Repurchase agreements or repo agreements are a type of financial transaction used by financial institutions. These agreements involve the sale of securities and other assets from one party to another party with a promise to repurchase the asset at a later date. Typically, repo agreements are used to raise short-term funding for financial institutions.

In a repurchase agreement, the seller agrees to repurchase the asset at a future date. At the same time, the buyer agrees to sell the asset back to the seller on the agreed-upon date. The buyer holds the asset as collateral, and the seller provides cash in exchange for the delivery of the asset.

The interest rate on a repo agreement is the difference between the agreed-upon price and the repurchase price of the asset. The rate is negotiated between the two parties at the time of the agreement. The interest rate is usually lower than other types of short-term funding because the asset is used as collateral.

Repo agreements are used by financial institutions for short-term funding, such as to finance inventory or to cover short-term cash flow needs. They are also used by investors to earn money from cash holdings. Repo agreements can help financial institutions manage their balance sheets and liquidity needs.

Repurchase agreements can be arranged as either bilateral or tri-party agreements. Bilateral agreements are between two parties, while tri-party agreements involve a third-party intermediary, such as a clearinghouse or a custodian. Tri-party agreements provide additional safeguards and oversight to the transaction.
