SINGAPORE, April 26 (Reuters) - U.S. crude futures fell more than $1 on Tuesday as investors reduced risk ahead of a meeting of the U.S. Federal Reserve and after Saudi Aramco's chief executive said the kingdom was not comfortable with current oil prices.
NYMEX crude for June delivery <CLc1> declined as much as $1.08 a barrel to $111.2, and traded at $111.28 a barrel by 0242 GMT. Brent <LCOc1> dropped 66 cents to $123 a barrel.
"We are not comfortable with oil prices where they are today...I am concerned about the impact it could have on the global economy," Aramco's chief executive, Khalid al-Falih, told an industry gathering in Seoul.
Crude snapped three days of gains, sliding along with silver and gold, as investors were uncertain whether the U.S. Federal Reserve would signal a change in its easy monetary policy after a two-day meeting of policymakers wraps up on Wednesday.
"There is some risk reduction because the market wants to watch if Bernanke will say anything about a change of stance," Tetsu Emori, a Tokyo-based commodities fund manager at Astmax Investments, said. "Any change of stance is highly unlikely."
Market participants will look to the post-meeting news conference by Fed Chairman Ben Bernanke on Wednesday -- the first regularly scheduled news briefing by a Fed chief in the U.S. central bank's 97-year history -- to see how the Fed plans to exit from its ultra-loose policy.
"The market is displaying a cautious stance as any signs of the Fed tightening dollar supply would reduce crude gains," said Serene Lim, an analyst at ANZ. "There isn't a lot of fresh development in the Middle East and Libya which is providing a floor to prices."
Saudi Arabia has enough spare crude capacity to meet demand as oil prices extend a gain above $120 per barrel, Falih said, adding that he didn't see any tightness in global oil supply. [
]"They should be happy with the increases, but what Saudi Arabia is looking for is stability in prices," Emori said. "Anything outside of a range of $90-$110 makes them uncomfortable."
MIDDLE EAST
Oil has strengthened in the past few months as protests in Libya spread to other countries in the Middle East and North Africa such as Syria and Yemen, boosting fears of further supply disruptions from the region at a time when demand from key consumers such as China and India continues to rise.
Security forces have arrested about 500 pro-democracy sympathisers across Syria after the government sent tanks to try to crush protests in the city of Deraa, the Syrian rights organisation Sawasiah said on Tuesday.
The independent organisation said it had received reports that at least 20 people had been killed in Deraa since tanks moved in on Monday. [
]Italy, which has been playing a limited role in NATO operations in Libya, decided on Monday its air force would be allowed to bomb selected military targets in the former Italian colony. [
]Refugees fleeing Libya's Western Mountains told of heavy bombardment by leader Muammar Gaddafi's forces as they try to dislodge rebels in remote Berber towns. The capture of the Dehiba-Wazin crossing on the Tunisian border by rebels last week has let refugees flee in cars or on foot along rocky paths, swelling the numbers of Libyans sheltering in southern Tunisia to an estimated 30,000 people.
