Reserve Requirement Definition

Reserve Requirement is the liquid cash amount in a proportion of its total deposit required to be kept either in the bank or deposited in the central bank. Therefore, the bank cannot access it for any business or economic activity.

It is mandated by central banks worldwide for their member banks to regulate the safety cash held by the banks. This cash reserve serves many different purposes in different economies. For example, the Central bank of the United States is the Federal Bank, which holds authority on this requirement in the United States. The People’s Bank of China functions similarly for Chinese banks.

Components of Reserve Requirement

Reserve Requirement is a function of Net Demand and Time Liabilities (NDTL). NDTL is based on current deposits, saving deposits, term deposits, and other liabilities. This is also adjusted for the deposits from other banks. The formula for NDTL becomes:

NDTL = demand liabilities + time liabilities + other demand and time liabilities – deposits with other banks

The calculation can be done by using Net demand and time liabilities.

Examples of Reserve Requirements

Below are the given examples to understand its calculation in a better manner.

Example #1

Suppose that the Federal Reserve requires a bank named ABL in the United States to maintain a 9.2% cash reserve. The bank declares its net demand and time liabilities at $100 million. What is the amount of reserve the bank will put in the Federal reserve?

Solution:

Since the federal reserve has a 9.2% regulation on cash reserves, it will apply to the net demand and time liabilities of the bank ABL. Therefore, the bank will maintain 9.2% of its NDTL of $100 million in reserve.

Cash Reserve against NDTL

  • =$100*9.2%=$9.2

Thus, it will maintain $9.2 million in the Federal Reserve vaults.

Example #2

A bank in Mexico, Smith and Sons Limited, has been mandated a reserve requirement of 7.5% of its net demand and time liabilities (NDTL). If it has the following liabilities (see table) on its balance sheet and an 80% can be attributed to the NDTL, do the calculation to get the amount it should be maintaining for reserve requirement?

All figures are in US dollars.

Solution

The table above can deduce the total liabilities the bank has on its balance sheet. The reserve requirement is a function of the net demand and time liabilities (NDTL), and thus, the latter can be obtained as a percentage of the total liabilities.

Total Liabilities & Net Demand and Time Liabilities

  • Thus, total liabilities = $23 mn + $30 mn + $12 mn = $65 mn.

NDTL = 80% of total liabilities which is 80% of $65 mn

Reserve requirement = 5% of NDTL.

Amount Reserves

  • =$3.9

So, the number of reserves the bank has to make with Mexico’s central bank = $3.9 mn.

Advantages

  • For a long time in banking history, reserve requirements helped Central banks regulate the circulation of money. It is now deemed helpful in keeping interest rates (lending rates) under check. Central banks do not necessarily mandate these rates but influence or impact them.It also guides other rates which the banks use among themselves. For instance, the LIBORLIBORLIBOR Rate (London Interbank Offer) is an estimated rate calculated by averaging out the current interest rate charged by prominent central banks in London as a benchmark rate for financial markets domestically and internationally, where it varies on a day-to-day basis inclined to specific market conditions.read more – London Interbank Offered Rate.It is also a measure to keep liquidity in the system under the scanner.It can also be used as a tool for fighting inflation.

Limitations

  • The cash reserve ratio does not account for short-term funds and other marketable securitiesMarketable SecuritiesMarketable securities are liquid assets that can be converted into cash quickly and are classified as current assets on a company’s balance sheet. Commercial Paper, Treasury notes, and other money market instruments are included in it.read more considered highly liquid. Hence, it does not present a true picture of a bank’s liquidity.An ill-managed reserve can cause a slowdown in the economy and haphazard measures by financial institutions.Most economists in the modern era disagree with the notion of reserve requirement as controlling money circulation. They opine that with growing functionalities in the banking space, such requirements have a lesser role in regulating money circulation.

Disadvantages

  • A continuous increase or decrease in reserve requirements may cause the spirit of investors to die down. They sometimes become critical in investor circles.These requirements are changed only when needed stringently because they can be expensive to implement.

Important Points

  • If the reserve requirement from the Central banks is high, the member banks make fewer profits because they have a higher amount in the custody of Central banks. Vice versa, the profits are high if this requirement is less.Banks borrow funds from the Federal Reserve as well as from each other. The funds borrowed and lent among the banks are known as Federal funds. And the interest rate that is charged is called the Fed funds rate.Any financial institution that holds amounts over the required reserves is said to have excess reserves.

Conclusion

Reserve requirements may not always serve its purpose. As could be seen during the financial crisisThe Financial CrisisThe term “financial crisis” refers to a situation in which the market’s key financial assets experience a sharp decline in market value over a relatively short period of time, or when leading businesses are unable to pay their enormous debt, or when financing institutions face a liquidity crunch and are unable to return money to depositors, all of which cause panic in the capital markets and among investors.read more of 2008-09, the lower interest rates and lesser requirements could not manifest into expansionary tactics as intended. Instead, it was because of general distrust that could not be compensated through these requirements.

Countries like the United States, India, and Japan are mandated by their Central banks – the Federal Reserve of the United States, Reserve Bank of India, and Bank of Japan, respectively, for reserve requirements. For a liability of more than $124.2 million, the US Federal Reserve System requires banks to put aside 10%, which is effective from Jan 17, 2019. The lower limit in the United States is $2 million, below which financial institutions need not abide by such requirements.

In the past two decades, the Reserve Bank of India has averaged 5.41% on the Cash reserve requirement. There are countries where there is no requirement to keep cash reserves. For example, Hong Kong, the United Kingdom, and Australia are free from such requirements.
