Stablecoin Depegs: Collateral Risks, Algorithm Failures, and Contagion
Summary
The article explains how stablecoins seek to hold a reference value and distinguishes supply-adjusting algorithmic designs from coins backed by fiat, commodities, or crypto assets. It describes several routes to a depeg: insufficient or illiquid reserves, falling collateral values, a failed stabilization mechanism, smart-contract problems, hacks, or network congestion. Its central risk lesson is that confidence and redemption capacity matter alongside the stated peg mechanism.
Two episodes illustrate different transmission paths. TerraUSD’s collapse in 2022 is linked to pressure on its incentive design and a loss of confidence, while USDC’s 2023 decline followed exposure of some reserves to Silicon Valley Bank; the article also notes spillover to DAI through its USDC holdings. These cases show that crypto stablecoins can transmit stress within DeFi and remain connected to traditional finance. The examples are explanatory rather than a systematic study, and the article does not validate a trading strategy. It suggests monitoring price deviations and futures positioning as possible warning signals, but gives no tested thresholds or evidence of predictive performance.
Key ideas
- Algorithmic stablecoins manage supply to defend a peg, while asset-backed coins rely on collateral and redemption confidence.
- A depeg can result from weak reserves, illiquid collateral, a failed algorithm, or technical disruption.
- TerraUSD and USDC illustrate how distinct vulnerabilities can trigger sharp peg losses and broader spillovers.
- Stablecoin exposures can link DeFi protocols to traditional banks and markets.
- Price deviations and futures long-short ratios are suggested as monitoring signals, without validated predictive thresholds.
