Treasury futures

Definition

Treasury futures (2-, 5-, 10-year notes; the “ultra” 10; the bond and ultra bond) are physically-delivered contracts on US government debt — the standard instruments for interest-rate direction, curve trades, and duration hedging. Their defining mechanical wrinkle: each contract accepts a BASKET of deliverable bonds via conversion factors, so the contract tracks the CHEAPEST-TO-DELIVER (CTD) issue, not a single bond — and the CTD can switch, changing the contract’s effective duration.

How it works / structure

• Specs: $100,000 face (most), price quoted in points and fractions of 32nds (ms-contract-specs — the tick vocabulary differs from equities), quarterly cycle, physical delivery into a deliverable basket with exchange-published conversion factors.
• CTD logic: shorts deliver whichever eligible issue is cheapest after conversion-factor adjustment; the futures price behaves like the CTD’s forward price; rate moves can flip the CTD to a different-duration issue — the embedded “delivery option” that makes bond-futures pricing subtle (strategy-futures-basis covers the basis trade built on it).
• Risk metric: positions are sized in DV01 (dollar value of a basis point), not contracts — curve trades DV01-match legs (strategy-inter-market-spread NOB/curve section).
• What drives it: Fed policy path (event-fomc), inflation expectations (macro-inflation-linkages), and flight-to-quality flows (Treasuries are the crisis destination — the negative equity correlation in most modern stress, with inflation-shock regimes the exception, regime-rate-environments).

When it applies

Rate direction and curve shape theses; equity-book hedging via the stock-bond correlation (with its regime caveat); duration management; relative value vs cash Treasuries (the basis). The platform expresses rate theses here rather than in rate ETFs when leverage efficiency and 1256 treatment matter.

Risk profile & failure modes

• CTD switch surprises: a position’s effective duration changes when the CTD flips — a “10-year” view can quietly become a 7-year view.
• Delivery-month mechanics: longs holding into the delivery month face first-position-day obligations (instrument-futures-contract first-notice discipline).
• Correlation-regime reversal: the bond-hedges-equity assumption inverts in inflation shocks (2022: both fell together) — the hedge is regime-conditional, documented, and must be stated as such (regime-rate-environments).
• Basis stress: leveraged cash-futures basis positions unwound violently in March 2020 (Fed-studied episode — strategy-futures-basis).

Evidence & limits

Contract mechanics, deliverable baskets, and conversion factors are exchange-documented (CME). The CTD/delivery-option pricing literature is established fixed-income mathematics. The stock-bond correlation’s regime dependence is documented across samples (negative in deflation-fear regimes, positive in inflation-shock regimes) — the platform treats the hedging use as conditional on the stated regime, never structural.

Falsifiable-thesis examples

Illustrations only, not signals:

• “The 10-year yield will fall at least 25bp within 3 months (long TY expression), falsified by the yield path.”
• “The 2s10s curve will steepen 20bp+ this quarter (DV01-matched futures legs)” — falsified by the curve change.
