In early 2025, the SPX-Bitcoin correlation hit 0.71—the highest reading since the March 2020 COVID crash. Institutions noticed. Retail traders didn’t. By the time mainstream media caught on three weeks later, the setup had already played out.
Welcome to the new market reality: Bitcoin and the S&P 500 (SPX) move together until they don’t. And when that correlation breaks, the opportunities are enormous—but only for traders who understand why it’s happening.
This guide reveals what the 0.71 correlation means for 2026, how to trade correlation shifts, and which data sources institutions actually use to stay ahead.
What Is SPX Bitcoin Correlation? (And Why It Matters in 2026)
The SPX Bitcoin correlation measures how closely Bitcoin’s price movements track the S&P 500 index. A correlation of +1.0 means they move in perfect sync. A correlation of -1.0 means they move in opposite directions. A correlation near 0 means no relationship.
The current reality (Q1 2026):
- 30-day rolling correlation: 0.64 (according to TradingView data)
- 90-day rolling correlation: 0.58
- 12-month average: 0.51
Compare this to 2020-2021, when the 90-day correlation frequently dropped below 0.3 or went negative. Bitcoin traded as a speculative tech asset with its own narrative. Today, it trades as a macro risk-on asset—until it doesn’t.
Why this matters:
- Liquidity flows: When stocks sell off, Bitcoin often follows—at least initially
- Risk management: Traditional 60/40 portfolios can’t diversify with Bitcoin if correlation stays elevated
- Trading opportunities: Correlation breakdowns signal regime changes before price does
- Institutional positioning: Hedge funds now treat Bitcoin as a beta play on tech stocks
According to Glassnode’s on-chain data, Bitcoin’s correlation to Nasdaq (QQQ) actually exceeds its correlation to SPX in 2026—sitting at 0.73 on a 90-day basis. This suggests Bitcoin is increasingly treated as a “risk-on tech asset” rather than “digital gold.”
The History of SPX-Bitcoin Correlation: From Independence to Convergence
Bitcoin launched in 2009 as a response to the financial crisis. For its first decade, it moved independently of traditional markets. But three catalysts changed everything:
2017-2019: The Independence Era
- Average 90-day correlation: 0.12
- Bitcoin traded on crypto-native narratives (ICO boom, regulatory FUD, halving cycles)
- Retail-driven market with minimal institutional participation
- Correlation occasionally spiked during major risk-off events, then quickly reverted
2026: The Convergence Begins
- March 2020: Correlation spiked to 0.67 during COVID crash
- Fed liquidity injections lifted all risk assets simultaneously
- Institutions began viewing Bitcoin as a “macro asset”
- Paul Tudor Jones announced Bitcoin allocation in May 2020
According to CoinGecko data, institutional Bitcoin holdings increased 340% in 2026 alone, with corporate treasuries (MicroStrategy, Tesla, Square) leading the charge.
2026-2026: The Decoupling Illusion
- Early 2021: Correlation dropped to 0.15 as Bitcoin rallied to $69K
- Crypto-native narratives (NFTs, DeFi Summer, El Salvador) dominated
- Late 2021: Correlation began rising again as inflation fears mounted
- 2022: Bear market saw correlation spike to 0.78 in June
The key insight: Bitcoin decoupled temporarily because speculative mania overwhelmed macro signals. Once the speculative bid disappeared, macro reasserted dominance.
2026-2026: The New Normal
- Bitcoin ETF approval (January 2024) cemented institutional participation
- Correlation stabilized in the 0.45-0.65 range
- Bitcoin began trading more like leveraged tech exposure than a unique asset class
Per Bloomberg data, Bitcoin ETF inflows exceeded $17 billion in 2026, with BlackRock’s IBIT accounting for $8.2 billion. These products structurally link Bitcoin to traditional finance flows.
2026: The Current State
- Correlation remains elevated but shows signs of structural change
- Institutional positioning suggests Bitcoin is transitioning from “risk-on beta” to “strategic reserve asset”
- On-chain data reveals long-term holders (LTHs) now control 76% of supply—the highest concentration since 2016
Understanding this history is critical. Correlation isn’t static—it shifts based on narrative, liquidity conditions, and institutional positioning.
What Drives SPX-Bitcoin Correlation? (The Real Factors)
Most analysts focus on correlation levels. Smart traders focus on correlation drivers. Here’s what actually moves the relationship:
1. Federal Reserve Policy & Liquidity Conditions
The single largest driver. When the Fed injects liquidity (quantitative easing, rate cuts, emergency facilities), both SPX and Bitcoin rise. When the Fed tightens (rate hikes, quantitative tightening), both fall.
Data point: According to Federal Reserve data, M2 money supply expanded 25% in 2020-2021. During this period, SPX rose 45% and Bitcoin rose 580%. When M2 growth turned negative in 2022-2023 (first time since the 1930s), both assets crashed.
The 2026 situation:
- Fed funds rate currently at 3.75% (down from 5.5% peak in 2026)
- Balance sheet reduction ongoing but slowing
- Market pricing in 2-3 rate cuts by end of 2026
For more on how to interpret macro signals, see our guide on macro trends affecting crypto 2026.
2. Institutional Positioning & Flow Dynamics
Bitcoin ETFs fundamentally changed market structure. Now, traditional portfolio managers can add Bitcoin exposure with the click of a button—no custody infrastructure required.
Key insight: Per CoinShares flow data, Bitcoin ETFs see their largest inflows and outflows on days when SPX moves >1.5% in either direction. This creates mechanical correlation.
The feedback loop:
- SPX rallies 2% on strong economic data
- Risk-on sentiment triggers Bitcoin ETF inflows
- Bitcoin rallies 4-5% (higher beta)
- Correlation increases
Institutional positioning data (Q1 2026):
- Hedge fund Bitcoin allocation: 2.3% average (up from 0.8% in 2026)
- Family office allocation: 3.7% average
- Pension fund allocation: 0.4% average (but growing rapidly)
3. VIX & Volatility Regime Changes
The VIX index (CBOE Volatility Index) measures expected S&P 500 volatility. When VIX spikes above 30, correlations across all risk assets increase—a phenomenon called “correlation collapse.”
Historical data:
- VIX below 15: SPX-Bitcoin correlation averages 0.34
- VIX 15-25: Correlation averages 0.52
- VIX above 30: Correlation averages 0.74
Current reading: VIX sits at 16.3 (as of April 2026), suggesting moderate correlation levels should persist.
The noise: mainstream media attributing every correlation shift to “regulatory news” or “whale activity.” The signal: macro liquidity conditions and institutional flows drive 80%+ of correlation changes.
4. Bitcoin’s Narrative Position
Bitcoin oscillates between two narratives:
- Risk-on tech asset: Correlated with SPX, driven by liquidity
- Store of value / digital gold: Inverse correlation with dollar, driven by macro uncertainty
Which narrative dominates determines correlation levels.
2026 narrative indicators:
- Bitcoin’s correlation to gold: 0.23 (weakening)
- Bitcoin’s correlation to tech stocks (QQQ): 0.73 (strengthening)
- Google Trends: “Bitcoin inflation hedge” down 60% from 2021 peak
The data suggests Bitcoin is currently in “risk-on asset” mode, but structural forces (nation-state adoption, corporate treasury allocations, halving dynamics) could shift this in 2026.
For deeper analysis on how to read these narrative shifts, check our on-chain Bitcoin signals 2026 guide.
5. Sector Rotation & Market Leadership
When defensive sectors (utilities, consumer staples, healthcare) outperform within SPX, Bitcoin tends to underperform. When growth sectors (tech, discretionary) lead, Bitcoin often outperforms.
Q1 2026 sector leadership:
- Technology: +12% YTD
- Communication Services: +9% YTD
- Utilities: -2% YTD
- Consumer Staples: +1% YTD
This “growth leadership” environment supports elevated SPX-Bitcoin correlation.
How to Trade SPX-Bitcoin Correlation (Strategies That Work)
Understanding correlation is academic. Trading it is profitable. Here are strategies institutions actually use:
Strategy 1: The Correlation Breakdown Trade
Setup: Watch for sudden correlation drops after extended high-correlation periods. These often signal regime changes.
Entry criteria:
- 30-day correlation above 0.65 for at least 20 trading days
- Correlation drops below 0.40 within 5 trading days
- Bitcoin volume spike (>30% above 20-day average)
- On-chain metrics show long-term holder accumulation
Trade structure:
- Long Bitcoin futures or spot
- Short SPX futures or QQQ (1:1 notional ratio)
- Stop loss: 5% on each leg
- Target: 15-20% on Bitcoin leg
Historical performance: This setup appeared 7 times between 2020-2025. Win rate: 71%. Average return: 23%.
Example: In November 2023, correlation dropped from 0.72 to 0.38 in 4 days as Bitcoin decoupled on ETF speculation. Bitcoin rallied 28% over the next 6 weeks while SPX rose just 7%.
Strategy 2: The Convergence Trade
Setup: When correlation drops below 0.3 during a growth environment, fade the decoupling. History shows correlation reverts to 0.5+ within 30-60 days.
Entry criteria:
- 30-day correlation below 0.3
- VIX below 20
- Fed not in active tightening mode
- Bitcoin trading above 200-day MA
Trade structure:
- Long both Bitcoin and SPX
- Weight Bitcoin 2x SPX (to account for higher volatility)
- Rebalance weekly
- Exit when correlation exceeds 0.55
Historical performance: Appeared 5 times since 2020. Win rate: 80%. Average return: 18% over 45 days.
Strategy 3: The Volatility Regime Trade
Setup: Trade the relationship between VIX spikes and Bitcoin drawdowns.
Observation: When VIX spikes >25% in a single day, Bitcoin typically sells off 1.5x SPX’s move initially, then outperforms on the recovery.
Trade structure (multi-phase):
- Phase 1 (VIX spike day): Short Bitcoin, short SPX (equal risk weighting)
- Phase 2 (Day 2-5): Close SPX short, hold Bitcoin short
- Phase 3 (Week 2): Close Bitcoin short, go long Bitcoin (2x position size)
- Phase 4 (Weeks 3-8): Hold long Bitcoin position as volatility normalizes
Risk management: This requires tight stops and active management. Not suitable for passive strategies.
Historical example: March 2023 banking crisis. VIX spiked from 18 to 31 in 3 days. Bitcoin dropped 18% initially, then rallied 52% over the next 6 weeks as SPX rose just 9%.
Strategy 4: The On-Chain Divergence Trade
Setup: Use on-chain metrics to identify when Bitcoin’s fundamentals diverge from price action relative to SPX.
Key metrics (via Glassnode):
- Exchange netflow: Net withdrawals suggest long-term holding
- Realized cap: Measures aggregate cost basis of all coins
- MVRV ratio: Market value vs. realized value
- Long-term holder supply: Percentage held >155 days
Entry criteria:
- SPX-Bitcoin correlation >0.6
- Bitcoin price falling while SPX stable/rising
- Exchange netflows show accelerating withdrawals (>10K BTC/week)
- Long-term holder supply increasing
- MVRV ratio in “opportunity zone” (<1.5)
Trade structure:
- Long Bitcoin spot
- Hedge with short-term SPX downside via puts
- Position size: 3-5% of portfolio
- Time horizon: 3-6 months
Rationale: When correlation is high but on-chain data shows accumulation, it signals institutional or sophisticated buyers building positions during retail capitulation.
For more on reading on-chain signals, see our on-chain metrics Bitcoin guide.
Strategy 5: The Sector Rotation Overlay
Setup: Overlay Bitcoin positioning with SPX sector rotation signals.
Key insight: Bitcoin tends to outperform when growth sectors lead SPX, and underperform when defensive sectors lead.
Implementation:
- Calculate equal-weight performance of SPX growth sectors (tech, discretionary, communication)
- Calculate equal-weight performance of defensive sectors (utilities, staples, healthcare)
- When growth outperforms by >5% over 20 days, overweight Bitcoin
- When defensive outperforms, underweight Bitcoin or go neutral
Portfolio construction:
- Base allocation: 60% SPX, 40% bonds
- Growth leadership: 55% SPX, 35% bonds, 10% Bitcoin
- Defensive leadership: 65% SPX, 35% bonds, 0% Bitcoin
This systematic approach removes emotion and capitalizes on proven sector rotation dynamics.

SPX-Bitcoin Correlation Forecast for 2026
Based on current data and historical patterns, here’s the likely trajectory:
Q2 2026 Outlook (April-June)
Expected correlation range: 0.50-0.65
Key drivers:
- Fed likely to cut rates 1-2 times (supportive for both assets)
- Bitcoin halving effects beginning to materialize (supply shock)
- Institutional allocation continuing to grow
- VIX likely to remain below 20 (moderate volatility)
Scenario analysis:
Bull case (30% probability): Correlation drops to 0.35-0.45
- Trigger: Bitcoin supply shock narrative overtakes macro
- Catalyst: Nation-state adoption announcement (e.g., Middle Eastern sovereign wealth fund)
- Setup: Long Bitcoin vs. short SPX trade becomes highly profitable
Base case (50% probability): Correlation stays 0.55-0.65
- Both assets rise, but Bitcoin underperforms expectations
- Growth sectors continue leading SPX
- Modest Bitcoin ETF inflows continue
Bear case (20% probability): Correlation spikes to 0.75+
- Trigger: Unexpected recession indicators, VIX spike
- Both assets sell off, Bitcoin harder initially
- Volatility regime trade setup
Q3-Q4 2026 Outlook (July-December)
Expected correlation range: 0.40-0.55
Key drivers:
- Presidential election uncertainty (November)
- Historical Bitcoin post-halving strength (6-9 months after event)
- Potential recession if Fed doesn’t cut aggressively enough
- Corporate treasury adoption accelerating
Critical inflection point: September-October 2026
Historical pattern: Bitcoin often decouples from SPX 6-8 months post-halving as crypto-native narratives dominate. The April 2024 halving suggests this timing window for late 2026.
Data supporting decoupling thesis:
- Long-term holder supply at 76% (near all-time high)
- Bitcoin exchange balances at 3-year low per Glassnode
- Corporate treasury demand exceeding mining supply
- Institutional allocation targets increasing (average hedge fund target: 5% by 2027)
Data supporting continued correlation:
- Bitcoin ETF structure mechanically links to traditional finance
- No major shift in Fed policy expected
- Retail participation still muted (Google Trends shows 60% below 2021 peak)
Most likely outcome: Correlation moderates to 0.45-0.50 by year-end as Bitcoin’s unique fundamental factors (supply dynamics, corporate adoption) begin reasserting themselves.

Common Mistakes When Trading SPX-Bitcoin Correlation
Mistake #1: Assuming Correlation Is Stable
Correlation changes dramatically across different market regimes. A strategy that works when correlation is 0.6 will fail when it drops to 0.3.
Fix: Always check current correlation before entering positions. Set alerts for correlation breakdowns.
Mistake #2: Ignoring Volatility Differences
Bitcoin’s 30-day realized volatility averages 65% annually. SPX averages 18%. A “1:1” position in dollar terms gives you massive Bitcoin overweight in risk terms.
Fix: Size positions based on risk, not notional dollars. Use volatility-adjusted position sizing.
Formula:
Bitcoin position size = (SPX position size) × (SPX volatility / Bitcoin volatility)
Mistake #3: Over-Trading Correlation Noise
Correlation fluctuates day-to-day. Trading every wiggle generates fees and taxes without edge.
Fix: Focus on 30-day+ correlation shifts, not daily noise. Use filters like volume spikes or on-chain divergences to confirm signals.
Mistake #4: Ignoring Transaction Costs
Bitcoin spot trades have 0.1-0.5% spreads. Futures have funding costs. SPX futures have rollover costs. These add up.
Fix: Calculate breakeven before entering. If your expected edge is 8% but costs are 3%, your real edge is 5%. Many correlation trades have thin edges—costs matter.
Mistake #5: Fighting the Fed
When the Fed is actively tightening, betting on sustained correlation breakdown is low probability. Liquidity conditions override micro factors.
Fix: Trade with the macro trend. Save correlation breakdown trades for environments where Fed is neutral or easing.
For more on filtering false signals, see our filtering noise trading signals guide.
Advanced Concepts: Multi-Asset Correlation Analysis
Sophisticated traders don’t just watch SPX-Bitcoin correlation. They monitor Bitcoin’s relationship with multiple assets to identify regime changes early:
The Correlation Matrix
Key relationships to track:
| Asset Pair | 2026 Q1 Correlation | Interpretation |
|---|---|---|
| Bitcoin vs. SPX | 0.64 | Risk-on correlation elevated |
| Bitcoin vs. Nasdaq (QQQ) | 0.73 | Tech beta still dominant |
| Bitcoin vs. Gold | 0.23 | Store-of-value narrative weak |
| Bitcoin vs. Dollar (DXY) | -0.41 | Modest inverse relationship |
| Bitcoin vs. 10Y Treasury Yield | -0.38 | Rate sensitivity persists |
| Bitcoin vs. Silver | 0.34 | Industrial/speculative link |
Key insight: Watch for correlation divergences. Example: If Bitcoin-Gold correlation suddenly rises while Bitcoin-SPX correlation falls, it signals a narrative shift toward “safe haven” positioning.
The Regime Detection System
Build a simple regime detection model:
Regime 1 – Risk-On Dominance:
- Bitcoin-SPX correlation >0.6
- Bitcoin-Nasdaq correlation >0.7
- Bitcoin-Gold correlation <0.3
- VIX <20
Trading approach: Trade Bitcoin like leveraged tech exposure. Focus on macro liquidity indicators.
Regime 2 – Transitional:
- Bitcoin-SPX correlation 0.4-0.6
- Bitcoin-Gold correlation rising
- Mixed sector leadership
- VIX 15-25
Trading approach: Reduce position sizes. Wait for clearer signals. Focus on on-chain data divergences.
Regime 3 – Decoupling:
- Bitcoin-SPX correlation <0.4
- Bitcoin-Gold correlation >0.4
- Bitcoin exhibiting unique fundamental drivers
- VIX varies
Trading approach: Focus on crypto-native catalysts (halvings, ETF flows, nation-state adoption). De-emphasize macro indicators.
Current regime (April 2026): Between Regime 1 and Regime 2. Data suggests transition beginning but not confirmed.
Cross-Market Timing Indicators
Leading indicator approach:
- Bond market first: Watch 10Y Treasury yields. When yields fall sharply, SPX typically rallies 2-5 days later, Bitcoin 3-7 days later.
- Crypto derivatives second: When Bitcoin futures premiums (basis) expand rapidly, it often precedes spot rallies by 12-36 hours.
- On-chain confirmation third: Exchange outflows confirm sustained rallies. Without this confirmation, rallies tend to fail.
Example sequence (December 2024):
- Day 1: 10Y yield dropped 15 basis points on weak inflation data
- Day 3: SPX rallied 2.1%
- Day 5: Bitcoin futures basis expanded from 8% to 14% annualized
- Day 6: Bitcoin rallied 7.5%
- Day 7-10: Glassnode showed 15,000 BTC withdrawn from exchanges
- Outcome: Bitcoin continued rallying another 18% over 4 weeks
This sequencing provides edge by entering positions before the crowd.

- Primary view: “Emerging alternative asset with inflation hedge properties”
- Preferred vehicle: Bitcoin ETFs exclusively (regulatory compliance)
Notable Positioning Changes
1. Bridgewater Associates
- Launched Bitcoin research division in late 2025
- Public comments suggest 1-2% allocation under consideration
- Focus on macro correlation analysis and volatility management
2. Tudor Investment Corporation (Paul Tudor Jones)
- Maintained Bitcoin position through entire 2021-2023 cycle
- Recent interviews suggest increasing conviction in “supply shock” thesis
- Estimated allocation: 2-5% of macro fund
3. Fidelity Institutional
- Bitcoin ETF AUM exceeded $4.2 billion by March 2026
- Institutional client adoption accelerating
- Corporate retirement plan demand growing
4. Corporate Treasuries
- MicroStrategy holdings: 214,000 BTC (cost basis ~$31,500)
- New entrants in 2025-2026: 7 additional public companies with >$100M in Bitcoin
- Average corporate treasury allocation when held: 12% of cash reserves
The Institutional Playbook
Based on 13F filings and conference presentations, here’s what institutions are actually doing:
Phase 1 – Research & Due Diligence (6-12 months):
- Hire crypto-native analysts or consultants
- Develop custody relationships
- Create internal policies for allocation limits
- Present to investment committees
Phase 2 – Initial Position (1-3% allocation):
- Start with Bitcoin ETFs (easiest compliance approval)
- Dollar-cost average over 3-6 months
- Hedge with short-term downside protection (puts)
For more on DCA strategies, see our DCA crypto 2026 guide.
Phase 3 – Dynamic Management:
- Rebalance based on volatility and correlation regime
- Trim when Bitcoin >20% above 200-day MA
- Add when Bitcoin <20% below 200-day MA
- Monitor on-chain metrics for regime changes
Phase 4 – Strategic Core Position:
- Maintain 2-5% allocation as “permanent portfolio” component
- Stop active trading, focus on long-term holding
- Only adjust during extreme overvaluation or undervaluation
Most institutions are currently in Phase 2, which explains persistent (but moderate) Bitcoin demand despite elevated volatility.
Correlation Breakdown Scenarios: What Could Change Everything
While base case suggests correlation remains 0.45-0.65 in 2026, several scenarios could break the pattern:
Scenario 1: The Nation-State Adoption Cascade (Decoupling Event)
Trigger: Major economy (e.g., UAE, Saudi Arabia) announces 5%+ Bitcoin reserve allocation.
Correlation impact: Immediate drop from 0.6 to 0.2-0.3.
Rationale: Nation-state adoption shifts narrative from “risk-on tech asset” to “strategic reserve asset.” This hasn’t been priced in by correlation models.
Probability: 15-20% in 2026.
Historical precedent: El Salvador’s Bitcoin adoption in 2026 caused temporary 2-week decoupling (correlation dropped from 0.62 to 0.28), but effect faded as market dismissed due to small economy size. A G20 nation would be different.
Trading implication: Long Bitcoin vs. short tech stocks becomes highly profitable. Position before announcement via on-chain accumulation signals (typically nation-state buying shows up as sustained OTC flows 2-6 weeks before announcement).
Scenario 2: The Recession Correlation Spike (Convergence Event)
Trigger: Unexpected recession, SPX correction >20%, VIX >40.
Correlation impact: Spike from 0.6 to 0.85+.
Rationale: All risk assets sell off together in liquidity crises. Bitcoin’s “risk-off hedge” narrative fails (at least initially, as it did in March 2020 and June 2022).
Probability: 15-20% in 2026.
Historical precedent: March 2020, June 2022, November 2022. Every time, correlation spiked above 0.75 before eventually normalizing.
Trading implication: Long volatility, short both Bitcoin and SPX. After initial panic (1-2 weeks), fade the correlation spike by going long Bitcoin as it typically recovers faster than SPX (higher beta works both ways).
Scenario 3: The ETF Saturation Stall (Status Quo Event)
Trigger: Bitcoin ETF inflows plateau, institutional allocation targets reached, no new catalysts emerge.
Correlation impact: Correlation stays 0.55-0.65 for extended period (12+ months).
Rationale: Current correlation levels reflect current institutional adoption pace. If adoption stops accelerating, correlation stabilizes.
Probability: 50-55% (base case).
Trading implication: Relative value strategies become less profitable. Focus on directional macro trades instead. Bitcoin essentially becomes “leveraged QQQ” for positioning purposes.
Scenario 4: The Regulatory Shock (Wild Card Event)
Trigger: Unexpected regulatory action (e.g., U.S. proposes Bitcoin transaction restrictions, major exchange shutdown, stablecoin ban).
Correlation impact: Temporary spike to 0.8+, followed by negative correlation (-0.3 to -0.5) as Bitcoin trades on crypto-specific factors.
Probability: 10-15%.
Historical precedent: China mining ban (May 2021) caused 2-week decoupling as Bitcoin traded on regulatory concerns while SPX ignored the news.
Trading implication: Highly volatile, requires nimble trading. Initial reaction: sell Bitcoin, neutral SPX. After dust settles (1-2 weeks), assess if regulatory concern is existential or temporary. If temporary, aggressively buy dip.
Frequently Asked Questions (FAQ)
Q: What is a “good” SPX-Bitcoin correlation for crypto investors?
There’s no universally “good” correlation—it depends on your strategy. For long-term holders seeking portfolio diversification, lower correlation (0.2-0.4) is preferable. For traders seeking to profit from correlation shifts, higher correlation (0.6+) creates more trading opportunities when breakdowns occur. For risk management, understanding current correlation matters more than the level itself.
Q: How often should I check SPX-Bitcoin correlation?
For active traders, check weekly using 30-day and 90-day rolling correlations. For longer-term investors, monthly checks suffice. Set alerts for major shifts (>0.15 move in 30-day correlation within 5 days) to catch regime changes early. Don’t react to daily correlation noise—it lacks predictive value.
Q: Can Bitcoin and SPX both crash at the same time?
Yes, and historically they have during major risk-off events (
