The United States is facing mounting pressure from a financial imbalance that economists say has quietly expanded over decades. Researchers at the Federal Reserve Bank of New York warned this week that foreign investors now hold nearly $69tn in US assets, a figure that is increasingly weighing on the country’s international income position and capital flows.
The warning reflects a sharp shift in America’s long-standing advantage as the world’s largest reserve currency issuer. For years, the US was able to maintain large deficits while still earning more from overseas investments than it paid out to foreign holders of American assets. According to the New York Fed, that advantage has largely disappeared over the past two years as rising interest rates and soaring US asset prices increase payments flowing abroad.
Foreign Ownership of US Markets Reaches Record Levels
The New York Fed estimates that US investors currently own around $41tn in overseas assets, leaving the country with a negative net international investment position of roughly $28tn. That gap has widened dramatically since 2019, increasing by approximately $16tn over the period.
Economists pointed to two major drivers behind the deterioration. The first is the persistence of US trade deficits. The country has imported more goods and services than it exports for more than half a century, forcing the economy to rely on foreign capital to bridge the difference. Since 2019, foreign investors acquired about $11tn in US assets, compared with roughly $6tn spent by American investors abroad.
The second factor is Wall Street itself. Foreign institutions and governments hold a substantial share of US equities, including stakes tied to major stock indexes and American companies. As US equity markets climbed over recent years, the value of those foreign-held positions surged as well.
Apollo Global Management chief economist Torsten Slok estimated that overseas investors now own about 18% of the US stock market, the highest level on record. According to the Fed’s calculations, rising market valuations alone reduced America’s net international investment position by another $10tn since 2019.
The shift also affects income flows. In 2019, the US still generated roughly $260bn more in overseas investment income than it paid out abroad. That surplus has now almost disappeared.
Higher Interest Rates Are Increasing Capital Outflows
The Federal Reserve’s aggressive rate increases after the pandemic added further strain to the balance sheet. Around $26tn of foreign-owned US assets are interest-bearing instruments such as Treasury securities, cross-border loans and deposits.
As rates climbed, so did the payments owed to overseas investors. Fed researchers found that about $170bn of the additional $240bn in net international payouts recorded since 2021 can be linked directly to higher interest rates.
The bank estimated that every percentage point increase in US interest rates now subtracts around $150bn from the country’s net investment income balance. Five years ago, the same rate move would have had a smaller effect because the foreign-owned debt load was lower.
The broader concern is that more profits, dividends and interest generated inside the US economy are now flowing overseas rather than remaining with domestic investors and institutions.
This issue has become increasingly relevant as international demand for US assets remains exceptionally strong. The International Monetary Fund has repeatedly highlighted the central role of dollar-denominated assets in global finance, particularly during periods of geopolitical instability and market stress. That demand has helped keep borrowing costs relatively manageable for Washington despite expanding debt levels.
Still, the growing foreign ownership of US markets leaves the country more exposed to shifts in investor sentiment and global capital allocation trends. Similar concerns emerged during previous periods of widening trade imbalances in the late 1980s and early 2000s, although the scale of today’s imbalance is substantially larger.
Why Economists Are Watching the Balance Sheet More Closely
The New York Fed’s analysis does not suggest an immediate financial crisis, but it does point to a structural challenge that may become harder to manage if deficits continue expanding.
The US economy has long relied on selling financial assets to overseas investors in exchange for imported goods and foreign capital. That arrangement worked smoothly while American investors consistently earned higher returns abroad than foreigners earned inside the US.
That margin has narrowed considerably. If interest rates remain elevated and foreign ownership of US equities continues to grow, economists say the cost of servicing America’s international liabilities could continue rising.
Investors and policymakers will now be watching whether future trade balances, market performance and monetary policy decisions deepen the gap further, or stabilise a balance sheet that has become increasingly dependent on foreign capital.
