The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.
This paper analyzes various indicators of the U.S. international investment position from a portfolio perspective. The 1990s saw a decline in home bias, which, coupled with rapid financial deepening, led to a large increase in gross international investment holdings. The home bias of non-U.S. investors declined more rapidly than that of U.S. investors, allowing the United States to finance a rising stock of net liabilities, even as foreign portfolios remained marketweight or underweight U.S. assets in each investment category. However, a comparison to other countries reveals that the U.S. net international investment position (NIIP) is large given the size of the economy and is deteriorating, especially through a growing negative net debt securities position.
