NEW YORK, Aug 14 (Reuters) - U.S. Treasury yields slid on

Friday after data showed U.S. retail sales unexpectedly fell in

July, further reducing expectations that the Federal Reserve

will raise interest rates at its policy meeting next month.

U.S. two-year yields, which are sensitive to the outlook for

interest rate moves, fell 1.9 basis points (bps) to 4.121%

. The benchmark 10-year yield was last down at 4.638%
