In finance, "haircut" carries a different weight than the beauty salon. A financial haircut in finance refers to the difference between the market value of an asset used as collateral and the loan amount extended to a borrower. This article aims to demystify the concept of haircuts in finance, discussing its various types, calculations, and applications in risk management and sales.

What is a Haircut in Finance?

A haircut in finance refers to the percentage reduction applied to the market value of an asset when it is used as collateral for a loan. The haircut amount is the lender's financial institution's safety cushion if the borrower defaults. For example, if a financial institution extends a loan using government bonds as collateral with a 10% haircut, the loan amount would be 90% of the bonds' current market value.

Haircut Rule in the Stock Market

The "haircut rule" in stock trading often refers to the mandatory reduction applied to a stock's value when used as collateral in margin accounts. This reduction varies but is designed to offset risk.

Importance in Financial Markets

Haircuts play a pivotal role in the financial markets. Government securities dealers, market makers, and commercial banks often use haircuts to manage volatility and liquidity risks.

What Does a 20% Haircut Mean?

A 20% haircut implies that the lender devalues the collateral asset by 20%. If government bonds worth $100,000 are used as collateral, the maximum loan amount extended would be $80,000. The lender determines a sufficient amount of the Haircut based on asset volatility and risk.

Haircut vs. Margin Ratio

The haircut and margin ratio are closely related but distinct concepts. While a haircut is the percentage reduction applied to the market value of an asset used as collateral, the margin ratio refers to capital requirement, the percentage of the asset's value that must be maintained in the trading account.

Calculating a Haircut

To calculate a haircut, one must consider the asset's purchase price, current market value and the Haircut's percentage form. The formula is:

Loan Amount=Market Value−(Market Value×Haircut Percentage)Loan Amount=Market Value−(Market Value×Haircut Percentage)

Example in Repo Transaction

In repurchase agreements (repos), haircuts are often calculated using the percentage difference between the buying and selling price of the asset. If the selling price is $100 and the buying price is $90, the Haircut is 10%.

Haircut in Sales and Banking

In sales, a haircut often refers to the fee market makers charge for facilitating transactions at market prices. Similarly, in banking terms, the concept is used by central banks to determine the loan amount in overnight borrowing deals with financial institutions.

Types of Haircuts in Finance

  • Standard Haircut: A fixed percentage applied universally.
  • Risk-based Haircut: Tailored based on the asset's risk profile.
  • Compressed Haircuts: Smaller haircuts are used in low transaction cost environments.

Why Do Banks Use Haircuts?

Banks and other financial institutions use haircuts primarily to manage risk. Central banks lend money to financial institutions with collateral, applying a haircut to assets to account for price fluctuations and the risk of financial loss.

Increase in Haircuts on Collateral

If haircuts on collateral assets increase, the result would be a reduced loan amount. Financial institutions need little collateral to maintain sufficient deposited securities to meet capital requirements.

Bond and Debt Haircuts

In the bond market, a bond haircut refers to the difference between its market price and the value at which it is accepted as collateral. Debt haircuts reduce the market price, total cost or value of a borrower's liability, often negotiated when the borrower cannot repay the debt.

Haircut Value at Risk

Market makers often use the haircut value at risk to set their spreads on financial instruments. It accounts for the maximum potential loss in holding an asset. The market maker's spreads serve as fees market makers charge for their services.

Haircuts for Retail Traders

Retail traders often deal with haircuts when trading on margin. Brokerage firms apply haircuts to equity positions to manage the risk involved. For instance, margin accounts may require a 30% haircut on deposited securities, meaning the asset's total value must be 30% more than the requested margin loan amount.

The Role of Haircuts in Repo Transactions

Haircuts are a critical risk mitigation tool in repurchase agreements, commonly known as repos. A repurchase agreement is a form of short-term borrowing, often used by government securities dealers and financial institutions to raise capital. In a typical repo transaction, one party sells a financial instrument, usually government bonds, to another party with the agreement to repurchase it later at a predetermined price. The difference between the selling and repurchase prices is the loan's interest.

Calculation of Haircut in Repos

The haircut calculation in a repo transaction involves the buying and selling price of the asset used as collateral. For example, if the selling price of a government bond is $100 and the agreed-upon repurchase price is $102, the interest rate for this repo would be $2. If the buying price is $90 due to applying a haircut, the haircut amount would be $10 or 10%.

Technical Aspects of Repos

Repo transactions are often short-term, with many being overnight borrowing deals. However, the term can range from one day to several months. The rate at which the repurchase occurs is known as the repo rate, and it is different from the Haircut. While the Haircut serves as a risk-management buffer, the repo rate acts as the cost of borrowing.

Risk Management and Haircuts

Haircuts in repo transactions are designed to offset the risk of lending money against collateral whose market value may fluctuate. The Haircut depends on various factors, such as the borrower's creditworthiness, the collateral value or asset's volatility, and current market conditions. For instance, a higher haircut might be applied to collateral that is more volatile or less liquid. In this way, the lender protects itself from potential financial loss if the borrower defaults and the value of the deposited securities decreases.

Importance of Accurate Haircut Levels

Determining the correct level of Haircut is crucial for both financial institutions and third parties. If the Haircut is too low, the lender risks exposure to financial loss. If it's too high, it might discourage potential borrowers from engaging in repo transactions, as they would need to deposit a more significant amount of collateral to obtain the same loan amount. Financial institutions, therefore, take great care in setting haircut levels, often using sophisticated models to assess the appropriate percentage reduction based on price predictability, market volatility, and the borrower's credit profile.


Understanding the intricacies of haircuts in finance is essential for individual and institutional investors. From determining loan amounts to managing various types of risk, the concept of larger haircuts is deeply embedded in the financial system. Whether you're dealing with repurchase agreements, market maker's spread, or simply trading on margin, the term "haircut" is indispensable in the vocabulary of finance.
