This paper studies short-term liquidity withdrawal in the FX spot market for eight currency pairs. We include over 3 million limit order submissions, worth more than $5 trillion, and investigate the drivers of two different measures of volume-based liquidity. Overall, we find that market participants react differently to changes in the state of the market for different currency pairs. Moreover, the liquidity withdrawal process also differs depending on the perceived information content of new limit orders submitted. Finally, we document that a 'liquidity illusion' might exist in FX spot markets electronic trading platforms where algorithmic and high-frequency trading is prominent. Highlights FX spot markets react very differently to changes in the state of the market. The perceived information content of new limit order submissions is important. Order-splitting strategies appear successful but could be detrimental to the market. A 'liquidity illusion' seems to exist in the electronic FX spot market. This has implications for market participants and policymakers.
