Executive Summary
The Bank of Italy’s research on Ethereum’s systemic risk highlights a critical vulnerability in blockchain-based financial infrastructure: the dependency on volatile native tokens for network security. This case study examines the implications for global finance and Singapore’s position as a digital asset hub.
Case Study: From Speculation to Systemic Infrastructure
The Transformation of Ethereum
2015-2020: Speculative Phase
- Ethereum launched primarily as a platform for decentralized applications and ICOs
- ETH valued mainly for speculative potential and gas fee payment
- Minimal integration with traditional finance
2021-2024: Financial Infrastructure Emergence
- Total value locked in DeFi protocols peaked at over $180 billion
- Major stablecoins (USDC, USDT, DAI) issued primarily on Ethereum
- Institutional adoption through tokenized assets and securities
- The Merge transition to proof-of-stake in September 2022
2025-Present: Systemic Importance Recognition
- Daily settlement volumes routinely exceed $10-20 billion
- Major financial institutions using Ethereum for tokenized bonds and funds
- Central bank digital currency experiments utilizing Ethereum-based infrastructure
- Regulatory bodies globally recognizing blockchain as financial market infrastructure
The Biancotti Risk Framework
Market Risk → Infrastructure Risk Transmission
The research identifies a dangerous mechanism:
- Initial Shock: ETH price drops 60-80% due to market panic, regulatory action, or technical failure
- Validator Economics Break: Running validators becomes unprofitable as rewards lose value
- Network Degradation: Validators exit, reducing staked ETH from ~30 million to critical levels
- Security Weakening: Lower stake makes the network vulnerable to attacks
- Transaction Delays: Block production slows, finality times increase
- User Exodus: Critical applications experience failures, triggering panic
- Feedback Loop: Network problems accelerate ETH price decline
Real-World Parallel: The Terra/LUNA Collapse (May 2022)
While different in mechanism, Terra’s death spiral demonstrated how token economics can destroy blockchain infrastructure:
- UST stablecoin depegged, triggering LUNA hyperinflation
- Network security collapsed as validators shut down
- $40+ billion in value evaporated within days
- Contagion spread to connected DeFi protocols and lending platforms
The key difference: Ethereum hosts vastly more systemically important applications.
Quantifying the Risk
Current Ethereum Financial Exposure (January 2026)
- Stablecoin market cap on Ethereum: ~$120-150 billion
- DeFi total value locked: ~$50-80 billion
- Daily transaction volume: $15-25 billion
- Number of validators: ~1 million
- Total staked ETH: ~30-33 million (~25-28% of supply)
- Major institutional projects: 50+ tokenized funds, bonds, and securities
Stress Scenario Modeling
Scenario 1: Moderate Shock (ETH -50%)
- Validator profitability reduced but sustainable for most operators
- Some smaller validators exit
- Network maintains functionality with minor degradation
- Risk level: Manageable
Scenario 2: Severe Shock (ETH -75%)
- Validator rewards drop below operational costs for 30-40% of operators
- Significant validator exits over 2-4 weeks
- Transaction finality delays from 15 minutes to 1-2 hours
- Stablecoin redemptions spike, creating liquidity stress
- Risk level: High systemic concern
Scenario 3: Catastrophic Shock (ETH -90%)
- Majority of validators become unprofitable
- Network security compromised, potential for attacks
- Applications experience failures and halts
- Mass exodus from Ethereum-based financial products
- Forced liquidations cascade through DeFi
- Risk level: Financial stability threat
Outlook: Regulatory and Technical Responses
Global Regulatory Trajectory
2026-2027: Assessment Phase
- Central banks and financial regulators conduct blockchain infrastructure reviews
- BIS, FSB, and IOSCO issue guidance on permissionless blockchain risks
- Jurisdictions begin classifying systemically important blockchain protocols
- First proposals for “critical crypto infrastructure” frameworks
2028-2030: Implementation Phase
Likely regulatory approaches:
Option A: Restrictive Framework
- Prohibit regulated financial institutions from using public blockchains for critical functions
- Require permissioned blockchain alternatives with known validators
- Mandate traditional backup settlement systems
- Limit stablecoin issuance on public chains
Option B: Conditional Authorization
- Permit public blockchain use with strict safeguards
- Require minimum economic security thresholds (e.g., $50B+ staked value)
- Mandate circuit breakers and emergency shutdown procedures
- Require dual settlement paths (blockchain + traditional rails)
- Implement real-time monitoring by financial authorities
Option C: Hybrid Approach (Most Likely)
- Tiered regulation based on systemic importance
- Larger stablecoins and tokenized securities face stricter requirements
- Smaller applications operate with lighter oversight
- Progressive compliance requirements as protocols grow
- International coordination through existing financial stability bodies
Technical Evolution

The Ethereum ecosystem is likely to pursue several mitigation strategies:
- Economic Security Enhancements
- Increase staking rewards during stress periods
- Implement dynamic validator incentives
- Develop insurance mechanisms for validator economics
- Finality Improvements

- Singapore has significant but manageable exposure, primarily through licensed entities and experimental programs rather than core financial infrastructure
- Proactive regulation offers strategic advantage, allowing Singapore to set global standards while managing risks
- Multi-chain resilience is essential, with backup systems and diversification requirements for any systemically important applications
- The window for action is 2-3 years before blockchain infrastructure becomes deeply embedded in critical financial systems
Recommendations for Singapore Policymakers
Immediate Actions (Next 6 Months)
- Establish MAS Blockchain Infrastructure Risk Taskforce
- Require stress testing and contingency plans from all licensed crypto entities
- Begin dialogue with international regulators on coordinated standards
- Commission comprehensive mapping of Singapore’s blockchain financial exposure
Strategic Initiatives (2026-2027)
- Develop tiered blockchain infrastructure classification framework
- Create real-time monitoring capabilities for systemically important blockchains
- Mandate diversification and backup systems for critical applications
- Launch research partnerships on blockchain resilience
Long-Term Positioning (2027-2030)

Final Assessment
The Ethereum infrastructure risk identified by the Bank of Italy represents both a challenge and an opportunity for Singapore. By moving proactively rather than reactively, Singapore can:
- Protect its financial system from emerging blockchain risks
- Establish global leadership in crypto regulation
- Attract quality blockchain projects seeking regulatory certainty
- Build resilient infrastructure that combines innovation with stability
The optimal path forward is neither blockchain skepticism nor uncritical adoption, but rather sophisticated risk management that allows controlled innovation. Singapore’s regulatory sophistication, financial infrastructure depth, and policy flexibility position it uniquely to pioneer this balanced approach.
The next 2-3 years will be critical in determining whether blockchain becomes a resilient part of financial infrastructure or a source of systemic instability. Singapore has the opportunity to help ensure the former while capturing significant economic and strategic benefits.
