TREASURIES-Bonds add losses after 5-year note auction

NEW YORK, Aug 27 (Reuters) - U.S. government debt prices lost more ground on Thursday after data showed below-average demand at a $22 billion auction of new five-year Treasury notes.

The price on five-year Treasury notes US5YT=RR, which moves inversely to its yield, was down 12/32. The five-year yield was 3.10 percent, compared with 3.09 percent shortly before the auction results and 3.02 percent late Wednesday.

The benchmark 10-year Treasuries' price US10YT=RR was 16/32 lower for a yield of 3.83 percent versus 3.82 percent right before the auction results. The 10-year yield ended at 3.77 percent late on Wednesday.
