Seigniorage
Profit from issuing stablecoins that cost less to create than their face value
Definition
In crypto, seigniorage refers to the profit a stablecoin protocol makes from issuing tokens that cost less to create than their face value. Algorithmic stablecoins use seigniorage mechanics: when demand increases, new tokens are minted (generating seigniorage profit), and when demand decreases, tokens are burned or bonds are issued to contract supply. This model has historically been fragile.
Example
Basis Cash and Empty Set Dollar used seigniorage models: when the stablecoin traded above $1, new tokens were minted and distributed to holders, but both ultimately failed to maintain their pegs.
What to check
Treat it as a token-design concept: inspect supply mechanics, holder incentives, redemption paths, and governance controls. The main checks are: Death spiral risk; Peg instability; Reflexivity / bank run dynamics.
Risks to Consider
- Death spiral risk
- Peg instability
- Reflexivity / bank run dynamics
Common Questions
Why have seigniorage stablecoins failed?
Most seigniorage stablecoins (ESD, Basis Cash, UST) failed because the mechanism to contract supply during downturns was too weak. Once confidence breaks, the death spiral makes recovery nearly impossible.
What does Seigniorage mean in DeFi?
Seigniorage means Profit from issuing stablecoins that cost less to create than their face value. The useful question is not only the definition, but how the mechanism changes risk, return, liquidity, or governance for the user.
How is Seigniorage used in practice?
A practical example: Basis Cash and Empty Set Dollar used seigniorage models: when the stablecoin traded above $1, new tokens were minted and distributed to holders, but both ultimately failed to maintain their pegs.
