However, despite regulatory changes over the past decade, systemic risks remain for repo space. The Fed continues to worry about a default by a major rean trader that could stimulate a fire sale under money funds that could then have a negative impact on the wider market. The future of storage space may include other provisions to limit the actions of these transacters, or may even ultimately lead to a shift to a central clearing system. However, for the time being, retirement operations remain an important means of facilitating short-term borrowing. The main difference between a term and an open repo is between the sale and repurchase of the securities. Deposits with a specified maturity date (usually the next day or the following week) are long-term repurchase contracts. A trader sells securities to a counterparty with the agreement that he will buy them back at a higher price at a given time. In this agreement, the counterparty receives the use of the securities for the duration of the transaction and receives interest that is indicated as the difference between the initial selling price and the purchase price. The interest rate is set and interest is paid at maturity by the trader.
A repo is a short-term secured credit: one party sells securities to another and agrees to buy them back at a higher price at a later price. The securities serve as collateral. The difference between the initial price of the securities and their redemption price is that of the interest paid on the loan called the pension rate. When the Federal Reserve`s open market committee intervenes in open market transactions, pension transactions add reserves to the banking system and withdraw them after a specified period; Rest first reverses the flow reserves, then add them again. This instrument can also be used to stabilize interest rates and the Federal Reserve has used it to adjust the policy rate to the target rate.  Pension transactions are generally considered a reduction in credit risk. The biggest risk in a repo is that the seller does not maintain his contract by not repuring the securities he sold on the due date. In these cases, the purchaser of the guarantee can then liquidate the guarantee in an attempt to recover the money he originally paid.
However, the reason this is an inherent risk is that the value of the warranty may have decreased since the first sale and therefore cannot leave the buyer with any choice but to maintain the security he never wanted to maintain in the long term, or to sell it for a loss. On the other hand, this transaction also poses a risk to the borrower; If the value of the guarantee increases beyond the agreed terms, the creditor cannot resell the guarantee.
