(Reuters) - The Federal Reserve won't start cutting interest rates until May, traders of futures contracts that settle to the Fed's policy rate were betting on Friday, as the latest read on consumer sentiment suggested rising optimism and appeared to argue against the need for any earlier rate cut. 

On Friday, after a widely watched measure of consumer sentiment rose to its highest level in 2-1/2 years, traders priced in only about a 49% chance of a March rate cut, down from 55% earlier in the day and 77% last week. The probability of a rate cut by May, based on rate-futures pricing, stood at more than 80%.
