* Hedge funds' 10-year T-note net shorts hit record high * Speculative net fed funds shorts rise to seven-month peak (Adds background, details on latest data) Sept 14 (Reuters) - Speculators' net bearish bets on U.S. 10-year Treasury note futures were little changed earlier this week, as the government was set to sell $73 billion in coupon-bearing debt, according to Commodity Futures Trading Commission data released on Friday.
The U.S. Treasury Department sold $35 billion of three-year debt, $23 billion in 10-year notes and $15 billion in 30-year bonds this week to solid investor demand.
Still bearish Treasury bets paid off this week as benchmark 10-year yields touched 3 percent on Friday for the first time in about six weeks.
The amount of speculators' bearish, or short, positions in 10-year Treasury futures exceeded bullish, or long, positions by 682,684 contracts on Sept. 11, according to the CFTC's latest Commitments of Traders data.
A week earlier, speculators held 682,757 net short positions in 10-year T-note futures.
Speculative 10-year net shorts remained close to the 700,514 contracts reached in August.
Hedge funds raised their 10-year T-note net shorts to an all-time peak of 935,061 contracts, while asset managers pared their 10-year net longs to 946,781 contracts from 971,250 the week before.
Bond dealers' net 10-year shorts dropped to 93,528 contracts, the lowest amount since May.
BEARISH RATE BETS GROW Among other Treasury futures, speculators raised their net shorts in two-year T-notes to 197,128, the highest since Feb. 6.
Speculators' net shorts in bond futures increased to 47,090, which was the most since March 2017.
Among interest rates products, speculative net shorts in Eurodollar futures rose to 3.12 million contracts on Tuesday, which was the most since July 29.
Speculators raised their net shorts in federal funds futures to 61,180 contracts, the highest in nearly seven months.
Relatively strong U.S. business and jobs data and signals on more rate increases from Federal Reserve officials have boosted bearish bets on rates futures, analysts said.
