The Federal Reserve's Toolkit
- Describe the Fed's policy tools and identify which is used routinely
- Explain how interest on reserves sets a floor under the policy rate
- Distinguish the federal funds rate from the discount rate
Open market operations do the routine work
Open market operations — buying and selling government securities — are the Fed's everyday tool. Buying bonds pays banks in reserves, expanding the money supply and lowering the federal funds rate; selling does the reverse. The reason it is the preferred tool is practical: it can be done in any size, at any time, and reversed the next day, which no other tool allows.
The federal funds rate is a market rate the Fed targets
The federal funds rate is what banks charge each other for overnight loans of reserves. The Fed does not set it by decree; it announces a target and uses its tools to keep the market rate there. The discount rate is different — it is what the Fed itself charges banks that borrow directly from it, and it is set administratively above the funds target so that direct borrowing is a backstop rather than a first resort.
Interest on reserves sets a floor
The Fed pays banks interest on reserve balances held at the Fed. That rate is a risk-free return available to every bank, so no bank will lend to another bank for less — which makes it a floor under the federal funds rate. Raising it raises the whole structure of short-term rates without the Fed having to sell a single bond. This is how the Fed now moves rates in practice, and it works even when the banking system holds very large reserves.
Why the reserve requirement is not used
Changing the reserve requirement works — it directly changes the money multiplier — but it is a blunt instrument. A small change swings the money supply by a large multiple, it disrupts bank planning, and it cannot be fine-tuned. In practice it is rarely adjusted, and the United States reduced its requirement to zero in 2020. The exam still asks about its mechanics because the multiplier arithmetic is instructive, so know how it works while knowing it is not the working tool.
Inflation is running above target and the Fed wants to tighten. Describe two tools it could use and trace each through the money market to real output.
- 1.Tool 1: sell government securities. Banks pay with reserves, so the money supply shifts left.
- 2.Tool 2: raise the interest rate paid on reserve balances, making lending less attractive than holding reserves.
- 3.Either way the nominal federal funds rate rises.
- 4.Higher rates reduce interest-sensitive investment and consumption, shifting AD left.
- 5.Real GDP falls and the price level falls, easing the inflation.
The Fed does not "set" the federal funds rate directly and does not print money to fund the government. It targets a market rate using its balance sheet. An answer saying the Fed "prints money" or "sets interest rates by law" misdescribes the mechanism.
The Federal Reserve sells government securities on the open market. The effect is that the money supply:
The federal funds rate differs from the discount rate in that the federal funds rate is:
Paying interest on reserve balances held at the Fed puts a floor under short-term rates because:
When asked for a monetary policy action, name the specific tool and its direction — "the Fed buys government securities" rather than "the Fed uses expansionary policy". The rubric wants the action, not the label.
