Collateral Asset Depth

Collateral asset depth measures the volume of buy and sell orders available at various price levels for an asset used as security for a loan or derivative position. In the context of DeFi and derivatives, high depth implies that a large amount of the asset can be bought or sold without causing significant price movement.

Protocols rely on this depth to ensure that if a user's position needs to be liquidated, the asset can be sold quickly without causing a massive price drop that would result in bad debt for the protocol. If an asset has low depth, it is considered riskier collateral because it is more susceptible to price manipulation and high slippage during liquidation.

Therefore, protocols often apply stricter haircut scaling or limit the use of low-depth assets as collateral.
