Dalio's framework describing the recurring expansion and contraction of credit — operating on two scales: a short-term cycle of 5–8 years and a long-term cycle of 50–75 years.
Deeper Explanation
The short-term debt cycle is driven by central bank tightening and loosening: credit expands during easing, driving growth; then contracts during tightening, driving recession. The long-term debt cycle spans decades: as each short-term cycle ends, total debt as a share of income rises slightly — because each recovery requires more debt than the prior one. Over 50–75 years, debt reaches levels where it can no longer be serviced, triggering a long-term debt crisis (the Great Depression of 1929–1933, and the near-crisis of 2008). Recovery from a long-term debt crisis requires "beautiful deleveraging" — a balanced combination of austerity, debt restructuring, wealth redistribution, and central bank money creation — each applied in the right proportions to prevent either depression or hyperinflation.
