What Is Crypto Correlation?
Correlation measures how closely two assets move together. It's expressed as a number from -1 to +1. Understanding correlation is essential for portfolio management, pair trading, and anticipating market moves.
- +1.0 (Perfect positive): Assets move in lockstep. When one rises 5%, the other rises 5%.
- +0.7 to +0.9 (Strong positive): Assets usually move together but with some variation.
- +0.3 to +0.6 (Moderate): Some relationship but significant independent movement.
- 0 (No correlation): Assets move independently of each other.
- -1.0 (Perfect negative): Assets move opposite—rare in crypto outside of hedging instruments.
In crypto, most altcoins show 0.6-0.9 correlation with Bitcoin. This makes sense—BTC is the market leader, and when it moves, the entire market typically follows.
Why BTC Leads and Alts Follow
Bitcoin correlation dominates crypto for several reasons:
- Liquidity concentration: BTC has the deepest order books. Large trades start there.
- Institutional gateway: Most institutional money enters via BTC first, then rotates.
- Sentiment proxy: BTC price is the barometer for crypto risk appetite.
- Trading algorithms: Many bots use BTC as a reference signal for alt trades.
- Media/retail attention: BTC drives mainstream attention, which drives all flows.
When BTC drops sharply, liquidity leaves the market. Altcoins drop even harder because their thinner order books amplify moves. This "beta" relationship is why alts are often called "leveraged BTC bets."
Pair Trading: The Strategy
Pair trading profits from the relationship between two correlated assets, not their absolute direction. When the ratio between them deviates from normal, you bet on convergence.
How Pair Trading Works
- Identify correlated pair: ETH/BTC, SOL/ETH, or similar with 0.8+ correlation
- Calculate the ratio: Price A / Price B over time
- Define "normal" range: Mean ratio ± standard deviations
- Trade the deviation: When ratio hits +2σ, short A and long B. At -2σ, long A and short B.
- Close at convergence: Exit when ratio returns to mean
Example: ETH/BTC ratio normally trades 0.05-0.06. It drops to 0.045 (ETH underperforming). You long ETH and short BTC equally. When ratio returns to 0.055, you profit regardless of whether BTC went up or down.
| Pair Type | Example | Correlation | Best Use Case |
|---|---|---|---|
| Same sector | ETH/SOL | High (0.85+) | L1 rotation trades |
| BTC vs Alt | BTC/ETH | Very high (0.90+) | Altseason timing |
| Cross sector | DeFi/Gaming | Moderate (0.6-0.75) | Sector rotation |
| Staked variants | ETH/stETH | Near perfect (0.98+) | Arbitrage, low risk |
When Correlations Break Down
Correlation breakdowns create the best trading opportunities. When normally correlated assets diverge, it's either a temporary dislocation (trade convergence) or a structural change (trade the new trend).
Causes of Correlation Breakdown
- Asset-specific news: An ETH upgrade doesn't affect BTC. ETH rallies independently.
- Sector rotation: Money flows into AI coins while DeFi lags—sector correlations break.
- Liquidity crisis: In panic, correlations can spike to 1.0 as everything sells.
- Altseason: When BTC consolidates, alts can rally independently, breaking correlation.
- Specific catalysts: Airdrops, hacks, regulatory news create asset-specific moves.
The key question: Is this temporary or structural? A flash crash that breaks correlation for hours is temporary—trade mean reversion. A new narrative driving one sector is structural—trade the trend.
The ETH/BTC Ratio: The Most Important Pair
The ETH/BTC ratio is the most watched pair in crypto. It tells you which of the two largest assets is showing relative strength.
- Rising ETH/BTC: ETH outperforming. Often signals risk-on sentiment, potential altseason.
- Falling ETH/BTC: BTC outperforming. Flight to quality, risk-off, or early bull market.
- Flat ETH/BTC: Both moving together. No relative rotation happening.
Historical pattern: In early bull markets, BTC leads and ETH/BTC falls. Once BTC consolidates at new highs, money rotates to ETH and the ratio rises. This pattern then cascades to alts.

Correlation Trading Strategies
Strategy 1: Mean Reversion Pairs
When a pair deviates significantly from its mean ratio, trade convergence. Best for highly correlated pairs (0.85+) where divergences are temporary.
Strategy 2: Correlation Breakdown Trade
When correlation drops suddenly, one asset is moving independently. Identify why and trade the stronger asset's direction. Often happens with asset-specific catalysts.
Strategy 3: Beta Rotation
In bullish conditions, rotate to high-beta alts (higher correlation volatility). In bearish conditions, rotate to BTC or stables. Use correlation to gauge beta.
Strategy 4: Correlation Regime Change
Track rolling correlation over time. When 7-day correlation diverges significantly from 90-day, the relationship is changing. This often precedes major moves.
Using Correlation for Portfolio Management
Correlation is essential for real diversification. If all your holdings are 0.9 correlated with BTC, you're not diversified—you have leveraged BTC exposure.
- True diversification: Include assets with correlation below 0.5 to each other
- Stablecoin allocation: 0 correlation provides actual hedging
- Cross-market exposure: Consider assets less tied to BTC (newer narratives)
- Risk management: In high-correlation markets, reduce position sizes—everything moves together
Common Correlation Trading Mistakes
- Using price instead of returns: Calculate correlation on percentage changes, not raw prices
- Ignoring regime changes: Correlations shift over time. Use rolling windows, not static calculations.
- Over-fitting pairs: Past correlation doesn't guarantee future correlation. Use fundamentally related assets.
- Ignoring liquidity: Low-liquidity alts have unreliable correlations. Stick to liquid pairs.
- Fighting structural changes: If a narrative genuinely changes an asset's role, correlation may permanently shift.
Frequently Asked Questions
What is crypto correlation?
Crypto correlation measures how closely two assets move together. A correlation of 1.0 means perfect positive correlation (they move identically). 0 means no correlation. -1.0 means perfect negative correlation (they move opposite). Most altcoins have 0.6-0.9 correlation with BTC.
Why does BTC correlate with altcoins?
BTC leads the crypto market because it has the most liquidity and institutional interest. When BTC moves, it affects overall market sentiment and liquidity. Altcoins follow because traders rotate between BTC and alts based on risk appetite, and many trading bots use BTC as a reference.
What is pair trading in crypto?
Pair trading involves going long one asset and short another correlated asset when their price ratio diverges from the mean. When ETH/BTC ratio drops below average, you long ETH and short BTC, betting they'll converge. It's a market-neutral strategy.
When do crypto correlations break down?
Correlations break down during: (1) Asset-specific news (hack, partnership, upgrade), (2) Sector rotation (capital flowing to specific narratives), (3) Extreme market conditions (panic selling or euphoria), (4) Altseason (alts outperform BTC). These breakdowns create trading opportunities.
How do I calculate correlation?
Use Pearson correlation coefficient on returns (not prices). Compare percentage changes over your lookback period (7, 30, or 90 days). Most trading platforms and tools like Thrive calculate this automatically. Values above 0.7 indicate strong correlation.
What is the ETH/BTC ratio?
The ETH/BTC ratio shows how many BTC one ETH is worth. It's used to gauge ETH's relative strength vs BTC. Rising ratio = ETH outperforming. Falling ratio = BTC outperforming. Traders use this to time rotation between the two largest crypto assets.
How do I use correlation for portfolio diversification?
For diversification, choose assets with lower correlation to each other. If all your holdings are 0.9 correlated with BTC, you're not diversified—they'll all crash together. Add some lower-correlation assets or stablecoins to reduce portfolio volatility.
What timeframe should I use for correlation analysis?
30-day correlation is standard for most trading decisions. 7-day shows recent shifts but is noisy. 90-day shows stable long-term relationships. Compare multiple timeframes: if 7D correlation differs significantly from 90D, the relationship may be changing.
