# Prime Cash Supply Caps Notional's governance can set Prime Cash supply caps that effectively limit the maximum amount of Prime Cash that can be minted in a given currency. Governance can set the `maxUnderlyingSupply` for all listed currencies. The `maxUnderlyingSupply` sets the maximum amount of Prime Cash that can be minted based on a value in underlying terms. Supply caps are important because they can put a practical limit on the total value of a given currency that can be used as Prime Cash collateral. This allows Notional's governance to be able to list less liquid assets in a capital-efficient manner by limiting the protocol's exposure. ### Parameter selection considerations When setting Prime Cash supply caps, Notional's governance should consider the asset's on-chain liquidity profile and the demand from Notional users for that asset. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
