Haircut
A haircut is a percentage reduction applied to the market value of an asset when it is used as collateral in a financing transaction, such as a repurchase agreement (repo), securities lending, or margin loan. The haircut reflects the lender's assessment of the asset's price volatility and liquidity risk, ensuring that the collateral's adjusted value provides a buffer against potential price declines during the time required to liquidate it.
Key takeaways
- Haircuts are expressed as a percentage: a 10% haircut means an asset with $100 market value is accepted as collateral for only $90 of financing.
- Haircut levels are inversely related to asset quality and liquidity: U.S. Treasury bills typically receive 0-2% haircuts; high-yield bonds may receive 15-30% haircuts; illiquid structured products can face haircuts of 50% or more.
- During financial crises, haircuts often spike dramatically, triggering collateral calls and forced liquidations in a destabilizing feedback loop.
- The procyclical nature of haircuts — widening during market stress and tightening during calm periods — amplifies financial volatility.
- The Basel III/IV framework and regulations such as the Financial Stability Board's haircut floors for non-centrally cleared securities financing transactions seek to limit excessive procyclicality.
Explanation
Haircuts are the primary credit risk management tool in secured financing markets. When a borrower pledges securities as collateral to obtain financing, the lender faces two risks: the borrower may default on repayment, and the collateral's value may have declined by the time the lender can sell it. The haircut provides a buffer against both risks by ensuring that even after a moderate price decline, the collateral still covers the outstanding loan.
The size of the haircut depends on several factors. Volatility is paramount: higher daily price volatility implies a larger potential price move during the liquidation period, requiring a larger buffer. Liquidity — the ease with which a large position can be sold without materially moving the price — is equally critical; illiquid assets require larger haircuts because their effective liquidation cost is higher. Tenor matters as well: a longer-dated repo requiring a larger haircut because there is more time for the collateral to deteriorate in value. Finally, credit quality affects haircuts, particularly for corporate bonds and structured products where default risk adds a layer of uncertainty beyond market price volatility.
The dynamic behavior of haircuts is one of the most important mechanisms through which financial instability propagates. During the 2007-2009 Global Financial Crisis, haircuts on asset-backed securities and other structured products went from effectively zero to 25-40% or more as market participants lost confidence in their underlying quality. This meant that firms that had funded these assets in the repo market suddenly required 25-40 cents of additional equity capital for each dollar of assets — capital they did not have. The resulting forced sales depressed prices further, widening haircuts again and creating the classic 'margin spiral' described by Tobias Adrian and Hyun Song Shin in their influential Federal Reserve research.
Haircut levels across different asset classes are important inputs for risk management systems. Prime brokers publish their standard haircut schedules for different collateral types, and hedge funds must manage their balance sheets with these haircuts in mind, ensuring they have sufficient unencumbered assets to meet potential margin calls even in stressed environments. The effective leverage achievable in a portfolio is directly constrained by the average haircut across the portfolio's assets: if a fund's entire portfolio is pledged as collateral with an average 20% haircut, maximum gross leverage is 1 / 0.20 = 5x NAV.
Formula
Haircut (%) = (Market Value − Loan Value) / Market Value × 100; Maximum Leverage = 1 / Haircut
Example
A hedge fund holds a portfolio of investment-grade corporate bonds with a market value of $100 million and enters into a repo agreement to fund 80% of the portfolio. The prime broker applies a 10% haircut, accepting the bonds as collateral for $90 million of financing. The fund receives $90 million in cash, which it invests in additional assets. Two months later, credit spreads widen sharply and the bond portfolio's market value falls to $85 million. The collateral value after haircut is now $76.5 million ($85M × 0.90), below the $90 million outstanding financing. The prime broker issues a margin call requiring the fund to post $13.5 million in additional collateral or reduce the repo size, forcing the fund to sell assets at depressed prices.
