Large Treasury short positions increase squeeze risk

Asset managers increased short exposure in 10‑year Treasury futures by more than 100,000 contracts in the week ended Sept. 22, while open interest in five‑ and 10‑year futures rose sharply in recent sessions, creating crowded bearish positioning that could prompt rapid repositioning if economic data or Federal Reserve commentary shift.

CME data show open interest in five‑year futures rose in 11 of the past 12 trading sessions and in 10‑year contracts in 13 of the past 14 sessions. Commodity Futures Trading Commission data recorded one of the largest weekly additions to short exposure in 10‑year futures since 2023 for the week ended Sept. 22.

Traders have pushed yields higher across the curve. Thirty‑year Treasury yields reached their highest levels since 2002, and the increase in futures activity has accompanied broader selling pressure as investors position for further rises in yields. A large pipeline of corporate bond issuance and higher energy prices have added to supply and inflation considerations in fixed‑income markets.

Market participants are focused on two key releases this week: the Federal Reserve’s preferred inflation gauge scheduled for midweek and September payrolls due at the end of the week. Economists surveyed expect payrolls to show roughly 90,000 jobs added in September. If those reports are materially weaker than forecasts, holders of large short positions could cover quickly, moving yields lower.

Traders estimate the additional risk accumulated across five‑ and 10‑year futures since the start of last week is about $32 million per basis point, equivalent to roughly $75 billion of exposure in the five‑year cash Treasury market. That measure reflects the concentrated size of futures positions that gain from higher yields.

Not all recent futures flows represent outright bearish bets. Some activity reflects basis trades against cash Treasuries or hedges for existing bond holdings. A weekly JPMorgan client survey through Sept. 28 found investor positioning broadly unchanged over the week, with outright long positions at their highest level since November. Bank of America strategists view futures positioning as tilted toward higher yields, with short positions still profitable across short‑ and intermediate‑duration maturities.

Options markets show concentrated activity in short‑term rate contracts. Open interest in SOFR‑based options has grown around several key strikes across December 2026, March 2027 and June 2027 contracts, notably at the 96.625, 97.00 and 97.375 strikes. Traders have bought structures such as June 2027 96.625/97.375 call spreads and increased open interest in certain December 2026 put strikes.

Premiums in Treasury options indicate demand for protection against further yield increases. The cost of hedging long‑bond futures has fallen, leaving put options relatively more expensive than calls and reflecting stronger demand for downside protection.

The concentration of short positions and elevated open interest mean markets could move quickly if incoming data or Fed remarks alter the outlook for rates. Investors and traders are monitoring the upcoming releases for signs that would prompt rapid coverage or re‑establishment of positions in futures and options markets.
