Scope Ratings Warns U.S. Debt to Hit 160% of GDP by 2036, Highlighting Fiscal Fragility

Key points

• Scope Ratings projects U.S. government debt will climb to approximately 160% of gross domestic product within the next ten years.
• The agency maintains the U.S. credit rating at AA- with a stable outlook, noting that current fiscal paths are unsustainable without significant economic growth or spending cuts.
• Scope expects net interest costs to reach 'exceptionally high' levels by 2031, increasing the government's sensitivity to shifts in investor sentiment.
• The U.S. currently holds a credit rating three levels below the highest possible grade from Scope, which is two levels below the ratings assigned by Moody’s, Fitch, and S&P.
• Scope flags risks associated with the upcoming congressional debate over the U.S. debt ceiling, warning that continued borrowing could exacerbate fiscal pressures.

Background

Recent months have seen significant volatility in the U.S. bond market, with the 10-year Treasury yield briefly crossing 5% in September 2026. Analysts have cited a combination of sticky inflation, geopolitical tensions, and a national debt exceeding $40 trillion as drivers of these yield spikes. Previous coverage highlighted that Treasury buybacks and policy adjustments have provided only temporary relief, leaving markets on edge as the debt burden continues to grow.

How outlets are covering it

Investing.com reports that Scope Ratings is the only European-based agency among the five used by the European Central Bank, and its assessment is notably more cautious than its larger competitors. While Fitch’s chief sovereign analyst suggested in January that another U.S. downgrade would be highly unusual, Scope’s current rating is two levels below those of Moody’s, Fitch, and S&P. The Northeast Mississippi Daily Journal, through its columnist section, reflects broader public anxiety, describing the situation as a potential 'debt spiral' that threatens financial stability and highlights the political divide in addressing fiscal issues. In contrast, Scope focuses on structural economic metrics, such as the ratio of debt to GDP and interest costs, rather than political rhetoric.

Why it matters

The warning from Scope Ratings underscores the growing fragility of U.S. fiscal policy. As debt reaches 160% of GDP, rising interest costs could crowd out other government spending, potentially impacting social programs and infrastructure. For the middle class, higher borrowing costs for mortgages and credit cards, driven by elevated bond yields, could reduce disposable income and increase the cost of living. The divergence in credit ratings also signals a lack of consensus among global financial institutions, which may affect investor confidence and the cost of capital for the U.S. economy.

What to watch

Investors and policymakers will closely monitor the upcoming congressional debate over the U.S. debt ceiling, as Scope warns that a failure to reach an agreement could trigger a credit downgrade. The market will also watch for signs of fiscal adjustment, such as spending cuts or revenue increases, which could mitigate the projected rise in debt-to-GDP ratios. Additionally, the Federal Reserve’s monetary policy decisions will be crucial in managing inflation and interest rates, which directly impact the cost of servicing the national debt.
