An algorithmic stablecoin uses programmed rules, market incentives, governance, or token-supply operations to pursue a price target. The label covers different designs: it does not by itself mean “unbacked,” guarantee a peg, or tell you whether holders have an enforceable right to redeem at par.
Mechanisms differ
Some designs use reserve assets or external collateral alongside automatic rules; others rely heavily on conversion between a stable-value token and a volatile “balance” token. Hybrid systems combine tools. The term is used inconsistently, so identify the actual collateral, who controls it, and the route available to a holder who wants to exit.
What TerraUSD illustrates
Before its May 2022 collapse, TerraUSD (UST) used an on-chain conversion mechanism that was intended to let a participant burn UST for a protocol-defined amount of LUNA and burn LUNA to create UST. This was not a promise that every holder could redeem UST for cash at a bank. When confidence and market liquidity weakened, issuing more LUNA to absorb UST redemptions diluted the balance token and added selling pressure; the mechanism could not force outside buyers to restore the target.
How to evaluate the design
Read the redemption terms and smart-contract rules, then ask what backs the target, whether reserves are independently reported, whether collateral can be liquidated under stress, how deep secondary-market liquidity is, and which administrators or governance actors can change the rules. Also examine oracle, custody, exchange, and concentration risks. A quoted yield or an advertised peg is not a guarantee.
Common misconceptions
“Algorithmic” is not a single technical category, and a token can have partial collateral or external reserves while also using automated supply rules. Conversely, a successful period near a target does not prove the design can meet redemptions during a run. A peg is an observed market price; the mechanism and legal redemption promise, if any, determine what holders can actually demand.
