A Repurchase Agreement (Repo; RP) is a form of short-term borrowing for dealers in government securities. In the money market, it involves the sale of securities with an agreement to repurchase them at a higher price at a later date. Repos are commonly used as an investment vehicle and play a critical role in the Federal Reserve Board’s monetary policy operations.
Mechanism and Types of Repo Agreements
Basic Structure
In a repurchase agreement, one party sells securities to another party with the agreement to repurchase them at a predetermined price on a specified date. The initial seller receives cash, making it a form of secured borrowing, while the buyer lends cash against the securities, earning interest from the price difference.
Types of Repo Agreements
1. Term Repo:
A repo agreement with a specified end date, typically lasting from one day to one year.
2. Overnight Repo:
A one-day contract where securities are sold and repurchased the next day.
3. Open Repo:
An agreement without a fixed end date, where both parties agree to renew the repo daily, but each party has the authority to terminate the agreement.
Formula for Repo Rate
The repo rate can be understood as the cost of the repurchase agreement and is calculated as:
Applications in Money Markets
Repos are widely used in money markets due to their low risk and high liquidity, benefiting both securities dealers and central banks.
Investment Vehicle
Investors utilize repos to earn interest on excess funds, as the securities involved are typically high-quality instruments like U.S. government securities, reducing the potential risk.
Federal Reserve’s Monetary Policy Instrument
The Federal Reserve uses repos in open market operations to regulate the supply of money. By engaging in repo transactions, the Fed can inject liquidity into the market. Conversely, reverse repos are used to withdraw liquidity.
Historical Context
Repo markets emerged in the early 20th century but gained prominence in the post-World War II era. Their usage surged in the 1970s as a pivotal component of monetary policy. Over time, they have evolved to become a cornerstone of central banking operations globally.
Special Considerations
Credit and Market Risks
While repos are generally considered low-risk, they are not entirely without risk. Potential risks include:
Credit Risk:
The possibility that the counterparty might default on the repurchase obligation.
Market Risk:
Adverse movements in the market value of the underlying securities.
Legal and Operational Risks
Ensuring the enforceability of the agreement and the capabilities of the involved institutions is crucial to mitigating these risks.
Examples
Example 1:
A bank sells $1,000,000 in U.S. Treasury bonds to a mutual fund and agrees to repurchase them in 30 days for $1,002,500. Using the repo rate formula:
Example 2:
Overnight repo where the repurchase price leads to an effective interest rate dependent on daily market conditions.
Comparisons and Related Terms
Reverse Repurchase Agreement (Reverse Repo)
In a reverse repo, the roles are reversed: the buyer in the repo agreement sells the securities back to the initial seller, often used by central banks to withdraw liquidity from the system.
Secured vs. Unsecured Lending
Repos are secured transactions since they involve collateral (securities), unlike unsecured lending where no collateral backs the loan.
