Abstract

This paper investigates the impact of growing ownership of fixed-income ETFs and mutual funds on the commonality in liquidity across corporate bonds. The unpredictability of liquidity demands inherent in these funds can prompt correlated trading among underlying illiquid bonds. The empirical results reveal a positive and significant relationship between ETF ownership and liquidity commonality in investment-grade bonds, indicating that ETFs curtail opportunities for liquidity risk diversification. Conversely, mutual fund ownership does not impact bond liquidity co-movement, a feature that distinctly differentiates it from equity markets. The paper identifies three pivotal mechanisms that help explain the disparate impact of ETFs and mutual funds: correlated trading stimulated by fund flows, differences in investor clienteles, and the influence of ETF arbitrage activity.
