FRM Part II · FRM Exam Part II · Liquidity Risk

Which statement best describes exogenous versus endogenous liquidity risk in the context of bid-ask spreads?

Exogenous liquidity risk is market-wide and reflected in the quoted spread, beyond any single trader's control. Endogenous liquidity risk comes from the price impact of a trader's own large position or order, which the quoted spread does not capture for big trades.
