NEW YORK, Aug 12 (Reuters) - Speculators increased bearish bets on U.S. Treasury two-year note futures in the latest week, with net shorts hitting their largest in 13 months, ahead of a crucial U.S. inflation report for July, Commodity Futures Trading Commission data showed on Friday.
Net shorts on U.S. two-year note futures, which are often sensitive to rate move expectations, surged to 172,221 contracts in the week ended Aug. 9, the biggest since early July 2021.
U.S. Treasury five-year net shorts rose as well to a nearly three-month high of 351,003 contracts in the week ended Aug. 9, CFTC data showed.
Bond investors increased their bearish positions on the shorter end of the curve, expecting a spike in the U.S. consumer price index for July that should keep the Federal Reserve hiking interest rates.
But July's annual CPI came in lower than expected at 8.5%, after a 9.1% rise in June.
Fed funds futures on Friday have priced in a 58% chance of a 50 basis-point hike at the Fed's September policy meeting . Before Wednesday's CPI report, the rate futures market factored in a more than an even chance of a 75-bps tightening next month.
In other maturities, speculators reduced U.S. 10-year note futures' net shorts to 286,478 contracts in the week ended Aug. 9. A week earlier, speculators held 295,490 net short positions.
