Federal Reserve Tools, Money Supply, and Monetary Policy
This paper examines three interconnected topics in macroeconomics: whether credit cards and debit cards qualify as money, how Federal Reserve open market purchases affect the money supply, and the three primary monetary policy tools the Fed uses to influence real GDP. The paper clarifies that cards are financial instruments, not money itself, and corrects the misconception that open market purchases decrease the money supply. It then details how open market operations, the discount rate, and reserve requirements each work to expand or contract the money supply — and discusses potential downsides, including inflation, asset bubbles, and the propping up of economically unviable "zombie" firms and consumers.

What makes this paper effective
- The paper begins by tackling a common misconception — that credit and debit cards are money — and uses a clear definition of money to resolve the question before moving on.
- It explicitly identifies and corrects a false statement about Fed open market purchases, demonstrating critical engagement with course material rather than passive summary.
- The treatment of monetary policy tools is methodical: each tool is introduced, its mechanism explained step by step, and its broader economic consequences acknowledged, including potential negative effects like asset bubbles and zombie firms.
Key academic technique demonstrated
The paper demonstrates effective use of definitional grounding — establishing what money is before evaluating whether cards qualify — and then applies that framework consistently. The critical correction of the open market purchase statement shows the ability to evaluate claims against economic principles rather than simply restating them.
Structure breakdown
The paper is organized into three main topic blocks: (1) the nature of payment cards as financial instruments, (2) the corrected explanation of open market purchases, and (3) an extended discussion of the Fed's three monetary policy tools subdivided into focused subsections. It closes with a brief synthesis of expansionary policy's goals and risks. Citations are drawn from journalistic and institutional sources throughout.
Are Credit Cards and Debit Cards Money?
Credit cards and debit cards are not money; they are financial instruments that facilitate transactions in which money is exchanged. Both types of cards represent a convenient way to access and spend funds held in a bank account — or made available through a line of credit. Because they access different types of accounts, they function differently (Chand, n.d.).
First, what is money? Money is a medium of exchange, a unit of account, and a store of value (Beattie, 2022). It comes in various forms, such as cash, coins, or digital currency (Chand, n.d.). Debit cards are linked to a bank account; when a transaction is made using a debit card, funds are directly withdrawn from that account. Because the transaction draws on funds the cardholder already owns, a debit card can be thought of as an electronic form of cash — but the key point is that the money is the cardholder's own and is drawn directly from their account.
Credit cards, on the other hand, allow the cardholder to borrow money from the card issuer — usually a bank — to make a purchase. Using a credit card is essentially taking out a short-term loan that must be repaid later, often with interest if the balance is not paid in full by the due date.
In both cases, the cards themselves are not money. Rather, they are a means of accessing and using money held in accounts or obtained through borrowed funds.
