Washington – The findings from the annual survey of U.S. portfolio holdings of foreign securities at year-end 2019 were released today and posted on the Treasury web site at https://www.treasury.gov/resource-center/data-chart-center/tic/Pages/shcreports.aspx
The survey was undertaken jointly by the U.S. Department of the Treasury, the Federal Reserve Bank of New York, and the Board of Governors of the Federal Reserve System.
A complementary survey measuring foreign holdings of U.S. securities is also conducted annually. Data from the most recent such survey, which reports on securities held at end-June 2020, are currently being processed. Preliminary results are expected to be reported on February 26, 2021.
This survey measured the value of U.S. portfolio holdings of foreign securities at year-end 2019 as approximately $13.1 trillion, with $9.5 trillion held in foreign equity, $3.1 trillion held in foreign long-term debt securities (original term-to-maturity in excess of one year), and $0.5 trillion held in foreign short-term debt securities. The previous such survey, conducted as of year-end 2018, measured U.S. holdings of approximately $11.3 trillion, with $7.9 trillion held in foreign equity, $2.9 trillion held in foreign long-term debt securities, and $0.5 trillion held in foreign short-term debt securities. The increase in 2019 was mainly in equity (see Table 1).
U.S. portfolio holdings of foreign securities by country at the end of 2019 were the largest for the Cayman Islands ($2.00 trillion), followed by the United Kingdom ($1.52 trillion), Japan ($1.15 trillion), and Canada ($1.10 trillion) (see Table 2). These four countries attracted 44 percent of total U.S. portfolio investment, versus 45 percent the previous year.
The surveys are part of an internationally coordinated effort under the auspices of the International Monetary Fund (IMF) to improve the measurement of portfolio asset holdings.

 The stock of foreign securities for December 31, 2019, reported in this survey may not, for a number of reasons, correspond to the stock of foreign securities on December 31, 2018, plus cumulative flows reported in Treasury’s transactions reporting system.
