Capital Controls in Emerging and Developing Economies and the Transmission of U.S. Monetary Policy

Emerging markets and developing economies (EMDEs) exhibit significantly greater volatility in asset returns than advanced economies. The commonalities in these returns (and flows) across countries are particularly strong for EMDEs. If these occur independently of the exchange rate regime and if these global financial cycle effects are furthermore independent of countries’ financial openness, the result is Obstfeld (2022)’s “Lemma”: countries can do nothing to decouple from the global financial cycle. Under the prevalent view that U.S. monetary policy is the key driver of the global financial cycle, countries then inherit U.S. monetary policy no matter what they do on exchange rates or capital control policies. Using structural vector autoregression models for 78 countries over 1995–2019, as well as different methods of identifying U.S. monetary policy shocks from the literature, this paper tests the proposition that countries with less open capital accounts exhibit systematically smaller responses to U.S. monetary policy shocks than low capital control countries. This paper also considers the role of other institutional features such as exchange rate regimes and foreign exchange interventions in explaining cross-country differences in the responses to the shocks. The empirical results suggest that more stringent capital controls exhibit smaller responses of interest rates and exchange rates to U.S. monetary policy shocks and that this result holds more firmly for EMDEs than advanced economies. In contrast, the analysis finds only weak evidence that the degree of exchange rate flexibility affects U.S. spillovers to foreign interest rates and exchange rates.
