The correct answer is Federal Funds Rate
The interest rate at which a country's central bank lends money to domestic banks, frequently in the form of extremely short-term loans, is known as the "bank rate." A technique by which central banks influence economic activity is through the management of the bank rate. By reducing the cost of borrowing money, lower bank rates can encourage economic growth, and higher bank rates can restrain it when inflation is out of control.
In the US, the bank rate is also referred to as the discount rate. The Board of Governors of the Federal Reserve System determines the discount rate and the minimum reserves needed by banks in the United States.
