Is Bitcoin Really Correlated to the Stock Market?
You have probably seen it stated with great confidence: Bitcoin is heavily correlated to the stock market. The number gets thrown around online as if it is settled science. The actual data from the last decade paints a much messier picture, and the famous high figure you see cited is almost certainly being used wrong.
Where the high number comes from
The number people quote is real. It was measured during a specific 30-day window in early 2024, right after the spot Bitcoin ETF was approved in January. During that stretch, Bitcoin and the S&P 500 moved together almost in lockstep. That happened. But quoting that moment as the typical relationship is like measuring the hottest day of July and calling it the annual average temperature.
CME Group researchers looked at Bitcoin and major stock indexes from January 2014 through April 2025. The average “how linked are they” reading over the full decade was 0.20. Academic research found a similar number: 0.17. On a scale from 0 (completely unrelated) to 1 (moves in lockstep), Bitcoin has spent the last decade sitting far closer to “unrelated” than most people realize.
The years bitcoin went its own direction
Four separate times since 2019, Bitcoin moved in the opposite direction from the stock market for weeks at a stretch: October 2019, June 2021, December 2022, and again from October through November 2023.
The 2023 case makes the point clearly. Bitcoin finished that year up 160%. The S&P 500 finished up 24%. Both went up, so they must be moving together, right? Not according to the data. During the second half of 2023, the “how linked are they” 90-day reading dropped to 0.09. Near zero. Bitcoin was rallying because the four-year halving was approaching and a spot ETF looked likely. Stocks were rallying because inflation was easing. Two different stories, two different drivers, the same time period.
When does bitcoin actually move with stocks?
The pattern is consistent: they sync up during panic. When markets drop hard and fast, money rushes for the exits across everything at once. Bitcoin trades 24 hours a day and can be sold instantly, which means it gets hit fast when someone needs cash in a hurry.
March 2020 is the example most people remember. Stocks fell. Bitcoin fell. Both hit a low within days of each other. Then Bitcoin finished 2020 up over 300% while the S&P 500 gained about 16%. The panic pulled them together for a few weeks. The recovery went in completely different directions.
CME Group put it plainly. Higher readings appear during stressed market environments. The high numbers people cite are built on crash moments, then presented as if they describe the everyday relationship. They do not.
What this means if you own bitcoin
Bitcoin is not a stock. It has no quarterly earnings, no CEO, and no board meeting. Its total supply is capped at 21 million and the new-supply rate cuts in half roughly every four years on a schedule set in code. Those fundamentals run on a completely different clock than corporate profits or interest rate decisions.
That does not mean Bitcoin ignores the rest of the world entirely. A severe market crash that freezes liquidity everywhere will pull Bitcoin down along with everything else, at least for a while. But over any meaningful stretch of time, Bitcoin has spent far more of the last decade running its own cycle than tracking the S&P 500.
If you are making Bitcoin decisions based on “stocks are up today,” you are probably watching the wrong signal. The more useful question is where we are in the Bitcoin cycle. You can see exactly how Bitcoin and the S&P 500 have compared over time on the live S&P 500 vs Bitcoin chart. For the full set of on-chain tools worth watching for Bitcoin timing, the Bitcoin charts that actually matter is the right place to start. And if you want to understand how altcoins behave relative to Bitcoin itself rather than to stocks, why altcoins are just leveraged Bitcoin lays out that relationship.
Common questions
Is bitcoin correlated to the stock market?
Over the full decade from 2014 to 2025, the two moved together only about 20% as much as they would if they tracked each other perfectly. They sync most tightly during market panics, not during normal times.
Why does bitcoin drop when stocks drop?
During a fast market panic, traders sell whatever they can quickly to raise cash. Bitcoin trades 24 hours a day and is easy to sell, so it gets hit in the first wave. But the panic-driven drops often diverge within months as Bitcoin runs its own cycle.
Is bitcoin a good hedge against stocks?
Not a reliable one. Bitcoin does not consistently move opposite to stocks. It has during specific windows, but it also drops with stocks during crashes. It is better described as an uncorrelated asset over the long run than a true hedge.
Does bitcoin follow the S&P 500?
Not consistently. In 2023, Bitcoin rose 160% while the S&P 500 rose 24%, and the two were moving almost independently for months. The link spikes during crashes but drops back to near zero in calmer markets.
What drives bitcoin if not the stock market?
Bitcoin tends to run on its own internal cycle tied to the halving schedule, holder behavior, and market sentiment. These drivers are completely separate from corporate earnings or interest rate decisions.
