Rehypothecation in Repo Agreements: What You Need to Know

Repo agreements, also known as repurchase agreements, are commonly used in the financial world as a way to raise short-term capital. In simple terms, a repo agreement involves one party selling a security to another party with the agreement to repurchase the security at a later date for a slightly higher price. However, there is a lesser-known aspect of repo agreements that can have significant implications for both parties involved: rehypothecation.

Rehypothecation is the practice of using a security that has been posted as collateral for a loan to secure additional loans. In the context of repo agreements, it means that the party that receives the security as collateral from the borrower (known as the repo buyer) can pledge the security as collateral for their own borrowing needs. This can happen multiple times, creating a chain of rehypothecation.

While rehypothecation can be a useful tool in financing and investing, it also carries risks. For example, if the original borrower defaults on their obligation to repurchase the security, the repo buyer may find that the security they are holding has been pledged multiple times and is therefore no longer fully collateralized. This can lead to a loss for the repo buyer, who may not be able to recover the full amount of the loan from the collateral.

There are also regulatory considerations when it comes to rehypothecation. In some jurisdictions, there are limits on how much a party can rehypothecate a security. For example, in the European Union, the European Market Infrastructure Regulation (EMIR) sets out rules on the maximum amount of reuse of collateral that is allowed. However, these regulations may not apply in all jurisdictions, so it is important for parties involved in a repo agreement to understand the laws and regulations in their specific jurisdiction.

To mitigate the risks associated with rehypothecation, parties can negotiate specific terms around how collateral is used. For example, a borrower may require that their securities cannot be rehypothecated beyond a certain limit. Alternatively, a repo buyer may require that they have the right to recall the collateral at any time to ensure that it is not being re-used beyond their comfort level.

In conclusion, rehypothecation is a practice that can have significant implications for both parties involved in a repo agreement. While it can be a useful tool in financing and investing, it also carries risks and may be subject to regulatory limits. Parties should carefully consider the implications of rehypothecation and negotiate specific terms to mitigate risks and ensure that their interests are protected.
