Bitcoin The Evolution of Correlation with U.S. Stocks: From Independence to Convergence
Bitcoin As an emerging digital asset, the correlation between its price movements and traditional financial markets—particularly the U.S. stock market—has long been a focal point for investors and analysts.In the early days, prior to 2017, Bitcoin’s correlation with traditional stock indices, such as the S&P 500, was extremely low. At that time, Bitcoin was primarily driven by its own technological developments, community sentiment, and the behavior of early adopters.
However, since 2017, as institutional investors have gradually entered the cryptocurrency market, the correlation between Bitcoin and traditional financial markets has significantly strengthened. Between 2020 and 2023, the correlation between Bitcoin and the Nasdaq 100 Index at one point surged to 0.6 or even above 0.8, indicating a high degree of convergence in their price movements.This is primarily because, amid rising macroeconomic uncertainty, institutional investors often view Bitcoin as a high-risk asset and sell it off in tandem with the stock market when markets come under pressure, causing it to move in the same direction as the stock market.
Recent Changes in Correlation: Moving Toward Independence or Inverse Movement
It is worth noting that the correlation between Bitcoin and U.S. stocks is not static; recent data indicates that it is undergoing significant changes:
- November 2024: The 30-day correlation between Bitcoin and the Nasdaq index fell to 0.46, one of the lowest levels in the past five years at that time.
- December 2025: The 30-day correlation between the Bitcoin and the S&P 500 Index fell further to -0.299, indicating an initial inverse trend.
- Late February 2026:Despite the decline in correlation with the broader market index, the 30-day rolling correlation coefficient between Bitcoin and the ETF tracking software stocks (IGV) reached approximately 0.73, and this correlation above 0.5 has persisted for over 18 months, indicating that Bitcoin still exhibits characteristics of highly volatile software stocks in certain specific sectors.
- As of July 21, 2026: The 30-day correlation between Bitcoin and the S&P 500 Index has fallen to -0.17, the lowest level since 2021. This means that over the past 30 days, Bitcoin has more often moved in the opposite direction of the S&P 500 Index.
These data indicate that the short-term correlation between Bitcoin and the broader U.S. stock market is weakening and has even turned negative, which may suggest that Bitcoin will no longer fully track the U.S. stock market during a market crash.
Key Factors Affecting the Correlation Between Bitcoin and the U.S. Stock Market
Bitcoin Changes in the correlation with U.S. stocks are influenced by various macroeconomic and market structural factors:
- Macroeconomic Environment: Macroeconomic factors such as inflation, interest rates, geopolitical tensions, and economic growth are crucial to the price movements of Bitcoin. Federal Reserve policy and interest rate decisions are particularly critical; lower interest rates typically increase market liquidity and boost demand for Bitcoin, while higher interest rates tighten liquidity and exert downward pressure.
- Institutional Adoption: Large-scale institutional adoption—such as the successful launch of Bitcoin spot ETFs—is a major driver of Bitcoin’s growing integration into the global financial system.Institutional investors incorporate Bitcoin into their portfolios, creating a correlation with traditional assets in terms of risk management and asset allocation. When large hedge funds and asset management firms face liquidity pressures due to falling stock markets, they may sell liquid Bitcoin to cover losses, causing the two to move in tandem.
- Market Sentiment and Positioning: Bitcoin’s positioning in investors’ minds has consistently oscillated between “digital gold” and “high-risk tech stocks.” When risk aversion intensifies, some investors may view it as a safe-haven asset; conversely, when risk appetite is high, they may regard it as a high-growth, high-risk asset.
Bitcoin The “Digital Gold” Debate and Safe-Haven Attributes
There are differing views in the market regarding whether Bitcoin can serve as “digital gold” or a safe-haven asset:
- Supporters: For example, OSL points out that Bitcoin’s fixed supply contrasts with the inflation of fiat currencies, leading it to be frequently viewed as a tool to combat inflation during periods of rising inflation.BlackRock has also argued that Bitcoin is an “emerging global currency alternative” with characteristics such as scarcity, decentralization, and non-sovereign status, and should therefore be regarded as a safe-haven asset.
- Skeptics: Ray Dalio, founder of Bridgewater Associates, has warned that Bitcoin poses risks related to privacy, market size, and quantum threats, and should not be viewed as a long-term store of value.Sina News previously noted that following Bitcoin’s sharp decline in October 2025, its correlation with U.S. stocks rose, while gold repeatedly hit new highs during the same period. The divergence in their price movements cast doubt on Bitcoin’s safe-haven attributes.TradingKey believes that ’s high volatility makes it more likely to be viewed as a risk asset rather than a stable safe-haven tool during most periods of macroeconomic shocks. OKX analysis suggests that Bitcoin has evolved into a “macro asset” sensitive to Federal Reserve policy, interest rate decisions, and geopolitical tensions, and its role as a barometer of market sentiment is becoming increasingly solidified.
Conclusion
As of July 22, 2026, the correlation between Bitcoin and the U.S. stock market exhibits complex and dynamic characteristics. Although the two have historically shown a high degree of convergence, recent data indicates that the short-term correlation with the S&P 500 Index has declined significantly, even turning negative.This suggests that Bitcoin may be developing more independent market behavior, and its performance during future U.S. stock market crashes will depend more on the macroeconomic environment, institutional capital flows, and the strategic positioning of the stock as either a risk asset or a safe-haven asset. Investors should continue to monitor these dynamics to fully understand Bitcoin’s role in the market.
