* Speculative 2-year T-note net shorts lowest since August * Speculators' net bearish Eurodollar bets hit 2-1/2-year low (Adds background, details on latest data) March 15 (Reuters) - Speculators' net bearish bets on U.S. 10-year Treasury note futures fell earlier this week to their lowest level in a month, according to Commodity Futures Trading Commission data released on Friday.
Speculators rolled back their futures positioning that U.S. bond yields and interest rates will rise on worries about weakening global growth and signals from the Federal Reserve and other major central banks that they will unlikely raise borrowing costs in the foreseeable future.
The amount of speculators' bearish, or short, positions in 10-year Treasury futures exceeded bullish, or long, positions by 176,434 contracts on March 12, according to the CFTC's latest Commitments of Traders data.
A week earlier, speculators held 233,376 net short positions in 10-year T-note futures.
In other parts of the Treasury complex, speculative net shorts in two-year T-notes fell to 133,391 contracts, the lowest level since Aug. 21.
Speculators' net shorts in ultra bond futures fell to 281,523 contracts, the lowest since Jan. 8.
Among interest rates futures, speculative net shorts in Eurodollar declined to 493,337 contracts, the lowest since Aug. 7, 2016.
Speculators trimmed their net shorts in federal funds futures to 60,858 contracts, marking a six-week low.
