The Mechanics of Algorithmic Stablecoin Collapse
Algorithmic stablecoins that rely on an endogenous twin token to absorb volatility (such as the Terra/UST model) are vulnerable to reflexive bank runs. When selling pressure overwhelms arbitrage incentives, the mint/burn mechanism enters a hyperinflationary spiral that destroys market confidence.
Reflexivity Warning:
When peg defense requires minting an unbacked governance token whose market cap is smaller than the stablecoin’s circulating supply, a catastrophic depeg is inevitable during stress.
Early Warning Indicators of Peg Stress
Depegs rarely happen without advance warning. On-chain liquidity pools (like Curve and Uniswap) show imbalances first as smart money exits before retail traders on centralized exchanges notice. When a stablecoin pool ratio skews beyond 80/20, peg defense is under severe stress.
Risk Management Rules for Dollar Holdings
- Hold primary dry powder in fully backed, regulated stablecoins (USDC) with audited Treasury bill reserves.
- Set automated alerts for any stablecoin asset that deviates more than 0.75% from its $1.00 peg.
- Never chase double-digit APYs on synthetic stablecoins that lack verifiable, independent liquid collateral.
