Cross-Case Statistics and Base Rates
Use this file when: You need quantitative calibration for scenario analysis. These are the statistical benchmarks from Dalio’s 48-case database.
Deflationary Deleveraging Base Rates (48 cases)
“Length of equity drawdown (months) Avg: 119, Range: 60 to 249 | Length of GDP drawdown (months) Avg: 72, Range: 25 to 106 | Change in debt-to-GDP post-stimulation: -54%, Range: -70% to -29%.” — a-00185
| Metric | Average | Range |
|---|---|---|
| Equity drawdown duration | 119 months (10 years) | 60–249 months |
| GDP drawdown duration | 72 months (6 years) | 25–106 months |
| Debt/GDP reduction | -54% | -29% to -70% |
| FX decline vs gold | -44% | -37% to -58% |
| Peak money creation | 4%/year of GDP | 1–9% |
| Peak fiscal deficit | -6% GDP | -1% to -14% |
Use these as scenario baselines: A US deflationary deleveraging scenario would involve ~10 years of equity underperformance and ~6 years of GDP contraction if a 1929-style response occurred. The 2008 response compressed these timelines significantly.
Depression Wealth Destruction
“The capitalists/investors class experiences a tremendous loss of ‘real’ wealth during depressions because the value of their investment portfolios collapses (declines in equity prices are typically around 50 percent), their earned incomes fall, and they typically face higher taxes.” — a-00172
Standard depression wealth impact profile:
- Equities: -50% typical (range -50% to -84%)
- Income: declines (earnings fall with the cycle)
- Taxes: rise (political redistribution under pressure)
- Net effect: significant real wealth reduction even for those who survive the crisis
Case Benchmarks
| Case | GDP Decline | Stock Decline | Duration |
|---|---|---|---|
| US 1929-33 | -26% | -84% | 4 years down, 8 years to recovery |
| US 2007-09 | -4% | -50% | 2 years down, 5 years to recovery |
| Japan 1989-2013 | 0% (flat) | -80% peak | 24 years stagnation |
| Greece 2008-17 | -25%+ | Large | 9 years |

US Civil War Debt Case
“The US Civil War was over the usual issues. As is typical of such conflicts, it was very costly and financed by debt that grew too great to be paid back. The US government’s debt went from 2% of GDP to 40% of GDP and interest payments alone ate up over half of the budget.” — a-00260
The Civil War is the US’s most severe domestic financing stress pre-WWI: debt/GDP from 2% to 40% in 4 years, debt service >50% of budget. The resolution was through a combination of inflation, debt restructuring, and eventual economic growth — typical beautiful deleveraging template.
Post-WWI/Post-WWII Base
“From 1918 until around 1930, in the West, there was another 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.” — a-00261
Post-war prosperity pattern: peace → innovation → debt-financed speculation → wealth inequality → bubble → bust. This 12-year cycle (1918-1930) is the shortest version of the full long-term cycle. The current parallel: post-Cold War peace (1991-2001) → tech innovation → debt-financed speculation → 2001 bust → reflation → 2008 bust → QE → tech bubble.
Key Inference from Cross-Case Analysis
Inference The most important cross-case lesson is that policy response speed and scale determines outcome severity. Same structural conditions (housing bubble, credit excess) produced -4% GDP in 2008 vs -26% in 1929 solely because of faster, more aggressive policy. For 2025+: the question is not whether a deleveraging will occur, but whether policy response will be 1929-style (delayed, wrong) or 2008-style (fast, comprehensive). Position size and hedging ratios should reflect this binary.
