Deposits with longer tenors are generally considered riskier. Over a longer period of time, there are more factors that can affect the creditworthiness of first-time buyers, and changes in interest rates affect the value of the asset repurchased. Banks and other savings banks with surplus cash often use these instruments because they have shorter maturities than certificates of deposit (CD). Long-term pension transactions also tend to pay higher interest rates than night pensions because they have a higher interest rate risk, with a duration greater than one day. In addition, collateral risk is higher for appointment deferrals than for overnight deposits, as the value of assets used as collateral is more likely to lose value over an extended period of time. In 2007-08, a rush to the renudisument market, where investment bank financing was either unavailable or at very high interest rates, was a key aspect of the subprime mortgage crisis that led to the Great Recession.  In September 2019, the U.S. Federal Reserve intervened in the role of the investor in providing funds in the pension markets, when overnight interest rates increased due to a number of technical factors that limited the supply of available resources.   For the party that sells the guarantee and agrees to buy it back in the future, it is a repo; for the party at the other end of the transaction, the purchase of the warranty and the consent to sell in the future, it is a reverse buyback contract. Long-term retirement operations are used as a short-term financing solution or a fixed-term cash investment alternative ranging from a few weeks to several months. By purchasing these securities, the central bank is helping to stimulate the money supply in the economy, which encourages spending and reduces the cost of credit. If the central bank wants the economy to grow, it first sells the government bonds and then buys them back on an agreed date.
In this case, the agreement is called the reverse reference contract. The crisis has revealed problems with the pension market in general. Since then, the Fed has intervened to analyze and reduce systemic risks. The Fed has identified at least three problematic areas: The New York Times reported in September 2019 that it was estimated that a trillion dollars a day of guarantees were being implemented in U.S. pension markets.  The Federal Reserve Bank of New York declares the daily collateral volume of renuating for different types of repurchase agreements. On 24.10.2019, the volume was the overnight guaranteed cash rate (SOFR) of USD 1.086 billion; General collateral rate (BGCR) $453 billion and $425 billion (General Collateral Rate) (TGCR).  However, these figures are not additive, the latter two being only elements of the first SOFR.
 While conventional deposits are generally instruments of 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.
