Repurchase agreement

A Repurchase agreement (also known as a repo or Sale and Repurchase Agreement) allows a borrower to use a financial security as collateral for a cash loan at a fixed rate of interest. In a repo, the borrower agrees to sell immediately a security to a lender and also agrees to buy the same security from the lender at a fixed price at some later date. A repo is equivalent to a cash transaction combined with a forward contract. The cash transaction results in transfer of money to the borrower in exchange for legal transfer of the security to the lender, while the forward contract ensures repayment to the loan to lender and return of the collateral of the borrower. The difference between the forward price and the spot price is the interest on the loan while the settlement date for the forward contract is the maturity date of the loan. ==Structure and terminology== A repo is economically similar to a secured loan, with the buyer receiving securities as collateral to protect against default. There is little that prevents any security from being employed in a repo; so, Treasury or Government bills, corporate and Treasury/Government bonds, and stocks may all be used as securities involved in a repo. However, the legal title to the securities clearly passes from the seller to the buyer, or "investor". Coupons (installment payments that are payable to the owner of the securities) which are paid while the repo buyer owns the securities are, in fact, usually passed directly onto the repo seller. This might seem counterintuitive, as the ownership of the collateral technically rests with the buyer during the repo agreement. It is possible to instead pass on the coupon by altering the cash paid at the end of the agreement, though this is more typical of Sell/Buy Backs.

Although the underlying nature of the transaction is that of a loan, the terminology differs from that used when talking of loans because the seller does actually repurchase the legal ownership of the securities from the buyer at the end of the agreement. So, although the actual effect of the whole transaction is identical to a cash loan, in using the "repurchase" terminology, the emphasis is placed upon the current legal ownership of the collateral securities by the respective parties.

Types of repo and related products

There are three types of repo maturities: overnight, term, and open repo. Overnight refers to a one-day maturity transaction. Term refers to a repo with a specified end date. Open simply has no end date. Although repos are typically short-term, it is not unusual to see repos with a maturity as long as two years.

Repo transactions occur in three forms: specified delivery, tri-party, and held in custody. The third form is quite rare in developing markets primarily due to risks. The first form requires the delivery of a prespecified bond at the onset, and at maturity of the contractual period. Tri-party essentially is a basket form of transaction, and allows for a wider range of instruments in the basket or pool. Tri-party utilizes a tri-party clearing agent or bank and is a more efficient form of repo transaction.

Due bill/hold in-custody repo

In a due bill repo, the collateral pledged by the (cash) borrower is not actually delivered to the cash lender. Rather, it is placed in an internal account ("held in custody") by the borrower, for the lender, throughout the duration of the trade. This has become less common as the repo market has grown, particularly owing to the creation of centralized counterparties. Due to the high risk to the cash lender, these are generally only transacted with large, financially stable institutions.

Tri-party repo

The distinguishing feature of a tri-party repo is that a custodian bank or international clearing organization acts as an intermediary between the two parties to the repo. The tri-party agent is responsible for the administration of the transaction including collateral allocation, marking to market, and substitution of collateral. Tri-party agents administer US$ trillions of collateral. They therefore have the scale to subscribe to multiple data feeds to maximise the universe of coverage. They are also able to offer "sophisticated collateral eligibility filters with which to create eligibility profiles which can systemically generate collateral pools which reflect a Buyer's risk appetite". Collateral eligibility criteria could include asset type, issuer, currency, domicile, credit rating, maturity, index, issue size, average daily traded volume, etc. Both the lender and borrower of cash enter into these transactions to avoid the administrative burden of bi-lateral repos. In addition, because the collateral is being held by an agent, counterparty risk is reduced. A tri-party repo may be seen as the outgrowth of the due bill repo, in which the collateral is held by a neutral third party. A Nigerian Open Buy Back is a similar transaction, with the Nigerian Central Bank being the custodian.

Whole loan repo

A whole loan repo is a form of repo where the transaction is collateralized by a loan or other form of obligation (e.g. mortgage receivables) rather than a security.

Equity repo

The underlying security for most repo transactions is in the form of government or corporate bonds. Equity repos are simply repos on equity securities such as common (or ordinary) shares. Some complications can arise because of greater complexity in the tax rules for dividends as opposed to coupons.

Sell/buy backs and buy/sell backs

A sell/buy back is the spot sale and a forward repurchase of a security. It is two distinct outright cash market trades, one for forward settlement. The forward price is set relative to the spot price to yield a market rate of return. The basic motivation of sell/buy backs is generally the same as for a classic repo, i.e. attempting to benefit from the lower financing rates generally available for collateralized as opposed to non-secured borrowing. The economics of the transaction are also similar with the interest on the cash borrowed through the sell/buy back being implicit in the difference between the sale price and the purchase price.

There are a number of differences between the two structures. A repo is technically a single transaction while a sell/buy back is a pair of transactions (a sell and a buy). A sell/buy back does not require any special legal documentation while a repo generally requires a master agreement to be in place between the buyer and seller (typically the SIFMA/ICMA commissioned Global Master Repo Agreement (GMRA)). For this reason there is an associated increase in risk compared to repo. Should the counterparty default, the lack of agreement may lessen legal standing in retrieving collateral. Any coupon payment on the underlying security during the life of the sell/buy back will generally be passed back to the seller of the security by adjusting the cash paid at the termination of the sell/buy back. In a repo, the coupon will be passed on immediately to the seller of the security.

A buy/sell back is the equivalent of a "reverse repo".

Securities lending

The general motivation for repos is the borrowing or lending of cash. In securities lending, the purpose is to temporarily obtain the security for other purposes, such as covering short positions or for use in complex financial structures. Securities are generally lent out for a fee. Securities lending trades are governed by different types of legal agreements than repos.

Reverse Repo

A reverse repo is simply the same repurchase agreement from the buyer's viewpoint, not the seller's. Hence, the seller executing the transaction would describe it as a "repo", while the buyer in the same transaction would describe it a "reverse repo". So "repo" and "reverse repo" are exactly the same kind of transaction, just described from opposite viewpoints.

Uses

For the buyer, a repo is an opportunity to invest cash for a customized period of time (other investments typically limit tenures). It is short-term and safer as a secured investment since the investor receives collateral. Market liquidity for repos is good, and rates are competitive for investors. Money Funds are large buyers of Repurchase Agreements.

For traders in trading firms, repos are used to finance long positions, obtain access to cheaper funding costs of other speculative investments, and cover short positions in securities.

In addition to using repo as a funding vehicle, repo traders "make markets". These traders have been traditionally known as "matched-book repo traders". The concept of a matched-book trade follows closely to that of a broker who takes both sides of an active trade, essentially having no market risk, only credit risk. Elementary matched-book traders engage in both the repo and a reverse repo within a short period of time, capturing the profits from the bid/ask spread between the reverse repo and repo rates. Presently, matched-book repo traders employ other profit strategies, such as non-matched maturities, collateral swaps, and liquidity management.

United States Federal Reserve use of repos

Repurchase agreements when transacted by the Federal Open Market Committee of the Federal Reserve in open market operations adds reserves to the banking system and then after a specified period of time withdraws them; reverse repos initially drain reserves and later add them back.

Under a repurchase agreement ("RP" or "repo"), the Federal Reserve (Fed) buys U.S. Treasury securities, U.S. agency securities, or mortgage-backed securities from a primary dealer who agrees to buy them back, typically within one to seven days; a reverse repo is the opposite. Thus the Fed describes these transactions from the counterparty's viewpoint rather than from their own viewpoint.

If the Federal Reserve is one of the transacting parties, the RP is called a "system repo", but if they are trading on behalf of a customer (e.g. a foreign central bank) it is called a "customer repo". Until 2003 the Fed did not use the term "reverse repo"—which it believed implied that it was borrowing money (counter to its charter)—but used the term "matched sale" instead.

Risks

While classic repos are generally credit-risk mitigated instruments, there are residual credit risks. Though it is essentially a collateralized transaction, the seller may fail to repurchase the securities sold at the maturity date. In other words, the repo seller defaults on his obligation. Consequently, the buyer may keep the security, and liquidate the security in order to recover the cash lent. The security, however, may have lost value since the outset of the transaction as the security is subject to market movements. To mitigate this market risk, repos often are overcollateralized as well as being subject to daily mark-to-market margining. Credit risk associated with repo is subject to many factors: term of repo, liquidity of security, the strength of the counterparties involved, etc.

Repo transactions came into focus within the financial press due to the technicalities of settlements following the collapse of Refco. Occasionally, a party involved in a repo transaction may not have a specific bond at the end of the repo contract. This may cause a string of failures from one party to the next, for as long as different parties have transacted for the same underlying instrument. The focus of the media attention centers on attempts to mitigate these failures.

Market size

The US Federal Reserve and the European Repo Council (a body of the International Capital Market Association) both try to estimate the size of their respective repo markets. At the end of 2004, the U.S. repo market reached US$5 trillion.

The European repo market has experienced consistent growth over the past five years, from €1.9 billion in 2001 to €6.4 trillion by the end of 2006, and is expected to continue significant growth due to Basel II, according to a 2007 Celent report entitled “The European Repo Market”.

Other countries including India, Japan, Mexico, Hungary, Russia, China, and Taiwan, have their own repo markets, though activity varies by country, and no global survey or report has been compiled.
