The State's Hidden Tax: Analyzing William Rees-Mogg's Case Against Fiat Currencies in The Crisis of World Inflation
Published in 1974, William Rees-Mogg’s The Crisis of World Inflation offers a stark and uncompromising critique of modern monetary systems. The book’s central argument revolves around the historical inevitability of failure for fiat currencies—money declared legal tender by a government but not backed by a physical commodity like gold.
The Inherent Flaw of Fiat Money
Rees-Mogg contends that history offers a clear lesson: all fiat currencies, regardless of the political system that issues them, eventually fail due to inflation. The root cause is the irresistible temptation for governments to print money as a short-term solution to fiscal problems. This process, evident in crises like the post-2008 financial bailout and the mass money creation during the COVID-19 pandemic, inevitably leads to the erosion of currency value.
Inflation as Hidden Taxation
The author defines inflation not merely as rising prices, but fundamentally as a form of hidden taxation—the state taking money from its citizens by stealth. Taxation is politically difficult, but printing money provides governments (whether democratic or autocratic) with an easier, less obvious mechanism to seize purchasing power.
The mechanism is explained using Irving Fisher’s Quantity Theory of Money, summarized by the equation MV = PT:
M (Money Supply): The amount of money in the economy.
V (Velocity): The rate at which money is spent.
P (Prices): The general price level.
T (Transactions): The number of transactions.
Rees-Mogg argues that when governments significantly increase the money supply (M), the easiest way for the equation to balance is for prices (P) to rise, absorbing the extra currency in the system. The book serves as a foundational warning against government debasement of the currency and implicitly encourages readers to consider real investments that hold value against monetary instability.
