A causa das crises: Mises sobre a expansão de crédito por criação monetária

Credit Expansion

It is a fundamental fact of human behavior that people value present goods higher than future goods. An apple available for immediate consumption is valued higher than an apple which will be available next year. And an apple which will be available in a year is in turn valued higher than an apple which will become available in five years. This difference in valuation appears in the market economy in the form of the discount, to which future goods are subject as compared to present goods. In money transactions this discount is called interest.

Interest therefore cannot be abolished. In order to do away with interest we would have to prevent people from valuing a house, which today is habitable, more highly than a house which will not be ready for use for ten years. Interest is not peculiar to the capitalistic system only. In a socialist community too the fact will have to be considered that a loaf of bread which will not be ready for consumption for another year does not satisfy present hunger.

Interest does not have its origin in the meeting of supply and demand of money loans in the capital market. It is rather the function of the loan market, which in business terms is called the money market (for short-term credit) and the capital market (for long-term credit), to adjust the interest rates for loans transacted in money to the difference in the valuation of present and future goods. This difference in valuation is the real source of interest. An increase in the quantity of money, no matter how large, cannot in the long run influence the rate of interest.

No other economic law is less popular than this, that interest rates are, in the long run, independent of the quantity of money. Public opinion is reluctant to recognize interest as a market phenomenon. Interest is thought to be an evil, an obstacle to human welfare, and, therefore, it is demanded that it be eliminated or at least considerably reduced. And credit expansion is considered the proper means to bring about “easy money.”

There is no doubt that credit expansion leads to a reduction of the interest rate in the short run. At the beginning, the additional supply of credit forces the interest rate for money loans below the point which it would have in an unmanipulated market. But it is equally clear that even the greatest expansion of credit cannot change the difference in the valuation of future and present goods. The interest rate must ultimately return to the point at which it corresponds to this difference in the valuation of goods. The description of this process of adjustment is the task of that part of economics which is called the theory of the business cycle.

At every constellation of prices, wages, and interest rates, there are projects which will not be carried out because a calculation of their profitability shows that there is no chance for the success of such undertakings. The businessman does not have the courage to start the enterprise because his calculations convince him that he will not gain, but will lose by it.

This unattractiveness of the project is not a consequence of money or credit conditions; it is due to the scarcity of economic goods and labor and to the fact that they have to be devoted to more urgent and therefore more attractive uses.

When the interest rate is artificially lowered by credit expansion the false impression is created that enterprises which previously had been regarded as unprofitable now become profitable. Easy money induces the entrepreneurs to embark upon businesses which they would not have undertaken at a higher interest rate. With the money borrowed from the banks they enter the market with additional demand and cause a rise in wages and in the prices of the means of production. This boom of course would have to collapse immediately in the absence of further credit expansion, because these price increases would make the new enterprises appear unprofitable again. But if the banks continue with the credit expansion this brake fails to work. The boom continues.

But the boom cannot continue indefinitely. There are two alternatives. Either the banks continue the credit expansion without restriction and thus cause constantly mounting price increases and an ever-growing orgy of speculation, which, as in all other cases of unlimited inflation, ends in a “crack-up boom” and in a collapse of the money and credit system.[1] Or the banks stop before this point is reached, voluntarily renounce further credit expansion and thus bring about the crisis. The depression follows in both instances.

It is obvious that a mere banking process like credit expansion cannot create more goods and wealth. What the credit expansion actually accomplishes is to introduce a source of error in the calculations of the entrepreneurs and thus causes them to misjudge business and investment projects. The entrepreneurs act as if more producers’ goods were available than are actually at hand. They plan expansion of production on a scale for which the available quantities of producers’ goods are not sufficient. These plans are bound to fail because of the deficiency in the available amount of producers’ goods. The result is that there are plants which cannot be used because the complementary facilities are lacking; there are plants which cannot be completed; there are other plants again whose products cannot be sold because consumers desire other products more urgently which cannot be produced in sufficient quantities because the necessary productive facilities are not ready. The boom is not over-investment, it is misdirected investment.


It is impossible to explain the cyclical changes of business on any basis other than the theory which commonly is referred to as the monetary theory of the business cycle. Even those economists who refuse to recognize in the monetary theory the proper explanation of the business cycle have never attempted to deny the validity of its conclusions about the effects of credit expansion. In order to defend their theories about the business cycle, which differ from the monetary theory, they still have to admit that the upswing cannot occur without simultaneous credit expansion, and that the end of the credit expansion also marks the turning point of the cycle. The opponents of the monetary theory actually confine themselves to the assertion that the upswing of the cycle is not caused by credit expansion, but by other factors, and that the credit expansion, without which the upswing would be impossible, is not the result of a policy intended to lower the interest rate and to invite the execution of additional business plans, but that it is released somehow by conditions leading to the upswing without intervention by the banks or by the authorities.

It has been asserted that the credit expansion is released by the rise in the rate of interest through the failure of the banks to raise their interest rates in accordance with the rise in the “natural” rate.[3] This argument too misses the main point of the monetary theory of the cycle. Whether the credit expansion gets under way because the banks ease credit terms, or because they fail to stiffen the terms in accordance with changed market conditions, is of minor importance. Decisive only is the fact that there is credit expansion because there exist institutions which consider it their task to influence interest rates by the granting of additional credit.[4] Whoever believes that credit expansion is a necessary factor in the movement which forces the economy into the upswing, which must be followed by a crisis and depression, would have to admit that the surest means to achieve a cycle-proof economic system lies in preventing credit expansion. But despite the general agreement that measures should be taken to smooth the wave-like movements of the cycle, measures to prevent credit expansion do not receive consideration. Business cycle policy is given the task to perpetuate the upswing created by the credit expansion and yet to prevent the breakdown. Proposals to prevent credit expansion are refuted because supposedly they would perpetuate the depression. Nothing could be a more convincing proof of the theory which explains the business cycle as originating from interventions in favor of easy money than the obstinate refusal to abandon credit expansion.

One would have to ignore all facts of recent economic history were one to deny that measures to lower rates are considered desirable and that credit expansion is regarded as the most reliable means to achieve this aim. The fact that the smooth functioning and the development and steady progress of the economy is over and over again disturbed by artificial booms and ensuing depressions is not a necessary characteristic of the market economy. It is rather the inevitable consequence of repeated interventions which intend to create easy money by credit expansion."
