If The Reserve Requirement Is 20%, Initial New Deposits

if the reserve requirement is 20%, if initial new deposits are $100,000 what is the maximum amount of total loans that can be created by banks

If the reserve requirement is 20%, this means that banks must hold 20% of their deposits as reserves and can lend out the remaining 80%. When initial new deposits of $100,000 are made, the amount held as reserves is calculated as:

Reserves = Reserve Requirement x Initial Deposits = 20% x $100,000 = $20,000

The remaining amount that banks are eligible to lend out directly equals:

Loanable Funds = Initial Deposits - Reserves = $100,000 - $20,000 = $80,000

However, the maximum total amount of loans that can be created in the banking system involves the money multiplier effect. The money multiplier is the reciprocal of the reserve requirement, expressed as:

Money Multiplier = 1 / Reserve Requirement = 1 / 0.20 = 5

Therefore, the maximum total amount of deposits (including the initial deposit and all subsequent loans) that can be generated from the initial deposit is:

Total Potential Deposits = Initial Deposit x Money Multiplier = $100,000 x 5 = $500,000

To find the maximum amount of additional loans that can be created, subtract the initial deposits (which are already held) from this total:

Maximum Total Loans = Total Potential Deposits - Initial Deposits = $500,000 - $100,000 = $400,000

This calculation aligns with the concept that banks can support up to $400,000 in new loans with an initial deposit of $100,000 at a 20% reserve requirement. This leverages the money creation process, where banks lend out most of their deposits, and those loans subsequently become deposits in other banks, amplifying the initial deposit's impact on the economy.

The question of how much total loans can be created by banks based on initial deposits and reserve requirements is fundamental to understanding the mechanics of monetary policy and banking operations. This analysis involves the concepts of reserve ratios, the money multiplier, and the process of money creation within the banking system.

Reserve Requirements are regulations set by central banks, which specify the minimum amount of reserves a bank must hold against deposits. In this case, a 20% reserve requirement indicates that banks must retain 20% of their deposits in reserve and can lend out the remaining 80%. This ratio plays a crucial role in determining the extent to which banks can generate new loans, effectively controlling the money supply within the economy (Mishkin, 2015).

The initial deposit of $100,000 serves as the seed capital for the banking system; from this, the process of deposit expansion begins. Banks are legally required to keep 20% of this amount in reserve, which translates to $20,000. The remaining $80,000 in deposits is available for lending. When banks lend out this amount, the recipients deposit the funds into their accounts in the same or other banks, repeating the cycle. This cycle continues, with each subsequent deposit generating more loans, which ultimately expands the total money supply based on the initial deposit (Cecchetti & Schoenholtz, 2014).

The fundamental concept here is the money multiplier, which illustrates how an initial deposit can lead to a multiple expansion of the money supply. The multiplier is calculated as the reciprocal of the reserve requirement: with a 20% reserve ratio, the multiplier is 1/0.20, equaling 5. (Boyd & Smith, 2021). This means that the total potential deposits in the banking system can reach five times the initial deposit, assuming banks lend out all excess reserves and there are no withdrawals or leakages.

Applying this to the case at hand, the total potential deposit expansion from an initial $100,000 deposit is:

Total Deposits = Initial Deposit x Money Multiplier = $100,000 x 5 = $500,000.

Since the initial deposit is already part of this total, the additional loans generated through the process would be:

Additional Loans = Total Deposits - Initial Deposit = $500,000 - $100,000 = $400,000.

This is the maximum amount of new loans that can be created by the banking system starting from an initial deposit of $100,000 at a reserve requirement of 20%. It is important to emphasize that this theoretical maximum assumes perfect conditions—banks lend out all excess reserves, there are no cash withdrawals or reserves hold beyond the minimum, and that economic conditions permit such lending.

In reality, various factors can influence this potential, including bank lending policies, economic environments, regulatory constraints, and borrower demand. Nevertheless, this model provides vital insight into the mechanics of monetary policy and how central banks influence the money supply through reserve requirements and other tools.
