The United States owes China money because China earns huge quantities of U.S. dollars selling goods to American consumers and businesses, and it recycles those dollars by buying U.S. government bonds. That is the short answer to why the U.S. owes China money. As of December 2025, China held roughly $683.5 billion in U.S. Treasury securities, making it the second-largest foreign creditor behind Japan.1U.S. Department of the Treasury. Table 5 – Major Foreign Holders of Treasury Securities That figure is smaller than the headlines suggest: it accounts for less than 2 percent of the total national debt, which stood at $38.86 trillion in early 2026.
The Trade Deficit Creates the Dollars
The debt relationship starts at the cash register. When Americans buy electronics, clothing, and industrial components made in China, dollars flow overseas. In 2024, the United States imported about $438.7 billion in goods from China and exported only $143.2 billion back, producing a goods trade deficit of roughly $295.5 billion.2U.S. Census Bureau. Trade in Goods with China Chinese exporters and their banks end up holding an enormous pile of dollars every year.
Those dollars have to go somewhere. Chinese financial authorities want to keep them in something safe, liquid, and interest-bearing, and U.S. Treasury securities fit all three requirements. The bigger the trade gap, the more dollars China accumulates, and the more incentive it has to move those dollars into American government bonds. The trade relationship and the debt relationship are two sides of the same transaction.
Why China Chooses U.S. Treasuries
China’s Treasury purchases are not charity or trust in American policy. The People’s Bank of China buys dollar-denominated assets as part of a deliberate strategy to manage the exchange rate between the yuan and the dollar. When the central bank soaks up dollars by purchasing Treasuries, it keeps demand for the dollar high and the yuan relatively weak. A weaker yuan makes Chinese exports cheaper for American buyers, which supports Chinese factories and jobs.
If the yuan strengthened too much, Chinese goods would cost more abroad, export growth would slow, and parts of China’s domestic economy would feel the strain. Treasury purchases do two jobs at once: they suppress the yuan, and they build a reserve of safe assets China can draw on during a financial crisis. The debt buildup is a byproduct of keeping the export machine running.
This currency management has drawn legal scrutiny. Under U.S. law, the Trade Facilitation and Trade Enforcement Act of 2015 requires the Treasury Department to monitor whether trading partners manipulate exchange rates to gain an unfair competitive advantage. U.S. officials have argued that deliberate currency undervaluation functions as an export subsidy because it effectively underprices Chinese goods. Whether it crosses into a prohibited subsidy under WTO rules is still unresolved, but it is the lens through which much of the political friction over Chinese debt purchases gets filtered.
How China Buys the Bonds
The Bureau of the Fiscal Service runs roughly 325 Treasury auctions each year to raise cash for federal operations and to refinance maturing debt.3Federal Reserve Financial Services. Treasury Auctions Foreign governments, including China, can participate alongside domestic banks, pension funds, and individual investors. Bidders submit the price they will pay or the yield they will accept, and the Treasury fills orders starting with the most favorable bids.
China also picks up Treasuries on the secondary market, where previously issued bonds trade among financial institutions. Those trades run through primary dealers, the 26 large banks that the Federal Reserve Bank of New York authorizes to trade directly with the Fed and to bid in every Treasury auction.4Federal Reserve Bank of New York. Primary Dealers Ownership changes are recorded electronically, and the Treasury Department tracks foreign holdings through its Treasury International Capital reporting system, which requires institutions with at least $50 million in cross-border transactions to file monthly reports.5U.S. Department of the Treasury.

How Much of the U.S. Debt China Actually Owns
China’s $683.5 billion in Treasury holdings sounds staggering until you see the whole picture. The total national debt was around $38.86 trillion in early 2026, split between $31.27 trillion in debt held by the public and $7.59 trillion in intragovernmental holdings. China’s share works out to less than 2 percent.
The biggest creditors are actually domestic. The Federal Reserve held about $4.3 trillion in Treasuries as of early 2026, and the Social Security trust funds held roughly $2.7 trillion at the end of 2024.6Social Security Administration. 2025 OASDI Trustees Report Commercial banks, mutual funds, state and local governments, and individual investors hold most of the rest. The idea that China “bankrolls” the U.S. government overstates Beijing’s role considerably.
Other Major Foreign Creditors
China isn’t even the largest foreign holder. Japan led the list at $1,185.5 billion in December 2025, and the United Kingdom held $866.0 billion. After that come several countries whose numbers reflect the world’s financial plumbing more than domestic wealth:1U.S. Department of the Treasury. Table 5 – Major Foreign Holders of Treasury Securities
- Belgium: $477.3 billion
- Canada: $468.1 billion
- Luxembourg: $435.1 billion
- Cayman Islands: $421.2 billion
- France: $368.9 billion
- Ireland: $340.7 billion
Belgium, Luxembourg, and the Cayman Islands appear on the list because they host custodial accounts and clearinghouses that manage investments on behalf of clients worldwide. The holdings attributed to those jurisdictions reflect where the bonds are held, not necessarily who ultimately owns them. Total foreign holdings across all countries came to roughly $9.27 trillion in December 2025, meaning foreigners as a group hold about a quarter of the national debt.
China Has Been Reducing Its Holdings for a Decade
The most important trend gets the least attention. China has been steadily selling down its Treasury holdings for years. In December 2016, China held $1,058.4 billion in U.S. debt, about 17 percent of all foreign-held Treasuries. By December 2025, that figure had dropped to $683.5 billion, or roughly 7 percent of foreign holdings.7U.S. Department of the Treasury. Major Foreign Holders of Treasury Securities China shed more than $370 billion in Treasuries over that period.
Several forces are behind the decline. China has been diversifying its reserves into other assets, including gold and bonds issued by other countries. Geopolitical tensions have made both sides warier of the entanglement. As China pulled back, the overall pool of foreign holders grew, and other buyers stepped in. The Treasury has had no trouble finding takers.
What Would Happen If China Sold Its Treasuries
The dramatic scenario is worth a clear look, because it is the fear that drives most conversations about the U.S. owing China money. If China rapidly sold hundreds of billions in Treasuries, the immediate effect would be a spike in bond yields. A flood of bonds on the market pushes prices down and yields up, because new buyers demand a higher return to absorb the supply. The 10-year Treasury yield sets the benchmark for mortgage rates, car loans, and corporate borrowing costs, so a sharp jump would ripple through the whole economy.
The damage would not be one-sided. A massive sell-off would weaken the dollar and strengthen the yuan, which is the opposite of what China’s export strategy requires. Chinese goods would get more expensive for American buyers, hurting the same factories the currency policy is designed to protect. Some analysts have argued that faster net export growth in the U.S. could partly offset the higher borrowing costs, since a weaker dollar makes American-made goods more competitive abroad.
The Federal Reserve also has tools to cushion the blow. It can buy Treasury securities on the open market to stabilize prices, and under Section 13(3) of the Federal Reserve Act it can deploy emergency lending programs during unusual and exigent circumstances, with Treasury Department approval.8Federal Reserve Board. Responding to Financial System Emergencies A Chinese sell-off would hurt China at least as much as it would hurt the United States, which is why most economists treat the scenario as a theoretical threat rather than a realistic one. The debt the U.S. owes China exists because the arrangement works for both sides, and unwinding it fast would work for neither.
