Surging interest rates and election-related risks threaten the U.S. debt outlook, warns Scope Ratings.
The outlook for U.S. debt has become increasingly precarious, driven largely by rising interest costs and looming political risks. According to a recent report by Scope Ratings, surging Treasury yields pose a significant threat to the fiscal stability of the inflation-as-central-banks-meet-globally/">United States, amplifying the urgency for effective monetary and fiscal policies.
On a recent Friday, the Europe-based credit ratings agency maintained its sovereign rating for the U.S. at AA-, positioning the country three notches below the highest rating and two levels beneath the AA+ grades assigned by competing agencies such as Moody’s, Fitch, and S&P Global Ratings.
Notably, Scope acknowledged several strengths underpinning the U.S. economy: a resilient economic landscape, the dollar's status as the world's reserve currency, robust institutions like the Federal Reserve, and the unmatched scale and liquidity of U.S. capital markets.
However, despite the stable credit outlook, Scope highlighted worsening fiscal deficits stemming from persistent "structural expenditure pressures" coupled with a lack of political resolve for necessary fiscal reforms. This raises concerns over the sustainability of U.S. debt over the medium-term.
A critical factor contributing to the deteriorating fiscal situation is the escalating cost of servicing debt. Scope forecasts that, despite U.S. primary deficits—deficits excluding interest payments—remaining steady at approximately 3.5% of GDP, the growing interest payments will exacerbate overall fiscal deterioration.
As of now, the yield on 10-year Treasury bonds stands at 5.27%, significantly exceeding the long-term estimates by the Congressional Budget Office, which projected yields at 4.3% from 2028 to 2031 and 4.4% from 2032 to 2036. Analysts at the Committee for a Responsible Federal Budget (CRFB) estimate that if Treasury yields remain about 1 percentage point above previous projections, an additional $3.5 trillion will be added to the national debt over the next decade.
Scope issued a warning regarding these rising interest costs, noting that they severely limit the government's ability to respond to unexpected economic shocks. Without substantial reforms or stronger economic growth, the burden of general government debt could approach a staggering 160% of GDP by 2036. This revelation underscores the urgency of addressing the unsustainable fiscal trajectory identified by Scope.
The U.S. government's strategy to issue debt has also undergone significant changes, with a noticeable shift towards short-term maturities as opposed to long-term bonds carrying higher rates. This decision, propelled by Treasury Secretary Scott Bessent and initially set in motion by the Biden administration, includes plans for buybacks that aim to exchange longer-term debt for more short-term notes.
This recalibration has economic implications, as a growing proportion of U.S. debt is now coming due on tighter timelines. Consequently, rolling over this debt could become costlier, particularly in an environment of rising interest rates, as experienced over the past several months.
Another complicating factor is the increasing role of price-sensitive hedge funds within the $32 trillion Treasury market. These entities have emerged as more prominent players, replacing traditional foreign central banks that historically acted as stable holders of U.S. debt, subsequently contributing to market volatility.
The interplay between hedge funds and Treasury yields may introduce new sources of instability into the debt markets, further exacerbating the risks associated with short-term debt rollovers, as these fluctuations can lead to unpredictable costs for the government.
As if the rising interest costs and market shifts weren't enough, the ever-present issue of the U.S. debt ceiling looms large. Scope forecasts that the current debt limit of $41.1 trillion will likely be reached by early 2027. Although the Treasury Department can resort to "extraordinary measures" to delay any potential default for a limited period, the necessity of political action remains as legislators must eventually address the issue.
Scope's baseline assumption suggests that policymakers will ultimately reach an agreement to raise or suspend the debt limit. However, the political landscape following the midterm elections may heighten the potential for extended partisan stalemates. Repeated episodes of brinkmanship over the debt ceiling not only expose underlying weaknesses in fiscal governance but also contribute to cyclical volatility within markets.
A recent report from CRFB coincided with the fiscal year-end tally, revealing that fiscal 2026 concluded with a staggering budget deficit of $2 trillion, representing 6.2% of GDP. Public debt reached $32.3 trillion, equivalent to 100% of GDP, and debt-interest costs soared to a record high of $1.1 trillion—accounting for 3.4% of GDP and marking the second-largest budget item after defense and Medicare.
CRFB’s analysis indicates that, based on trends observed over the past year, interest payments are likely to increase, alongside lower tariff revenues, potentially driving deficits and debt well beyond the CBO's existing projections. Overall, the U.S. faces a challenging fiscal scenario that demands urgent attention from policymakers to avert a fiscal crisis.
The current trajectory outlined by Scope Ratings highlights a growing risk for U.S. debt sustainability as rising interest costs and a charged political landscape combine to curtail fiscal governance and responsiveness. With each rise in service costs, the government’s margin for error narrows, leaving it vulnerable to economic fluctuations and market sentiment.
Strategic fiscal reforms, alongside an emphasis on stable long-term yield projections, are crucial for bolstering confidence in U.S. sovereign credit. Ensuring that the capital markets remain supportive of U.S. debt will be paramount in the coming years as fiscal realities intersect with political dynamics.
As stakeholders navigate this complex environment, an ongoing dialogue around economic growth, fiscal discipline, and sound governance will be essential to safeguard the nation’s financial future and the credibility of its debt instruments.
