In 1974, commodity prices peaked after a 20-year bull run.

Oil had quadrupled. Copper was near record highs. Gold was surging. The economy felt strong. Inflation was high but growth was still positive.

Then the cycle turned.

Over the next 25 years, commodity prices fell. Not in a straight line — there were rallies, recoveries, false starts. But the general direction from 1974 to 2001 was down. Slowly. Persistently. Down.

That wasn’t bad luck. It wasn’t an oil shock. It wasn’t inflation policy getting out of control.

It was a 60-year cycle doing exactly what it always does.

A Russian economist named Nikolai Kondratiev spent years in the 1920s studying 140 years of commodity price data. He identified something that no one had noticed before.

Commodity prices — the prices of the raw materials that power industrial economies — didn’t just move randomly. They moved in long waves. Roughly 25 to 30 years of rising prices, then 25 to 30 years of falling prices. Then rising again. Then falling again. A full cycle of roughly 50 to 60 years.

He called these the Long Waves. Others named them after him — the Kondratieff Wave, or K-Wave for short.

But here’s what’s important to understand. The K-wave has an upswing and a downswing. Two phases. Each lasting roughly a generation.

Here are the five Long Waves since 1790:

We are approaching the crest of the Fifth Long Wave upswing. Commodity prices have broadly risen since 2001. Gold went from roughly $250 an ounce to over $4,000. Silver from $4 to over $70. Copper tripled. Oil, iron ore, agricultural prices — all ran hard over the past two decades.

And now, for the first time since 1974, the upswing is approaching its end.

Here’s the thing most people don’t understand about cycle transitions.

Nothing changes overnight. The shift from upswing to downswing doesn’t feel like a crash. It feels like the world is still mostly fine — but slowly, the things that worked stop working.

The 1815 transition: Britain had just won the Napoleonic Wars. The economy was strong. Then commodity prices began a slow, grinding 34-year decline. Farmers who had borrowed heavily found themselves squeezed between lower prices and fixed debt.

The 1873 transition (Long Depression): Commodity prices peaked after the railway boom and then fell for 23 years. What held value? Cash. Conservative businesses with no debt.

The 1920 transition: Commodity prices peaked in 1920, then began falling. By 1929, the land cycle peaked simultaneously, and the credit system collapsed. The Great Depression followed. The clearest historical example of K-Wave downswing and real estate cycle downturn arriving at the same time.

The 1974 transition: Oil peaked. Copper peaked. Then 27 years of commodity price decline. Growth stocks from the 1960s bull lost most of their value. What worked after 1974? Consumer staples. Short-duration bonds. Cash.

The pattern is consistent: when the K-Wave turns, what worked during the upswing gets punished. Commodity-linked assets, high-growth businesses, speculative credit. What survives is unglamorous: cash, defensives, businesses with real earnings and no debt.

Here’s where it gets interesting for 2026.

The research I follow states clearly: on the upswing of every past K-Wave, the 18.6-year real estate cycle downturns have NEVER been as severe as what happened during the downswing phases. The 2008 crash? That happened on the K-Wave upswing. Painful — but the system recovered in years, not decades.

What makes 2026 historically unusual is the convergence. The K-Wave crest is expected around 2026 — the same year the 18.6-year real estate cycle peaks. These two cycles are arriving at their turning point simultaneously for the first time in a generation.
