“How ETFs Amplify the Global Financial Cycle in Emerging Markets”, with Nathan Converse and Eduardo Levy Yeyati.
Since the early 2000s exchange-traded funds (ETFs) have grown to become an important investment vehicle worldwide. In this paper, we study how their growth affects the sensitivity of international capital flows to the global financial cycle. We combine comprehensive micro-level data on investor flows with a novel identification strategy that controls for unobservable time-varying economic conditions at the investment destination. For the emerging market universe, we find that the sensitivity of investor flows to global risk factors for equity (bond) ETFs is 1.5 (1.25) times higher than for equity (bond) mutual funds. In turn, we show that countries where ETFs hold a larger share of financial assets are significantly more sensitive to global risk factors, both in terms of total equity flows and prices. We conclude that the growing participation of ETFs amplifies the incidence of the global financial cycle in emerging markets.
