Understanding the National Debt of the United States

The national debt of the United States is a complex and ever-evolving figure that has captured the attention of economists, politicians, and citizens alike. It’s the total amount owed by the federal government to treasury security holders, including both public and intragovernmental debts. This staggering sum, currently standing at over $34 trillion as of February 2024, is a result of deficit years where spending exceeds revenue collection. But what exactly does this mean for you and me? And how did we get here?

The Components of the National Debt

Breaking down the national debt into its components can help us understand it better. The $26.5 trillion held by the public is a mix of Treasury notes, bills, and bonds owned by investors both domestic and foreign. Meanwhile, intragovernmental debt stands at $12.1 trillion, representing amounts owed to program beneficiaries like the Social Security Trust Fund.

When we talk about servicing this debt, it’s not just about paying interest; it also includes the annualized cost of $726 billion (or 14% of total federal spending). This is a significant portion of our budget and highlights why managing the national debt is so crucial for economic stability.

A Historical Perspective

The history of the United States’ public debt dates back to 1789, with its highest levels during Harry Truman’s term after World War II. The lowest point was under Richard Nixon in 1974. From there, it has seen sharp increases and decreases over the decades, driven by factors like wars, recessions, and economic policies.

Currently, the United States federal government anticipates a significant increase in its debt issuance for 2023, with net marketable debt expected to reach $425 billion. This is due to stagnant tax revenues and higher government spending, which are key drivers of this growth.

The Debt-to-GDP Ratio

One way to measure the national debt’s impact on the economy is through the debt-to-GDP ratio. As of March 6, 2025, it was approximately $29 trillion, representing about 77% of GDP in 2017. This means that for every dollar produced by the U.S. economy, a significant portion goes towards servicing this debt.

According to projections from the Congressional Budget Office (CBO), the ratio could reach nearly 100% by 2028 if certain policies are maintained. This underscores the urgency of addressing the national debt and its long-term implications for economic growth and fiscal sustainability.

The Impact on Future Generations

Intergenerational equity is a critical concern when it comes to the national debt. Young workers today face high unemployment rates, lower lifetime earnings, and an uncertain future due to job cuts and economic instability. The burden of this debt could potentially affect their financial well-being significantly.

The CBO projects that deficits will increase by $1.6 trillion over the 2018-2027 period, resulting in a total debt increase of $11.7 trillion during this time. This means each household would see an additional $12,700 in debt by 2028.

Foreign Ownership and Risks

A significant portion of the public debt is held by foreign governments and investors. As of October 2018, foreigners owned approximately $6.2 trillion of US debt, with Japan ($1.2 trillion) and China ($1.1 trillion) being the top holders. This raises concerns about potential risks to economic stability if these countries were to sell off their holdings.

While the U.S. has never fully defaulted on its debt, there are risks associated with rising debt levels, including reduced output, discouraged work, and restrictions on fiscal policy. These factors highlight the importance of sustainable fiscal policies and prudent management of the national debt.

The Role of Interest Rates

Negative real interest rates have been used to obtain low rates on government debt, saving taxpayer money and improving creditworthiness. However, as we saw in October 2023 when yields for 10-year Treasury notes breached 5%, this can affect homebuyers and corporations.

The cost of servicing the US national debt is projected to more than triple by 2024, reaching 3.0% of GDP. This means that interest payments will exceed those on national defense, highlighting the growing burden of debt service costs.

Conclusion

The national debt of the United States is a multifaceted issue with far-reaching implications for economic stability and future generations. As we navigate this complex landscape, it’s crucial to consider both the immediate financial impacts and long-term consequences. The path forward requires careful fiscal management, sustainable policies, and a commitment to intergenerational equity.
