# Reserve Requirement — AP Gov Definition & Exam Guide

## Definition

The reserve requirement is a Federal Reserve rule requiring banks to keep a set percentage of deposits as non-lendable cash, letting the Fed shrink or grow the money supply. In AP Gov, it's a textbook example of a bureaucratic agency using discretionary rulemaking authority delegated by Congress (Topic 2.13).

## What It Is

The reserve requirement is a regulation set by the [Federal Reserve](/ap-gov/key-terms/federal-reserve "fv-autolink") (created by [Congress](/ap-gov/unit-1/principles-american-government/study-guide/BXlQvFOiaKwhntWYhgKP "fv-autolink") in the Federal Reserve Act of 1913) that tells commercial banks what percentage of customer deposits they must keep on hand as cash or parked at the central bank, rather than loaning out. Raise the percentage and banks can lend less, so the money supply tightens. Lower it and banks can lend more, so credit flows and the economy gets a boost.

Here's why this lives in [AP Gov](/ap-gov "fv-autolink") and not just econ class. Congress never votes on the reserve requirement. It delegated that power to the Fed, and unelected officials at the Fed adjust it using their own expert judgment. That makes the reserve requirement a perfect concrete example of **delegated discretionary authority**, the idea at the heart of Topic 2.13. Congress writes a broad law, and a bureaucratic agency fills in the details with rules that carry the force of law.

## Why It Matters

This term supports learning objective **AP Gov 2.13.A**: explain how the [federal bureaucracy](/ap-gov/key-terms/federal-bureaucracy "fv-autolink") uses [delegated discretionary authority](/ap-gov/unit-2/discretionary-rule-making-authority/study-guide/YxmZPw9AwHcHZWz5yggD "fv-autolink") for rulemaking and implementation. The CED's essential knowledge says agencies use discretion delegated by Congress to interpret and implement policy, and the reserve requirement is one of the cleanest examples you can cite. The Fed doesn't ask Congress for permission every time it adjusts banking rules; it acts on the authority Congress handed it back in 1913. When an FRQ or MCQ asks how the bureaucracy makes policy without passing a law, the Fed adjusting the reserve requirement is exactly the kind of evidence that works. It also shows why delegation is controversial: an enormously powerful economic decision is made by appointed experts, not elected representatives.

## Connections

### [Delegating Discretionary Authority (Unit 2)](/ap-gov/key-terms/delegating-discretionary-authority)

The reserve requirement only exists because Congress delegated monetary power to the Fed. It's the 'after' picture of delegation: a broad 1913 statute becomes a specific, enforceable percentage set by bureaucrats decades later.

### [Bureaucratic agency (Unit 2)](/ap-gov/key-terms/bureaucratic-agency)

The Federal Reserve is an independent agency, meaning it's insulated from direct presidential control. That independence is the whole point. Monetary decisions like the reserve requirement are supposed to follow economics, not [election cycles](/ap-gov/unit-5/modern-campaigns/study-guide/bDZVglv4xI4UVWT2BM7Q "fv-autolink").

### [Environmental Protection Agency (EPA) (Unit 2)](/ap-gov/key-terms/environmental-protection-agency-epa)

Same playbook, different policy area. The EPA sets emissions standards the way the Fed sets reserve requirements. Both turn vague congressional [mandates](/ap-gov/unit-1/relationship-between-states-federal-government/study-guide/kp9bW6CAUn0T0GiGqDUO "fv-autolink") into specific, binding rules, which is what the CED means by rulemaking authority.

### [Public Policy (Unit 2)](/ap-gov/key-terms/public-policy)

Changing the reserve requirement is [monetary policy](/ap-gov/key-terms/monetary-policy "fv-autolink") made entirely inside the bureaucracy. It shows that public policy isn't just laws passed by Congress; some of the most consequential policy happens through agency rules.

## On the AP Exam

You won't be asked to calculate anything with the reserve requirement. AP Gov isn't AP Macro. Instead, it shows up as evidence and as an example. No released FRQ has used the term verbatim, but it's tailor-made for the Concept Application FRQ and for Argument Essay points about bureaucratic power. Multiple-choice stems in this area typically describe an agency setting a rule (like a bank reserve percentage) and ask you to identify it as an exercise of delegated discretionary or rulemaking authority. The move you need to make is connecting the specific rule back to the bigger idea: Congress delegates, agencies fill in the details, and those details have the force of law. Bonus points if you can explain the accountability tension, since unelected Fed officials making major economic policy raises questions about democratic control of the bureaucracy.

## reserve requirement vs Fiscal policy

The reserve requirement is a monetary policy tool, controlled by the Federal Reserve (a bureaucratic agency). Fiscal policy means taxing and spending, which only Congress and the president control through the legislative process. If the question involves the Fed adjusting bank rules or interest rates, that's monetary policy made through bureaucratic discretion. If it involves a budget, a tax cut, or a spending bill, that's fiscal policy made through elected branches. Mixing these up is one of the most common errors on Unit 2 and policymaking questions.

## Key Takeaways

- The reserve requirement is the percentage of customer deposits the Federal Reserve requires banks to hold as cash instead of lending out.
- Raising the reserve requirement shrinks the money supply by limiting lending, while lowering it expands credit and stimulates the economy.
- In AP Gov, the reserve requirement matters as an example of delegated discretionary authority under Topic 2.13, because Congress gave the Fed this power in the Federal Reserve Act of 1913 and the Fed exercises it without new legislation.
- The reserve requirement is monetary policy set by an independent agency, not fiscal policy, which is the taxing and spending controlled by Congress and the president.
- The Fed's power here illustrates the core debate about the bureaucracy: unelected experts making major policy is efficient but raises democratic accountability concerns.

## FAQs

### What is the reserve requirement in AP Gov?

It's the Federal Reserve's rule requiring banks to keep a set percentage of deposits as non-lendable cash. In AP Gov, it's used as an example of a bureaucratic agency exercising rulemaking authority delegated by Congress (Topic 2.13).

### Does Congress set the reserve requirement?

No. Congress created the Federal Reserve in 1913 and delegated this power to it, but the Fed itself sets and adjusts the reserve requirement. That gap between who wrote the law and who makes the rule is exactly what 'delegated discretionary authority' means.

### Is the reserve requirement fiscal policy or monetary policy?

Monetary policy. It controls the money supply through the banking system and is set by the Fed. Fiscal policy is taxing and spending, which goes through Congress and the president. The exam loves testing this distinction.

### What happens when the Fed raises the reserve requirement?

Banks must hold more cash and can lend less, so the money supply tightens and credit gets harder to obtain. Lowering the requirement does the opposite, freeing banks to lend more and stimulating economic activity.

### Why is the reserve requirement an example of bureaucratic discretion?

Because the Federal Reserve Act of 1913 gave the Fed broad authority over banking, and Fed officials use their own judgment to decide the specific percentage. No new law is needed, which is the definition of discretionary rulemaking under learning objective AP Gov 2.13.A.
