Our new analysis shows that foreign investors owned about 40 percent of US corporate equity in 2019, up substantially over the last few decades. Retirement accounts of US households owned about 30 percent in 2019, and the taxable accounts of US investors owned about 25 percent, which is most of the rest.
In recent years, the foreign share of US corporate equity has ballooned, as reflected in data from the financial accounts of the US from the Federal Reserve (the “Fed”).
7 Foreigners held just 4 percent of US equity in 1986, but their share rose steadily to 11 percent by 1980, 25 percent by 2000, and 40 percent today.
