A reverse buyback contract (Reverse repo) is the mirror of a repo transaction. In a reverse, a party buys securities and agrees to resell them later, often the next day, for a positive return. Most deposits are overnight, although they may be longer. A Bill Repurchase contract payable has an internal account in which guarantees are held for the lender. As a general rule, the borrower gives the guarantee to the lender, but in this case it is placed in another bank account. This bank account is in the borrower`s name for the period of the agreement. This is not a common agreement, as it is a risky business for the lender, which does not control the guarantees. 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.  In his book «Strategic Facilities Planning: Capital Budgeting and Debt Administration,» Alan Walter Steiss notes that there are few risks in these agreements because the amount of capital is guaranteed and the return is fixed. The pension contract provides guarantees in the form of securities to facilitate the transaction and thereby reduce the risk involved. The securities are sold with the promise of redemption, which makes the transaction a debt instrument instead of a sale. In his book «Securities Lending and Repurchase Agreements,» Frank Fabozzi says, «Retirement transactions are generally short-lived and range from one to 21 days.» However, this agreement can be shaken up if the borrower has to extend the duration of the agreement. A rollover requires the formation of a new contract between the two parties. Banks generally have short-term requirements that usually last for a single day; These agreements are not often rushed. If the Federal Reserve is one of the acting parties, the PC is called a «system repository,» but if they act on behalf of a client (. B for example, a foreign central bank), it is called a «customer repository.» Until 2003, the Fed did not use the term «reverse repo» – which it said implied that it was borrowing money (against its charter), but instead used the term «matched sale.» In the case of Lehman Brothers, deposits were used as Tobashi systems to temporarily mask significant losses due to intentional semi-finished trades during the reference period. This misuse of deposits resembles Goldman Sachs` swaps in the «Greek debt mask», used as the Tobashi regime to legally circumvent the Deficit Rules of the Maastricht Treaty for active members of the European Union, and which allowed Greece to «hide» more than 2.3 billion euros of debt.
