Money as a means of payment and thus a lubricant that facilitates exchange. Irrespective of the form of money, in any economy, money performs three primary functions – a medium of exchange, a unit of account, and a store of value. Money as a medium of exchange may be used for any transactions wherein goods or services are purchased or sold. Money as a unit of account can be used to value goods or services and express it in monetary terms. Money can also be stored or conserved for future purposes. In the real world, however, money provides monetary services along with tangible remuneration. It is for this reason that money must have a relationship with the activities that economic entities pursue. Money can, therefore, be defined for policy purposes as a set of liquid financial assets, the variation in the stock of which could impact aggregate economic activity. Economic stability requires that the supply of money at any time should to be maintained at an optimum level. A pre-requisite for achieving this is to accurately estimate the stock of money supply on a regular basis and appropriately regulate it in accordance with the monetary requirements of the country. In this unit, we shall look into various aspects related to the supply of money.

M3 = M1 + Time deposits with the banking system. M2 = M1 + Savings deposits of post office savings banks. M1 = Currency with public + Demand deposits with the Banking system (savings account, current account). Broad money (M3) includes currency, deposits with an agreed maturity of up to two years, deposits redeemable at notice of up to three months and repurchase agreements, money market fund shares/units, and debt securities up to two years The term ‘public’ is defined to include all economic units (households, firms, and institutions) except the producers of money (i.e. the government and the banking system). The government, in this context, includes the central government and all state governments and local bodies; and the banking system means the Reserve Bank of India and all the banks that accept demand deposits (i.e. deposits from which money can be withdrawn by cheque mainly CASA deposits). The word ‘public’ is inclusive of all local authorities, non-banking financial institutions, and non-departmental public-sector undertakings, foreign central banks and governments and the International Monetary Fund which holds a part of Indian money in India in the form of deposits with the RBI. In other words, while discussing the definition of ‘supply of money’ and the standard measures of money, interbank deposits and money held by the government and the banking system are not included. 2.2 RATIONALE OF MEASURING MONEY SUPPLY The empirical analysis of the money supply is important for two reasons: 1. It facilitates analysis of monetary developments in order to provide a deeper understanding of the causes of money growth. © The Institute of Chartered Accountants of India  1.25 MONEY MARKET 8.25 2. It is essential from a monetary policy perspective as it provides a framework to evaluate whether the stock of money in the economy is consistent with the standards for price stability and to understand the nature of deviations from this standard. The central banks all over the world adopt monetary policy to stabilise price level and GDP growth by directly controlling the supply of money. This is achieved mainly by managing the quantity of monetary base. The success of monetary policy depends to a large extent on the controllability of the monetary base and the money supply. 2.3 THE SOURCES OF MONEY SUPPLY The supply of money in the economy depends on: (a) the decision of the central bank based on the authority conferred on it, and (b) the supply responses of the commercial banking system of the country to the changes in policy variables initiated by the central bank to influence the total money supply in the economy. Money either has intrinsic value or represents title to commodities that have intrinsic value or title to other debt instruments. In modern economies, the currency is a form of money that is issued exclusively by the sovereign (or a central bank as its representative) and is legal tender. Paper currency is such a representative money, and it is essentially a debt instrument. It is a liability of the issuing central bank (and sovereign) and an asset of the holding public. The central banks of all countries are empowered to issue currency and, therefore, the central bank is the primary source of money supply in all countries. In effect, high powered money issued by monetary authorities is the source of all other forms of money. The currency issued by the central bank is ‘fiat money’ and is backed by supporting reserves and its value is guaranteed by the government. The currency issued by the central bank is, in fact, a liability of the central bank and the government. Therefore, in principle, it must be backed by an equal value of assets mainly consisting of gold and foreign exchange reserves. In practice, however, most countries have adopted a ‘minimum reserve system’ wherein the central bank is empowered to issue currency to any extent by keeping only a certain minimum reserve of gold and foreign securities. The second major source of money supply is the banking system of the country. The total supply of money in the economy is also determined by the extent of credit created by the commercial banks in the country. Banks create money supply in the process of borrowing and lending transactions with the public. Money so created by the commercial banks is called 'credit money’. The high-powered money and the credit money broadly constitute the most © The Institute of Chartered Accountants of India.26 8.26 BUSINESS ECONOMICS common measure of money supply, or the total money stock of a country. (For a brief note on the process of creation of credit money, refer to Box 1, end of this chapter). With the developments in the economy and the evolution of the payments system, the form and functions of money has changed over time, and it will continue to influence the future course of currency. The concept of money has experienced evolution from Commodity to Metallic Currency to Paper Currency to Digital Currency. The changing features of money a re defining new financial landscape of the economy. Further, with the advent of cutting-edge technologies, digitalization of money is the next milestone in the monetary history. Advancement in technology has made it possible for the development of new form of money viz. Central Bank Digital Currencies (CBDCs). Recent innovations in technology-based payments solutions have led central banks around the globe to explore the potential benefits and risks of issuing a CBDC so as to maintain the continuum with the current trend in innovations. RBI has also been exploring the pros and cons of introduction of CBDCs for some time and is currently engaged in working towards a phased implementation strategy, going step by step through various stages of pilots followed by the final launch, and simultaneously examining use cases for the issuance of its own CBDC (Digital Rupee (e₹)), with minimal or no disruption to the financial system. Currently, we are at the forefront of a watershed movement in the evolution of currency that will decisively change the very nature of money and its functions. Reserve Bank broadly defines CBDC as the legal tender issued by a central bank in a digital form. It is akin to sovereign paper currency but takes a different form, exchangeable at par with the existing currency and shall be accepted as a medium of payment, legal tender and a safe store of value. CBDCs would appear as liability on a central bank’s balance sheet. The Crypto currencies face significant legislative uncertainties and are not legally recognized in India as currency. Hence, these are not categorized as money. In a massive development for crypto traders in India, the Reserve Bank of India (RBI) has said that banks or other financial entities cannot cite RBI’s 2018 order that barred them from dealing with virtual cryptocurrencies. 2.4 MEASUREMENT OF MONEY SUPPLY There is virtually a profusion of different types of money, especially credit money, and this makes measurement of money supply a difficult task. Different countries follow different practices in measuring money supply. The measures of money supply vary from country to country, from time to time and from purpose to purpose. Reference to such different measures is beyond the scope of this unit. Just as other countries do; a range of monetary and liquidity © The Institute of Chartered Accountants of India  1.27 MONEY MARKET 8.27 measures are compiled and published by the RBI. Money supply will change if the magnitude of any of its constituents changes. In this unit, we shall be concentrating on the Indian case only and in the following discussion, we shall focus on the alternative measures of money supply prepared and published periodically by the Reserve Bank of India. Since July 1935, the Reserve Bank of India has been compiling and disseminating monetary statistics. Till 1967-68, the RBI used to publish only a single ‘narrow measure of money supply’ (M1) defined as the sum of currency and demand deposits held by the public. From 1967-68, a 'broader' measure of money supply, called 'aggregate monetary resources' (AMR) was additionally published by the RBI. From April 1977, following the recommendations of the Second Working Group on Money Supply (SWG), the RBI has been publishing data on four alternative measures of money supply denoted by M1, M2, M3 and M4 besides the reserve money. The respective empirical definitions of these measures are given below: M1 = Currency notes and coins with the people + demand deposits with the banking system (Current and Saving deposit accounts) + other deposits with the RBI. M2 = M1 + savings deposits with post office savings banks. M3 = M1 + time deposits with the banking system. M4 = M3 + total deposits with the Post Office Savings Organization (excluding National Savings Certificates). 2.5 DETERMINANTS OF MONEY SUPPLY There are two alternate theories in respect of determination of money supply. According to the first view, money supply is determined exogenously by the central bank. The second view holds that the money supply is determined endogenously by changes in the economic activities which affect people’s desire to hold currency relative to deposits, rate of interest, etc. The current practice is to explain the determinants of money supply based on ‘money multiplier approach’ which focuses on the relation between the money stock and money supply in terms of the monetary base or high-powered money. The monetary base is the sum of currency in circulation and bank reserves. This approach holds that total supply of nominal money in the economy is determined by the joint behaviour of the central bank, the commercial banks and the public. Before we discuss the determinants of money supply, it is necessary that we know the concept of money multiplier. © The Institute of Chartered Accountants of India.28 8.28 BUSINESS ECONOMICS 2.6 THE CONCEPT OF MONEY MULTIPLIER The money created by the Reserve Bank of India is the monetary base, also known as high- powered money. Banks create money by making loans. A bank loans or invests its excess reserves to earn more interest. A one-rupee increase in the monetary base causes the money supply to increase by more than one rupee. The increase in the money supply is the money multiplier. The money supply is defined as Money is either currency held by the public or bank deposits: M = C + D. M = m X MB Where M is the money supply, m is the money multiplier and MB is the monetary base or high-powered money. From the above equation, we can derive the money multiplier (m) as Money supply Money Multiplier (m)= … Monetary base Money multiplier m is defined as a ratio that relates the changes in the money supply to a given change in the monetary base. It is the ratio of the stock of money to the stock of high - powered money. For instance, if there is an injection of Rs.100 Cr through an open market operation by the central bank of the country and if it leads to an increment of Rs.500 Cr. of final money supply, then the money multiplier is said to be 5. Hence, the multiplier indicates the change in monetary base which is transformed into money supply. The multiplier indicates what multiple of the monetary base is transformed into money supply. In other words, money and high-powered money are related by the money multiplier. We make two simplifying assumptions as follows; Banks never hold excess reserves. Individuals and non-bank corporations never hold currency. What determines the size of the money multiplier? The money multiplier is the reciprocal of the reserve ratio. Deposits, unlike currency held by people, keep only a fraction of the high - powered money in reserves and the rest is lent out and culminate in money creation. If R is the reserve ratio in a country for all commercial banks, then each unit of (say Rupee) money reserves generates 1/R money. 1 Therefore, for any value of R, the Money Multiplier is 𝑅 © The Institute of Chartered Accountants of India  1.29 MONEY MARKET 8.29 For example, if R =10%, the value of money multiplier will be 10. If the reserve ratio is only 5 %, then money multiplier is 20. Thus, the higher the reserve ratio, the less of each deposit banks loan out, and the smaller the money multiplier. If some portion of the increase in high-powered money finds its way into currency, this portion does not undergo multiple deposit expansion. The size of the money multiplier is reduced when funds are held as cash rather than as demand deposits. In other words, as a rule, an increase in the monetary base that goes into currency is not multiplied, whereas an increase in monetary base that goes into supporting deposits is multiplied. 2.7 THE MONEY MULTIPLIER APPROACH TO SUPPLY OF MONEY The money multiplier approach to money supply propounded by Milton Friedman and Anna Schwartz, (1963) considers three factors as immediate determinants of money supply, namely: (a) the stock of high-powered money (H) (b) the ratio of reserves to deposits or reserve-ratio r = {Reserves/Deposits R/D} and (c) the ratio of currency to deposits, or currency-deposit ratio c={C/D} You may note that these represent the behaviour of the central bank, behaviour of the commercial banks and the behaviour of the general public respectively. We shall now describe how each of the above contributes to the determination of aggregate money supply in an economy. a) The Behaviour of the Central Bank The behaviour of the central bank which controls the issue of currency is reflected in the supply of the nominal high-powered money. Money stock is determined by the money multiplier and the monetary base (H) is controlled by the monetary authority. If the behaviour of the public and the commercial banks remains unchanged over time, the total supply of nominal money in the economy will vary directly with the supply of the nominal high-powered money issued by the central bank. b) The Behaviour of Commercial Banks By creating credit, the commercial banks determine the total amount of nominal demand deposits. The behaviour of the commercial banks in the economy is reflected in the ratio of their cash reserves to deposits known as the ‘reserve ratio’. If the required reserve ratio on demand deposits increases while all the other variables remain the same, more reserves would be needed. This implies that banks must contract their loans, causing a decline in deposits and hence in the money supply. If the required reserve ratio falls, there will be greater © The Institute of Chartered Accountants of India.30 8.30 BUSINESS ECONOMICS expansions of deposits because the same level of reserves can now support more deposits and the money supply will increase. To sum up, smaller the reserve ratio larger will be the money multiplier. In actual practice, however, the commercial banks keep only the required fraction of their total deposits in the form of cash reserves. However, for the commercial banking system as a whole, the actual reserves ratio may be greater than the required reserve ratio since the banks keep a higher than the statutorily required percentage of their deposits in the form of cash reserves as a buffer against unexpected events requiring cash. The excess reserves (ER) which are funds that a bank keeps back beyond what is required by regulation form a very important determinant of money supply. ‘Excess reserves’ are the difference between total reserves (TR) and required reserves (RR). Therefore, ER=TR -RR. If total reserves are Rs 800 billion, whereas the required reserves are Rs 600billion, then the excess reserves are Rs 200 billion. We know that the cost to a bank while holding excess reserves is in terms of its opportunity cost, i.e. the interest that could have been earned on loans or securities if the bank had chosen to invest in them instead of excess reserves. If interest rate increases, it means that the opportunity cost of holding excess reserves rises because the banks have to sacrifice possible higher earnings and hence the desired ratio of excess reserves to deposits falls. Conversely, a decrease in interest rate will reduce the opportunity cost of excess reserves, and excess reserves will rise. Therefore, we conclude that the banking system's excess reserves ratio r is negatively related to the market interest rate. If banks fear that deposit outflows are likely to increase (that is, if expected deposit outflows increase), they will want more assurance against this possibility and will increase the excess reserves ratio. Conversely, a decline in expected deposit outflows will reduce the benefit of holding excess reserves and excess reserves will fall. As we know, money is mostly held in the form of deposits with commercial banks. Therefore, money supply may become subject to ‘shocks’ on account of behaviour of commercial banks which may present variations overtime either cyclically and more permanently. For instance, in times of financial crises, banks may be unwilling to lend to the small and medium scale industries who may become credit constrained facing a higher risk premia on their borrowings. The rising interest rates on bank credit to the commercial sector reflecting higher risk premia can co-exist with the lowering of policy rates by the central bank. The lower credit demand can lead to a sharp deceleration in monetary growth at a time when the central bank pursues an easy monetary policy. (Refer Box *1 below). © The Institute of Chartered Accountants of India  1.31 MONEY MARKET 8.31 c) The Behaviour of the Public As we know, demand deposits undergo multiple expansions while currency in your hands does not. Hence, when bank deposits are being converted into currency, banks can create only les s credit money. The overall level of multiple expansion declines, and therefore, money multiplier also falls. Hence, we conclude that money multiplier and the money supply are negatively related to the currency ratio c. The currency-deposit ratio (c) represents the degree of adoption of banking habits by the people. This is related to the level of economic activities or the GDP growth and is influenced by the degree of financial sophistication in terms of ease and access to financial services, availability of a richer array of liquid financial assets, financial innovations, institutional changes etc. The smaller the currency-deposit ratio, the larger would be the money multiplier. This is because a smaller proportion of high powered money is being used as currency and therefore, a larger proportion is available to be reserves which get transformed into money. The time deposit-demand deposit ratio i.e. how much money is kept as time deposits compared to demand deposits, also has an important implication for the money multiplier and, hence for the money stock in the economy. An increase in TD/DD ratio means that greater availability of free reserves and consequent enlargement of volume of multiple deposit expansion and monetary expansion. To summarise the money multiplier approach, the size of the money multiplier is determined by the required reserve ratio (r) at the central bank, the excess reserve ratio (e ) of commercial banks and the currency ratio (c) of the public. The lower these ratios are, the larger the money multiplier is. In other words, the money supply is determined by high powered money (H) and the money multiplier (m) and varies directly with changes in the monetary base, and inversely with the currency and reserve ratios. Although these three variables do not completely explain changes in the nominal money supply, nevertheless they serve as useful devices for analysing such changes. Consequently, these variables are designated as the ‘proximate determinants’ of the nominal money supply in the economy. We may now rewrite the money multiplier including the above variables. M = C+D (1) H = C+ reserves (2) Where C is currency and D is deposits which are assumed to be demand deposits. We summarise the behaviour of the public, banks and the central bank by three variables namely, currency-deposit ratio c= C/D, reserve-ratio r= Reserves/D, and the stock of high-powered money (H) © The Institute of Chartered Accountants of India.32 8.32 BUSINESS ECONOMICS Rewriting equation (1) and (2) above as M = (c+1) D, H = (c+ r) D 1+c M= xH=mxH r+c 1+c m= r+c When there are excess reserves, the money multiplier m is expressed as 1+c m= r+e+ c 1+c Money Supply M = xH r+e+ c The money multiplier is a function of: (a) the currency ratio set by depositors c which depends on the behaviour of the public (b) excess reserves ratio set by banks e, and (c) the required reserve ratio set by the central bank r, which depends on prescribed CRR and the balances necessary to meet settlement obligations. A simple example will explain the concept Numerical Illustration (a) In Gladys land, r = 10%= 0.10 Currency = 400 billion Deposits = 800 billion Excess Reserves = 0.8 billion = 800 million Money Supply is M = Currency + Deposits = 1200 billion c = C/D = 400 billion/800 billion = 0.5 or depositors hold 50 percent of their money as currency e= 0.8 billion /800 billion = 0.001 or banks hold 0.1% of their deposits as excess reserves. 1+c Multiplier m= r+e+ c © The Institute of Chartered Accountants of India  1.33 MONEY MARKET 8.33 = 1+0.5/ 0.1+0.001+0.5 = 1.5/ 0. 601 =2.5 Therefore, a 1 unit increase in H leads to a 2.50 units increase in M. The simple deposit multiplier in this example would be 1/r= 1/0.1=10 The difference is due to inclusion of currency and excess reserves in calculating the multiplier. (b) If the reserve ratio is increased to 15 percent, the value of the money multiplier will be, = 1+0.5/ 0.15+0.001+0.5 = 1.5/ 0. 651 =2.3 Obviously, r and m are negatively related: m falls when r rises, and m rises when r falls. The reason is that less multiple deposit creation can occur when r rises, while more multiple deposit creation can occur when r falls. 2.8 MONETARY POLICY AND MONEY SUPPLY If the central bank of a country wants to stimulate economic activity it does so by infusing liquidity into the system. Let us take the example of open market operations (OMO) by central banks. Purchase of government securities injects high powered money (monetary base) into the system. Assuming that banks do not hold excess reserves and people do not hold more currency than before, and also that there is demand for loans from businesses, the credit creation process by the banking system in the country will create money to the tune of 1 ∆Money supply = X ∆ Reserves R The effect of an open market sale is very similar to that of open market purchase, but in the opposite direction. In other words, an open market purchase by central bank will reduce the reserves and thereby reduce the money supply. Is it possible that the value of money multiplier is zero? It may happen when the interest rates are too low and the banks prefer to hold the newly injected reserves as excess reserves with no risk attached to it. 2.9 EFFECT OF GOVERNMENT EXPENDITURE ON MONEY SUPPLY Whenever the central and the state governments’ cash balances fall short of the minimum requirement, they are eligible to avail of a facility called Ways and Means Advances (WMA)/overdraft (OD) facility. When the Reserve Bank of India lends to the governments © The Institute of Chartered Accountants of India.34 8.34 BUSINESS ECONOMICS under WMA /OD, it results in the generation of excess reserves (i.e., excess balances of commercial banks with the Reserve Bank). This happens because when government incurs expenditure, it involves debiting the government balances with the Reserve Bank and cre diting the receiver (for e.g., salary account of government employee) account with the commercial bank. The excess reserves thus created can potentially lead to an increase in money supply through the money multiplier process. The Credit Multiplier The Credit Multiplier also referred to as the deposit multiplier or the deposit expansion multiplier, describes the amount of additional money created by commercial bank through the process of lending the available money it has in excess of the central bank's reserve requirements. The deposit multiplier is, thus inextricably tied to the bank's reserve requirement. This measure tells us how much new money will be created by the banking system for a given increase in the high-powered money. It reflects a bank's ability to increase the money supply. The credit multiplier is the reciprocal of the required reserve ratio. If reserve ratio is 20%, then credit multiplier = 1/0.20 = 5. 1 Credit Multiplier= Required Reserve Ratio The existence of the credit multiplier is the outcome of fractional reserve banking. It explains how increase in money supply is caused by the commercial banks’ use of depositors’ funds to lend money. When a bank uses the deposited money for lending, the bank generates another claim on a given amount of deposited money. For example, if A deposits ` 1000/ in cash at a bank (Bank X), this constitutes the bank's current total cash deposits. If the required reserve is 10 percent, the bank would lend ` 900/ to B. By lending B ` 900/, the bank creates a deposit for ` 900/ that B can now use. It is as though B owns ` 900/. This in turn means that A will continue to have a claim against ` 1000/ while B will have a claim against ` 900/. The bank has ` 1000/ in cash against claims of ` 1900/. In short, the bank has created ` 900/ out of "thin air" since these ` 900/ are not supported by any genuine money. At any time, the fractional reserve commercial banks have more cash liabilities than cash in their vaults. Now suppose B buys goods worth ` 900/ from C and pays C by cheque. C places the cheque with his bank, Bank Y. After clearing the cheque, Bank Y will have an increase in cash of ` 900/, which it may take advantage of and use to lend out ` 810/ to D which may again be deposited in another bank, say Bank Z. Again 10 per cent of ` 810 (` 81) has to be kept as required reserves and the remaining ` 719/ can be lent out, say to E. This sequence keeps on continuing until the initial deposit amount ` 1,000 grows exactly by the multiple of required reserves (in © The Institute of Chartered Accountants of India  1.35 MONEY MARKET 8.35 this case, 10%). Ultimately, the expanded credit availability would be 1000 + 900 (90% of 1000) + 810 (90% of 900) + 729 (90% of 810) + (90% of 719) +……. This summation would end with an amount which is equivalent to 1/10% of 1000, which is ` 10,000. Thus, in our example, the initial deposit is capable of multiplying itself out 10 times. In short, we find that the fact that banks make use of demand deposits for lending it sets in motion a series of activities leading to expansion of money that is not backed by money proper. It is interesting to know that there is no difference between the type of money created by commercial banks and that which are issued by the central bank. The deposit multiplier and the money multiplier though closely related are not identical because: a) generally banks do not lend out all of their available money but instead maintain reserves at a level above the minimum required reserve. b) all borrowers do not spend every Rupee they have borrowed. They are likely to convert some portion of it to cash. We need to keep in mind that creating money through credit by banks does not mean creating wealth. Money creation is not the same as wealth creation. * 1 NOTE While the Reserve Bank of India was pursuing all possible measures to encourage lending to combat the negative outcomes of COVID pandemic, the banks were risk averse to lending and were comfortable parking funds under reverse repo despite the very low reve rse repo rate of 3.35 per cent. The average deposit of funds in the overnight reverse repo window in India increased more than three times – from an average of Rs 2.4-lakh crore during the March quarter to Rs 7-lakh crores during the June quarter. In the month of May, banks parked nearly ` 8-lakh crores under reverse repo on a daily average basis.

SUMMARY  The measures of money supply vary from country to country, from time to time and from purpose to purpose.  The high-powered money and the credit money broadly constitute the most common measure of money supply, or the total money stock of a country.  High powered money is the source of all other forms of money. The second major source of money supply is the banking system of the country. Money created by the commercial banks is called 'credit money’.  Measurement of money supply is essential from a monetary policy perspective because it enables a framework to evaluate whether the stock of money in the economy is consistent with the standards for price stability, to understand the nature of deviations from this standard and to study the causes of money growth.  The stock of money always refers to the total amount of money at any particular point of time i.e. it is the stock of money available to the ‘public’ as a means of payments and store of value and does not include inter-bank deposits.  The monetary aggregates are: ▪ M1 = Currency and coins with the people + demand deposits of banks (Current and Saving accounts) + other deposits of the RBI; ▪ M2 = M1 + savings deposits with post office savings banks, ▪ M3 = M1 + net time deposits of banks and ▪ M4 = M3 + total deposits with the Post Office Savings Organization (excluding National Savings Certificates).  Following the recommendations of the Working Group on Money (1998), the RBI has started publishing a set of four new monetary aggregates as: Reserve Money = Currency in circulation + Bankers’ deposits with the RBI + Other deposits with the RBI, NM1 = Currency with the public + Demand deposits with the banking system + ‘Other’ deposits with the RBI, NM2 = NM1 +Short-term time deposits of residents (including and up to contractual maturity of one year),NM3 = NM2 + Long-term time deposits of residents + Call/Term funding from financial institutions © The Institute of Chartered Accountants of India  1.39 MONEY MARKET 8.39  The Liquidity aggregates are: ▪ L1 = NM3 + All deposits with the post office savings banks (excluding National Savings Certificates). ▪ L2 = L1 +Term deposits with term lending institutions and refinancing institutions (FIs) + Term borrowing by FIs + Certificates of deposit issued by FIs.  The Reserve money, also known as central bank money, base money or high powered money determines the level of liquidity and price level in the economy.  The money multiplier approach showing relation between the money stock and money supply in terms of the monetary base or high-powered money holds that total supply of nominal money in the economy is determined by the joint behaviour of the central bank, the commercial banks, and the public.  M= m X MB; Where M is the money supply, m is money multiplier and MB is the monetary base or high powered money. It shows the relationship between the reserve money and the total money stock.  The money multiplier is a function of the currency ratio which depends on the behaviour of the public, excess reserves ratio of the banks and the required reserve ratio set by the central bank.  The additional units of high-powered money that goes into ‘excess reserves’ of the commercial banks do not lead to any additional loans, and therefore, these excess reserves do not lead to the creation of deposits.  When the required reserve ratio falls, there will be greater multiple expansions for demand deposits.  Excess reserves ratio e is negatively related to the market interest rate i. If interest rate increases, the opportunity cost of holding excess reserves rises, and the desired ratio of excess reserves to deposits falls.  An increase in time deposit-demand deposit ratio (TD/DD) means that greater availability of free reserves for banks and consequent enlargement of volume of multiple deposit expansion and monetary expansion.  When the Reserve Bank lends to the governments under WMA /OD it results in the generation of excess reserves (i.e., excess balances of commercial banks with the Reserve Bank). © The Institute of Chartered Accountants of India.40 8.40 BUSINESS ECONOMICS TEST YOUR KNOWLEDGE Multiple Choice Type Questions 1.
