The Four-Year Cycle Bitcoin Playbook May No Longer Apply

April 24, 2026

Author: Matt - Director of Research & Analytics


There's a version of Bitcoin analysis that's fairly simple: wait for the halving, expect a bull market for the following year or so, expect a bear market for roughly a year after that, repeat. It's a framework that made sense for most of Bitcoin's history. I'm not sure it does anymore, and this week I want to explain why, and what I think we should be looking at instead.

 

This week at a glance:

  • Over 95% of all bitcoin that will ever exist is already in circulation, significantly reducing the halving's influence on supply dynamics.
  • Bitcoin now has institutional passive flows from ETFs and treasury companies absorbing multiples of the daily new supply.
  • Global M2 liquidity has an 85% correlation with Bitcoin's price, and the macro backdrop is becoming more favorable.
  • The ISM Purchasing Managers Index, a leading indicator of economic confidence, is showing early signs of recovery and has a strong historical correlation with S&P 500 forward returns.
  • The Value Days Destroyed metric has just entered accumulation territory, regardless of where we sit on a calendar-based cycle timeline.

 

Less Relevant

The halving has historically been one of the most significant structural drivers of Bitcoin's four-year cycle. An immediate 50% reduction in the daily supply of new coins entering the market is a meaningful economic event, and for much of Bitcoin's history, when the asset was smaller, less liquid, and predominantly retail-driven, its price impact was substantial and relatively predictable.

Over 95% of all bitcoin that will ever exist is already in circulation. The inflationary rate is already so low that halving it again moves the needle considerably less than it once did. Meanwhile, Strategy alone is currently absorbing more than twice the entire daily new supply of bitcoin through ongoing accumulation. ETFs bought close to $650 million of bitcoin in a single day recently. The structural demand now entering this market dwarfs the supply changes that the halving produces.

 

Liquidity

The S&P 500 has a 96% correlation with Global M2 liquidity over the past 15 years on the monthly chart. Bitcoin has an 85% correlation with Global M2 over the same period. Closer to home, Bitcoin's correlation with the S&P 500 itself sits at 93% over the same timeframe. These aren't loose relationships; they're some of the strongest cross-asset correlations in markets, and they tell you that what drives Bitcoin is predominantly the same macro force driving all risk assets: the availability of capital.

When you look at Global M2 on a year-on-year basis, measuring the rate of expansion and contraction rather than just the nominal level, Bitcoin's alignment with liquidity cycles becomes even clearer. After a period of deceleration, the year-on-year M2 trend is beginning to show early signs of turning, which historically has been a meaningful tailwind for both equities and Bitcoin. If the four-year cycle framework is becoming less reliable, the question is what to replace it with. The answer, supported by over a decade of data, is global liquidity.

Shifting Macro Signals

Beyond raw liquidity, the ISM Purchasing Managers Index, a measure of confidence and forward expectations in US manufacturing, has a historically strong correlation with Bitcoin price performance. When manufacturing sentiment improves, Bitcoin has tended to follow. We're currently seeing early signs of recovery in this indicator after a period of deterioration, which, combined with the liquidity picture, suggests the macro backdrop is becoming more supportive rather than less.

On-Chain Data

Separately from the macro picture, the on-chain data is pointing in the same direction. The Value Days Destroyed Multiple, which weights coin movement by both the USD value and the dormancy of the coins being moved, then compares a 30-day average to the prior year's average, has just entered its accumulation zone. This metric has a strong historical track record of identifying both overheated conditions at cycle peaks and undervalued conditions at cycle lows, and it's currently at some of its lowest readings in recent history.

Closing Thoughts

Liquidity is expanding. Manufacturing sentiment is recovering. Institutional demand is structurally absorbing multiples of the daily new supply. And the on-chain data is pointing toward accumulation territory independent of where we sit on a four-year cycle timeline. This doesn't mean cycles disappear. It means the halving is no longer the primary engine driving them, and waiting for a calendar date to dictate accumulation timing is increasingly difficult to justify with data.
