Hedge funds using Lehman as prime broker could not trade after the bankruptcy, and these funds failed twice as often as otherwise-similar funds after September 15 (but not before). Stocks traded by the Lehman-connected hedge funds in turn experienced greater declines in market liquidity following the bankruptcy than other stocks; and, the effect was larger for ex ante illiquid stocks. We conclude that shocks to traders’ funding liquidity reduce the market liquidity of the assets that they trade. ER -
