Stablecoin Peg Mechanisms, Trading Uses, and Risks
Summary
The guide explains stablecoins as crypto assets designed to track a reference value, often a fiat currency or commodity, and outlines their use as a way to hold value between crypto trades or access decentralized finance. It distinguishes reserve-backed tokens, where a central issuer manages issuance and redemption and reserves may be audited, from crypto-collateralized and algorithmic designs. For algorithmic pegs, it describes how incentives to create or burn tokens can expand or contract supply when the market price moves away from the target.
The text emphasizes that these mechanisms do not guarantee a peg. It identifies issuer solvency, reserve transparency, redemption capacity, counterparty exposure, technical vulnerabilities, and manipulation as concerns. TerraUSD's 2022 collapse is presented as an example of a rapid loss of confidence and peg failure. The guide offers a general overview rather than a comparative assessment of specific tokens or evidence that any design reliably maintains its target under stress.
Key ideas
- Stablecoins aim to track a reference asset, but their market prices can deviate from it.
- Reserve-backed designs rely on issuer-managed issuance, redemption, and adequate reserves.
- Crypto-collateralized and algorithmic designs use different mechanisms to support their pegs.
- Algorithmic supply adjustments depend on incentives that can fail during sharp selling or attacks.
- The TerraUSD collapse illustrates the potential severity of a peg failure.
