NEW YORK (CNBC) - Oil prices rose to their highest in more than week on Monday after two large crude production bases in Libya began shutting down amid a military blockade, risking reducing crude flows from the OPEC member to a trickle.
Brent crude was up 37 cents, or 0.6%, at $65.22 by 0952 GMT, having earlier touched $66 a barrel, the highest since Jan. 9.
The West Texas Intermediate contract was 24 cents, or 0.4%, higher at $58.78 a barrel, after rising to $59.73, the highest since Jan. 10.
Two major oilfields in southwest Libya began shutting down on Sunday after forces loyal to Khalifa Haftar closed a pipeline, potentially cutting national output to a fraction of its normal level, the National Oil Corporation (NOC) said.
The closure, which follows a blockade of major eastern oil ports, risked taking almost all the country’s oil output offline
However, the earlier rise in oil prices eased after some analysts and traders said supply disruptions in Libya could be offset by other producers, limiting the impact on global markets.
"The oil market remains well supplied with ample stocks and a healthy spare capacity cushion. In other words, the bullish price impact may prove to be fleeting,” said Stephen Brennock of oil broker PVM.
Takashi Tsukioka, president of the Petroleum Association of Japan (PAJ), also told a news conference that oil prices may fluctuate due to the latest incidents, but "we don’t have to worry too much about demand and supply balance as OPEC can cover shortfalls.”
If Libyan exports are halted for any sustained period, storage tanks will fill within days and production will slow to 72,000 barrels per day (bpd), an NOC spokesman said. Libya has been producing around 1.2 million bpd recently.
