内容简介:

Liquidity can evaporate quickly during market turmoil. This paper proposes a nonlinear rational expectations equilibrium model of high-frequency endogenous liquidity provision to understand better such fragile liquidity. With fast trading speed and private information, high-frequency traders (HFTs) can either compete with designated market makers (DMMs) by providing liquidity, or attempt to profit from speculative trades that consume liquidity. Absent an obligation to provide liquidity, HFTs can switch between supplying and consuming liquidity, depending on their beliefs. The risk from HFTs’ endogenous liquidity provision, coupled with limits to participation by DMMs, intensifies the adverse selection faced by DMMs. This can generate a gap between liquidity supply from DMMs and liquidity demand by informed traders. As a result, endogenous liquidity provision produces fragile liquidity, with the possibility of market crashes when HFTs switch from liquidity provision to liquidity consumption in extreme times.
