Supply and Demand of Loanable Funds (With Explanations)!
To improve upon the classical macro theory by taking the influence of money into account, a school of thought developed which is popularly called the neoclassical school.
They built up the loanable-funds theory of interest. The principal contributors to the development of this theory are Knut Wicksell, Bertil Ohlin, Lindahl and Gunner Myrdal—all Swedish economists—D.H. Robertson and J. Viner, the English-speaking economists.
In the opinion of these writers, the classical theory was inadequate in as much as it completely ignored the influence of monetary factors on the rate of interest.
Their view was that in addition to such real factors as thriftiness, waiting, time preference and productivity of capital, monetary factors like hoarding and dishoarding of money, creation of credit by banks, loans for consumption must also be given their due in the determination of the rate of interest. They, therefore, incorporated these monetary influences into the ‘real’ framework of classical interest rate theory.
When savings are supplemented with hoardings and bank credit, the sum total is referred to as loanable funds. Similarly, loanable funds are demanded not for investment alone but for hoarding and consumption purposes.
The loanable funds theory uses the schedules of supply and demand for loanable funds while the classical theory used only the supply and demand schedules of savings for the determination of rate of interest. The loanable funds theory is also called neoclassical theory. We make a detailed study of the demand and supply sides of loanable funds.
Supply of Loanable Funds:
There are four important sources of the supply of loanable funds:
(3) Bank money, and
All of these sources are dependent upon the rate of interest, that is, they are interest-elastic.
Savings done by households and firms out of their incomes are the biggest source of loanable funds. The loanable fund theorists considered savings in two senses. The Swedish economists considered saving in the ex-ante sense which means savings planned out of the anticipated incomes. D.H. Robertson took savings as the difference between the income of the previous period and consumption of the current period (S = Yt-1– Ct).
In both these versions, savings were assumed to be interest-elastic; that is, the assumption was that the volume of saving increases with incomes and vice versa. It was conceded that savings by households depend on their income but the neoclassical contended that given the level of income, savings vary with the rate of interest.
It is not only individuals, business concerns also save. Business concerns always retain a part of their earning for ploughing back into their business whether they are individual enterprises, partnerships or joint stock companies. While other considerations may also work with them, their savings depend also upon the current rate of interest.
A high market rate of interest means a high cost of borrowing and this encourages business savings as a substitute for borrowing from the market. By saving thus the firms may not enter the loanable-funds market but this influences the rate of interest by reducing the demand for loanable funds. In Fig. 7.2, the curve S slopes from left upwards to the right showing that savings increase with rise in the rate of interest.
Dishoarding means bringing out hoarded money into use and thus constitutes a source of supply of loanable funds. Individuals are free to dishoard the idle cash balances from a previous period thereby making them active. People hoard money to satisfy their desire for liquidity. At a low rate of interest there is not much of an inducement to lends more at high rates of interest and less at lower rates. The supply curve of bank money (BM) is shown in the diagram to be sloping upward to the right, that is, it is interest-elastic.
Disinvestment means not providing sufficient funds for depreciation of equipment. It takes place when business concerns do not feel inclined to put part of their earnings into the depreciation fund which is used for replacement of existing capital equipment when it wears out. In effect this means a supply of active balances or loanable funds.
Disinvestment particularly characterizes declining industries or other industries in a period of high and booming rate of interest. As M.M. Bober has observed, “Disinvestment is encouraged somewhat by a high rate of interest on loanable funds. When the market rate is high some of the current capital may not produce a marginal revenue product to match this rate of interest. The firm may decide to let this capital run down and to put the depreciation funds in the loan market.” In other words, disinvestment is likely to be more at higher rates of interest and as such the disinvestment curve DI is shown in the diagram to be sloping upward to the right. We can obtain the total supply curve of loanable funds by a lateral summation of the curves of saving (S), dishoarding (DH), bank money (BM) and disinvestment (DI). The aggregate loanable fund supply curve SL also slopes upwards to the right showing the greater supply of loanable funds at higher rates of interest.
Demand for Loanable Funds:
The demand for loanable funds comes from many sides. The Classical theory emphasised only the investment demand but loanable fund theorists consider other sources as well, that is, dissaving and hoarding.
The most important factor responsible for the demand for loanable funds is the demand for investment. Investment is expenditure of funds on the building up of new capital goods and inventories. Rate of interest is obviously the cost of borrowing of funds for investment.
Entrepreneurs go on investing in a capital asset up to the point at which the cost of borrowing i.e. the rate of interest equals its expected marginal revenue productivity.
Since marginal revenue productivity of a capital asset falls as more units of it are produced, the businessmen are prepared to invest more only at lower rates of interest. In other words, the demand for loanable funds for investment purposes rises with a fall in the rate of interest, or is interest- elastic. The investment-demand curve is, therefore, shown to be sloping downward to the right. It is the curve L in the diagram.
Dissaving means consuming more than the income in the current period. It is the excess of expenditure of consumption over income and is thus negative saving. Some people are anxious to purchase such durable goods as houses, automobiles, refrigerators, television sets and air conditioners when they do not have the saving to pay for them.
They get it on installment basis and thus spend more than their current income. Dissaving is more at lower rates of interest and less at higher rates. Therefore, the dissaving curve DS is shown to be sloping from left downward to the right in the diagram.
Loanable funds are also demanded for hoarding purposes that is for the satisfaction of the desire of people to hold money. People like to hold money in idle cash balances when they feel that the current rate of interest on lending is not sufficiently high to induce them to part with their money and that in the near future they will be able to make better use of their hoarded balances.
Surely then inducement to hoard is greater at low rates of interest and less at high rates.
Hoarding is just the opposite of dishoarding. The curve of hoarding, II, is shown in the diagram to be sloping downward to the right. By a horizontal summation of the three curves of demand for loanable funds investment, dissaving and hoarding, we get the demand curve DL for loanable funds showing that the demand for loanable funds increases as the rate of interest falls.
Determination of the Rate of Interest:
The equilibrium rate of interest is determined by the interaction of the factors working on the demand and supply side of loanable funds. The rate of interest is determined where the demand curve DL intersects the supply curve SL. It is Oi. At any other rate, there would be disequilibrium in the loanable funds market and so it will have a tendency to come to the level Oi.
An important point about the rate of interest and loanable-fund theory must be noted here. It is about the stability of the equilibrium market rate of interest Oi. At the equilibrium rate of interest in the market, planned or ex-ante savings may not be equal to the planned or ex-ante investment in the market. This is the case shown in Fig. 7.2 also.
It can be easily seen here that at the equilibrium rate of interest Oi, investment is greater than saving. Since intended saving on the rate of interest Oi is greater than intended investment, it cannot be a stable rate of interest, for income will increase to shift the supply schedule of saving SL and hence of loanable funds to the right. This will change the rate of interest to curry it to the equilibrium level.
Knut Wicksell was the first to distinguish between ‘market rate’ and the ‘natural rate’ of interest. Market rate of interest is that which equates the supply of and demand for loanable funds. Natural rate of interest is that which not only brings the demand and supply of loanable funds into equality but equates saving and investment also.
In Fig. 7.2, Oi is the market rate of interest but it is not stable, for saving and investment arc equal at the rate ‘ON’ Since investment at the market rate is more than saving, income will rise and rate of interest will also do so till saving increases enough to be equal to investment.
The market rate of interest has, thus, a tendency to move to the natural rate through changes in income over a period of time. It is through this sort of period analysis that the loanable fund theorists brought changes in the level of income into their discussion of the rate of interest.
An Alternative Rendering of the Loanable Funds Theory:
The loanable fund theory discussed in the way given above is the simplest exposition. But slight concentration of attention shows us clearly that saving and dissaving, hoarding and dishoarding, investment and disinvestment are forces opposing each other. As these forces operate in the loanable funds market, it is their net effect which goes to determine the market rate of interest. A subtle rendering of the theory can, therefore, be presented in net magnitudes like net saving, hoarding and net investment.
The equilibrium rate of interest is that at which the demand for loanable funds is equal to their supply. Taking the individual components of the demand and supply side, we can write in symbols that the equilibrium prevails when
S+ DH + BM+ DI = I + DS+ H
In order to get net magnitudes, we transfer DS to left-hand side, DH and DI to right-hand side. The condition then reduces to
(S – DS) + BM = (I – DI) + (H – DH)
or Net Saving + Bank Money = Net investment + Net hoarding
or ∆S + BM = ∆I + ∆H
The essence of the equilibrium condition of the loanable-funds theory thus is:
net saving and the creation of hank money must equal net investment and the change in idle cash balances, in a period of time, for the equilibrium rate of interest to be determined
Criticism of Loanable Funds Theory:
The loanable-funds theory was the target of criticism of Lord J.M. Keynes and his followers. It was pointed out that the loanable-funds theory is just an extension or a variant of the classical theory: as such it was open to the same criticism as classical theory was. The difference between the loanable funds theory and the classical theory lay only in the meaning attached to savings.
In the classical theory they are savings out of the current income while in the loanable funds theory they are saving out of the previous income. The loanable funds theory includes, in addition to the real saving out of the previous period’s income, bank credit and activated idle balances.
But then the classical theory takes saving out of current income into account which may well exceed the savings of the loanable funds theory because current income is increased by bank credit or dishoarding.
This increases saving. There is, thus, for practical purposes, not much difference between the two theories except the fact that the term, ‘loanable funds’ has been substituted for ‘current saving.’ Really speaking the Pigovian supply schedule of savings amounts to the same thing as the Robertsonian or Swedish supply schedule of loanable funds.
Secondly, Keynes regarded the concept of hoarding in the loanable funds theory as dubious. He observed that as long as the amount of money remains the same, hoarding simply cannot increase or diminish, for money supply has to be in somebody’s cash balances at any time: the hoarding of money by one person must be offset by the dishoarding of another.
This criticism of the loanable funds theory however was misplaced in that Keynes would take the stock of money at a moment of time while the loanable fund theorists were thinking of the flow of loanable funds over a period of time.
In this context, G. N. Halm has rightly observed:
“The total quantity of money may well be the same in the beginning and at the end of the period, but the velocity of circulation of money may nevertheless have changed. And it is this change in the velocity of circulation of money which is partly caused by hoarding. An increase in idle balances at the expense of active balances is hoarding and results in a reduction in the velocity of circulation of money. The time duration of the idleness of money might change, changing at the same time the supply of loanable funds.”
Thirdly, it has been alleged that the loanable funds theory, like the classical theory, is indeterminate. Professor Alvin H Hansen argues that “the schedule of loanable funds is compounded of savings plus net additions to loanable funds from new money and dishoarding idle balances. But since the savings portion of the schedule varies with the level of disposable income, it follows that the total supply schedule of loanable funds also varies with income making the rate of interest indeterminate.”
It is however less than fair to say that loanable funds theory involves circular reasoning since it does not take the changes in income into consideration. The theory seeks to determine the rate of interest through period analysis.
In the theory, the supply of saving is taken to be determined by the income of the preceding period which, including other components of loanable funds, determines the rate of interest in the current period which, in turn, affects the determination of income of the succeeding period through investment.
Fourthly, the loanable funds theory is criticised for its attempt to combine the monetary factors and real factors influencing the rate of interest. The two sets of factors are entirely different in their origin and impact and. therefore, must be separately accounted for by taking the changes in income as the reconciling factor.
This has to be done to get a complete, determinate theory of interest and income determination. This is what has been done by Professor J. R. Hicks as a result of which we have now a determinate theory of the rate of interest meeting with the objections to the loanable funds theory.
J.R. Hicks told in that the rate of interest operates both as a monetary factor and a real factor in the asset market and the goods market respectively.
In economics, the loanable funds doctrine is a theory of the market interest rate. According to this approach, the interest rate is determined by the demand for and supply of loanable funds. The term loanable funds includes all forms of credit, such as loans, bonds, or savings deposits.What factors affect the supply and demand of loanable funds? ›
Several factors also affect the supply and demand of loanable funds more specifically, including monetary policy, private and public saving, and investment tax credits.

Definition of Loanable Funds
The supply of loanable funds comes from people and organizations, such as government and businesses, that have decided not to spend some of their money, but instead, save it for investment purposes. One way to make an investment is to lend money to borrowers at a rate of interest.
Interest rates can determine how much money lenders and investors are willing to save and invest. Increased demand for loanable funds pushes interest rates up, while an increased supply of loanable funds pushes rates lower.Which of the following factors determines the supply of loanable funds? ›
The supply of loanable funds is determined by household savings. What is a financial securities that represent promises to repay a fixed amount of funds? What is not a service that the financial system provides for savers and borrowers?Why does the supply of loanable funds slope upward? ›
The supply of loanable funds slopes upward because higher interest rates make it more costly to borrow. savers will make more funds available at lower interest rates.What causes the supply of loanable funds to decrease? ›
The fall in Public Saving will cause National Saving to fall, the supply of loanable funds will decrease and interest rates will go up. The higher interest rates will discourage private borrowing and tend to “crowd out” some private capital investment.Which of the following will increase the supply of loanable funds an increase in the? ›

Interest rate levels are a factor of the supply and demand of credit: an increase in the demand for money or credit will raise interest rates, while a decrease in the demand for credit will decrease them.Which of the following affects demand for loanable funds? ›
What factors shift the demand for loanable funds? Capital productivity is the main determinant of the demand for loanable funds. Investor confidence also affects the demand for loanable funds.Why the demand for loanable funds is downward sloping? ›
The demand curve for loanable funds is downward sloping, indicating that at lower interest rates borrowers will demand more funds for investment. The supply curve for loanable funds is upward sloping, indicating that at higher interest rates lenders are willing to lend more funds to investors.What is the source of the supply of loanable funds as the interest rate rises the quantity of loanable funds supplied? ›
The supply of loanable funds curve slopes upward. As the interest rate rises, the return on saving increases, and the quantity of loanable funds supplied increases. As the interest rate falls, saving becomes less attractive and consumption becomes more attractive, so the quantity of loanable funds supplied decreases.How does capital inflow affect supply of loanable funds? ›
These capital flows include direct investment, purchases of stocks and bonds and central bank purchases of assets. Capital inflows will increase the supply of loanable funds; capital outflows will decrease the supply of loanable funds.Which of the following will shift the supply curve for loanable funds to the right? ›
An increase in capital productivity will imply higher expected returns and thus an increase in the demand for loans. This will shift the demand curve of loanable funds to the right.How do you calculate quantity of loanable funds demanded? ›
Supply and Demand for Loanable Funds - YouTubeWhat is the source of the demand for loanable funds as the interest rate rises the quantity of loanable funds demanded? ›
Investment is the source of the demand for loanable funds. As the interest rate rises, the quantity of loanable funds demanded decreases.What changes supply of loanable funds? ›
Savings Rate: When consumers slow their consumption and start putting more of their income into savings, the demand deposits increase. This will increase the number of reserves that banks can loan out, which will increase the supply of loanable funds.
The elasticity of supply has a direct effect on the parameters mentioned above. If the supply is more elastic, the curve will be flatter. If the government borrowings increase, the interest rate will increase by less, and the fall in the national savings will be less.How do taxes affect supply of loanable funds? ›
An increase in the government tax reduces the disposable income of people. When the disposable income of people falls, savings fall too. This leads to a reduction in supply of loanable funds. So, when taxes are increased the real interest rate associated with the loanable funds increases.Which of the following would shift the supply of loanable funds to the left? ›
Negative KI inflows will cause the supply of loanable funds curve to shift to the left relative to its initial position. We can predict that the equilibrium interest rate will increase and that the equilibrium level of private investment will decrease when the country runs a trade surplus.What occurs in the loanable funds market? ›
The loanable funds market illustrates the interaction of borrowers and savers in the economy. It is a variation of a market model, but what is being “bought” and “sold” is money that has been saved. Borrowers demand loanable funds and savers supply loanable funds.What effect will an increase in interest rates have on the quantity of loanable funds supplied quizlet? ›

A change in supply leads to a shift in the supply curve, which causes an imbalance in the market that is corrected by changing prices and demand. An increase in the change in supply shifts the supply curve to the right, while a decrease in the change in supply shifts the supply curve left.
The rate of interest is determined at the point of intersection of the two curves—the supply of loanable funds curve (SL) and the demand for loanable funds curve, DL. Fig. 4 shows that the equilibrium rate of interest is EM; at this rate, the demand for loanable funds is equal to the supply of loanable funds i.e. OM.How does the supply and demand of LF influence the real interest rate? ›

Why Are the Money Supply and Short Term Interest Rates Inversely Related? When all else is equal, the inverse relationship between a country's money supply and short-term interest rates make it either more or less expensive for consumers to borrow. So when there is a greater supply of money, interest rates are lower.
