First, we show that FX liquidity can be accurately measured with daily and readily-available data. Second, we demonstrate that FX liquidity declines with funding constraints and global risk, supporting theoretical models relating funding and market liquidity. In these distressed circumstances, liquidity tends to evaporate more for developed and riskier currencies. Finally, we show stronger comovements of FX liquidities in distressed markets, especially when funding is constrained, volatility is high, and FX speculators incur losses.enexchange ratesliquiditytransaction costscommonalitylow-frequency dataworking paper
