Who Owns Us Debt

The US national debt is owed to a broad mix of domestic and foreign investors, government agencies, and the Federal Reserve itself. Americans and US institutions hold the overwhelming majority — roughly 76% — while foreign governments and private investors account for about 24%.

As of December 2025, the total gross national debt stands at approximately $38.4 trillion, a figure that has grown by more than $2 trillion in a single year. The debt has become one of the most discussed fiscal concerns in Washington, not only because of its sheer size but because of the rapid pace at which it continues to expand. Understanding who owns it — and what that means — is essential to making sense of current economic and political debates.

For a broader look at how economists visualize the scale of the US national debt in everyday terms, context matters as much as the raw numbers.

Who Owns US Debt?

The national debt is divided into two main categories: debt held by the public and intragovernmental debt. Debt held by the public includes Treasury securities purchased by individuals, mutual funds, banks, pension funds, state and local governments, and foreign entities. Intragovernmental debt refers to funds the federal government owes to its own trust funds, primarily Social Security and Medicare.

Domestic Holders

Private investors hold the largest share. As of early 2025, domestic private investors collectively hold around $24.4 trillion, making them by far the most significant creditors. Within that group, mutual funds are among the largest, holding close to $4.5 trillion. Banks and similar financial institutions account for roughly $1.9 trillion, and state and local governments hold about $1.7 trillion. Public and private pension funds together hold nearly $956 billion.

US Government Agencies

Federal trust funds represent a substantial block of intragovernmental holdings. The Social Security trust funds alone held nearly $2.7 trillion in special Treasury securities as of mid-2025. Military retirement funds held more than $2.2 trillion, and Medicare’s two trust funds held a combined $425 billion. These holdings reflect money the government technically owes itself, but they remain real obligations that will need to be paid out as beneficiaries claim their benefits.

The Federal Reserve’s Role

The Federal Reserve also holds a significant portion of the national debt through its bond-purchasing programs. During the COVID-19 pandemic, the Fed dramatically expanded its balance sheet to stabilize financial markets. While it has since wound down its quantitative easing program, it retains a large portfolio of Treasury securities, making it one of the country’s largest individual creditors.

Largest Shareholders of US Debt: Foreign Holders

Foreign entities — governments and private investors combined — hold roughly $8.5 trillion of the national debt, which represents about 24% of the total. That share is spread across dozens of countries, meaning no single foreign nation holds enough to meaningfully control or destabilize the market. The top three foreign holders as of 2025 are Japan, the United Kingdom, and China.

Japan: The Largest Foreign Creditor

Japan has been the largest foreign holder of US Treasury securities for many years. As of May 2025, Japan holds more than $1.13 trillion, or about 3.1% of the total national debt. Japanese institutional investors — including insurance companies and pension funds — have long favored US Treasuries for their stability and yield, particularly compared to domestic Japanese government bonds which have historically offered near-zero returns.

United Kingdom

The United Kingdom holds approximately $807–809 billion in US debt, making it the second-largest foreign creditor. London’s role as a major global financial center means that a significant portion of these holdings may represent funds managed on behalf of third-party investors in other countries, rather than direct government investments.

China: A Declining Presence

China, once the second-largest foreign holder, has steadily reduced its Treasury holdings over the past several years. As of mid-2025, China holds approximately $756–757 billion. This gradual liquidation — which reflects both geopolitical tensions and China’s effort to diversify its foreign reserves — has not produced significant market disruption, a sign of how broad and deep the US Treasury market remains. For context on how the relationship between China and the US economy continues to evolve, the rise of homeland economics and economic decoupling has played a meaningful role in this strategic shift.

Other Notable Holders

Beyond the top three, several other countries hold meaningful positions. The Cayman Islands — primarily through hedge funds domiciled there — holds about $448 billion. Belgium and Luxembourg, both significant financial hubs for European funds, each hold over $410 billion. Canada holds approximately $368 billion, and France and Ireland each hold between $340 and $360 billion. Taiwan, Singapore, and Hong Kong each account for roughly $247–299 billion, reflecting the deep integration of Asian financial markets with US sovereign debt.

History of US Debt: Origins and Growth

The United States has carried public debt since its founding. The country’s first debt was incurred during the Revolutionary War, when the Continental Congress borrowed heavily to finance the fight for independence. By the time Alexander Hamilton became the first Secretary of the Treasury in 1789, the new nation owed roughly $75 million to domestic and foreign creditors.

Early Institutional Framework

Hamilton championed the assumption of all state war debts by the federal government, a decision that established the principle of full faith and credit behind US obligations. This made American debt credible to foreign investors from the outset. The First Bank of the United States, chartered in 1791, provided early infrastructure for managing and distributing government securities, laying the groundwork for the Treasury market that exists today.

Debt Through Major Historical Events

Public debt has historically spiked during wars and crises. The Civil War pushed debt from under $90 million in 1861 to nearly $2.8 billion by 1866. World War I and World War II produced even larger surges, with WWII debt reaching approximately 106% of GDP — a level that remains the historical high-water mark. The debt declined significantly during the postwar economic boom of the 1950s and 1960s but began a sustained rise again during the stagflation era of the 1970s.

The Modern Debt Trajectory

Since 2002, the federal government has run a deficit every single fiscal year without exception. The 2008 financial crisis, the 2017 tax cuts, and the COVID-19 pandemic each contributed to significant debt increases. Pandemic-era spending alone added trillions within a matter of months. Debt crossed $30 trillion for the first time in February 2022, $34 trillion in January 2024, $36 trillion in November 2024, and reached $38 trillion in October 2025. The trajectory shows no sign of reversing under current policy, with generational financial pressures on younger Americans compounding long-term fiscal challenges through reduced tax base growth and higher social spending demands.

Key Institutions That Manage US Debt

Unlike a corporation with a board of directors, the national debt is managed through a network of government institutions, each with defined roles in issuing, regulating, and servicing the debt. These bodies collectively determine how the debt is structured, priced, and repaid.

US Department of the Treasury

The Treasury Department is the primary institution responsible for issuing and managing federal debt. It does this through the Bureau of the Fiscal Service, which operates the Debt to the Penny dataset and oversees all Treasury securities auctions. The Treasury Secretary — currently Scott Bessent — plays a central role in setting issuance strategy. The Treasury has indicated a preference for issuing more short-term bills rather than increasing longer-term auction sizes, a strategy that can manage near-term market disruption while leaving long-term rate pressures largely intact.

The Federal Reserve

The Federal Reserve does not directly manage the national debt, but its monetary policy decisions profoundly influence how expensive that debt becomes to service. When the Fed raises interest rates, the cost of rolling over Treasury debt increases. The average interest rate on all federal debt stood at approximately 3.38% as of late 2025 — more than double the 1.56% level from January 2022, before the Fed began its aggressive tightening cycle. The Federal Open Market Committee (FOMC) sets the federal funds rate, while the Board of Governors provides oversight of the system.

Congressional Budget Office (CBO)

The CBO serves as Congress’s independent fiscal scorekeeper. It produces regular projections of the national debt trajectory and evaluates the fiscal impact of proposed legislation. CBO projections have consistently shown debt on an upward path, with publicly held debt forecast to rise from roughly 99% of GDP in 2024 toward 116% by 2034. These projections inform policy debates but carry no enforcement authority.

Government Accountability Office (GAO)

The GAO monitors the government’s overall fiscal health and releases annual assessments on the nation’s debt trajectory. In its most recent analysis, the GAO projected that publicly held debt could reach 200% of GDP by 2047 if current policies remain unchanged — a trajectory it has repeatedly described as unsustainable. The GAO has called on Congress to develop a comprehensive fiscal strategy, though no such plan has been formally adopted. These fiscal challenges extend beyond government institutions and are reshaping how businesses approach economic planning, with domestic economic policy and fiscal constraints increasingly intersecting in ways that affect private sector investment decisions.

Social Security Administration and Other Trust Fund Managers

Federal trust fund managers — including those overseeing Social Security, Medicare, and military retirement funds — are significant holders of intragovernmental debt. These agencies hold special non-marketable Treasury securities and are, in effect, internal creditors of the federal government. Their growing claim on future revenues is one of the principal drivers of long-term debt growth, as an aging US population continues to increase benefit payouts faster than revenue can cover them.
