Final answer:
The discount rate is the interest charged by the Federal Reserve to banks, and is different from the federal funds rate, which is targeted by the Fed for monetary policy. Banks borrow from the Fed at the discount rate and lend to each other at the prime rate. These rates, when close to zero, limit central bank options to stimulate lending.
Step-by-step explanation:
The discount rate is the rate of interest charged to commercial banks and other depository institutions on loans they receive from the Federal Reserve.
This rate is set by the regional Federal Reserve Banks and is typically higher than the federal funds rate, which is the central target rate used by the Federal Reserve for its monetary policy. The federal funds rate was 5% in 2007, but dramatically declined to 0.16% by 2009 due to the recession.
If the discount rate were close to zero, it means that the central bank's ability to encourage lending through lower rates is limited. During such scenarios, other monetary policy tools are often used.
The Fed offers three types of discount window programs: primary credit, secondary credit, and seasonal credit, each with its own interest rate. Primary credit is offered to banks in sound financial condition, secondary credit is available to banks that are not eligible for primary credit, and seasonal credit is for small banks with seasonal needs. All discount window loans must be fully secured.
Banks also lend money to each other based on the prime rate, which is typically three percentage points above the Federal Reserve's rate to banks. If the Fed's rate is 1%, the prime rate would likely be at 4%. These interest rates are crucial for banks as they make profits by lending at higher rates than the rates they pay to borrow, such as the rate from the Federal Reserve.
Since 1995, the Fed has established its target federal funds rate in advance to guide open market operations, affecting the interest rates across the banking system. Changes in the federal funds target rate ripple through to various credit products and influence the overall economy.
