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.“ First, Bear Stearns, then Lehman, could not sell enough deposits to pay these lenders. Soon, no one wanted to pay them anymore. It got to the point where Lehman didn`t even have enough money at his disposal to make pay slips. Before the crisis, these investment banks and hedge funds were completely unregulated. In 1982, the failure of Drysdale Government Securities resulted in a loss of $285 million for Chase Manhattan Bank. The result was a change in the use of accrued interest in calculating the value of pension securities. That same year, the failure of Lombard-Wall, Inc. led to a change in federal insolvency laws with respect to deposits.
  The failure of ESM Government Securities in 1985 led to the closure of the Home State Savings Bank in Ohio and a rush to other banks insured by the Ohio Deposit Guarantee Fund. The failure of these and other companies led to the passage of the Government Securities Act of 1986.  A buy/sell back is a „reverse repo.“ For traders of commercial enterprises, deposits are used to finance long positions, to access cheaper financing costs of other speculative investments and to cover short positions in securities. Repo is a form of guaranteed loan. A basket of securities serves as an underlying guarantee for the loan. Securities law is transferred from the seller to the buyer and returns to the original owner after the contract is concluded. The most commonly used guarantees in this market are U.S. Treasury bonds. However, government bonds, agency securities, mortgage-backed securities, corporate bonds or even shares can be used in a repurchase transaction. In particular, Part B acts as a lender in a pension institution, while Seller A acts as a cash borrower and uses the guarantee as collateral; in an inverted repo (A) is the lender and (B) the borrower. A pension is economically similar to a secured loan, with the buyer (actually the lender or investor) obtaining guarantees to protect themselves from a seller`s default.
The party that sells the securities at first is actually the borrower. Many types of institutional investors conduct repo transactions, including investment funds and hedge funds.  Almost all guarantees can be used in a repo, although highly liquidated securities are preferred, as they can be sold more easily in the event of default and, more importantly, they can easily be obtained on the open market, where the buyer has created a short position in the pension guarantee through an inverted repo and a sale in the market; at the same time, against liquid securities is not recommended. 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.  There are two types of repo maturities: term and open pension. The U.S. bond market is between $2 trillion and $4 trillion. The European repo market is more than twice as high as at $9 trillion.
While the mechanics of a repo reverse involves the sale and then the repurchase of securities at a certain price and period, a reverse repo is indeed a guaranteed loan.
