Mises on Credit Expansion

“But now the drop in interest rates falsifies the businessman’s calculation. Although the amount of capital goods available did not increase, the calculation employs figures which would be utilizable only if such an increase had taken place. The result of such calculations is therefore misleading. They make some projects appear profitable and realizable which a correct calculation, based on an interest rate not manipulated by credit expansion, would have shown as unrealizable.”

Mises’s mechanism is precise. Credit expansion is not a generic monetary stimulus; it is the issuance of additional fiduciary media offered on the loan market, which pushes the gross market rate of interest below the level at which voluntary saving and time preference would equilibrate it. “Credit expansion is present only if credit is granted by the issue of an additional amount of fiduciary media,” he writes in Human Action Ch. XVII §11 (Scholar’s Edition p. 431) — distinguishing it from the harmless reuse of repaid commodity-credit balances.

The damage is calculational, not monetary in the headline sense. Entrepreneurs read the suppressed rate as a signal that the public has saved more and is willing to wait longer for consumption. They lengthen the production structure — bidding for higher-order capital goods, longer-duration projects, interest-rate-sensitive sectors — on the false premise that the resources to complete those projects exist. They do not. The boom is the period in which this error is being committed; the bust is the period in which it is exposed and liquidated. The “gross market rate” framework is what makes Mises’s account a theory of malinvestment, not merely a theory of inflation. See Austrian Business Cycle Theory for the full structural account and Credit and Deferred Payment for the commodity-credit / circulation-credit distinction that the mechanism rests on.
