Deposits were traditionally used as a form of secured loan and were treated as such for tax purposes. However, modern repurchase agreements often allow the cash lender to sell the security provided as collateral and replace an identical security at the time of redemption.  In this way, the cash lender acts as a borrower of securities and the repo contract can be used to take a short position in the security, much like a securities loan could be used.  The distinguishing feature of a tripartite repo is that a deposit bank or international clearing organization, the tripartite agent, acts as an intermediary between the two parties to the repo. The tri-party agent is responsible for the management of the transaction, including the allocation of guarantees, labelling to the market and the substitution of guarantees. In the United States, the two main tri-party agents are The Bank of New York Mellon and JP Morgan Chase, while in Europe, the main tri-party agents are Euroclear and Clearstream, six offering services in the Swiss market. The size of the U.S. tri-party repo market peaked in 2008, before the worst effects of the crisis, with about $2.8 trillion and stood at about $1.6 trillion in mid-2010.  While conventional deposits are generally credit risk instruments, there are residual credit risks.
Although it is essentially a secured transaction, the seller can no longer redeem the securities sold on the maturity date. In other words, the repo seller is no longer in default in his commitment. Therefore, the buyer can keep the guarantee and liquidate the guarantee to recover the money loaned. However, the security may have lost its value since the beginning of the transaction, as the security is subject to market movements. In order to reduce this risk, deposits are often over-undersured and are subject to a daily market margin (i.e. if assets lose value, a margin call can be triggered to ask the borrower to publish additional securities). Conversely, when the value of the security increases, the borrower runs a credit risk, since the creditor is not allowed to resell them. If this is considered a risk, the borrower can negotiate a subsecured repo.  According to Yale economist Gary Gorton, Repo has become a secured lending method that is made available to government-provided deposit insurance in the traditional banking sector, with collateral being a guarantee for the investor.  One theory says that it is possible to accredit as a guarantee contract for a third party beneficiary, given that credits are motivated by the buyer`s necessity and that, in application of Jean Domat`s theory, the cause of a credit is that a bank issues a loan in favor of a seller in order to release the buyer from his commitment, to be paid directly to the legal tender seller. There are indeed three different entities that participate in the accrediting transaction: the seller, the buyer and the banker.
Therefore, a credit corresponds theoretically to a guarantee contract accepted by the conduct, or, in other words, to an implied contract.  It is briefly referred to as the LOC Repurchase agreement, which allows both parties to benefit from it. Bondholders use bonds as collateral to obtain cash through a buy-in transaction. This is a loan, since the agreement provides that bondholders pay more for the purchase of assets than they have sold. The counterparty (usually a bank) will be guaranteed a profit as long as the transaction is not in default. GCF trading is a version that streamlines the process. A guarantee contract is generally a fixed-term contract concluded against the party for who who benefit the contract operates and undertakes to conclude the main or main contract, which includes additional conditions for the same purpose as the main contract.  For example, a contract of guarantee is concluded when one party pays the other party a certain amount for entry into another contract. . .
