Adverse Selection Costs
Adverse selection costs represent the expected loss a liquidity provider incurs when trading with someone who has better information. These costs are a component of the total transaction cost for market makers.
Because the market maker is effectively providing a free option to the market, they must charge a premium in the form of a spread to remain profitable. If the market moves against the provider immediately after a fill, they have been adversely selected.
In the cryptocurrency sector, these costs are particularly high during periods of high volatility or when major news events occur. Measuring these costs is vital for determining the appropriate spread for a given liquidity provision strategy.
It is a critical metric for assessing the true cost of liquidity. Understanding these costs allows for more precise strategy optimization.
