The repurchase agreement (repo or PR) and the repurchase agreement (RRP) are two key instruments used by many large financial institutions, banks and some companies. These short-term agreements provide temporary lending opportunities that contribute to the financing of day-to-day operations. The Federal Reserve also uses the repo and auto-repo agreements as a method of controlling the money supply. When carried out by the Federal Reserve`s open market committee 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.  The Federal Reserve`s Open Market Committee (FOMC) has stated that it intends to use an overnight anti-reverse-repurchase (ON RRP) agreement as an additional policy instrument to control the key rate and keep it within the FOMC target range (to learn more about the Federal Reserve`s plans to normalize monetary policy). The Committee stated that it would only use and emigrate an ON-RRP mechanism to the extent necessary if it was no longer necessary to control the credit ratio. A reverse pension contract, or „reverse pension,“ is the purchase of securities with the agreement to sell them at a higher price at any given time. For the party that sells the guarantee (and agrees to buy it back in the future), it is a buy-back (RP) or repo contract; for the other end of the transaction (purchase of security and consent to the sale in the future), it is a reverse repurchase agreement (RRP) or Reverse Repo. 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. When the Federal Reserve makes an EIA overnight, it sells a guarantee to an eligible counterparty and agrees to repurchase the guarantee the next day.
