Samuel Benner’s cycle model & economic forecasting.

How an Ohio pig farmer turned a ruined farm into the most mathematically durable economic forecasting matrix in American history — mapping market tops, buying troughs, and financial panics from 1549 to 2269.

The Ohio farmer who decoded market cycles.

In the autumn of 1873, a severe financial panic swept across the United States. Railroad over-expansion failed, major banking houses collapsed, and the New York Stock Exchange halted trading for ten days. Millions of Americans lost their livelihoods, including an Ohio farmer named Samuel Benner.

Having lost his farm during the panic, Benner refused to view economic ruin as an act of random chance. He set out to answer a fundamental question: are market crashes, panics, and high-price booms governed by natural laws, or are they mere chaos?

Benner spent months analysing decades of historical price data for pig iron, corn, hogs, and financial panics. What he found was that price movements were not linear or random; they moved in repeating mathematical sequences. In 1875 he published his findings in a modest volume titled Benner’s Prophecies of Future Ups and Downs in Prices.

Benner’s core axiom — 1875

“There is a time in the affairs of men when taking the tide at the flood leads on to fortune… Steel, iron, corn, and stocks all obey cyclical periodicity. He who knows when to buy and when to sell will make fortunes.”

Published in Cincinnati, Ohio, 1875. The forecast table it contained has now run out of sample for 150 years.

The three interlinked master cycles.

Benner identified three distinct repeating series of years. Unlike naive fixed-year models, Benner recognised that market cycles compress and expand according to a rotating step:

Series A — 16 / 18 / 20 yrs

Financial panics

A 54-year macro cycle broken into repeating steps of 18, 20, and 16 years. Signals severe liquidity crises, crashes, and systemic resets.

Series B — 8 / 9 / 10 yrs

Good times & sell points

A 27-year cycle with repeating steps of 9, 10, and 8 years. Represents market peaks, economic euphoria, and optimum times to sell assets.

Series C — 11 / 9 / 7 yrs

Hard times & buy points

A 27-year cycle with repeating steps of 11, 9, and 7 years. Represents economic troughs, severe recessions, and generational buying opportunities.

Visualising Benner’s economic wave.

Benner did not publish a curve. He published a card — a ruled lattice of triangles headed Periods When to Make Money, with the three series stacked as rails and the interval counts printed on the diagonals. The plate below restages that card for the modern era, 1999 to 2053, so two full rotations of each rhythm are visible at once:

Series A panic years fall in 1999, 2019, 2035 and 2053, stepping 20, 16 and 18 years. Series B selling peaks form the upper rail at 1999, 2007, 2016, 2026, 2034, 2043 and 2053, stepping 8, 9 and 10 years twice over. Series C buying troughs form the lower rail at 2005, 2012, 2023, 2032, 2039 and 2050, stepping 7, 11 and 9 years. The next selling peak is 2026. 1999 2019 2035 2053 20 16 18 1999 2007 2016 2026 2034 2043 2053 8 9 10 8 9 10 7 11 9 7 11 2005 2012 2023 2032 2039 2050 A PANIC B SELL C BUY

Figure 1. Benner’s three series on one plate, 1999–2053, drawn to a true proportional scale. The upper rail is series B — good times, high prices, the time to sell — stepping 8, 9, 10 and round again. The lower rail is series C — hard times, low prices, the time to buy — stepping 7, 11, 9. Panic years head the plate, stepping 20, 16, 18. Because the spacing is proportional, the asymmetry is visible in the geometry itself: the 2005→2007 recovery is two years and nearly vertical, while the 2016→2023 decline runs seven and lies shallow. 2026 is ringed as the next selling peak.

The complete historical & projected master dataset.

The table below is the master dataset of Benner’s model, compiled by Jonathan Evans. It captures every recorded and calculated year for good times (B sell), hard times (C buy), and panic years (A), alongside the interval each year carries forward to the next turn in its own series. Series A is projected to 2269; series B and C to 2131.

Benner’s track record across 150 years.

When Benner published in 1875 he made out-of-sample predictions running decades into the future. The model called several of the most consequential turning points in modern financial history:

  • The 1927 panic year and the 1929 crash. Benner marked 1927 as a Series A panic (+16 from 1911), arriving just after the 1926 Series B high (+9 from 1918). The market peaked in late 1929 and fell into the Great Depression, bottoming at the 1931 Series C low (+7 from 1924).
  • The dot-com top, 1999. Benner mapped 1999 as both a Series A panic year (+18 from 1981) and a Series B high (+8 from 1991). The NASDAQ peaked in March 2000 and fell 78%.
  • The great financial crisis, 2007–2008. 2007 is a Series B high (+8 from 1999). The S&P 500 set its all-time high in October 2007, immediately before the global banking collapse.
  • The 2019 panic year and the 2023 trough. 2019 is a Series A panic year (+20 from 1999); 2023 is a Series C buying trough (+11 from 2012). Equities made a major low in late 2022 and early 2023 before a multi-year rally.
  • The 2026 high ahead. On the 8-9-10 rhythm, 2026 (+10 from the 2016 high) is the next Series B high-price peak.

Why does the Benner model work?

Forecasters reasonably ask how pig iron and corn data from the 1870s could bear on modern equity markets. The answer is that Benner’s intervals are not arbitrary — they are the same intervals independently identified elsewhere in economics:

  1. The 54-year Kondratieff wave. Benner’s panic cycle of 18 + 20 + 16 sums to 54 years — the length of the Kondratieff long wave, driven by infrastructure replacement and capital accumulation.
  2. The 18.6-year lunar node and real-estate cycle. The 16-18-20 panic rhythm averages 18 years, close to the 18.6-year movement of the Moon’s nodal axis that underlies the land-banking credit cycle. See The 18.6-year economic cycle.
  3. The 9-year Juglar business cycle. Both the 8-9-10 highs and the 11-9-7 lows average exactly 9 years (27 ÷ 3), matching the fixed-capital investment cycle described by Clement Juglar.

Conclusion.

Benner’s contribution was to demonstrate that markets are not chaotic. Individual news events supply the noise; the underlying intervals supply the trend. A forecaster who holds those intervals holds a map of time that runs for centuries.

Inside the curriculum we run Benner’s macro periodicity alongside W.D. Gann’s price angles and Louise McWhirter’s lunar degree triggers, so that a macro turn resolves into an actual execution date.

This essay presents Benner’s public framework. For the wider tradition his work sits inside, read The four researchers who built the forecasting tradition.
