A term repo is a short-term collateralized loan between financial institutions in which one party sells securities to another for cash and simultaneously agrees to buy those securities back at a slightly higher price on a fixed future date. The “term” means the loan runs longer than a single business day, anywhere from a few days to several months. The U.S. repo market reached roughly $11.9 trillion in gross size in 2024, making it one of the largest funding markets in the world.1Board of Governors of the Federal Reserve System. The $12 Trillion U.S. Repo Market: Evidence from a Novel Panel of Intermediaries Compared with rolling an overnight loan every morning, a term repo gives both borrower and lender something simple and valuable: certainty about cash and rate for the full period.
The Two Legs of a Term Repo
Every repo has two legs. On the opening leg, the cash borrower (the “seller”) delivers securities to the cash lender (the “buyer”) and receives cash. On the closing leg, at the agreed maturity, the borrower buys those securities back at the original cash amount plus interest. That interest is the lender’s compensation for parking its cash, and it is calculated from the repo rate agreed at the start.2BlackRock. Understanding Repurchase Agreements
The repurchase price is locked on day one. Lend $10 million at a 5% repo rate for 30 days, and the interest on an actual/360 day-count basis works out to $10,000,000 × 0.05 × (30/360) = $41,667. The borrower returns $10,041,667 at maturity. Both sides know their cash flows from the opening trade. That is the whole appeal of a term structure.
Collateral and Haircuts
Collateral is what separates a repo from an unsecured loan. The pledged securities give the lender a cushion: if the borrower fails to repurchase, the lender can sell the collateral to recover its cash. In the U.S. market, the most common collateral is U.S. Treasury securities, agency debt, and agency mortgage-backed securities.
The haircut is the gap between the market value of the pledged securities and the cash actually advanced. A 2% haircut on $10 million of Treasuries means the lender hands over $9.8 million. That buffer absorbs any drop in collateral value before maturity. In practice, over 60% of Treasury-backed repos carry a zero haircut because Treasuries are treated as nearly risk-free.3Office of Financial Research. Are Zero-Haircut Repos as Common as Advertised? Haircuts widen for less liquid collateral and for longer terms, because more time means more chances for the collateral to move.
During the life of a term repo, daily margin calls hold the collateralization steady. If the market value of the pledged securities falls, the borrower posts more collateral or returns some cash. If the collateral rises, the lender returns the excess. This daily true-up is what makes a 60- or 90-day repo workable: neither side carries the full price risk of the securities across the term.
What Drives the Repo Rate
The repo rate is the annualized interest implied by the difference between the sale price and the repurchase price. A handful of factors move it:
- Collateral quality. Treasuries command the lowest rates. Agency debt and mortgage-backed securities trade higher, and corporate bonds higher still.
- Term length. Longer terms mean higher rates, reflecting the lender’s lost flexibility and the market’s view of where overnight rates are headed.
- Counterparty credit. A weaker borrower pays a wider spread on identical collateral.
- Supply and demand. Rates spike when many institutions need cash at the same time (quarter-end, tax dates) and compress when cash is plentiful.
For a term repo specifically, the rate bakes in the market’s forward expectation of overnight rates over the full period, plus a liquidity premium that compensates the lender for locking up cash until maturity. That premium is why term rates typically sit above overnight rates on the same collateral.
Two broad categories sit beneath the rate. In a general collateral (GC) repo, the lender specifies a wide class of acceptable securities and the borrower picks which specific bonds to deliver; the trade is really about cash.4Office of Financial Research. OFR Brief: Repo Participant FAQ A “special” repo is the opposite: the lender wants one specific security, often to settle a short sale, and accepts a lower rate to get it. When a Treasury is said to be “on special,” demand for that particular issue is pushing its repo rate below the GC rate.
Term Repos vs. Overnight and Open Repos
The mechanics of overnight, open, and term repos are the same. What changes is duration, and that one variable changes how each type functions.
Overnight repos mature the next business day. They are the most liquid segment of the market but have to be renewed every morning. A borrower who funds a large securities position overnight carries rollover risk: if conditions tighten, the lender might refuse to renew or rates might jump sharply. Open repos run indefinitely with no set maturity and are terminated by either party, typically on one day’s notice.5BlackRock. Understanding Repurchase Agreements
A term repo takes rollover risk off the table. Lock a 30-day term repo and both sides know the funding and the rate for the full month. The borrower won’t face a surprise funding gap, and the lender won’t lose the investment unexpectedly. The trade-off is price. Term rates generally sit above overnight rates on the same collateral, and haircuts tend to run a little wider for longer terms because there is more time for the pledged securities to move before daily margining can catch up.
How Term Repos Settle
Not all repos settle the same way. Three structures dominate the U.S. market, and each one carries a different operational and risk profile.
Bilateral Repos
In a bilateral repo, borrower and lender deal directly. The borrower delivers collateral straight to the lender, who holds it in its own custody account. The lender gets maximum control, but also has to run the operational side of holding, valuing, and returning the securities. Bilateral repos make up the largest single segment of the U.S. market at roughly $4.6 trillion in 2024.1Board of Governors of the Federal Reserve System. The $12 Trillion U.S. Repo Market: Evidence from a Novel Panel of Intermediaries
Tri-Party Repos
Tri-party repos introduce a custodian bank, in the U.S. market Bank of New York Mellon, that sits between the two sides. The custodian holds the collateral, allocates it, handles margin calls, and settles both legs. The structure lets cash lenders participate without building the infrastructure to hold and manage securities themselves.4Office of Financial Research. OFR Brief: Repo Participant FAQ The tri-party segment ran at about $3.6 trillion in 2024.1Board of Governors of the Federal Reserve System. The $12 Trillion U.S. Repo Market: Evidence from a Novel Panel of Intermediaries
Centrally Cleared Repos
FICC’s Government Securities Division (GSD) acts as a central counterparty for cleared repos. Once a trade is matched, GSD steps in as the legal counterparty to both sides and guarantees settlement. The big benefit is netting: GSD collapses each participant’s daily activity into a single net long or short position per security, which dramatically reduces actual deliveries and settlement costs.6Depository Trust & Clearing Corporation (DTCC). Netting and Settlement Services Central clearing also replaces exposure to any individual dealer with exposure to FICC.
Who Uses Term Repos
The term repo market connects institutions with opposite needs: holders of securities who need cash, and holders of cash who need safe short-term returns.
Primary dealers are the heaviest borrowers. They hold large inventories of Treasuries and agency securities and need stable financing for those positions. A dealer carrying $50 billion in Treasuries cannot comfortably fund that book overnight, where a rate spike or a lender pulling back would create an immediate problem. Term repos let dealers lock in financing for days or weeks and insulate the balance sheet from overnight volatility.
Money market funds are on the other side as major cash lenders. SEC rules treat a repo’s maturity as the period until the repurchase date, so a 14-day term repo counts as a 14-day investment for portfolio maturity calculations.7eCFR. 17 CFR 270.2a-7 – Money Market Funds That lets fund managers match a maturity profile precisely: a fund expecting large redemptions in two weeks can invest in a term repo that matures right before the redemption window, earning a slightly higher rate than overnight while keeping the liquidity it needs.
Corporate treasuries with seasonal cash use term repos the same way. A company sitting on $500 million after a bond issuance or ahead of a tax payment date can place the cash in a term repo that matures when the money is needed, earning a predictable return backed by high-quality collateral.8BlackRock. Understanding Repo: A Cash Building Block
Legal Documentation and Default
Nearly all U.S. repo transactions are governed by the Master Repurchase Agreement (MRA), a standardized contract published by SIFMA. The current version dates to 1996 and contains pre-printed standard provisions covering default events, margin maintenance, and close-out procedures. Parties customize terms through supplemental annexes on topics like equity collateral or FATCA tax compliance. Cross-border transactions use the Global Master Repurchase Agreement (GMRA), currently in its 2011 version, which plays the same role internationally. The split matters because default and insolvency rules differ by jurisdiction, and each master agreement is drafted to be enforceable under its own legal framework.9SIFMA. MRA and GMRA Documentation
The legal structure is built so a default does not become a disaster for the non-defaulting side. Because the lender holds legal title to the collateral during the life of the repo, it can liquidate the securities immediately if the borrower fails to repurchase. There is no need to enforce a security interest through the usual lengthy process.
The MRA also includes close-out netting. When a default occurs, all outstanding repos between the two parties are terminated at once. Each transaction is marked to market, and gains and losses across the open trades are netted into a single payment one party owes the other. These netting provisions are drafted to be enforceable in the borrower’s insolvency, meaning a bankruptcy trustee generally cannot cherry-pick the profitable trades while rejecting the losing ones.
Accounting Treatment
The central accounting question for any repo is whether it is a sale of securities or a collateralized loan. Under U.S. GAAP, most repos are treated as secured borrowings. The transferor keeps the pledged securities on its balance sheet and records a liability for the cash received.10Deloitte Accounting Research Tool. Deloitte’s Roadmap: Statement of Cash Flows
ASC 860 governs the classification. For a transfer of financial assets to qualify as a sale, three conditions have to be met: the assets must be isolated from the transferor’s creditors, the transferee must have the right to pledge or exchange them, and the transferor must not maintain “effective control” over the transferred assets. Standard repos fail the effective control test because the borrower has both the right and the obligation to repurchase the securities at a fixed price. That contractual repurchase obligation is the kind of continuing involvement that keeps the trade on the balance sheet as a borrowing rather than a sale.
How Basel III Shapes Term Repo Use
The Basel III framework affects how banks use term repos through several requirements, with the Net Stable Funding Ratio (NSFR) the most directly relevant.
The NSFR requires banks to fund their assets with sufficiently stable sources relative to those assets’ liquidity profiles. For reverse repos (the lending side), Required Stable Funding (RSF) factors step up with maturity. Short-term reverse repos backed by high-quality liquid assets and maturing in less than six months carry only a 10% RSF factor, so the bank needs to hold very little long-term funding against them. Reverse repos maturing between six months and one year jump to 50%, and anything over one year gets a full 100% RSF factor.11Bank for International Settlements. Basel III: The Net Stable Funding Ratio
On the borrowing side the incentive cuts the other way. A bank funding itself through term repos with maturities beyond six months gets more credit for available stable funding than one relying on overnight repos that could vanish tomorrow. The practical effect is that Basel III pushes banks toward moderate-term funding, long enough to count as stable but short enough to keep RSF charges manageable, while discouraging both the shortest and longest maturities. Securities encumbered as collateral in repos lasting a year or more receive a 100% RSF factor, which directly raises the cost of using long-term repos.11Bank for International Settlements. Basel III: The Net Stable Funding Ratio
The leverage ratio is the other Basel III constraint worth noting. Unlike risk-weighted capital ratios, the leverage ratio gives no credit for collateral quality, so even a fully collateralized Treasury repo consumes balance sheet capacity. That creates quarter-end dynamics where dealers trim repo activity to shrink their reported balance sheets, which can temporarily tighten funding across the market.
