Crowded Short Positions in U.S. Treasury Futures Raise Short Squeeze Risk
nashnova research
Short positions in U.S. Treasury futures have swelled to multi-year extremes, with asset managers adding over 100,000 ten-year contracts in a single week — any unexpectedly soft data could trigger a squeeze and a sharp, sudden drop in yields.
How crowded is the short side?
The five-year contract added positions on 11 of the past 12 trading days; the ten-year, on 13 of 14. New money has piled onto the short side almost every session.
Combined new risk exposure across the two tenors: roughly $32 million per basis point, equivalent to about $75 billion in five-year cash bonds. This means → the short camp is large enough that even a modest surprise could set off a stampede.
CFTC data show asset managers added over 100,000 ten-year short contracts in the week ending September 22 — one of the largest single-week increases since 2023.
Why are they betting against Treasuries?
The yield curve has climbed to multi-year highs across all tenors; the 30-year hit its highest since 2002. The trend still points up, and shorts are still profitable.
Bank of America strategist Meghan Swiber noted that trend signals from commodity trading advisors remain "firmly short" U.S. Treasuries.
Heavy corporate-bond issuance and rising energy prices — feeding inflation expectations — provide two extra tailwinds for the bearish bet.
Are all these shorts directional bets?
Not entirely. Analysts point out that part of the futures short interest reflects basis trades — arbitraging the gap between futures and cash bonds — and hedging by asset managers, rather than pure directional wagers.
JPMorgan's client survey shows that, as of the week ending September 28, long positions remain at their highest since November 2025. In plain terms = the market is not unanimously bearish; both sides are adding chips.
Put-option premiums on the 30-year contract surged to their highest since August. This reflects that even investors holding long positions are paying up for insurance against further yield rises.
What could trigger a squeeze?
Two key releases this week: the Fed's preferred inflation gauge on Wednesday and the September non-farm payrolls report on Friday.
Economists forecast about 90,000 new jobs in September, well below August's surprisingly strong 162,000. This means → a significant miss to the downside would force shorts to cover en masse, potentially sending yields sharply lower in a matter of hours.
In plain terms = the more crowded the short side, the more violent the reversal — that is the mechanics of a short squeeze.
