Asset Managers Increased Long Positions in 5-Year and 10-Year Futures Ahead of U.S. Treasury Expanded Buybacks
Nashnova编辑部
In the week before the U.S. Treasury announced an expanded long-bond buyback program, asset managers had already added net longs in 5- and 10-year Treasury futures — while leveraged funds leaned short, setting up a positioning divergence that will test whether the buybacks actually work.
What did asset managers bet on early?
CFTC data for the week ending August 18 shows asset managers added roughly 31,000 contracts in 10-year Treasury futures net longs and about 43,000 contracts in 5-year net longs.
This means → one day before Treasury's August 19 buyback announcement, long-money managers were already positioning for lower long-end yields.
Yet the same week, asset managers cut about 60,000 contracts of net longs in 2-year futures — the buildup was concentrated in the 5- and 10-year tenors, not a broad duration bet.
Speculative funds were doing the opposite?
Leveraged funds and other speculative accounts pushed further into net shorts on some long-duration Treasury futures — the mirror image of asset managers' move.
In plain terms = the institutions managing long-horizon capital were adding longs, while the fast-money crowd was adding shorts. The two camps hold opposite views on long-end Treasuries.
This divergence means → whichever way yields move next, one side faces forced unwinds, likely amplifying volatility.
What exactly did Treasury's buyback do?
On August 19, the Treasury announced it would at least double the size of its liquidity-support buyback operations for 10- to 30-year nominal bonds, raising the per-operation cap from $2 billion to at least $4 billion, effective September 9 through November 4.
The backdrop: long-end yields had been climbing relentlessly — before the announcement, the 30-year yield briefly hit 5.34%, its highest since 2007.
In plain terms = Treasury stepped in when the market was in pain, using real cash to buy back older bonds and inject liquidity into the long end.
How did the market react after the announcement?
Long-end yields dropped sharply right after the announcement, then climbed back up.
This reflects lingering doubt over whether buybacks can sustainably ease Treasury supply-demand pressure — a short-term fix, but perhaps not a lasting one.
This means → the split between asset managers' early longs and speculators' shorts becomes the key gauge of actual buyback effectiveness: if buybacks succeed in capping yields, shorts face a squeeze; if not, the longs take the hit.
