Oil Edges Higher on Geopolitical Tensions

Oil prices fell for a second consecutive day Friday, coming off a three-week high earlier in the week, as investors considered the potential impact of ongoing geopolitical risks on global oil supply.

Brent crude, the global benchmark, fell nearly 1%, to $56.67 a barrel on London's Intercontinental Exchange. On the New York Mercantile Exchange, West Texas Intermediate futures were trading down 1.15% at $50.70 a barrel.

"We've seen a fairly decent rally, but we are probably starting to see the top end of the range," said Michael Hewson, chief market analyst at brokerage CMC Markets UK PLC.

While oil prices are close to their highest levels seen this year, investors are concerned that pushing prices too high could spur U.S. crude producers to ramp up shale production, Mr. Hewson said. That could exacerbate the global supply glut and undermine the fragile market rebalancing underway, analysts say.

Crude prices climbed earlier in the week after clashes between Iraqi government troops and forces from the semi-autonomous Kurdish region disrupted some oil production and exports. Kurds voted nearly unanimously to break away from Iraq in a controversial independence referendum late last month.

Oil supplies that flow from Kurdistan, in northern Iraq, through Turkey fell to around 196,000 barrels a day on Thursday, compared with a usual supply of around 600,000 barrels a day, according to Dutch bank ING Group.

"A prolonged disruption to this supply could tighten the oil market in Europe," analysts at ING said.

Meanwhile, the head of the Organization of the Petroleum Exporting Countries said Thursday that there is "no doubt the oil market is rebalancing at an accelerated pace." Speaking to a gathering of oil industry executives and experts in London, OPEC Secretary General Mohammed Barkindo insisted that cartel's plan to cut output and rein in the global supply glut was paying off.

However, "not even a slew of supportive comments from OPEC's secretary general succeeded in injecting a dose of bullish impetus," Stephen Brenonck, an analyst at brokerage PVM Oil Associates Ltd., wrote in a note Friday.

OPEC and 10 producers outside the cartel, including Russia, first agreed late last year to cap their production at around 1.8 million barrels a day lower than peak October 2016 levels, with the aim of alleviating global oversupply and boosting prices.

The deal was extended in May through March 2018 and a number of participants have in recent weeks indicated a willingness to prolong the deal through the end of next year. OPEC is set to officially debate an extension at its next meeting in Vienna in November.

Among refined products, Nymex reformulated gasoline blendstock -- the benchmark gasoline contract -- was down 0.90%, at $1.60 a gallon. ICE gasoil, a benchmark for diesel fuel, changed hands at $517.00 a metric ton, down 1.19% from the previous settlement.

Oil prices rose Friday, boosted by disruptions to production in Iraq amid geopolitical conflict.

Light, sweet crude for November delivery gained 24 cents, or 0.5%, to $51.53 a barrel on the New York Mercantile Exchange. Brent, the global benchmark, rose 40 cents, or 0.7%, to $57.63 a barrel.

Crude prices have climbed this week as clashes between Iraqi government troops and forces from the semiautonomous Kurdish region disrupted some oil production and exports. Kurds voted nearly unanimously to break away from Iraq in a controversial independence referendum late last month.

As operations have restarted in Iraq's northern oil fields, about half of production capacity in the region's largest fields appears to be down, according to oil consultancy Kayrros.
