You are right to sell a guarantee to another party in a pension and agree to buy it back at a fixed price in the future and essentially be a guaranteed loan. The difference between the fixed feed-in price and the initial selling price is essentially interest (reseal rate) and is calculated on the basis of money market agreements, since deposits are generally short-term transactions. Mr. Robinhood. “What are the near and far legs in a buyout contract?” Access on August 14, 2020. 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.  Although the transaction is similar to a loan and its economic effect is similar to a loan, the terminology is different from that of the loans: the seller legally buys the securities back from the buyer at the end of the loan period. However, an essential aspect of rest is that they are legally recognized as a single transaction (important in the event of a counterparty`s insolvency) and not as a transfer and redemption for tax purposes. By structuring the transaction as a sale, a repot provides lenders with significant protection against the normal functioning of U.S. bankruptcy laws, such as. B automatic suspension and prevention of provisions. Conversely, with bond prices linked to interest rates, higher interest rates have led to a decline in the value of long-term bonds, and the value of bank-owned guarantees has also declined.
A pension purchase contract (repo) is a form of short-term borrowing for government bond traders. In the case of a repot, a trader sells government bonds to investors, usually overnight, and buys them back the next day at a slightly higher price. This small price difference is the implied day-to-day rate. Deposits are generally used to obtain short-term capital. They are also a common instrument of central bank open market operations. Deposits are traditionally used as a form of secured loan and have been treated as such tax-wise. However, modern repurchase agreements often allow the lender to sell the collateral provided as collateral and replace an identical guarantee when buying back.  In this way, the lender will act as a borrower of securities, and the repurchase agreement can be used to take a short position in the guarantee, as could a securities loan be used.  However, the initial cash would be based on the market value of the guarantees, and as a general rule, the lender would apply a haircut, say 2%, so that you will receive cash of 98% of the market value of the guarantees. The redemption price is calculated on the basis of this initial cash, so you pay interest on what you borrowed. The haircut is intended to protect the lender in the event of a decrease in the value of collateral or to reflect other security-related risks such as illiquidity, incorrect risk, etc.
The intial margin plays a similar role in the Exchange Cleared transaction. Buyback contracts can be concluded between a large number of parties. The Federal Reserve enters into pension contracts to regulate money supply and bank reserves.
