Title: The National Debt of the United States: An Overview of Its Growth and Composition

Introduction

The national debt of the United States represents the financial obligations owed by the federal government to its creditors. From its inception, America has carried some form of national debt, with each subsequent president contributing to its expansion. However, the steepest increase occurred since 2008, due to a combination of government spending and tax revenue shortfalls [1].

As of May 2025, the total national debt has surpassed $36.2 trillion, marking a significant jump in the nation's outstanding financial obligations [2]. The government funds its spending primarily through personal and corporate income taxes, payroll taxes, and borrowing. The Treasury then channels this money into programs such as Social Security, healthcare, education, infrastructure, and national defense. When the government spends less than its tax revenue, a budget surplus arises; otherwise, a budget deficit results, leading to increased borrowing [3].

Key Takeaways

• The current national debt in the United States is over $36.2 trillion, demonstrating the growing financial commitments of the federal government. (2025 May)
• Military spending, stimulus programs, and increased public sector expenditure contribute to a spike in the national debt.
• The debt-to-GDP ratio provides insight into a nation's ability to repay its debt obligations.
• The U.S. frequently encounters its debt ceiling, requiring adjustments or temporary suspensions to avoid default.

Understanding the National Debt

The federal government resorts to borrowing to cover unpaid bills that accumulate over time. When the government spends more than it collects through taxes, a budget deficit arises, necessitating further borrowing to settle the shortfall. The U.S. Treasury issues bonds, bills, and notes to both domestic and foreign investors to raise funds [3].

The national debt consists of borrowed funds, including the interest charged on these securities. The U.S. government's debt is popular among investors due to its safety and liquidity.

Growing National Debt

Since its founding, the United States has accrued debt, amassing over $75 million during the Revolutionary War, which escalated to over $2 billion by the close of the Civil War in 1865 [3]. Significant economic and political events, such as wars and recessions, often trigger an increase in the national debt. For instance, the wars in Afghanistan and Iraq, the Great Recession, and the COVID-19 pandemic have all contributed to a rise in U.S. debt levels [3].

The increased spending during military conflicts, as well as relief measures in times of economic turmoil, significantly widens the federal deficit and contributes to the debt's escalation. For example, President Obama's American Recovery and Reinvestment Act, a fiscal stimulus package amounting to $831 billion, aimed at restoring jobs during the 2008 recession [5].

Debt-to-GDP Ratio

The debt-to-GDP ratio, which compares a country's public debt to its gross domestic product (GDP), serves as a useful gauge of a nation's economic health. A higher debt-to-GDP ratio suggests that the country may struggle to repay its debt and faces a higher risk of default. As of the end of 2024, the U.S. debt-to-GDP ratio stood at 121.85% [8].

Types of Debt Comprising the National Debt

1. Marketable and Non-marketable Securities: Marketable securities like Treasury bills, bonds, notes, and Treasury Inflation-Protected Securities (TIPS) are tradeable on the secondary market, while non-marketable securities such as savings bonds can't be sold to other investors [3].
2. Debt Held by the Public: Domestic and foreign entities, such as individuals, corporations, state and local governments, Federal Reserve banks, foreign investors, and governments hold approximately 74% of the U.S. national debt outside the federal government [1].
3. Intragovernmental Debt: Intragovernmental debt arises when one part of the government owes money to another. It is primarily driven by the Surplus in Government Trust Funds invested in Treasury securities [3].

Tracking, Maintaining, and Managing the National Debt

The Bureau of the Fiscal Service is responsible for accounting, reporting, and payment management for the federal government, including tracking and reporting debt levels [11]. The interest expenses linked to the national debt have been relatively stable in recent years, thanks to low interest rates, although increased interest rates can substantially elevate the costs of maintaining such debt levels [10]. The Treasury's goal is to ensure the lowest possible cost of borrowing over time by offering attractive and liquid securities [11].

The Debt Ceiling

The debt ceiling, or the debt limit, marks the maximum amount that the U.S. government is permitted to borrow by issuing bonds. If the debt reaches this limit, the Treasury must seek alternative means to pay expenses to prevent default, necessitating an increase in the debt ceiling by Congress [3].

Conclusion

The national debt represents the total financial commitments of the United States government to its creditors. A variety of economic and political events contribute to its growth, with military spending and relief measures during times of economic distress being significant factors. Understanding the debt's composition, balancing it against economic growth, and effectively managing it are essential to the long-term stability of the U.S. economy.

In the realm of finance and business, the growth of the national debt in the United States has been fueled not only by government spending but also by the issuance of specific financial instruments such as tokens in Initial Coin Offerings (ICOs) and digital assets in the Decentralized Finance (DeFi) sector. For instance, the government could potentially use DeFi protocols to borrow funds in the form of non-fungible or stable coins. Furthermore, investments in DeFi and digital tokens could serve as alternative sources of revenue, bolstering the government's efforts to manage its debt obligations.
