Oil at highest since 2015

London : Oil rose further above $68 a barrel yesterday to the highest since May 2015, supported by unrest in Iran that has raised concerns about supply risks, cold weather in the United States which is boosting demand and OPEC-led output cuts.

Six days of anti-government protests in OPEC’s third-largest producer have added a geopolitical risk premium to oil prices, although Iran’s production and exports have not been affected.

Brent crude LCOc1, the international benchmark, was unchanged at $67.84 a barrel at 1151 GMT and traded as high as $68.27. U.S. crude CLc1 rose 20 cents to $61.83 and also touched the highest since May 2015.

“The protests in Iran add more fuel to the already bullish oil market mood,” said Norbert Rucker, head of commodity research at Swiss bank Julius Baer.

“We believe that today’s oil prices project an overly rosy picture, stick to our cautious view and see the market at risk of profit-taking,” Rucker added.

Freezing weather in the United States has spurred short-term demand, especially for heating oil.

Aside from the spike in May 2015, oil is trading at its highest since December 2014 - the month in which the Organisation of the Petroleum Exporting Countries decided to stop cutting output, a move that deepened a price collapse.

Analysts at JBC Energy said the price reaction to the Iranian unrest was overdone.

OPEC, supported by Russia and other non-members, began to hammer out a deal to cut supplies again in 2016, aiming to lift prices by removing a glut built up in the previous two years.

Their cuts started a year ago and compliance has been high, aided by involuntary output declines in Venezuela, whose economy is collapsing, plus unrest in Nigeria and Libya. Producers have decided to extend the deal until the end of 2018.
