Remember that old chart everyone in crypto has been sharing lately? Well, the Benner cycle is back in fashion and sparking quite a debate among retail investors. The thing is, this business is over 150 years old, and many swear it predicted major financial crises since the 1920s. But recent economic reality is putting all that confidence to the test.

The guy who created this, Samuel Benner, was a farmer who suffered heavily during the 1873 crisis. After that, he decided to study price patterns and in 1875 published a book with his findings. He believed that solar cycles influenced harvests, which in turn affected agricultural prices. That’s where the idea of the Benner cycle came from: lines marking years of panic (sell), boom (sell too), and recession (buy). Basically, it’s a very simple chart, nothing complex mathematical models.

What’s interesting is that the Benner cycle aligned with real events like the Great Depression, the dot-com bubble, and the 2008 crash. Some investors point out that it even predicted the COVID collapse. And then comes the part that affects everyone in crypto: the chart suggested 2023 as the best year to buy and 2026 to sell at the top. Many in the cryptocurrency market used this to justify optimism for 2025 and 2026.

But look what actually happened. In April 2025, Trump announced controversial tariffs, and markets took a heavy hit. The crypto market cap plummeted from $2.64 trillion to $2.32 trillion. JPMorgan increased the likelihood of a global recession to 60%, Goldman Sachs to 45%. That completely contradicts the optimistic scenario the Benner cycle promised. Veteran trader Peter Brandt was quite skeptical: he said he trusts his own trades more than 150-year-old charts. For him, it’s more distraction than useful analysis.

Still, some investors keep believing. They say the Benner cycle works not because it’s magical, but because many people believe it does. Markets are also about psychology, collective memory, momentum. And indeed, the interest in searching for the Benner cycle skyrocketed in recent months, showing that retail investors are looking for optimistic narratives amid uncertainty.

Now, in May 2026, we’re seeing in practice whether the Benner cycle got the peak prediction right or wrong. Some say the chart is crazy, others believe history repeats itself. The truth is, no one knows for sure, but the debate around the Benner cycle remains alive in the crypto community. It’s worth studying, but not putting your entire strategy on a century-old chart.
