The market capitalisation of crypto-assets has surged recently, fuelled by positive and broadening investor interest, including from traditional finance. Several key financial stability risks associated with crypto-assets have been identified, such as interconnectedness with traditional finance, market volatility, lack of transparency, and leverage. This article explores these risks, focusing on wealth effects and interconnectedness, while highlighting data gaps that challenge robust financial stability assessments.
1. Introduction
Investor interest in crypto-assets has grown exponentially, driving significant valuation gains. Crypto-asset valuations hit an all-time high in 2024, with market capitalisation reaching USD 3.7 trillion. However, by Q1 2025, prices corrected sharply, dropping to USD 2.8 trillion. Key drivers include:
- Regulatory approvals (e.g., U.S. Bitcoin ETPs).
- Favorable policies under new U.S. administrations.
- EU’s MiCAR framework, enhancing investor confidence.
Crypto-assets pose financial stability risks through:
- Interconnectedness with traditional finance.
- Market volatility and opacity.
- Liquidity mismatches and leverage.
This analysis focuses on the first two channels.
2. Wealth Effects Amid Rising Valuations and Household Exposures
Rising crypto prices amplify risks of adverse wealth effects. High volatility—especially in Bitcoin—means crashes could disproportionately impact retail and institutional investors.
Key Trends:
- Bitcoin dominance: Its share of total crypto market cap rose from 40% (2022) to 60% (2025), fueled by spot ETPs and derivatives.
- Volatility: Bitcoin’s 2024 returns outpaced tech stocks but were 3× more volatile than the S&P 500 (Chart A.2).
- Limited diversification: Bitcoin correlates closely with risky assets (e.g., tech stocks), offering minimal portfolio benefits.
Euro area household exposures remain modest but growing:
- 9.7% of surveyed households own crypto-assets (ECB CES, 2024).
- 54% hold under €1,000; 91% under €20,000.
- Total estimate: €75 billion (0.23% of household financial assets).
Future risks:
- 10% of non-owners plan to buy crypto-assets (up to 17% in some countries).
- Data gaps obscure true exposure levels.
3. Interconnectedness with Traditional Finance
Risks escalate as crypto links with traditional finance deepen. Channels include:
- Bank services (custody, deposits).
- Investment products (ETPs, derivatives).
- Stablecoin reserves (e.g., USDT, USDC).
Euro Area Banking Sector:
- Direct exposures: Minimal (€1M in crypto holdings, €600M in derivatives, 2024).
Indirect exposures:
- €4.7B in crypto custody services (2024 vs. €400M in 2023).
- Limited deposits from crypto firms (€1.2B in Q4 2024).
Non-Bank Financial Intermediaries (NBFI):
- €3.4B in crypto-related products (20% of total euro area holdings).
- Households hold 59% (€10B); non-financial corps 21% (€3.5B).
Stablecoins: A Critical Bridge
- 80% of crypto trades involve stablecoins (Chart A.6).
- USDT/USDC reserves: Comparable to top money market funds (MMFs) (e.g., USD 231B in Treasuries).

4. Data Gaps Mask Systemic Risks
Incomplete data hinders risk assessment, especially for:
- NBFI sector exposures.
- Leverage usage.
- Crypto-fraud metrics.
Hidden vulnerabilities:
- Contagion risks to banks via NBFI are underestimated.
- Global regulatory fragmentation exacerbates arbitrage risks.
5. Conclusion
Current trends suggest growing financial stability risks, though euro area impacts remain contained. Key actions:
- Close data gaps (e.g., NBFI exposures).
- Enhance global regulatory coordination (e.g., FSB standards).
- Monitor stablecoins and bank interconnectedness.
Vigilance is critical as crypto-assets integrate deeper into traditional finance.
