Description: Why do economies repeat the same boom-and-bust pattern roughly every 5–8 years? A short walkthrough of the short-term debt cycle — how expanding credit drives spending and confidence to a peak, why rising rates and tighter lending turn the tide, and how the contraction and trough finally clear the way for the next recovery.

1The short-term debt cycle is driven by fluctuations in credit; when credit expands, economic activity accelerates; when credit contracts, activity decelerates
2Expansion phase: Abundant credit drives spending, production increases, incomes rise, confidence builds, and borrowing accelerates further
3Peak phase: Spending reaches unsustainable levels, asset prices (stocks, real estate) soar, debt accumulates, and inflation may begin
4Contraction phase: Credit tightens (due to rising rates or lender caution), spending falls, production drops, incomes decline, unemployment rises
5Trough phase: Credit is most restricted, defaults are highest, confidence is lowest, and pessimism is pervasive
6Recovery phase: Credit slowly expands again, spending stabilizes, production recovers, confidence rebuilds, and the cycle repeats
7This cycle typically lasts 5–8 years, with expansion lasting 3–5 years and contraction lasting 1–3 years
