Crude prices rose on Monday on worries of a summer gasoline crunch in the United States.

Light, sweet crude for August delivery was up 22 cents at 74.15a barrel on New York Mercantile Exchange.

London Brent settled down 24 cents to 77.33 dollars a barrel after hitting 78.40 dollars earlier in the day.

Goldman Sachs said in a Monday research that oil prices could reach 90 dollars a barrel this autumn and 95 dollars a barrel by the end of the year if the Organization of the Petroleum Exporting Countries does not ease production cuts that have helped tighten global markets.
