A final way banks raise funds in the money market is through repurchase agreements (RPs). An RP is a sale of securities with a simultaneous agreement by the seller to repurchase them at a later date. (For the lender—that is, the buyer of the securities in such a transaction—the agreement is often called a reverse RP.) In effect this agreement (when properly executed) is a short-term collateralized loan. Most RPs involve . government securities or securities issued by government-sponsored enterprises. Banks are active participants on the borrowing side of the RP market. .
