Process of Deposit Creation in Banks Quiz: Money Creation

When a bank approves a loan, it credits the borrower's account with the loan amount rather than handing over physical cash. This simultaneously creates a new asset for the bank, the loan receivable, and a new liability, the deposit. This act of lending is how banks create new money in the economy, expanding the total money supply beyond the original base.

The answer is True. When a bank extends a loan, it credits the borrower's deposit account, creating a brand-new deposit. This new deposit adds to the total stock of money in circulation because it is a fresh claim on purchasing power that was not there before. Repaying a loan does the opposite, reducing deposits and contracting the money supply.

The reserve requirement sets the minimum share of deposits a bank must retain as reserves. The remainder can be lent out, which triggers further deposit creation elsewhere in the banking system. A lower reserve requirement allows more lending per deposit, amplifying the deposit creation process, while a higher requirement restrains how much new money banks can create.

Fractional reserve banking means that for every dollar deposited, banks retain only a small percentage as reserves and lend the rest. The borrower spends or deposits those lent funds, which then become reserves at another bank that can lend again. This chain of lending and redepositing is what allows the banking system to create a much larger total volume of deposits than the initial base money.

The answer is False. Each bank in the deposit creation chain is required to retain a fraction of every deposit as required reserves. Only the remaining portion is available to lend. It is this partial retention, not full lending, that limits how much each individual bank can lend and ultimately determines the total amount of deposits the banking system can create from a given initial deposit.

With a 10 percent reserve requirement, the bank must keep 100 dollars in reserve and can lend the remaining 900 dollars. The 900 dollars lent out will eventually be deposited elsewhere, where the receiving bank will keep 90 dollars in reserve and lend 810 dollars, continuing the process. This sequential lending across the system creates new deposits far exceeding the original 1,000 dollar deposit.

All four statements accurately describe deposit creation. An initial deposit enables lending of excess reserves, which generates new deposits elsewhere. Each subsequent round is smaller because reserves are retained at every stage. The reserve requirement caps the total expansion. And the overall outcome is that the banking system creates a money supply significantly larger than the original base money injected.

Deposit creation is a chain process because each loan generates a new deposit at another bank, which then lends a fraction of that deposit, generating another deposit, and so on. Each link in the chain is smaller than the last due to reserve retention. The process continues across the entire banking system until no excess reserves remain, resulting in a total expansion that is a multiple of the original deposit.

The answer is True. Due to fractional reserve banking, each deposit enables lending, which creates new deposits that enable further lending. This chain repeats throughout the banking system, expanding the total stock of deposits to a multiple of the original base money deposit. The size of this multiple depends on the reserve requirement, a lower reserve ratio leads to greater total deposit expansion.

Just as lending creates deposits, repaying loans destroys them. When a borrower repays a loan, the deposit used to make the repayment is extinguished, reducing the total money supply. This is the mirror image of the deposit creation process. Banks create money when they lend and destroy money when loans are repaid, making the total deposit base dynamic and responsive to borrowing activity.

The central bank sits at the foundation of deposit creation by controlling base money, the notes, coins, and reserves that commercial banks hold. By adjusting the quantity of base money and setting reserve requirements, the central bank influences how much lending and deposit creation the banking system can support. Monetary policy tools such as open market operations directly affect this base and thereby the capacity for deposit expansion.

The answer is False. Deposit creation occurs automatically through the normal lending decisions of commercial banks. When a bank approves a loan and credits a deposit account, it creates new money without needing individual authorization from the central bank. The central bank shapes the overall environment through reserve requirements and base money supply, but it does not approve each individual act of deposit creation.

Deposit creation is equivalent to money creation because new bank deposits are a form of money. Most of the money supply in a modern economy consists of bank deposits rather than physical currency. When banks make loans, they expand the total deposit base, increasing the overall quantity of money available for spending and investment, which is why commercial bank lending is central to understanding how the money supply grows.

A higher reserve requirement forces banks to retain more of each deposit, reducing the amount available for lending and shrinking the multiplier. Voluntary excess reserves have the same effect. Cash leakage, where borrowers hold cash instead of depositing funds, also limits the chain by removing money from the deposit creation cycle. A lower central bank rate does not directly limit deposit creation and may instead stimulate more borrowing.

The money multiplier equals one divided by the reserve requirement. With a 20 percent, or 0.20, reserve requirement, the multiplier is one divided by 0.20, which equals 5. This means that every one dollar of new base money deposited into the banking system can theoretically support up to five dollars of total deposits through successive rounds of lending and redepositing, assuming all funds are redeposited and no excess reserves are held.
