in New York and London rose more than 1.5%. Iraq temporarily stopped output at an oil field on Sunday and supply from a second site is at risk as widespread unrest escalates in OPEC’s second-biggest producer. In Libya, National Oil Corp. declared force majeure after Commander Khalifa Haftar blocked exports at ports under his control.

West Texas Intermediate for February delivery climbed as much as $1.19, or 2%, to $59.73 a barrel on the New York Mercantile Exchange and traded at $59.23 as of 8:37 a.m. Singapore time. The contract fell 0.9% last week.

Brent for March settlement added as much as $1.15, or 1.8%, to $66 a barrel on the London-based ICE Futures Europe Exchange. The global benchmark crude traded at a $6.29 premium to WTI for the same month.
