This phenomenon was, in the great European inflations of the ’20s, called flight into real goods (Flucht in die Sachwerte) or crack-up boom (Katastrophenhausse). The mathematical economists are at a loss to comprehend the causal relation between the increase in the quantity of money and what they call “velocity of circulation.”
The characteristic mark of the phenomenon is that the increase in the quantity of money causes a fall in the demand for money. The tendency toward a fall in purchasing power as generated by the increased supply of money is intensified by the general propensity to restrict cash holdings which it brings about. Eventually a point is reached where the prices at which people would be prepared to part with “real” goods discount to such an extent the expected progress in the fall of purchasing power that nobody has a sufficient amount of cash at hand to pay them.
The monetary system breaks down; all transactions in the money concerned cease; a panic makes its purchasing power vanish altogether. People return either to barter or to the use of another kind of money.
