Bitcoin Correlation Calculator: BTC vs Stocks, Gold, Bonds

Bitcoin Correlation with Traditional Assets

Bitcoin's correlation with traditional asset classes determines whether adding BTC to a portfolio actually provides diversification or simply amplifies existing risk exposures. A cryptocurrency that moves in lockstep with the S&P 500 offers no diversification benefit, while one with consistently low or negative correlation reduces portfolio drawdowns during equity selloffs.

The reality is more complex than either narrative suggests. Bitcoin's correlation with equities, gold, and bonds shifts dramatically across market regimes. From 2011 to 2019, BTC exhibited near-zero correlation with virtually every traditional asset. Since 2020, the picture has changed: institutional adoption, ETF flows, and macro-driven risk sentiment have introduced periods of tight co-movement with stocks, followed by sharp decoupling episodes.

The following table summarizes Bitcoin's current and historical correlation with major asset classes across different rolling windows.

Data compiled from CoinMetrics, Bloomberg, CME Group, and ARK Invest research. Short-term correlations (30-day) fluctuate significantly: values shown reflect Q1-Q2 2026 readings. Longer windows smooth out regime-specific noise. For a direct performance comparison between Bitcoin and equities, see the Bitcoin vs S&P 500 returns tool.

How Rolling Correlation Works

Rolling correlation measures the Pearson correlation coefficient between two assets' daily returns over a sliding window. At each point in time t, the correlation is calculated using only the returns from the preceding n days. The window then advances by one day, producing a time series of correlation values.

The Pearson coefficient r equals the covariance of the two return series divided by the product of their standard deviations: r = Cov(X, Y) / (σ_X × σ_Y). Values range from -1.0 (perfect inverse movement) through 0 (no linear relationship) to +1.0 (perfect co-movement).

Window size matters. A 30-day window captures short-term regime shifts but produces noisy, sometimes misleading readings. A 90-day window is the institutional standard: it balances responsiveness with statistical reliability. A 1-year (252 trading day) window reveals structural trends but lags regime changes by months. The industry threshold for "meaningful" correlation is a sustained reading above +0.40 or below -0.40 (per Hashdex methodology).

Bitcoin-Equity Correlation Through Market Cycles

Bitcoin's relationship with US equities has gone through six distinct correlation regimes since 2017. Understanding these shifts is essential for anyone using BTC as a portfolio diversifier.

Pre-2020: The Uncorrelated Era

Before 2020, Bitcoin's correlation with the S&P 500 averaged approximately 0.01 over multi-year periods (NYDIG Research). BTC was predominantly held by retail crypto-native investors with minimal overlap with traditional equity portfolios. This near-zero correlation made Bitcoin an attractive portfolio diversifier in academic models.

The COVID Correlation Shock (March 2020)

Bitcoin's "uncorrelated asset" thesis faced its first major test when COVID-19 triggered a global liquidity crisis. Bitcoin dropped from roughly $9,000 to below $4,000 in days, a 55% crash that coincided with the S&P 500's fastest bear market in history. The 30-day BTC-SPX correlation spiked to 0.50-0.60. The driver was straightforward: margin calls and forced liquidations caused indiscriminate selling of all risk assets, regardless of fundamentals.

2020-2022: Persistent Macro Coupling

Post-COVID, Bitcoin remained correlated with equities far longer than most analysts expected. The median BTC-SPX correlation during this period settled around 0.40, with the BTC-NASDAQ correlation peaking at 0.894 in July 2022 (Bloomberg). Both asset classes responded to the same macro forces: Federal Reserve rate hikes, quantitative tightening, and shifting risk appetite. Retail platforms like Robinhood blurred the line further by letting the same investors trade stocks and crypto in a single app.

2023: Temporary Decoupling

In Q2 2023, BTC-SPX 90-day correlation dropped to just 0.09 (CoinMetrics State of the Network #214), its lowest reading since June 2021. The SEC's lawsuits against Binance and Coinbase drove crypto-specific narratives that separated Bitcoin from the AI-fueled equity rally. During the March 2023 banking crisis (Silicon Valley Bank collapse), Bitcoin briefly showed negative correlation with equities as traders rotated into crypto as a hedge against banking system risk.

2024: The ETF Re-Correlation

The approval of spot Bitcoin ETFs on January 10, 2024, fundamentally changed the correlation landscape. BlackRock's IBIT and Fidelity's FBTC channeled billions in institutional flows, mechanically linking Bitcoin to the same capital pools that trade SPY and QQQ. The BTC-SPX correlation surged to 0.87. However, mid-2024 produced a dramatic reversal: the 30-day correlation crashed to -0.82 in July 2024 (The Block) as Bitcoin pulled back from $71,000 while equities continued rallying.

2025-2026: Complex Regime

The current environment defies simple categorization. Bitcoin peaked near $126,000 in October 2025 before declining, while equities showed mixed performance. The 30-day BTC-NASDAQ correlation whipsawed from -0.68 (February 2026) to +0.74 (March 2026) within weeks. Structural drivers including the GENIUS Act stablecoin legislation, sovereign reserve asset discussions, and growing corporate treasury adoption are gradually reframing Bitcoin from a tech stock proxy toward something more independent, though the transition is neither clean nor complete.

Bitcoin vs Gold Correlation

The "digital gold" narrative implies that Bitcoin and gold should be positively correlated. The data tells a different story. Over the January 2020 to January 2026 period, the weekly return correlation between Bitcoin and gold was just 0.14 (ARK Invest). More recently, the relationship has turned sharply negative.

In March 2026, the 30-day BTC-gold correlation hit -0.88, a four-year low (CryptoQuant). Gold rallied to record highs near $5,589 per ounce while Bitcoin declined roughly 20% from its October 2025 peak. This divergence reflects a fundamental difference in what each asset responds to: gold absorbs geopolitical fear and central bank demand, while Bitcoin tracks global risk liquidity and speculative appetite.

For portfolio construction, this means Bitcoin and gold serve complementary rather than substitutional roles. Holding both provides exposure to distinct macro regimes. For a deeper analysis, see the Bitcoin vs gold comparison tool.

Bitcoin vs Treasury Bonds

Bitcoin's correlation with US Treasury bonds has been the most consistently low of any major asset pairing. The 3-year correlation between Bitcoin and TLT (the iShares 20+ Year Treasury Bond ETF) stood at just 0.26 through March 2024 (Fidelity), while ARK Invest reported a weekly return correlation of only 0.06 over the January 2020 to January 2026 period.

This structural independence makes bonds a genuine diversifier against Bitcoin volatility. During risk-off episodes, Treasury demand spikes (pushing bond prices up and yields down) often coincide with crypto pullbacks, creating a natural portfolio offset. The Bitcoin vs Treasury bonds comparison explores this dynamic in detail.

Bitcoin and the US Dollar (DXY)

The most consistently inverse correlation in Bitcoin's history is with the US Dollar Index (DXY). Since 2014, BTC and DXY have typically maintained a rolling correlation between -0.40 and -0.80. In April 2026, the 30-day reading hit -0.90 (CoinDesk), near-perfect inverse movement.

The mechanism is intuitive: a weakening dollar increases demand for alternative stores of value, including Bitcoin. Global liquidity conditions that weaken the dollar (rate cuts, quantitative easing, expanding fiscal deficits) tend to provide tailwinds for risk assets. In March 2026, JPMorgan noted a brief positive BTC-DXY reading, the first since before 2014, though it quickly reverted to the historical inverse pattern.

Portfolio Diversification Implications

The correlation data reveals three practical insights for portfolio construction:

• Bitcoin provides genuine diversification against bonds and real estate across all market regimes, with long-term correlations near zero
• Bitcoin's diversification benefit against equities is regime-dependent: strong during crypto-specific narratives, weak during macro-driven selloffs when all risk assets correlate
• Bitcoin and gold together provide broader coverage than either alone, since their low-to-negative correlation means they respond to different macro catalysts

The key caveat: correlations spike toward 1.0 during liquidity crises. The March 2020 COVID crash demonstrated that Bitcoin does not function as a safe haven during panic-driven, cross-asset liquidation events. Any portfolio allocation framework that relies on Bitcoin's low correlation must account for this tail-risk behavior.

Note: The industry threshold for "meaningful" correlation is a sustained 90-day reading above +0.40 or below -0.40. Short-term (30-day) readings that breach these thresholds for only a few weeks rarely indicate a structural regime shift.

Why Correlations Change Over Time

Bitcoin's shifting correlations are not random. Five structural forces drive correlation regime changes:

• Liquidity crises: margin calls and forced liquidations push all asset correlations toward 1.0 regardless of fundamentals
• Monetary policy: rate hike cycles create persistent positive correlation between Bitcoin and equities, since both respond to the same discount-rate mechanism
• ETF institutionalization: spot Bitcoin ETFs channel equity-market capital into BTC, mechanically linking flows and creating index-like co-movement
• Regulatory shocks: crypto-specific events (SEC lawsuits, exchange failures) decouple Bitcoin from equity narratives
• Narrative evolution: as Bitcoin transitions from "speculative tech asset" toward "sovereign reserve asset," its correlation structure shifts from equity-like toward gold-like over multi-year timescales

For investors evaluating Bitcoin's dominance within crypto portfolios, understanding these regime drivers is more useful than extrapolating from any single correlation snapshot.

Frequently Asked Questions

What is Bitcoin's correlation with the S&P 500?

Bitcoin's correlation with the S&P 500 is regime-dependent. The 5-year average 90-day rolling correlation is approximately +0.30 (Phemex), but readings have ranged from -0.82 (July 2024) to +0.87 (post-ETF approval in 2024). Before 2020, the correlation hovered near zero. Since institutional adoption through spot ETFs, the relationship has become more dynamic, alternating between tight coupling during macro-driven selloffs and sharp decoupling during crypto-specific events.

Is Bitcoin correlated with gold?

Despite the "digital gold" label, Bitcoin and gold have a weak long-term correlation. ARK Invest measured a weekly return correlation of just 0.14 over the January 2020 to January 2026 period. In early 2026, the relationship turned sharply negative: the 30-day correlation hit -0.88 as gold rallied to record highs while Bitcoin declined. Gold absorbs geopolitical fear; Bitcoin tracks risk liquidity. They serve complementary portfolio roles rather than substitutional ones.

Does Bitcoin diversify a stock portfolio?

Bitcoin provides genuine long-term diversification, but with an important caveat. Over 5+ year periods, the average BTC-equity correlation remains moderate (+0.30), which does improve portfolio efficiency. However, during liquidity crises (like March 2020), correlations spike toward 1.0 as all risk assets sell off together. Bitcoin diversifies best during normal markets and crypto-specific rally periods, not during panic-driven crashes.

What window size should I use for rolling correlation?

A 90-day window is the institutional standard: it balances responsiveness with statistical reliability. Use 30-day windows to spot emerging regime shifts, but treat single readings with caution since small sample sizes produce noisy results. Use 1-year (252 trading day) windows to identify structural trends. For research purposes, always compare multiple windows to distinguish between noise and genuine regime change.

Why did Bitcoin become more correlated with stocks after 2020?

Three factors drove the shift. First, the Federal Reserve's rate hike cycle (2022-2023) pushed both equities and crypto lower through the same discount-rate mechanism. Second, retail trading platforms like Robinhood blurred the investor base, with the same traders buying both stocks and crypto. Third, spot Bitcoin ETFs (approved January 2024) channeled equity-market capital directly into Bitcoin, mechanically linking the two asset classes through shared portfolio rebalancing flows.

How does Bitcoin's correlation with the US dollar work?

Bitcoin and the US Dollar Index (DXY) maintain the most consistently inverse correlation of any major asset pairing, typically ranging from -0.40 to -0.80 over rolling 90-day windows. A weakening dollar signals looser financial conditions and increased global liquidity, both of which support Bitcoin demand. In April 2026, the 30-day BTC-DXY correlation hit -0.90, near-perfect inverse movement (CoinDesk). This relationship makes DXY one of the most reliable macro indicators for Bitcoin price direction.

Can correlation predict Bitcoin's price?

Correlation measures co-movement, not causation. A high BTC-SPX correlation tells you the two assets are moving together, not that one drives the other or that the pattern will persist. Correlation regimes shift unpredictably: the BTC-NASDAQ 30-day reading swung from -0.68 to +0.72 within weeks in early 2026. Correlation is useful for portfolio risk management and allocation strategy, not for directional price prediction.
