Rest and ABCP are both short-term credit instruments. In the case of ABCP, a company or group sells receivables to a bank which, in turn, expresses them in the form of commercial paper to its investors. Commercial paper is covered by the expected cash inflows on receivables. Deposits are very short-term secured loans that work much like this: a trader sells securities to investors, with the promise of buying them back at the same price plus a premium. The amount of the premium depends on the risk received. When repo transactions are settled by the Federal Open Market Committee of the Federal Reserve as part of open market operations, repo transactions add reserves to the banking system and then withdraw them after a certain period of time; Reverse-rests first remove reserves and then add them again. This instrument can also be used to stabilize interest rates and the Federal Reserve has used it to adjust the federal funds rate to the target rate.  From 2007 on, the shadow banking system experienced a sharp decline. The reason why this happened is little understood, but a popular theory is that many of the short-term funds received by shadow banks before the crisis had the form of retreat operations and that many of these deposits were secured by securitized mortgages as collateral. According to this view, the shadow banking system collapsed when MONEY MARKET funds and other lenders became concerned about the quality of the collateral, which supported Repos and withdrew their funding. In the United States, the most common type of repo is the tripartite agreement. A large commercial bank acts as an intermediary.
It negotiates an agreement between a financial institution that needs cash, usually a securities dealer or hedge fund, and another that has excess credit, such as an MMF.B. Repo transactions are short-term secured loans used by large financial institutions to obtain short-term financing, by mortgaging their assets for short-term loans or by earning interest, by lending cash that is backed by these assets. Central banks use these agreements to provide loans to large financial institutions and to control interest rates….
