On one hand, tighter risk management reduces the maximum position an institution can take, thus the amount of liquidity it can offer to the market. On the other hand, risk managers can take into account that lower liquidity amplifies the effective risk of a position by lengthening the time it takes to sell it. The main result of the paper is that a feedback effect can arise: tighter risk management reduces liquidity, which in turn leads to tighter risk management, etc. This can help explain sudden drops in liquidity and, since liquidity is priced, in prices in connection with increased volatility or decreased risk-bearing capacity.
