The price of oil rose above $87 a barrel Monday, Nov 19, in Asia as the conflict between Israel and Hamas showed no signs of abating, raising concerns about crude supplies, The Associated Press reported.

Benchmark oil for December delivery was up 81 cents to $87.73 per barrel at midday Bangkok time in electronic trading on the New York Mercantile Exchange. The contract added $1.05 to finish at $86.92 per barrel on Friday.

Brent crude, used to price many international varieties of oil, rose 55 cents to $109.50. It closed Friday at $108.95 per barrel in London.

Gordon Kwan, head of energy research at Mirae Asset Securities Ltd. in Hong Kong, said some investors fear that oil supplies could be disrupted if the Israel-Hamas conflict engulfs countries elsewhere in the Middle East, a huge producer of crude.

The "market is putting a geopolitical premium on the price of oil amid escalating tensions between Israel and Palestine and that could continue for some time," Kwan said.
