Naimi says no OPEC boost until stocks fall - report

VIENNA (Reuters) - OPEC would wait until crude inventories fell to around 53 days of forward cover before considering raising output, Saudi Oil Minister Ali al-Naimi was reported as saying in remarks published late on Friday.

OPEC left output targets unchanged at a meeting on Thursday, as higher oil prices and optimism the global economy would soon start to recover outweighed concern over high crude stocks.

The oil price hit a six-month high over $66 a barrel on Friday.

"We will wait until inventories are at the level which we consider reasonable, which is about 53 days of forward cover," the minister for the top oil exporter told industry publication Petroleum Argus in an interview, when asked what would prompt OPEC to increase supply. "I think that is a fair level."

Oil stocks stand at around 62.4 days of cover, according to the International Energy Agency. Recession has caused the sharpest fall in demand in nearly three decades, so oil in stocks covers more days of demand.

But if demand picks up, the days of forward cover would fall without OPEC taking more oil off the market, Naimi said.

The rally in prices was sustainable, Naimi said. Oil has more than doubled from a December low of $32.40 a barrel.

"I believe it is highly sustainable," he said. "I believe it is reflecting increased demand, improved economic recovery and confidence in national policies that have been adopted by many countries to improve the economy."

State oil giant Saudi Aramco has capacity to produce above 12.5 million bpd if needed, without including capacity in the neutral zone between the kingdom and Kuwait, Naimi said.
