Globalization and the Reach of Multinationals Implications for Portfolio Exposures, Capital Flows, and Home Bias

Abstract

The growing use of low-tax jurisdictions as locations for firm headquarters, proliferation of offshore financing vehicles, and growing size, number, and geographic diversity of multinational firms have clouded the view of capital flows and investor exposures from standard sources such as the IMF Balance of Payments and the Coordinated Portfolio Investment Survey. We use detailed, security-level information on U.S. cross-border portfolio investment to uncover the extent of distortions in the official U.S. statistics. We find that nearly a third of U.S. cross border portfolio investment is allocated to a country different from its primary economic exposure by standard reporting conventions. About one-fourth of the stock of global cross-border portfolio investment is similarly distorted, with exposures to emerging markets likely understated by about a third. Estimates of the international exposures of U.S. investors are even larger when we distribute exposure according to the geographic distributions of firm-level sales. Our results have implications for conclusions we draw about the factors influencing capital flows, in particular those to emerging markets.
