]SINGAPORE, May 31 (Reuters) - Oil prices rose above $74 a barrel in thin trade on Monday as worries about euro zone economic stability fueled the worst monthly loss for the commodity since December 2008.
U.S. crude <CLc1> for July delivery rose 42 cents to $74.39 by 0249 GMT, after settling down 58 cents on Friday, when a downgrade of Spain's credit ratings and disappointing U.S. economic data fuelled investor caution about riskier assets like oil. [
]Front-month crude fell $12.18, or 14.1 percent in the month of May, the biggest monthly percentage loss since December, 2008, when prices fell 18.1 percent.
London Brent crude <LCOc1> rose 25 cents to $74.27 a barrel. Front-month Brent crude was down $13.42, or 15.4 percent for the month, the biggest monthly percentage decline since November, 2008.

Fitch Ratings downgraded Spain's sovereign credit rating by one notch on Friday, saying the country's economic recovery will be "more muted" than government forecasts due to austerity measures. [
]"It's not a shocking thing any more. People get pretty good idea because in general the feeling is that even the $1 trillion rescue package is not going to solve the problem. It's just confirming what they already know," said Clarence Chu, a trader at Hudson Capital in Singapore.
"We expect the market to be very quiet with very low volume, unless there is some breaking news," Chu said."The oil prices usually move in a tight range during long holidays."
The euro stabilised against the dollar on Monday but remained under downward pressure from the Spain credit downgrade. [
