A small net price exposure can coexist with large gross positions and urgent cash demands. There is no single current, market-wide leverage ratio that captures every basis trade.
What is the Treasury basis trade?
The usual Treasury cash-futures basis trade buys a Treasury security eligible for delivery into a Treasury futures contract, finances the bond through repurchase agreements (repo), and sells the related futures contract. The investor seeks to earn as cash and futures prices converge. The expected return depends on the difference between their prices after carry and repo financing costs; futures delivery options and the cheapest-to-deliver bond affect the calculation.
A positive basis can make this long-cash, short-futures position attractive, but it does not guarantee a profit. The position still has to be financed, and futures margin must be met as required. The Federal Reserve’s 2024 explanation of the trade describes it as a convergence strategy involving Treasury securities deliverable into futures.
How leveraged are Treasury basis trades?
There is no reliable single leverage figure for every trade or a current market-wide ratio established by the cited estimates. A useful calculation depends on its denominator and what it counts: repo borrowing, cash-bond market value, futures notional, supporting capital, and any derivative offsets can produce different answers. State whether a measure is gross or net and whether it includes financing and futures exposures.
#1 Best Overall
| Measure | Reported estimate | What it does—and does not—measure |
|---|---|---|
| Hedge-fund Treasury repo borrowing | $553 billion as of December 2022 | Historical estimate based on SEC Form PF data; Treasury-collateralized repo borrowing by hedge funds, not the borrowing of every basis trade. |
| Capital supporting that borrowing | $9.88 billion as of December 2022 | Historical aggregate estimate paired with the repo-borrowing estimate above. |
| Leverage on that repo borrowing | 56-to-1 as of December 2022 | Federal Reserve estimate for the hedge-fund Treasury repo dataset—not a universal leverage ratio for individual funds or basis trades. |
| Estimated hedge-fund Treasury holdings related to basis trades | $317 billion accumulated since Q1 2022 | Federal Reserve authors’ 2024 estimate, based on their methods; not total market-wide basis-trade notional. |
| Leveraged-fund short Treasury-futures positions | More than $1 trillion in notional exposure by the end of 2023 | Federal Reserve 2024 estimate. Short futures can be held for reasons other than basis trading, so this is not a direct measure of basis positions. |
| Futures initial margin and implied collateral leverage | Illustratively, 1%–3% of contract value and 33:1–99:1, respectively | Federal Reserve Bank of Chicago’s 2026 futures-market illustration; futures collateral alone, not realized leverage for the full cash-futures-repo trade. |
The first three figures are from the Federal Reserve’s 2023 analysis of hedge-fund Treasury exposures, repo and margining. The holdings and futures-position estimates come from its 2024 basis-trade analysis. The illustrative futures-margin figures are described in the Chicago Fed’s 2026 article. These figures have different dates, definitions and scopes, so they should not be combined into one current leverage estimate.
What should a leverage review measure?
Measure the whole financing structure rather than treating futures notional, repo borrowing, a haircut or one margin number as a complete account of risk. At a minimum, record:
- Cash Treasury market value and duration, alongside futures notional and conversion or delivery exposure.
- Repo principal, maturity, rate-reset terms, haircut and renewal rights.
- Initial and variation margin, the timing of calls, and cash available to meet them.
- Collateral already pledged, other encumbrances, and capital allocated to the position.
- Any netting or cross-margining claimed across legs, including the legal entities, agreements and close-out assumptions that make it possible.
Keep gross and net figures separate. A net exposure can help describe price sensitivity, but it does not by itself show how much financing must be rolled, what collateral is tied up, or how quickly cash may be due.

What happens if repo funding dries up?
Repo is short-term financing for a position whose convergence may take longer. If financing costs rise, a lender declines to renew, or dealer capacity contracts, the fund must find replacement cash or reduce the position. Forced sales can turn a temporary funding problem into losses on the securities being sold.

A low or zero haircut on one transaction does not establish that the whole position has little collateral protection: a dealer may assess risk across related positions under portfolio margining, or margin may be assessed elsewhere. The New York Fed reported that two Office of Financial Research pilot collections found a majority of non-centrally cleared bilateral Treasury repo transactions had zero haircuts, while noting that margin could be assessed elsewhere in a portfolio. It also described a Treasury repo market with more than $8 trillion in daily average transaction volume in 2025; that figure is market-wide context, not basis-trade activity. See the New York Fed’s discussion of best practices in U.S. Treasury repo markets.
Repo haircuts and futures collateral requirements are separate. Portfolio margining may recognize offsets between related positions, but an offset at one intermediary can leave the trade dependent on that firm’s continued financing, netting arrangements and operational capacity. The Federal Reserve’s discussion of proportionate margining for repo transactions is relevant to why a trade-level haircut alone may not describe the full margin arrangement.
How do margin calls affect Treasury basis trades?
A sharp move can increase futures variation-margin needs and, depending on requirements, initial margin as well. The cash must be available when the call is due; an expectation that the cash and futures legs will converge later does not pay an immediate margin bill. A liquidity review should therefore measure the amount and timing of potential calls, intraday-call assumptions, the buffer available, and the time needed to raise cash.
Cross-margining may reduce collateral needs when counterparties, eligible positions and arrangements permit offsets between repo collateral and futures delivery exposure. The reviewer should verify which exposures are actually netted, under which enforceable agreements, and how a default or close-out would be handled. Do not treat an offset as dependable merely because it reduces a margin figure in ordinary conditions.

Can a basis trade lose money if it is hedged?
Yes. “Hedged” describes the intended relationship between the positions; it does not mean they will move in lockstep or eliminate funding and counterparty risks. Cash bonds and futures can respond differently to market liquidity, demand, repo rates and delivery economics. Treasury futures are physically settled against an eligible delivery basket, so the short futures position carries delivery obligations and the cheapest-to-deliver bond and delivery options matter.
Rank #4
If the basis widens before convergence, the combined position can lose value. A financing party may also raise margin, reduce services or liquidate positions as conditions change. The CFTC’s 2024 Market Risk Advisory Committee report discusses maturity mismatch and reduced repo availability as channels that can coincide with margin calls.
How should a risk review stress the position?
Test combinations of market and funding shocks, not just a standalone price move. For each scenario, estimate the effect on both legs, the change in financing and collateral requirements, when cash is due, and whether the position can be reduced without relying on normal market depth.
| Scenario | What to examine |
|---|---|
| Basis widens | Loss on the combined cash and futures position before convergence, including whether the legs can be unwound together. |
| Repo costs rise or financing is not renewed | Higher carry costs, replacement-funding availability, maturity mismatch and the cash needed to retain or reduce the bond position. |
| Repo haircut increases | Additional borrower capital required and whether margin elsewhere in the portfolio changes at the same time. |
| Futures margin increases | Initial and variation margin needs, call timing, intraday assumptions and available liquidity. |
| Dealer or other counterparty defaults | Close-out exposure, the enforceability and timing of netting, and access to replacement financing. |
| Both legs face market pressure | Impaired market depth, correlated selling, unwind costs and whether many holders could be trying to reduce similar positions at once. |
What are the market benefits and systemic concerns?
Basis trades can connect demand for Treasury futures with demand for cash securities, supporting price discovery and liquidity, including in off-the-run Treasuries. The concern is not simply that leverage exists: linked cash, futures and repo exposures can make positions sensitive to the same funding and margin conditions. A rapid unwind may put pressure on cash-market prices, futures positioning and financing at the same time. The Federal Reserve’s 2026 analysis of hedge-fund Treasury exposures discusses both the trade’s market role and its interconnected risks.

Stress episodes show why volatility alone is not enough to predict an unwind. The Federal Reserve and CFTC discuss a rapid basis-position unwind associated with Treasury-market stress in March 2020. By contrast, the Dallas Fed reported that basis positions were notably stable during the April 2025 turbulence following higher U.S. tariff announcements: Treasury futures positioning changed little and cash-futures bases were largely unaffected. See the Dallas Fed’s 2025 account. Funding conditions, market structure, position composition and the nature of the shock affect the outcome.
Risk-management review checklist
- Map cash Treasury, futures, repo, clearing and collateral legs by legal entity and counterparty.
- Calculate gross and net exposures, state each denominator, and specify whether futures, repo financing and derivative offsets are included.
- Document repo maturity, renewal terms, rate resets, committed capacity, haircut schedules and rights to increase margin or terminate financing.
- Record futures initial- and variation-margin processes, liquidity buffers, intraday-call assumptions and the time required to raise cash.
- Validate portfolio-margin and cross-margin offsets against enforceable documentation, eligible positions, operational arrangements and default close-out treatment.
- Stress basis widening together with higher repo costs, haircut increases, financing withdrawal and futures-margin changes; include correlated selling and impaired market depth.
- Review counterparty concentration, wrong-way risk, limits, valuation sources and escalation triggers.
- Interpret haircut data in context: a zero haircut on one repo leg may coexist with margin elsewhere, and missing netting or cross-margin data can make effective protection difficult to infer.
In June 2025, the New York Fed summarized Treasury Market Practices Group recommendations for prudent risk management across Treasury repos, including haircuts or margin where appropriate alongside other measures, and documentation describing the margining regime. The stated recommendation was for firms to prioritize material exposures and complete implementation by June 2026. This is a recommendation and timeline; it does not establish that every firm completed implementation.
