18.6-Year Real Estate Cycle

Compiled Truth

The 18.6-year real estate cycle is a recurring economic pattern where land prices rise for approximately 14 years, then fall for approximately 4 years. Each downswing is accompanied by a major stock market crash. The theory was developed and popularized by Fred Harrison and Phil Anderson, drawing on Henry George’s work on land speculation.

Cycle mechanics:

  • Land prices rise for ~14 years (land speculation phase)
  • Crash/contraction lasts ~4 years
  • Pattern repeats with rough 18.6-year periodicity
  • Mid-cycle correction (“winner’s curse”) occurs ~halfway through, often mistaken for end-of-cycle

End-of-cycle crashes (S&P 500 peak-to-trough):

  • 1929 → ~−86%
  • 1973–74 → ~−48% (~44 yrs later — two compressed cycles, WWII disrupted pattern)
  • 1989–90 → ~−20% (~16 yrs later)
  • 2007–09 → ~−57% (~18 yrs later — closest alignment to 18.6yr rhythm)

Mid-cycle correction:

  • 2000–02 dot-com crash = mid-cycle wobble within the 1990–2007 cycle (NOT end-of-cycle in Harrison/Anderson framework)
  • Occurs roughly halfway between cycle trough (1990) and land price peak (2006–07)
  • Phil Anderson explicitly identifies 2000–02 as “winner’s curse” correction

Next projected end-of-cycle: ~2025–26 (based on 18-year rhythm from 2007–09)

Key thinkers:

  • Fred Harrison — developed the 18.6-year cycle framework
  • Phil Anderson — popularized, authored “The Secret Life of Real Estate”
  • Henry George — intellectual foundation (land speculation and rent theory)
  • Steve Keen — heterodox economist, debt-cycle alignment

State

  • Active intellectual framework used by Floyd Marinescu for cycle analysis and investment decisions.
  • Floyd is a PSE (Phil Stock Exchange?) subscriber tracking this cycle.
  • Article published on progress.org: “The 18.6 Year Real Estate Cycle and Market Crash” — title updated 2026-05-17 via Webflow API.
  • Article correction made 2026-05-14: removed 2000–02 from end-of-cycle list, added 1989–90 (~−20%) as correct end-of-cycle figure; 2000–02 relabelled as midcycle correction.
