Loan Creation and Deposit Expansion Quiz

In modern banking, a loan is created by simply crediting the borrower's deposit account with the approved loan amount. This action simultaneously creates a new asset for the bank, the loan receivable, and a new liability, the deposit. No prior savings need to exist for this to happen. The bank effectively creates purchasing power by entering numbers into an account, which is the essence of deposit expansion through loan creation.

The answer is True. In modern economies, most money in circulation exists as bank deposits rather than physical currency. Because banks create new deposits every time they make a loan, commercial bank lending is the dominant driver of money supply growth. The broad money supply expands as banks extend more credit and contracts when loans are repaid, making private bank lending decisions central to monetary dynamics.

When a bank extends a loan and credits the borrower's account, its balance sheet expands symmetrically. The loan appears as a new asset because the bank holds a claim on the borrower for repayment. The credited deposit appears as a new liability because the bank owes that amount to the account holder. Both sides rise equally, maintaining the balance sheet identity while expanding the total size of the bank's financial position.

Deposit expansion is the system-wide multiplication of deposits that occurs when a single new loan creates a deposit, which is then redeposited, enabling another bank to make another loan, and so on. Each round creates a new, smaller deposit. The total expansion of deposits across all banks is a multiple of the original loan amount, determined by the reserve requirement and the degree to which funds remain within the banking system.

The answer is True. The deposit expansion chain depends on spent loan proceeds being redeposited in the banking system. When a borrower spends their loan and the payee deposits the funds at another bank, that bank receives new reserves. After meeting its reserve requirement, it can lend the excess, creating another deposit. This transmission of spending into new deposits at successive banks is what drives the multiplied expansion of total deposits.

Modern banking practice reverses the traditional savings-to-loans sequence. Rather than collecting savings first and then lending them out, banks create a new deposit at the moment a loan is approved. This is possible within a fractional reserve system because the bank's balance sheet expands to accommodate the new asset and liability simultaneously. Loans therefore generate deposits, not the reverse, which is a key insight of contemporary monetary theory.

Loan creation triggers deposit expansion across the system because each new deposit enables further lending. The total expansion exceeds the original loan amount due to the multiplier effect. The process terminates when all excess reserves are exhausted and no further lending is possible without violating reserve requirements. Each successive round produces a smaller, not larger, deposit because reserves are retained at every stage, making the third option incorrect.

When 10,000 dollars arrives at Bank B as a new deposit, Bank B records this as a liability. It must hold 10 percent, or 1,000 dollars, as required reserves and can lend out the remaining 9,000 dollars. If it does so, it creates a new deposit of 9,000 dollars elsewhere, and the chain continues. Each bank in the sequence lends 90 percent of its new deposit, progressively expanding total deposits across the system.

The answer is False. Deposit expansion works through lending to any borrower, whether households, businesses, or other institutions. When a borrower spends the loan proceeds, the recipient deposits the funds at a bank, regardless of who the original borrower was. The key requirement for the multiplier to operate is that spent funds are redeposited within the banking system, not that lending occurs between banks specifically.

The reserve requirement directly determines the fraction of each new deposit that must be retained rather than lent. A lower requirement means more of each deposit flows into new loans, accelerating the deposit expansion chain and producing a higher multiplier. A higher requirement slows the chain, as more is retained at each stage and less is lent forward. The reserve requirement is therefore the primary regulator of the deposit expansion process.

Loan creation and deposit destruction are mirror processes. When a borrower repays a loan, the repaid amount is used to extinguish both the loan asset and the associated deposit liability. The money supply contracts by the amount repaid, reversing the deposit expansion that occurred when the loan was first made. This symmetry means that the money supply is continually shaped by the net flow of new lending versus loan repayments across the entire banking system.

The answer is True. The money multiplier with a 5 percent reserve requirement equals one divided by 0.05, which is 20. An initial loan that creates a 1,000 dollar deposit can therefore theoretically support up to 20,000 dollars in total deposits across the system as the deposit expansion chain works through successive banks. This theoretical maximum assumes no cash leakage and no excess reserve holdings by any bank in the chain.

No single bank can multiply deposits on its own. The full deposit expansion requires that when one bank lends and creates a deposit, the borrower spends those funds, the recipient deposits them at another bank, and that bank then lends its excess. This sequence of spending, redepositing, and relending across the entire banking system is what produces the multiplied total. It is a collective, systemic outcome of individual bank decisions.

Loan creation directly expands the money supply by generating new deposits, while loan repayment contracts it. Both private bank lending behavior and central bank policies affecting the monetary base influence the total money supply. The claim that only physical currency counts is incorrect, as bank deposits created through lending constitute the majority of money in modern economies and are fully counted in measures of the broad money supply.

The deposit expansion multiplier depends on each round of lending generating a new deposit at some bank in the system. If all borrowers withdrew their loan proceeds as cash and held it outside the banking system, no new deposits would be created and no bank would receive new reserves to lend. The chain would be entirely broken, producing zero deposit expansion beyond the initial loan, which is the most extreme form of cash leakage that can occur.
