Cryptocurrencies' Price Crash Risk and Crisis Sentiment

Abstract

We investigate the relationship between crisis sentiment and price crash risk in the cryptocurrency market. Our analysis reveals that cryptocurrencies' price crash risk is positively correlated with the FEARS index, suggesting heightened crisis sentiment among investors amplifies market instability. These findings enhance our understanding of how investor sentiment impacts cryptocurrency dynamics.

1. Introduction

Cryptocurrencies, led by Bitcoin, have emerged as a disruptive asset class characterized by extreme volatility and speculative trading. While prior research has explored returns, market efficiency, and hedging potential, few studies examine price crash risk—a critical concern for investors. This paper bridges that gap by analyzing how crisis sentiment (measured via the FEARS index) influences crash risk across 23 major cryptocurrencies (90%+ market capitalization).

Key Contributions:

1. Novel Explanation: First study linking crisis sentiment directly to cryptocurrency price crashes.
2. Behavioral Insights: Demonstrates how irrational investor behavior exacerbates market fragility.
3. Methodological Rigor: Combines high-frequency data with advanced econometric models.

2. Methodology

Data & Variables

• Sample: Daily data (2014–2020) for top 23 cryptocurrencies by market cap.

• Crash Risk Metrics:

  • NCSKEW: Negative skewness of weekly returns.
  • DUVOL: Down-to-up volatility ratio.
• FEARS Index: Tracks crisis-related Google search trends (Da et al., 2015).
• Control Variables: EPUI, VIX, and MSCI World Index.

Model Specifications

Fixed Effects regressions with clustered robust standard errors:

\text{NCSKEW}_t = \alpha + \beta \cdot \text{FEARS}_{t-1} + \gamma \cdot \text{Controls} + \epsilon_t  

3. Results

Key Findings

1. Positive Correlation: A 1-unit increase in the FEARS index raises crash risk by 0.23% (p < 0.01).
2. Robustness: Results hold across NCSKEW and DUVOL metrics (Tables 1–2).

Control Variable Insights

• VIX: Significant but weaker impact vs. FEARS.
• MSCI Index: Inverse relationship with crash risk.

4. Conclusion

Cryptocurrencies are highly susceptible to sentiment-driven crashes. Investors should monitor crisis sentiment indicators like the FEARS index to mitigate risks. Future research could explore sector-specific sentiment effects.

FAQs

Q1: How does the FEARS index measure crisis sentiment?

A: It aggregates Google search volumes for terms like "stock market crash" and "recession," reflecting real-time investor anxiety.

Q2: Why are cryptocurrencies more crash-prone than stocks?

A: Lack of fundamentals and high retail participation amplify sentiment-driven volatility.

Q3: Can cryptocurrencies act as a safe haven during crises?

A: Our data suggests no—cryptos often crash alongside traditional markets during high-FEARS periods.
