Macroeconomic Analysis of Hyperinflation in the Weimar Republic

Abstract

This article argues that the hyperinflation in the Weimar Republic of Germany from 1921 to 1923 was not solely caused by "printing too much money", but rather the result of a systemic collapse of the three pillars of fiscal capacity, external balance, and public confidence. By examining the evolution of ideas from Fisher's quantity theory to the endogenous credit mechanism of Wicksell, and then to Lautenberg's institutional credit analysis, this article points out that the rapid expansion of the money supply is largely a passive response to deep-seated structural pressures. As fiscal deficits widen, compensation pressures intensify, and expectations continue to deteriorate, both the state and private sectors require increasingly large nominal currency balances solely to maintain basic transactions. The accelerated loss of public confidence has pushed up the velocity of currency circulation, making price increases a self reinforcing process that ultimately the Imperial Bank cannot control. Therefore, hyperinflation is not a mechanical result of monetary expansion, but the ultimate stage of systemic collapse of fiscal discipline, international solvency, and institutional credibility. This study suggests that sustained monetary stability relies less on limiting the quantity of currency and more on maintaining a credible fiscal foundation, controllable external obligations, and public trust in the currency and the country behind it.
