Higher Interest Rates and the Mounting Concerns Surrounding the US Deficit: A Complex Challenge Ahead


The United States economy is facing a new challenge as interest rates continue to rise. This surge in interest rates has sparked a growing chorus of concerns about the country’s mounting deficit. The U.S. government’s persistent budget deficit and increasing debts were not high on Wall Street’s list of worries when interest rates were at rock bottom for years. However, with the recent spike in borrowing costs, many investors and economists are expressing fears that the United States’ large debt pile may become less sustainable.

The Impact of Rising Interest Rates

Federal Reserve officials have been aggressively raising interest rates to control inflation, which has reached about 5.3 percent since early 2022. These officials have predicted that interest rates could remain high for years to come, challenging the expectations of investors who had bet on rates falling significantly in the near future. As a result, long-term interest rates have soared in financial markets, with the rate on 10-year Treasury bonds reaching a nearly two-decade high.

The rise in Treasury rates affects various aspects of the economy as it drives many other borrowing costs, including mortgages and corporate debt. The factors behind this surge in rates are complex and multifaceted, with strong growth, reduced foreign demand for U.S. debt, and concerns about debt sustainability all playing a role.

The Growing Debt Pile

The United States’ gross national debt currently stands at just above $33 trillion, exceeding the total annual output of the American economy. The debt is projected to continue growing both in dollar figures and as a share of the economy. While the climbing cost of holding such a significant amount of debt is fueling discussions among economists and investors about the appropriate size of the government’s annual borrowing, there is no consensus in Washington for deficit reduction through higher taxes or significant spending cuts.

The Changing Perception on Deficits

The renewed concern about the U.S. deficit represents a stark reversal from previous years when many mainstream economists believed that the country’s debt was manageable. Low interest rates had led to the belief that the government could borrow cheap money to fund relief in times of economic trouble and investments in the future. However, the recent surge in interest rates has prompted a shift in the perception of deficits.

According to Jason Furman, an economist at Harvard and former economic official under the Obama administration, the view on deficits is closely tied to interest rates. Furman previously estimated that the growing cost of interest on federal debt would remain sustainable for some time, considering inflation and economic growth. However, with the significant increase in rates, the calculus has changed.

Factors Contributing to the Deficit

The United States has been running an annual budget deficit since 2000, making up the gap by borrowing money. Recent years have seen rising deficits due to tax cuts, spending increases, and emergency economic assistance approved by both Democratic and Republican presidents. Additionally, the aging population has driven up the costs of Social Security and Medicare without corresponding increases in federal tax rates. This year, even with a growing economy, the deficit as a share of the economy increased under President Biden, similar to the trend observed during the pre-pandemic years under President Donald J. Trump.

The Impact of Higher Interest Rates on the Deficit

Higher interest rates, along with weak tax collections, are expected to contribute to a doubling of the federal budget deficit over the last year, according to projections from the Congressional Budget Office. The deficit, properly measured, grew from $1 trillion in the 2022 fiscal year to an estimated $2 trillion in the 2023 fiscal year. If borrowing costs continue to climb or remain high for an extended period, the government will accumulate debt at a much faster rate than previously expected.

The Surging Bond Yields

A recent surge in longer-term bond yields is attributed to several factors. While the Federal Reserve has been raising short-term interest rates for about 18 months, rates on longer-term bonds remained relatively stable during the first half of this year. However, investors have gradually begun to consider the possibility that the Fed will keep interest rates higher for a longer period, given the solid economic growth even in the face of elevated borrowing costs. Additionally, the reduced demand for government bonds from the Federal Reserve, as it shrinks its balance sheet, and key foreign governments also pulling back from bond purchases have contributed to the increase in bond yields.

Debt Sustainability Concerns

Some analysts suggest that the rise in bond yields is also tied to concerns about debt sustainability. To meet higher interest costs, the government may need to issue even more debt, exacerbating the problem and drawing attention to the already mammoth debt pile. This concern is compounded by the fact that the United States is borrowing heavily at a time when the economy is strong and the unemployment rate is low, suggesting that the government’s assistance may not be necessary.

Implications and Future Considerations

The rising interest rates and growing deficit have raised questions about the appropriate course of action. The White House is cautious about making immediate changes but acknowledges the need to monitor the situation closely. Treasury debt sales have increased significantly, and if rates continue to climb, the government will face even greater challenges in managing its debt. Economists and policymakers are divided on the best path forward, with differing opinions on deficit reduction measures such as tax increases or spending cuts.


As interest rates continue to rise, concerns about the U.S. deficit are growing. The government’s persistent budget deficit and increasing debts have become a cause for worry, particularly as borrowing costs surge. With the United States’ gross national debt exceeding $33 trillion and projected to continue growing, economists and investors are engaging in discussions about the sustainability of this debt. The impact of higher interest rates, along with weak tax collections, is expected to contribute to a significant increase in the federal budget deficit. As the country faces these challenges, policymakers and economists must carefully consider the appropriate measures to manage the deficit and ensure the long-term stability of the economy.
