A repurchase agreement
(or repo) is an agreement between two parties whereby
one party sells the other a security at a specified price with a
commitment to buy the security back at a later date for another
specified price. Most repos are overnight transactions, with the
sale taking place one day and being reversed the next day. Long-term reposcalled
term reposcan extend for a month
or more. Usually, repos are for a fixed period of time, but open-ended deals are
also possible. Reverse repo is a term used to describe
the opposite side of a repo transaction. The party who sells and
later repurchases a security is said to perform a repo. The other
partywho purchases and later resells the securityis
said to perform a reverse repo.
While a repo is legally the sale and subsequent repurchase of a
security, its economic effect is that of a secured loan. Economically, the party
purchasing the security makes funds available to the seller and holds the
security as collateral. If the repoed
security pays a dividend,
coupon or partial redemptions during the repo, this is
returned to the original owner. The difference between the sale and repurchase
prices paid for the security represent interest on the loan. Indeed, repos are
quoted as interest rates.
Securities dealers use repos to finance their
securities inventories. They repo their inventories, rolling the
repos from one day to the next.
Counterparties may be institutions, such as money market funds, who have
short-term funds to invest, or they may be parties who wish to briefly obtain
use of a particular security. For example, a party may want to sell the security
short, or they may need to deliver the security to settle a trade with another
party. Accordingly, there are two possible motives for entering into a reverse
repo:
short-term investment of funds, or
to obtain temporary use of a particular security.
In the latter case, the security is called a
special security. In the former case, it is
called general collateral or GC.
Interest rates payable on special repos tend to be lower than
those payable on GC repos. This is because a party reverse repoing a special
security will accept a reduced interest rate on its funds in exchange for
receiving the special security it requires. Economically, the transaction is no
different from cash collateralized securities
lending. Pricing of either type of deal depends upon demand for the desired
security.
Because repos are essentially secured loans, their interest
rates do not depend upon the respective counterparties'
credit qualities. For GC repos, the same rates
apply for all counterparties. Accordingly, GC repo rates—or simply
repo rates—are benchmark short-term interest rates
that are widely quoted in the marketplace. They differ from
Libor rates in that they are for secured loans whereas Libor rates are for
unsecured loans.
