Great Contraction
The Great Contraction was the acute phase of monetary deflation in the United States spanning from late 1929 to early 1933, characterized by a roughly one-third collapse in the money supply (M2 measure), which transformed an initial stock market crash and recession into the depths of the Great Depression.[1][2] In their empirical analysis, economists Milton Friedman and Anna Jacobson Schwartz demonstrated through detailed historical data on deposits, currency holdings, and Federal Reserve actions that this contraction stemmed from systemic banking panics—triggered by the failure of over 9,000 banks—and the central bank's passive response, which allowed depositor withdrawals to erode the monetary base without offsetting open-market purchases or discount window lending.[3][4] This period saw industrial production plummet by nearly 50 percent, unemployment surge to 25 percent, and wholesale prices deflate by over 30 percent, effects Friedman and Schwartz causally linked to the liquidity shortfall rather than fiscal policy shortcomings or real shocks alone.[5] Their monetarist framework, grounded in quantity theory of money empirics, argued that the Federal Reserve's adherence to the real bills doctrine and gold standard constraints—rather than aggressive liquidity provision—amplified the downturn, a view later validated in consensus economic historiography despite initial Keynesian emphasis on demand deficiency.[6] The analysis highlighted preventable policy errors, including the Fed's reluctance to suspend gold convertibility or expand reserves amid panics in 1930–1931 and 1933, underscoring how institutional failures in monetary management prolonged deflationary spirals and credit contraction.[7]Overview and Definition
Definition and Scope
The Great Contraction denotes the acute phase of economic decline in the United States spanning from the business cycle peak in August 1929 to the trough in March 1933, as determined by the National Bureau of Economic Research (NBER) chronology of expansions and contractions.[8] This interval marked the most severe downturn in U.S. economic history up to that point, with real gross national product (GNP) plummeting by approximately 30 percent and industrial production falling by over 45 percent.[9] Economists Milton Friedman and Anna J. Schwartz coined the term in their seminal analysis, emphasizing the contraction's distinct monetary dimensions, including a roughly one-third collapse in the national money stock—from $26.6 billion in August 1929 to $17.3 billion by March 1933—driven by banking failures and Federal Reserve inaction.[1][10] The scope of the Great Contraction encompasses not only aggregate output and monetary aggregates but also systemic banking disruptions, with over 9,000 banks failing between 1930 and 1933, eroding public confidence and accelerating deposit withdrawals.[7] Friedman and Schwartz's framework delimits it as a monetary phenomenon distinguishable from broader Great Depression dynamics, attributing the depth of the decline to policy errors rather than exogenous shocks alone, such as the initial stock market crash.[11] While centered on the U.S. economy, its effects rippled internationally through trade and gold standard linkages, though the term's analytical focus remains on domestic institutional failures in money and credit provision.[12] This period's severity, exceeding prior contractions in duration and amplitude, underscores empirical regularities linking money supply reductions to output falls, with velocity adjustments amplifying the impact.[6]Key Characteristics and Metrics
The Great Contraction, from August 1929 to March 1933, was distinguished by a sharp monetary deflation, multiple waves of banking panics, and a cascading failure of financial institutions that amplified economic distress through reduced lending and liquidity. Unlike prior recessions, the episode involved systemic adherence to the real bills doctrine by the Federal Reserve, which prioritized short-term commercial paper over broader liquidity provision, exacerbating deposit outflows and currency hoarding. Deflation intensified debt burdens in real terms, while industrial output and investment collapsed amid falling demand and confidence, marking the period as the most severe peacetime contraction in U.S. history prior to modern metrics. Key metrics underscore the contraction's depth:| Metric | Change (1929–1933) | Source |
|---|---|---|
| Real GDP | -29% | [13] |
| Unemployment rate | Rose to 24.9% peak in 1933 | [14] |
| Money supply (broad measure) | -30% | [5] |
| M1 money stock | -27% | [15] |
| Industrial production index (Federal Reserve) | -51% (from 119 to 58) | [16] |
| Bank failures | Over 9,000 institutions (1930–1933) | [17] |
| Consumer prices (CPI) | -25% cumulative deflation | [18] |
