The impact of monetary policy in large advanced countries on emerging market economies—dubbed spillovers—is hotly debated in global and national policy circles. When the U.S. resorted to unconventional monetary policy, spillovers on asset prices and capital flows were significant, though remained smaller in countries with better fundamentals. This was not because monetary policy shocks changed (in size, sign or impact on stance). In fact, the traditional signaling channel of monetary policy continued to play the leading role in transmitting shocks, relative to other channels, affecting longer-term bond yields. Instead, we find that larger spillovers stem more from structural factors, such as the use of new instruments (asset purchases). We obtain these results by developing a new methodology to extract, separate, and interpret U.S. monetary policy shocks.

When the U.S. economy sneezes, do emerging markets catch a cold? We show that economic news, and not just monetary policy, in the United States affects financial conditions in emerging markets. News about U.S. employment has the strongest effects, followed by news about economic activity and about vaccines during the COVID-19 pandemic. News about inflation has instead limited effects on average. A key channel of international transmission of U.S. economic news appears to be the risk perceptions or risk aversion of international investors. We also show that some of the transmission of U.S. economic news occurs independently of the U.S. monetary policy reaction. Finally, we expand on evidence that financial conditions in the U.S. and emerging markets respond differently to U.S. monetary policy surprises, depending on the reaction of US stock prices.

We examine three main channels through which U.S. monetary policy shocks affect firm investment in foreign countries: (1) the balance sheet channel; (2) the financial channel of the exchange rate; and (3) the trade channel. For this purpose, we use quarterly firm-level data for 63 advanced economies (AEs) and emerging market and developing economies (EMDEs) over 1996-2016. Our results suggest an important and independent role for all three key channels. U.S. monetary policy shocks have larger effects on investment for firms that are more leveraged (balance sheet channel), for firms that have a higher share of debt in foreign currency (financial channel of the exchange rate), and for firms that operate in sectors with higher export dependence (trade channel). Back-of-the-envelope calculations suggest that the balance sheet channel is the most important channel of transmission of U.S. monetary policy shocks on aggregate firm investment.

This report analyzes the possible spillover effects that could result if the U.S. normalizes its monetary policy while euro area countries are increasing monetary stimulus (a situation referred to as asynchronous monetary conditions). This analysis identifies country-specific shocks to economic activity and monetary conditions since the early 1990s, finding that real and monetary conditions in the United States and the euro area have oftentimes been asynchronous and have often resulted in significant spillover effects, particularly since early 2014.

Recent changes in technology, along with the opening up of many regions previously closed to investment, have led to explosive growth in the international movement of capital. Flows from foreign direct investment and debt and equity financing can bring countries substantial gains by augmenting local savings and by improving technology and incentives. Investing companies acquire market access, lower cost inputs, and opportunities for profitable introductions of production methods in the countries where they invest. But, as was underscored recently by the economic and financial crises in several Asian countries, capital flows can also bring risks. Although there is no simple explanation of the currency crisis in Asia, it is clear that fixed exchange rates and chronic deficits increased the likelihood of a breakdown. Similarly, during the 1970s, the United States and other industrial countries loaned OPEC surpluses to borrowers in Latin America. But when the U.S. Federal Reserve raised interest rates to control soaring inflation, the result was a widespread debt moratorium in Latin America as many countries throughout the region struggled to pay the high interest on their foreign loans. International Capital Flows contains recent work by eminent scholars and practitioners on the experience of capital flows to Latin America, Asia, and eastern Europe. These papers discuss the role of banks, equity markets, and foreign direct investment in international capital flows, and the risks that investors and others face with these transactions. By focusing on capital flows' productivity and determinants, and the policy issues they raise, this collection is a valuable resource for economists, policymakers, and financial market participants.
