US Debt Reaches $40 Trillion with 100% Publicly Held Debt-to-GDP Ratio

The United States' debt burden is a pressing concern for lawmakers, and the Congressional Budget Office's (CBO) latest forecast paints a bleak picture. The country's gross debt has ballooned to $40 trillion, with publicly held debt accounting for an astonishing 100% of GDP.

Maintaining this ratio, let alone reducing it, would require a remarkable economic boom that shows no signs of materializing anytime soon. According to the CBO's projections, the debt-to-GDP ratio is set to soar to 120% by 2036, a stark reminder of the need for urgent fiscal action.

However, even with stronger economic growth, which could bring in additional revenue for the federal government, it may not be enough to steady the ship. The CBO's Director Phillip Swagel pointed out that while a robust economy can boost wages and lift Social Security benefits, it also tends to drive up interest rates, increasing debt servicing costs.

This delicate balance highlights the limitations of relying solely on economic growth to address the country's fiscal challenges. As Swagel noted during a recent Minneapolis Fed conference, even with faster GDP expansion, sustaining a healthy economy is no guarantee that the nation's debt will come under control.

The Congressional Budget Office's next set of economic forecasts will take into account its views on artificial intelligence, which are expected to contribute to faster growth in the future.

However, even with this additional boost, the budget deficit is so significant that it cannot be overcome by AI-powered growth alone, according to Swagel. He warned that more drastic measures would be needed to stabilize the debt.

Kashkari then asked how much higher growth rates would need to be to bring down the debt burden. Swagel provided some rough estimates based on interest rate assumptions of 4%-5%. His calculations suggested that nominal GDP growth would have to reach 7%-8%.

Meanwhile, real GDP growth would need to hit a pace of 5%-6% for the nation's debt to be brought under control. These projections are significantly higher than current growth rates, which have been sluggish in recent quarters.

The US Treasury's ability to absorb debt through bond sales is currently being met with surprisingly high demand from investors.

However, long-term yields have skyrocketed to their highest levels in 24 years, a trend that could be exacerbated by an economic downturn or sudden interest rate hikes.

This surge in yields can be attributed to several factors, including the strong economy, rising expectations for Fed rate increases, and persistently high oil prices driving inflation.

The sheer scale of US debt is also contributing to this upward trend, with even modest increases in the debt ratio leading to significant hikes in long-term interest rates.
