Reserve assets are assets held within a stablecoin arrangement to support the value of outstanding tokens and the issuer's ability to meet redemption obligations.
For fiat-backed stablecoins, reserve assets can include bank deposits, short-term government securities, reverse repurchase agreements, and other liquid financial instruments. Their market value alone does not determine the strength of the reserve. Credit quality, duration, liquidity, currency matching, custody, legal segregation, and the speed at which assets can be converted into redemption proceeds also matter. Regulatory standards increasingly focus on both the quantity and quality of reserves.
Reserve assets are associated most directly with issuer-backed arrangements. Collateral is a broader term that can also describe assets pledged or locked in decentralized stablecoin systems.
Reserve quality and liquidity influence whether an issuer can meet large redemption requests without forced sales, delays, or losses.
A dollar stablecoin reserve can hold bank deposits and short-dated US Treasury securities to provide assets for dollar redemptions.
