Oil prices fell to $113 a barrel Tuesday in Asia as a stronger U.S. dollar made crude more expensive for investors with other currencies.

Benchmark crude for June delivery was down 49 cents at $113.03 a barrel at midday Singapore time in electronic trading on the New York Mercantile Exchange. The contract fell 41 cents to settle at $113.52 on Monday.

In London, Brent crude for June delivery was down 42 cents to $124.70 a barrel on the ICE Futures exchange.

Crude has jumped 34 percent since mid-February, fuelled disruption oil supplies in Libya and a weaker dollar. On days when the dollar rallies, commodities such as oil tend to fall.

The euro fell to $1.4818 on Tuesday from $1.4823 late Monday.

Traders are also mulling the impact of the death of Osama bin Laden in Pakistan on Sunday. Some are concerned about revenge attacks on U.S. targets while others estimate a weaker al-Qaeda lowers the risk that terrorism will destabilize the oil-rich Middle East.

Some analysts consider bin Laden’s death a minor issue for the oil market, and are more focused on U.S. monetary policy. Federal Reserve Chairman Ben Bernanke said last week that the U.S. would keep interest rates low for an extended period; comments that helped weaken the dollar.

“In a number of respects, Ben Bernanke is much more central to the future of oil prices than Osama bin Laden,” Cameron Hanover said in a report. “We have seen the impact a weaker U.S. dollar has had on oil prices.”

In other Nymex trading in June contracts, heating oil fell 1.1 cents to $3.24 a gallon and gasoline dropped 1.3 cents to $3.34 a gallon. Natural gas futures were up 0.1 cents at $4.70 per 1,000 cubic feet.
