US 1929 Great Depression and Recovery (1929-1937)
Use this file when: Understanding the deflationary deleveraging template. The 1929-1937 case is Dalio’s primary reference for ugly → beautiful deleveraging transition.
Pre-Crisis: The Roaring 20s Bubble
“From 1918 until around 1930, in the West, there was a classic period of peace, great inventiveness, and productivity due to entrepreneurs coming up with great new products that were financed by debt and equity investments/speculations that produced big increases in wealth differences and bubbles.” — a-00261
The setup: technology (radio, automobiles, electrification) + debt-financed speculation + widening wealth inequality. The pattern is structurally identical to the current 2020s: technology (AI) + debt financing + wealth concentration.
The Bubble Top: 1928-1929
“In 1928, the Fed started to tighten monetary policy. From February to July, rates had risen by 1.5 percent to five percent. The Fed was hoping to slow the growth of speculative credit, without crippling the economy. As short-term interest rates rose, the yield curve flattened and inverted.” — a-00208
Top mechanism: Fed tightening → yield curve inversion → credit contraction → leveraged positions uneconomic → forced deleveraging → self-reinforcing collapse.
1929-1933 quantification: a-00220
- GDP: -26%
- Stocks: -84% (peak to trough)
- Homes: -24%
- Unemployment: 25%
The Ugly Deleveraging (1929-1933)
The “ugly” label: austerity without monetary offset produced pure deflationary depression.
- Smoot-Hawley tariffs (1930): raised import taxes → global trade collapse
- Hoover’s balanced-budget austerity: cut spending during depression → worse
- Fed tightened again (1931): defending gold standard → accelerated crisis
- Result: four years of compounding declines
“The capitalists/investors class experiences a tremendous loss of ‘real’ wealth during depressions because the value of their investment portfolios collapses, their earned incomes fall, and they typically face higher taxes.” — a-00172
The 1930 Bear Market Rally Trap
“After 50% decline, rebound on ‘it’s over’ sentiment + recency bias. Stocks then fell another 60%.” — a-00209
The 1930 bounce recruited investors who thought the bottom was in. They lost another 60% in the second leg. This pattern repeats in every deflationary depression — the bear market rally is the most dangerous point for new money.
The Beautiful Deleveraging: FDR’s First 100 Days (1933)
“On Sunday, March 5, the day after he took office, Roosevelt declared a national four-day bank holiday, suspended gold exports (effectively delinking the dollar from gold), and set a team to work on rescuing the banking system. It was a scramble to get as much done as possible in as short a time as possible.” — a-00212
FDR’s key moves:
- Bank holiday (stops bank runs immediately)
- Gold link suspended (enables monetary expansion)
- Banking rescue (recapitalization of solvent banks)
- Fiscal stimulus (New Deal spending programs)
The combination of deflationary debt restructuring + inflationary monetization is exactly the beautiful deleveraging formula. Recovery from 1933: stocks +97% in first year, GDP +8%/year through 1937.
Wealth Inequality and Political Risk
“Wealth gaps increase during bubbles and become particularly galling for the less privileged during hard times. If rich people share a budget with poor people and there is an economic downturn, there will be economic and political conflict. It is during such times that populism on both the left and the right tends to emerge.” — a-00177
The 1930s: FDR’s New Deal = populist left response. Top marginal rates rose to 94%. Labor unions expanded dramatically. Financial regulation increased sharply. The political economy of depression redistributes wealth in ways that affect all asset classes.
1929 vs 2008 Policy Response
“As is classic, periods of prosperity financed by debt growth lead to a debt bubble and a large wealth gap. The bubble burst in 2008 (like in 1929), interest rates were pushed down to 0% (like in 1931), which wasn’t enough easing.” — a-00157
The 2008 response avoided 1929’s mistakes: immediate ZLB acknowledgment + QE + fiscal stimulus + bank recapitalization. GDP fell only 4% vs 26%. The lesson: fast, massive, coordinated policy can transform ugly → beautiful deleveraging.
1931 International Contagion: Sterling Devaluation
“As other currencies devalued and the dollar rose, it created more deflationary/depressing pressures in the US. Sterling’s devaluation in September 1931 especially stunned global investors and sent shock waves through US markets.” — a-00211
The UK leaving gold in September 1931 triggered international contagion: dollar strengthened → US deflation worsened → investors questioned dollar credibility → gold/dollar selling began. When a major reserve currency devalues, it exports deflation to countries that remain pegged — the strong-currency country inherits deflationary pressure. This mechanism explains why competitive devaluations become self-reinforcing. — a-00211
The 1937 Policy Error: Premature Tightening
“The debate continued at the start of 1936. FDR wanted to signal a concern around inflation ahead of the election, so he urged that reserve requirements be tightened that spring.” — a-00213
The 1937-38 recession within the depression was caused by premature tightening: reserve requirements doubled in 1936-37, triggering a severe downturn while still in recovery. This is the canonical example of tightening too soon — a pattern repeated with European austerity in 2010-11. The lesson: don’t tighten until private sector debt/income ratios have fully normalized, not just until GDP growth turns positive. — a-00213
