Reverse Repo (RRP)
The Fed's overnight reverse repurchase facility — where money funds park excess cash, providing a floor for short-term rates.
Definition
Through the RRP, the Fed takes overnight cash from counterparties (mostly money market funds) and posts Treasuries as collateral. The RRP rate sets the effective floor on short-term funding markets.
RRP balances act as a system-liquidity indicator: large balances mean abundant reserves; rapid drawdown signals reserves becoming scarce.
RRP here is the Federal Reserve facility, not a currency. If you searched "RRP currency", the term usually refers to this facility's cash balances, measured in U.S. dollars.
