Oil glut to continue this year, may ease next year: OPEC

The Organisation of Petroleum Exporting Countries said on Friday the global oil market is oversupplied and signalled the glut may increase this year, as surging output from its members makes up for losses from other countries whose production has been hit by a price fall.

Supply from OPEC is climbing after sanctions on Iran were lifted and an initiative with Russia and other non-members to tackle a supply glut by freezing output failed last month.

The oil cartel pumped 32.44 million barrels per day (bpd) in April, it said in a monthly report, up 188,000 bpd from March. This is the highest since at least 2008, according to a Reuters review of past OPEC reports.

"Fundamentally, oversupply still persists," OPEC said in the report published on Friday. "Oil output remains high."

 A persistent surplus could weigh on prices, which despite a recovery to $47 a barrel from a 12-year low of $27.10 in January, are less than half their level in mid-2014. OPEC's 2014 strategy shift to defend market share against higher-cost rival output helped deepen the decline.

 The price drop is hitting non-OPEC supply as companies have delayed or cancelled projects around the world. OPEC forecasts supply from outside producers will decline by 740,000 bpd in 2016 led by the United States, little changed from last month.

OPEC cited factors that could lead to a bigger supply drop, such as the impact of wildfires in Canada that have cut production. The evidence of falling non-OPEC supply should lead to a stronger market next year, it said.

''Outside the US, there have been consistent signs of declines in non-OPEC production, which should likely flip the global oil market into a net deficit in 2017."

But OPEC supply has been climbing since the 2014 policy shift led by top two producers Saudi Arabia and Iraq. The return in December 2015 of Indonesia as an OPEC member has also increased total output.

 So far this year, Iran is driving the growth. Tehran had refused to join the supply freeze initiative and the deal fell apart on April 17 in Doha after Saudi Arabia insisted Iran took part.

 OPEC left its forecast that world oil demand will rise by 1.20 million bpd this year unchanged. It sees demand for OPEC crude averaging 31.49 million bpd in 2016, broadly unchanged from last month's forecast.

The report points to a 950,000-bpd surplus on average in 2016 if OPEC keeps pumping at April's rate, up from 790,000 bpd implied in last month's report.
