This paper explores commonality in liquidity for country ETFs. Using data from 21 country ETFs, the empirical results present the strong commonality in liquidity among country ETFs. Furthermore, the paper shows that the magnitude of commonality in liquidity for country ETFs varies with the liquidity distribution. The empirical results also indicate that the extent of liquidity commonality for country ETFs is stronger in times of financial crisis than in non-crisis periods. Finally, the paper also finds that the impacts of supply- and demand-side effects on commonality in liquidity for country ETFs vary with liquidity distributions, and the results are consistent with the funding-liquidity mechanism and investor sentiment hypotheses.
