A Monetary History of the United States, 1867–1960
Summary
Friedman and Anna Schwartz's empirical monetarist tour-de-force — a chapter-by-chapter monetary history of the United States from the post-Civil War greenback era through the 1960 recession. The book's most consequential argument occupies Chapter 7, “The Great Contraction, 1929–1933”: the claim that the Federal Reserve allowed the money supply to fall by roughly one-third during the Depression's worst years, and that this monetary contraction — not the 1929 crash itself — produced the depth and duration of the Depression. The book demolished the Keynesian consensus that monetary policy was “pushing on a string” in depression conditions and rebuilt monetary economics around the proposition that nominal money supply is a primary macroeconomic variable. Ben Bernanke famously told Friedman at his 90th birthday that the Fed had been guilty as charged and would never repeat the mistake — a commitment he then operationalized as Fed Chair during the 2008 crisis.
Why It Matters for Bitcoin
Friedman's monetarism doesn't lead to Bitcoin in the way Austrian theory does — Friedman explicitly defended fiat with a stable rule (his “k-percent” constant-growth rule). But the book matters for Bitcoin advocates in two ways. First, it establishes the empirical claim that central-bank discretion produces enormous welfare losses when wielded badly — and the correlated case that no discretionary committee should ever be trusted with that much power. Bitcoin's rule-based monetary policy is effectively Friedman's k-percent rule, but with the rule enforced by code rather than by institutional commitment. Second, the post-2008 era validated a Friedman-adjacent thesis at industrial scale — and the Bitcoin community watched. Bernanke's response (QE, ZIRP, the modern Fed balance sheet) is precisely what Friedman's framework prescribed but at a magnitude that produced the longest asset-price expansion in modern history. Bitcoin's entire early-cycle thesis was a reaction to that.
