Risk in the Repo Market
Until the last decade or so, the repurchase agreement or "repo" was an arcane financial transaction
familiar only to sophisticated users of the government securities market. Its use has grown rapidly in
recent years, however, and since 1982, eleven
government securities dealers have collapsed
partly as a result of their activities in the repo
market. Their collapse has imposed an aggregate
loss of nearly $1 billion on investors and precipitated a financial crisis of savings banks in the State
of Ohio.
No single factor is responsible for the difficulties
experienced in the repo market. In some cases,
dealer fraud has been alleged, but in other cases,
economic events simply have exposed the risks
inherent in some repurchase agreements. The repo
is a complex legal and economic instrument and
investors have not always been aware of the pitfalls in their use. The purpose of this Letter is to
review briefly the functioning of the repo market
and to explore the sources of its recent problems.
The basic repo transaction
Although a repurchase agreement may be complex
in its details, its basic features are quite simple. In a
repurchase agreement, an investor (or dealer)
purchases securities from a dealer (or other financial institution) who agrees to buy them back at a
future date at a higher price, thereby implicitly paying interest to the investor. A reverse repurchase
agreement is the same transaction viewed from
the dealer's viewpoint. In essence, a repurchase
agreement or "repo" is a mechanism for investing
funds, and a reverse repo is a mechanism for borrowing funds. (Most parties in the market describe
a transaction from the dealer's point of view. Thus,
the above transaction, which both investors and
dealers call a "repo", is lending by the investors and
borrowing by the dealers.)

The role of securities in repos is to provide the
lender with a means of securing collateral for the
funds he has lent. (Legally, there are important distinctions between true collateralized loans and
sequences of purchases and sales. For exposition,
we abstract from these differences here.) Should
the borrower in a repurchase agreement default on

the agreement, ostensibly the lender would be
able to sell the securities to cover the default.
The duration of a repurchase agreement is at the
discretion of the parties involved. It is commonly as
short as one day (so-called "overnight repos"), but
it may last several days, weeks or even months, in
which case it is called a "term" repo. In addition,
the parties may not wish to specify the duration of
the agreement, but rather allow it to be termin~ted
at any time by either party. Such a repo is sometimes called an "open" repo.
A variety of investors find repos attractive for they
offer a convenient and very flexible means of borrowing and lending, particularly for short periods of
time. They are attractive, therefore, to the cash
managers or treasurers of financial institutions,
local governments, school districts, pension funds
and others with fluctuating needs for cash. A local
government, for example, could invest tax receipts
in a repo for several days prior to a payroll date.
The pitfalls
There are three basic sources of risk to an investor
engaging in a repo. The first arises when transfer of
control over the securities may not actually have
occurred as the investor expected. Unless the
investor takes actual, physical, possession of the
securities (or the legal equivalent in the case of
book-entry transfers), for example, there is the risk
that their existence or their freedom from other
liens may have been misrepresented or misunderstood. This aspect of repurchase agreement
construction is known as "gaining control" and
clearly is important to the achievement of the
intended "secured" nature of repo transactions.

A second type of risk can arise if, because of
changes in market conditions, the market value of
the securities involved in the repo has declined
during the life of the agreement below that necessary to fully compensate the lender should the
securities have to be liquidated. Generally,
repurchase agreements contain margin requirements and marking-to-market features designed to
protect the lender from this eventuality. A repo
lender of $10 million, for example, normally will

FRBSF
require that securities worth slightly more than this
amount be transferred to his possession (perhaps 1
to 5 percent more, depending on the volatility of
the securities). This incremental protection is
known as the "margin." Additionally, as market
conditions change during the life of the repo, the
lender can require additional cash or securities to
be placed under his control if the value of the original securities falls to where the margin is
threatened.
For these protective features to be effective, the
lender must be assured of a means of accurately
valuing the securities to which he has gained control. This process is known as "marking-to-market"
and can be quite complex since it involves careful
monitoring of interest (and principal, in the case of
GNMA and other mortgage-backed securities)
accruing to the securities as well as their market
value.
A final but related source of risk to investors in the
repo market arises out of the possibility that the
securities dealer may fail for reasons not directly
related to the investor's repo. Securities dealers
engage in a number of activities and have complex
portfolios subjecting them in the normal course of
business to risk and, as with all firms, failure. If the
securities dealer fails, the investor may be subject
to unanticipated lOsses. This is particularly true, of
course, if the investor's interest in the securities has
not been assured, or if marking-to-market has not
occurred systematically or precisely. The capital
position of the dealer provides some protection for
the investor against mistakes made in theexecution or valuation of the repurchase agreement. It
often is difficult for investors to assess the adequacy of dealer capital since many of the dealers
are unregulated, eliminating one source of external
evaluation. The Federal Reserve System has promulgated voluntary capital adequacy guidelines to
stimulate some market discipline in this regard.

Rights to securities and achieving control
Some of the most widely publicized andserious
problems in the repo market have been due to
ambiguities in the rightsto securities and to the
ability to gain access to the securities when the
dealer failed. It is important first to note that there
are several ways to effect a repo agreement and
that each of these ways implicitly hasconsequences for gaining rights to the securities
involved and the quality of the i'control" achieved

over the securities. No single method is necessarily
"best" in every instance. Rather, each involves a
different tradeoff between risk and cost and,
thereby, the implicit rate of return on the repo
agreement.
The first broad class of repo procedures is sometimes referred to as "deliver against payment," or
simply "delivery," repo because it involves
simultaneous release of the funds and direct transfer of securities control to the lender (or the
lender's account at his own bank) in the repo
agreement. If the securities can be transferred
electronically (which generally is the case with U. S.
Treasury securities), then the release of good funds
by the lender and the transfer of control tothe
securities occurs electronically and simultaneously,
resulting in a perfected lien. Non-wireable
"securities" (such as commercial paper, certificates
of deposit and even individual "whole" loans) also
can be exchanged simultaneously with the release
of funds through the services of a clearing bank.
Since physical paper is being transported, however,
such transactions are expensive and inherently
limited to the immediate locale. In either case,
however, the transaction involvesuback room"
and wire service transactions costs not only of the
funds but more importantly of the securities transferred. These costs tend not to vary significantly
with the size of the transaction and, thus, are economical only for very large repos or those that
extend for some time.
The second broad category of repurchase agreement procedures involves the use of a specified
third party to handle the back room work between
two counterparties and to hold the security collateral during the repo agreement. In formal "triparty" agreements, the dealer's custodian usually a large bank - is also under contract to
protect the investor. The bank holds the securities
in the name of the lender in the repo agreement.
This arrangement is only practical if it is to be used
repeatedly. An alternative method involves
issuance by a bank of a trust receipt for securities
deposited with them as part of a repo agreement.
In either case, having a third party to the agreement provides a more effective avenue of redress
should any problems arise. Such agreements
involve expensive bank custodial or trust fees,
however, and also require substantial effort to
coordinate the relationships among the lender,
securities dealer and the bank. Such agreements

tend not to be used when small amounts of money
are involved in the repo.
A third type of collateral arrangement involves
relying on the securities dealer (who is also the
counterparty in the repo agreement) to continue
to hold the securities (typically at a custodian bank)
instead of transferring control directly to the lender
or to a neutral third party. This makes gaining rights
to the securities more tenuous, however, since the
custodian does not agree to act on anyone's order
but the dealer's. The cost of the transaction is
lowered, of course, since the securities dealer can
avoid formal transfer of the securities and issues
and provide, instead, only informal notification of
where the securities reside (e.g., in a bank).
Obviously, this is an imperfect transfer of control,
exposing the lender to the risk of inadvertent or
fraudulent use of the same collateral in several
repo agreements. Its use relies heavily on the trust
that the repo parties have in one another, and it is
referred to, appropriately, as a "trust me" repo.

Valuation, margin and marking-to-market
In addition to the fundamental problem of obtaining rights to the securities involved in the
repurchase agreement, there is the additional problem of ascertaining their value and the volatility of
their value over the life of the repo agreement.
Problems arise here in a number of ways. The
securities involved may be thinly traded, making it
difficult for the lender to ascertain the market value
of the security quickly. The more complex the
instrument - in terms of call provisions, principal
repayment characteristics, and so on - the more
difficult the valuation problem becomes even if
underlying credit risk can be assessed accurately. In
addition, interest accrual patterns vary widely
among financial instruments and it is important
that the effects that accrued interest have on the
value of the security be assessed accurately and be
appropriately liened. The problem of valuation, of
course, is most difficult in the case of individual,
whole loans such as mortgage loans, which often
are not marketed.
The valuation problem is particularly difficult iithe
securities are long-term ones. Longer term
securities exhibit greater price volatility, and the
value of the collateral can change rapidly even

though the repo agreement itself may be shortterm. The lender must determine the appropriate
margin requirement and, just as importantly, how
aggressively he intends to require marking-tomarket of the collateral. All of these considerations
inevitably involve a tradeoff between risk and
return, since failure to obtain adequate margin
implicitly leaves the lender subject to risk. To avoid
these risks, participants (or their agents) must bear
the additional cost of accurately monitoring the
value of the securities involved and determining
appropriate margin requirements.
It is important to emphasize that margin and marking-to-market considerations also apply in the case
of a reverse repo. In this case, the borrower must
be careful not to allow too much collateral to be
transferred to the control of the dealer from whom
he is borrowing. Remember, in almost all cases,
should the dealer go bankrupt, the value of the collateral given up will exceed the value of the funds
lent. In 1982, institutions that had borrowed from
dealers found themselves in just such a position
because they had failed to consider the value of
accrued interest when valuing securities transferred to the control of the dealer, who ultimately
went bankrupt. Even more recently there have
been losses associated with overcollateralization in
reverse repos.

Risk vs. return
The essential lesson of the repo market is one basic
to economics. Namely, return is increased only at
the assumption of greater risk. Because many of
the costs involved in the repo market do not depend on the size of the transaction but on collateral arrangements and the number and complexity of securities involved, small lenders in the repo
market face a different risk-return tradeoff than
large investors. (Incidentally, a $10 million overnight repo probably would be considered relatively
small by most securities dealers.) Yet small investors - municipalities, school districts, thrifts often overlook this essential fact of the repo
marketplace. They are drawn into transactions by
attractive yields and do not assess risk accurately. It
is only recently that the hazards of ignoring these
tradeoffs have become painfully apparent.
