Debt levels will likely exceed historical norms, even under optimistic economic forecasts. Productivity growth, measured by output per unit of input, has a major impact on the relationship between government debt and GDP. Productivity growth exceeds expectations, resulting in higher GDP and simpler debt management. Forecasting productivity growth is challenging, with experts sometimes missing significant swings in patterns. The late 1990s saw a significant increase in trend productivity growth. Between 1995 and 2004, multifactor productivity grew at a rate of 2% per year, following two decades of stagnation. Although the spike is attributed to advancements in information technology, the economic benefits of better computers were not fully understood for a long time.

Robert Solow  a Nobel Prize-winning economist once said You can see 

The computer age everywhere except in productivity statistics." Productivity growth stopped abruptly in the early 2000s, and has averaged barely 0.9 percent annually since 2005. The CBO assessed the debt-to-GDP ratio in its long-term budget projection for sensitivity to productivity growth changes (CBO 2023d). According to CBO's baseline projections, multifactor production is expected to expand at a pace of 1.1%, slightly faster than the average throughout the first two decades of the 2000s. The CBO recalculated the debt-to-GDP ratio based on two scenarios: optimistic (0.5 percentage points greater trend growth) and pessimistic (0.5 percentage points lower). The results are shown in figure 8 as blue bars. The anticipated debt-to-GDP ratio differs from the baseline (in red) in both optimistic and pessimistic scenarios, but gradually increases over time. In the optimistic scenario, the debt-to-GDP ratio is 44 percentage points lower in the early 2050s than in the baseline, whereas in the pessimistic scenario, it is 47 percentage points higher. The margin between optimistic and pessimistic forecasts is nearly equal to the present debt-to-GDP ratio, indicating uncertainty in budget estimates. Debt is projected to reach 137 percent of GDP in 2053, exceeding historical levels and likely to continue to rise beyond the forecast frame.Given the unexpected changes in interest rates, it's important to evaluate how projected federal debt relative to GDP is affected by the predicted interest rate path for government borrowing.

The decline in Treasury yields over the past few decades has improved fiscal

Outcomes (for given levels of revenue and noninterest spending), and the reduction in projected yields has improved the fiscal outlook. BFigure 8 depicts the results using gray bars. The expected debt-to-GDP ratio is minor compared to the baseline (in red) in 10 years, but increases significantly over time. In the optimistic scenario, the debt-to-GDP ratio is 38 percentage points lower in the early 2050s compared to the baseline, whereas in the pessimistic scenario, it is 50 percentage points higher. Even in the most optimistic scenario, the debt-to-GDP ratio will exceed historical levels by the end of the projection window and likely continue to rise. Sensitivity analysis show that "good luck" with macroeconomic outcomes is unlikely to alter the conclusion that US government debt is unsustainable. Under existing law, less-than-expected macroeconomic results, as well as positive scenarios, are equally likely to increase federal debt to unprecedented proportions. According to Summers (2023), certain policy changes may face political opposition, such as the expiration of 2017 tax cuts and a decrease in defense and nondefense discretionary spending relative to GDP to levels not seen in the past 50 years.New issues may prompt Congress and the president to boost spending or lower taxes for specific goals, posing an additional risk to the federal debt's trajectory.Predicting long-term interest rates is tough. In its July 2023 long-term budget outlook, the CBO projected a nominal yield of 3¾ percent on ten-year Treasury notes in 10 years, rising to roughly 4½ percent over the next two decades (CBO 2023c). 

As consumer price index inflation returns to the Federal Reserve's

Percent target for personal consumption expenditures (PCE), the real yield on ten-year Treasuries is expected to rise from 1½ percent to 2¼ percent by the early 2050s. This is due to rising federal debt, which will increase the cost of borrowing. In comparison, the real yield averaged 3¾ percent from 1988 to 1997, 2¼ percent from 1998 to 2007, and ¾ percent between 2008 and 2019.The CBO analyzed the sensitivity of budget predictions to the projected interest rate path (CBO 2023d). The CBO estimated the debt-to-GDP ratio under two scenarios: an optimistic scenario where the average interest rate on federal debt is below the baseline rate by 5 basis points starting in 2023 and increasing by 5 basis points each year (before macroeconomic effects are accounted for), and a pessimistic scenario where the interest rate on federal debt is higher by corresponding amounts. The International Monetary Fund (IMF) and notable economists (e.g., Blanchard 2023) agree that interest rates will remain historically low. Rogoff, Rossi, and Schmelzing (2022) suggest that interest rates may return to previous levels, while Summers (2023) cites rising global government debt as a reason for higher interest rates. Although the recent jump in the ten-year Treasury rate in early 2023 may support a negative outlook, it is too early to draw definite judgments.
