REUTERS/Ramzi BoudinaHOUSTON/WASHINGTON, April 4 (Reuters) - Saudi Arabia and other OPEC+ oil producers announced over the weekend they would launch deep oil production cuts starting next month, a surprise move that sent oil prices surging. If refiners reduce capacity, the drain on stocks could lead to a sudden jump in retail fuel prices, he said. U.S. gasoline prices have climbed 11.6 cents a gallon from a month ago to $3.506, the AAA said on Monday. A 6% jump in oil prices would boost retail gasoline prices 10 cents a gallon, said Mark Finley, an expert in energy policy at Rice University's Baker Institute. OPEC's reason for cutting production - as a precautionary step - suggests it expects global oil demand to slow this year.
