Why Algorithmic Stablecoins Demand a New Risk Calculus

The core failure mode where price de-pegging triggers a positive feedback loop of collateral liquidations and mint/burn arbitrage. This is a non-linear, network-native risk.

• Collateral Multiplier: A 5% price drop can trigger a >50% TVL liquidation.
• Velocity Over Stability: Relies on perpetual growth; fails in sideways or bear markets.
• Arbitrage Inversion: 'Risk-free' arbitrage becomes the primary attack vector, as seen with Terra/LUNA.

Decentralized governance is often a facade. In a crisis, multi-sigs and admin keys are used to enact emergency measures that break the protocol's core promises.

• Admin Key Risk: Foundational parameters (e.g., collateral ratios, oracle feeds) are often mutable by a <10 person multi-sig.
• Social Consensus Failure: Governance attacks (e.g., Mango Markets) or voter apathy can hijack the treasury.
• The Upgrade Trap: A 'security upgrade' can be a bailout for insiders, redistributing value from holders.

All algorithmic systems are oracle systems. The reliance on external price feeds creates a single, fragile point of failure that is constantly under attack.

• Liquidity-Dependent Feeds: DEX oracles (e.g., Uniswap V2 TWAP) can be manipulated with flash loans and low liquidity.
• Censorship Vectors: Centralized oracle providers (Chainlink) can be pressured to censor data or go offline.
• Meta-Stability: The stablecoin's stability becomes dependent on the stability of another volatile asset's price feed.

To bootstrap demand, algo-stables create complex, layered yield farms that disguise intrinsic risk with unsustainable APY. This creates a systemic dependency on Ponzi-nomics.

• Yield Source Obfuscation: APY comes from minting new tokens, not real revenue.
• TVL ≠ Security: High TVL is a measure of embedded leverage, not durability. Abracadabra's MIM showed $10B+ TVL can evaporate.
• Contagion Channels: Failure cascades through integrated DeFi legos (Curve pools, lending markets).

The only viable model. Risk is shifted from algorithmic magic to verifiable, excess collateral. The innovation is in transparency and automation.

• Real-Time Attestations: Protocols like MakerDAO and Liquity provide continuous, on-chain proof of solvency.
• Non-Custodial Vaults: User-controlled collateral positions eliminate counterparty risk.
• Stability through Redundancy: >150% collateral ratios absorb volatility without death spirals.

Contain failure. Design protocols where a collapse in one asset or module does not nuke the entire system. This is DeFi's version of firewalls.

• Asset Caps & Debt Ceilings: Limit exposure to any single collateral type (e.g., Maker's Ilk system).
• Graceful Degradation: Implement pause mechanisms (Aave's Guardian) and emergency shutdowns that preserve value.
• Layer Separation: Keep algorithmic minting logic separate from core settlement and custody layers.

Algorithmic stablecoins like TerraUSD (UST) create a reflexive feedback loop between the stablecoin price and its collateral asset (e.g., LUNA). A price dip triggers mint/burn arbitrage, which increases sell pressure, accelerating the collapse. This is a non-linear, systemic risk that traditional stress tests miss.

• Key Insight: Risk is endogenous, not exogenous.
• Key Metric: >99% depeg in <72 hours for UST.

You need continuous, automated monitoring of liquidity depth, collateral velocity, and holder concentration. Tools like Chainlink Data Streams or custom oracles must track metrics like the health ratio of Frax Finance or the AMM pool dominance of a stablecoin.

• Key Benefit: Move from periodic audits to real-time risk signals.
• Key Metric: Monitor for >20% of supply in a single AMM pool.

Protocols like MakerDAO (DAI) and Liquity (LUSD) use excess collateral (e.g., 150%+ ratios) to ensure stability. This locks up massive capital, creating systemic fragility if that collateral (e.g., ETH) itself crashes. It's capital-inefficient and concentrates risk in a few asset classes.

• Key Insight: Safety ≠ Over-Collateralization.
• Key Metric: $10B+ in locked, unproductive capital.

Mitigate single-point failure by collateralizing with a basket of liquid staking tokens (stETH, rETH), real-world assets (RWAs), and other stablecoins. This reduces correlation risk and turns idle collateral into a yield-generating asset, as seen with MakerDAO's RWA vaults and Ethena's USDe synthetic dollar.

• Key Benefit: Improves capital efficiency and stability.
• Key Metric: Target <0.3 correlation between basket assets.

Many "decentralized" stablecoins rely on multisig governance for critical parameters (e.g., collateral types, fees). This creates a central point of failure and attack. The delay between identifying a threat and executing a governance vote (~1-2 weeks) is fatal in a crypto market crash.

• Key Insight: Slow governance cannot manage fast-moving risk.
• Key Metric: 7-14 day standard voting delay.

Embed risk responses directly into smart contract logic. Use keeper networks and circuit-breaker oracles to automatically adjust fees, mint/burn rates, or pause operations when pre-defined thresholds are breached. This moves critical defense from human committees to deterministic code.

• Key Benefit: Sub-second response to existential threats.
• Key Metric: <60 second automated response time.
