Foreign capital inflows into the United States reached $199.8 billion in August 2026, more than doubling from a revised $87.4 billion in July, as overseas investors sharply increased purchases of long-term American securities despite reducing their exposure to short-term assets.
The U.S. Treasury’s report, released Friday, October 16, showed net foreign purchases of long-term U.S. securities totaling $300.7 billion. Foreign holdings of Treasury bills, however, declined by $47.8 billion, highlighting a divergence between longer-term securities demand and short-term investment flows.
The overall $199.8 billion figure represents net Treasury International Capital (TIC) inflows, combining long-term securities transactions, short-term securities and custody liabilities, and banking flows.
According to the Treasury’s August TIC tables, private foreign investors accounted for $178.5 billion of total net inflows, while foreign official institutions contributed $21.3 billion.
Foreign Investment Accelerates Sharply
August marked a substantial recovery in net capital inflows from July, when the Treasury initially reported $83.7 billion. The latest data revise July’s total upward to $87.4 billion, meaning August inflows increased by $112.4 billion on a comparable basis, according to Investozora’s calculation.
Private foreign inflows rose from a revised $76.5 billion in July to $178.5 billion in August, while official inflows increased from $10.9 billion to $21.3 billion. The stronger August reading was particularly evident in long-term U.S. securities.
Foreign investors purchased a net $300.7 billion in domestic long-term securities, compared with $40.6 billion in July. Private investors accounted for $257.8 billion of August purchases, while foreign official institutions purchased $42.9 billion.
Within the private-investor category, net purchases of U.S. equities totaled $131.9 billion, reversing net sales of $10.6 billion in July. Private foreign purchases of Treasury bonds and notes reached $90.9 billion, following net sales of $29.1 billion the previous month. Corporate bonds attracted another $36.8 billion in net private purchases.
The rise in foreign demand for longer-term government debt is relevant to investors tracking Treasury yields, although the TIC figures alone cannot establish how those purchases affected market interest rates.
Short-Term Holdings Decline
The broader inflow masked substantial reductions in shorter-term foreign holdings. Foreign investors reduced their Treasury bill positions by $47.8 billion in August, reversing a $39.0 billion increase in July.
Foreign official institutions accounted for $42.2 billion of the August Treasury bill reduction, while private foreign investors accounted for $5.6 billion.
Across all dollar-denominated short-term U.S. securities and other custody liabilities, foreign holdings declined by $37.8 billion, compared with an increase of $65.2 billion in July. Banks’ own net dollar-denominated liabilities to foreign residents also decreased by $41.6 billion, reversing a $50.1 billion increase in July.
These withdrawals partly offset the substantial long-term securities inflows, explaining why the overall net capital inflow was smaller than the headline figure for foreign purchases of long-term U.S. assets.
The divergence is also relevant to the broader U.S. financial system, where changes in the composition of foreign funding can matter for bank liquidity and financial conditions. However, TIC banking liabilities are not equivalent to the bank reserves reported on the Federal Reserve’s balance sheet.
Long-Term Securities Drive Inflows
U.S. residents also increased their investments in overseas securities during August, purchasing a net $21.6 billion in long-term foreign assets. Those purchases reduced the net long-term capital inflow into the United States, although they were considerably smaller than the $68.5 billion purchased by U.S. residents in July.
After incorporating U.S. transactions in foreign securities and the Treasury’s applicable adjustments, net foreign acquisitions of long-term securities totaled $279.2 billion in August. That compares with a net outflow of $27.9 billion in July.
The distinction matters because the $300.7 billion figure measures foreign purchases of long-term U.S. securities, while the $279.2 billion figure reflects the broader net long-term securities flow after accounting for transactions in foreign securities by U.S. residents and other adjustments.
Combining August’s $279.2 billion long-term inflow with the $37.8 billion reduction in short-term holdings and the $41.6 billion decrease in banking liabilities produces the reported $199.8 billion overall inflow.
For investors examining the relationship between global investment demand and domestic financing conditions, the results also provide context for understanding the Federal Reserve’s monetary policy, although international portfolio flows do not independently determine the central bank’s interest-rate decisions.
What the Data Reveal
The latest numbers provide evidence of strong cross-border demand for U.S. financial securities during August, particularly equities and longer-maturity debt instruments.
They do not, however, establish why individual investors changed their portfolios or demonstrate that foreign capital flows directly caused subsequent movements in Treasury yields, stock prices or the dollar.
The Treasury also cautions that its securities-holdings statistics rely substantially on custodial records. Assets held through financial intermediaries in third countries may not be attributed accurately to their ultimate owners.
Furthermore, TIC figures exclude direct investment flows, which are measured separately by the Bureau of Economic Analysis. The $199.8 billion reading therefore should not be interpreted as a comprehensive measure of every form of foreign investment entering the United States.
The composition of foreign demand remains relevant to the U.S. dollar and financial markets, but exchange rates also reflect interest-rate expectations, economic conditions and other factors beyond securities transactions.
For investors monitoring international demand for American assets, the next report will help establish whether August’s long-term securities buying persisted or represented a temporary increase.
The Treasury is scheduled to release September 2026 TIC data on November 18, 2026, providing the next official assessment of foreign securities transactions and related banking flows.
