# Algorithmic stablecoins: when the peg depends on incentives An algorithmic stablecoin relies heavily on programmed supply changes or exchange incentives to target a reference price. Designs vary, including partially collateralized hybrids. When support depends on demand for a related token, falling confidence can weaken both the stablecoin and the mechanism meant to stabilize it.

([SEC Division of Corporation Finance: Statement on Stablecoins](https://www.sec.gov/newsroom/speeches-statements/statement-stablecoins-040425)) - **Feedback:** A linked-token mechanism can depend on continued market demand. ([Tai Mo Shan settlement: UST stability claims](https://www.sec.gov/newsroom/press-releases/2024-212)) - **Evidence:** Observed recovery does not prove that autonomous code alone restored a peg. ([Tai Mo Shan settlement: UST stability claims](https://www.sec.gov/newsroom/press-releases/2024-212)) ## A rule still needs someone willing to transact A supply rule can create incentives to buy below a target or sell above it. It cannot force a market participant to value the output of that trade. This is the difference between defining an exchange rate in software and financing that exchange rate with assets someone else wants. Consider a hypothetical token redeemable for one dollar’s quoted value of a volatile partner token. If the partner token is worth $10, redemption creates 0.1 unit. At $1 it creates one unit. At ten cents it creates ten units. The rule still executes, while the quantity that must be sold rises dramatically. Evidence: [SEC Division of Corporation Finance: Statement on Stablecoins](https://www.sec.gov/newsroom/speeches-statements/statement-stablecoins-040425) ## Why falling demand can amplify itself In that simplified model, large redemptions increase partner-token supply just when people may be trying to exit. Selling pressure can lower its price, requiring more units for the next redemption. This is a mechanism example, not an assertion that every algorithmic design follows the same loop. Hybrids can include external collateral, limits or emergency interventions. Evaluate what is actually available after a price shock, who can change the rules and whether the claimed exit can absorb many simultaneous sellers. A nominal mint/burn ratio alone is incomplete evidence.

That record matters because a price returning toward a target does not prove the advertised automatic mechanism did all the work. Use dated incident findings rather than treating a short period of stable trading as a stress test. The useful questions are which mechanism operated, which outside resources intervened and whether those resources would still exist in a larger run. An encyclopedia should keep those observations separate from a protocol’s own claims.

All smart-contract tokens use software, but the usual category refers to how stability is financed and maintained. Collateralized debt systems are often distinguished from designs relying mainly on supply incentives.

No. A recovery can depend on outside purchases, available collateral and market confidence that may not recur.
