Global oil supply glut to 'shrink dramatically' this year: IEA

Demand for oil worldwide is set to grow at a "solid" rate in 2016, with India the "star performer" after making up nearly 30 percent of the global increase in demand in the first quarter of the year, the IEA said.

"This provides further support for the argument that India is taking over from the China as the main growth market for oil," the 29-nation IEA said in its closely watched monthly report.

The oil market has for months been depressed by vast oversupply, badly hurting producers but meaning lower prices at the pump for consumers.

Oil prices surged to six-month highs this week and are well over $46 a barrel after plummeting below $30 early in the year. They are nevertheless far below the $100-a-barrel mark of mid-2014.

In Canada devastating wildfires near Fort McMurray forced a shutdown of 1.2 million barrels a day (mb/d) of production early this month.

The IEA said the events in Canada, however, had not sent oil prices sharply higher, as would have been expected some years ago, with crude having shown little reaction amid overall improved market sentiment.

Iran, the IEA said, had provided the other surprise.

Its oil production and exports increased slightly faster than expected following Iran's return to the market after the lifting of sanctions in January under its nuclear deal.

Iranian oil production in April was nearly 3.6 mb/d, a level last achieved in November 2011 before Western sanctions against Tehran were tightened, the IEA noted.

"Even more important for global markets, oil exports reached 2 mb/d, a dramatic increase from the 1.4 mb/d seen in March," it added.

The rise in Iran helped push production within OPEC (Organization of the Petroleum Exporting Countries) 330,000 b/d higher in April, the group's highest level in more than seven years.

The flow out of Iran also offset concerns about falling production in Libya, Nigeria -- which is facing pipeline sabotage and security issues -- and Venezuela, grappling with power cuts and other shortages, the agency said.

All eyes will be on OPEC kingpin Saudi Arabia, which has just replaced oil minister Ali al-Naimi after two decades in the post, at the June 2 OPEC meeting for signs of major policy changes on its oil supply.

Riyadh held production steady, IEA said.

Outside of OPEC, the IEA said it now forecasts a bigger fall in production, of 800,000 mb/d, from its initial estimate of 700,000.

The agency said the latest figures confirmed "the direction of travel of the oil market towards balance".

Global oil stocks are now expected to increase by 1.3 mb/d in the first half of 2016 with a "dramatic reduction" in the second half, to 200,000 mb/d.

The Paris-based IEA said it was leaving unchanged its outlook for global oil demand growth in 2016, at 1.2 mb/d.

Furthermore, on prices, the IEA said further rises were likely to be "limited" due to plentiful stocks.

Stocks within the Organisation for Economic Cooperation and Development (OECD) countries grew at the start of the year at the slowest pace since the fourth quarter of 2014, the IEA said. They declined in February for the first time in a year.
