Adverse Selection

Adverse Selection is a situation where one party in a transaction has better information than the other, leading to an unfair outcome for the less-informed party. In financial markets, this occurs when liquidity providers trade against informed participants who know the asset is mispriced.

The liquidity provider essentially sells too low or buys too high, suffering a loss when the market price adjusts to the informed participant's information. This is a central problem in market microstructure, as it forces providers to demand a premium for their services.

In crypto, this is frequently seen when decentralized exchanges are exploited by traders using off-chain data to trade against stale on-chain prices. To mitigate this, protocols implement mechanisms like time-weighted average pricing or circuit breakers.

Adverse selection is a key component of market inefficiency and risk management. It highlights the importance of information parity in maintaining fair and orderly markets.
