A conceptual sequence. Real implementations can add steps, intermediaries, and conditions.
A broad label with different designs
All automated stablecoins use code, but “algorithmic” commonly describes designs relying heavily on supply adjustments and conversion incentives. Some are partly collateralized; others pair the stable unit with a volatile balancing token. A synthetic dollar using externally backed hedging positions is a different mechanism: code alone does not make it a Terra-style design. Ask what the holder receives when exiting, what independently supports that asset, and who must absorb it under stress.
The apparent arbitrage can be circular
In a stylized two-token design, a holder exchanges one stable token for a target value of newly issued balancing tokens. When the stable token trades below target, this looks like an arbitrage opportunity. But the balancing token’s market price can fall as more of it is issued and sold. Each subsequent redemption then requires more units, increasing dilution and selling pressure. The redemption formula depends on a market that the redemption itself affects.
A run can defeat the intended feedback
If holders expect backing or exit liquidity to weaken, they may try to leave before others. A mechanism intended to contract stablecoin supply can simultaneously flood the market with the balancing asset. TerraUSD’s 2022 collapse is a historical example discussed by central-bank researchers, not a claim that every possible automated design is identical. The general lesson is to examine stress behavior and the source of external demand.
Subsidized demand is another dependency
A treasury-funded reward can encourage people to hold the stable token while funding lasts. That reward does not necessarily arise from sustainable borrower demand or underlying asset income. If the subsidy falls, demand can fall with it. A stabilization explanation should therefore separate the peg mechanism from any yield program built around the token. Calling the combined system “stable savings” obscures two different promises and their funding sources.
MAKE IT CONCRETE
A shrinking balancing price
Illustrative target redemption is 1 currency unit. With the balancing token priced at 10, redemption requires 0.1 token. At a price of 0.10, it requires 10 tokens: one hundred times as many units. This arithmetic does not predict any real system, but it reveals why issuing more of a falling asset may amplify rather than solve an exit problem.
FAILURE PATHS & COMMON MISREADINGS
Where the model can break
- An algorithmic conversion quote is not a guaranteed cash redemption.
- A high holding incentive can conceal dependence on a finite subsidy.
