Repo operations (within the context of the Federal Reserve) are Repurchase agreements and are conducted only with primary dealers.

The Fed purchases Treasury, agency debt, or agency mortgage-backed securities from a counterparty, subject to an agreement to resell the securities at a later time.

It’s similar to having a loan that is collateralized with assets. These assets from the banks have a higher value than the loan to protect the Fed against market and credit risk.

Repo transaction temporarily increase the quantity of reserves in the banking system.

The New York Fed began conducting repo operations in September 2019 to ensure supply of reserves is ample and to mitigate risks of money market pressures near year-end that could affect policy implementation of interest rates.

What is a repo?

Repo is a generic name for repurchase transactions (which can include buying or selling). It is a transaction in which one party sells an asset (such as Treasury Bonds) to another party at a set price and commits to repurchase the same assets from the same party at some future date.

If the seller defaults, the buyer is free to sell that asset to a third party to offset their loss. This is what makes a repo very similar to a collateralized or secured deposit.

How is repo rate determined?

The difference between the price paid by the buyer at the start of the repo and the price received at the end is effectively the lending rate on the repo. This is known as the repo rate or repo interest.

Why are repurchase agreements (repos) used?

Repurchase agreements can serve four different functions for various market participants:

1. They are a safe investment
2. Borrowing costs on repos are very cheap
3. Yields can be enhanced for those holding a large amount of safer assets
4. They provides a means for short-selling and short-covering

It’s safe because the cash is secured by collateral, which is generally safe assets. Makes it easy for seller of repo to make money back by selling those secured assets.

Yields are enhanced because a party could lend out a high demand asset to the market, and in return they receive cash for cheap which can be used for funding or reinvesting profits.

Why do banks use repos?

Banks will use repurchase agreements (repos) for short-term borrowing. They do this to raise short-term capital and generally use agreements which are very short-term, generally overnight or 48 hours.

The implicit interest rates on these agreements is known as the repo rate, and is a proxy for the overnight risk-free rate.

Repo can be used for many purposes. One such purpose would be as an efficient source of short-term funding

It also allows institutional investors to meet liquidity requirements without having to liquidate long-term investments. The repo market has become an important source of cash for non-banks to meet Basel regulatory requirements.
