If the purpose of the repoe is to borrow money, it is not technically a loan: the ownership of the securities in question actually comes and goes between the parties involved. Nevertheless, these are very short-term transactions with a guarantee of redemption. While conventional deposits are generally instruments that are sifted against credit risk, there are residual credit risks. Although this is essentially a guaranteed transaction, the seller may not buy back the securities sold on the due date. In other words, the pension seller does not fulfill his obligation. Therefore, the buyer can keep the warranty and liquidate the guarantee to recover the borrowed money. However, security may have lost value since the beginning of the operation, as security is subject to market movements. To reduce this risk, deposits are often over-insured and subject to a daily market margin (i.e., if the guarantee ends in value, a margin call may be triggered to ask the borrower to reserve additional securities). Conversely, if the value of the guarantee increases, there is a credit risk to the borrower, since the lender is not allowed to resell it. If this is considered a risk, the borrower can negotiate a subsecured repot.  The only difference is that (i) the asset is sold (and then repurchased) while in (ii) the asset is rather mortgaged as collateral for a loan: in the sale and repurchase transaction, Sn`s ownership and ownership are transferred from A to B and returned in tF from B to A; Conversely, in the case of the guaranteed loan, only the holding is temporarily transferred to B, while the property remains at A.
Retirement transactions are usually short-term transactions, often literally overnight. However, some contracts are open and do not have a fixed due date, but the reverse transaction is usually done within one year. In the case of a reverse repurchase transaction, the opposite happens: the desk sells securities to a counterparty, subject to a subsequent repurchase agreement of the securities at a higher repurchase price. Reverse pension operations temporarily reduce the amount of reserve balances in the banking system. The ON-RRP offer rate (the maximum interest rate that the Federal Reserve is willing to pay for ON-RP transactions) plays a role for the ON-RP counterparties that the interest rate on excess reserves for deposit-taking institutions plays.
