In short
An algorithmic stablecoin holds no collateral and tries to defend its peg purely by expanding and contracting supply, usually by swapping against a second, absorbing token. Designs that rely on supply management alone, with nothing backing them, have collapsed rapidly once confidence broke. The category should be treated as experimental.
Key points
- No collateral: the peg is defended by changing supply alone
- A second, absorbing token usually carries the adjustment
- Designs of this type have collapsed rapidly once confidence broke
- With nothing backing it, redemption cannot put a floor under the price
Definition
A class of stablecoin design that holds no reserve assets and attempts to hold a target price by mechanically expanding or contracting its own supply in response to the market price.
The idea borrows from central bank open market operations: buy the token back when it trades below target, issue more when it trades above. Instead of holding reserves, most designs mint a second token that absorbs the adjustment and can be swapped for the stable one.
The design only works while buyers keep taking the absorbing token. In a break, both tokens are sold at once. The swap that was meant to shrink supply stops attracting demand, supply grows instead, and the price falls further — a reflexive spiral.
Designs that hold no collateral and rely on supply management alone have collapsed rapidly once confidence broke, with large losses spread across holders in a matter of days. Understanding the mechanism does not help much: such spirals rarely leave an individual holder time to exit.
Watch out for
- · Claims that the design 'returns to one dollar' assume buyers keep showing up
- · If demand is sustained by a high advertised return, ask where that return comes from
- · Once a break starts, liquidity disappears and exiting partway may be impossible
