The UK government’s recent budget, with elevated tax increases, aims to reduce debt but faces significant execution risks amid rising borrowing, slow growth, and political pressures, prompting concern from rating agencies about fiscal sustainability.
The recent UK budget, marked by significant tax increases, highlights the government’s strong commitment to reducing national debt, though the path ahead remains fraught with risks, according to Moody’s. The rating agency reaffirmed the UK’s Aa3 investment grade status with a stable outlook just last week, underscoring the importance of fiscal consolidation in its decision. However, Moody’s cautions that while the government’s determination to align public finances with its targets is encouraging, execution risks are substantial. Historical trends show a recurring pattern of government expenditure surpassing forecasts, leading to a build-up of deficits and debt.
This theme of fiscal vulnerability is echoed by S&P Global Ratings, which maintains the UK’s sovereign credit rating at ‘AA’ but points to ongoing fiscal risks despite the latest tax increases announced by Finance Minister Rachel Reeves. S&P highlights the possibility that political pressures ahead of the anticipated general election in 2029 may lead to a rollback of some austerity measures. The agency also notes the absence of significant growth-stimulating policies in the budget, though it acknowledges steady progress in narrowing the budget deficit. The UK’s strong income levels, diverse economy, and institutional independence remain pillars supporting its credit standing.
Adding to the fiscal challenges, the Office for Budget Responsibility (OBR) is reportedly preparing to downgrade economic growth projections for 2026 and the remainder of the parliamentary term. This downward revision, as reported by Sky News ahead of the budget announcement, is expected to reveal a £20-30 billion shortfall in public finances. The lower growth outlook, compounded by rising debt servicing costs, intensifies the fiscal tightening measures proposed by Reeves, including substantial tax hikes aimed at plugging the gap.
Moody’s earlier forecast stressed these tax increases would fall between £20 billion to £30 billion to align with the government’s fiscal rules, which commit to eliminating borrowing for day-to-day government spending by 2029-30. However, new data highlights significant borrowing challenges: public borrowing for the first half of the 2025-26 fiscal year reached £117 billion, £10 billion more than was anticipated in March, marking the highest non-pandemic nominal borrowing since 2020. This overshoot is attributed to rising spending and higher-than-expected debt servicing costs, with tax revenues failing to keep pace despite increased social security contributions.
Fitch Ratings further emphasises that the UK’s adherence to its fiscal rules is critical for maintaining its AA- credit rating. While the agency remains stable in its outlook, it flags that the UK’s projected fiscal deficits, which stand at around 5.3% of GDP in 2025 and are forecast to decline only moderately, remain high relative to peers where deficits typically hover near 2%. The UK’s debt-to-GDP ratio is also notably elevated, projected at about 106%, far exceeding the median for similarly rated nations. Fitch’s concerns were amplified by market nervousness following reports that Finance Minister Reeves might abandon planned income tax increases to avoid political backlash, underlining the delicate balance between fiscal discipline and political realities.
The borrowing figures released by the Office for National Statistics further underscore the scale of the challenge. Between April and October 2025, government borrowing hit £116.8 billion, surpassing earlier forecasts by nearly £10 billion and representing a record level outside the exceptional circumstances of the COVID-19 pandemic. October alone saw borrowing of £17.4 billion, far exceeding expectations. Analysts point to continued rises in public spending and debt interest costs as key drivers, compounded by tax receipts lagging behind needs. Consumer spending data signaled potential impacts of fiscal tightening, with a notable dip in October as the public braces for further tax pressures.
Finance Minister Rachel Reeves is under growing pressure to maintain fiscal discipline while navigating political considerations ahead of the next general election. Although her aims to end day-to-day borrowing by the decade’s end demonstrate a clear strategy toward debt reduction, the combination of slower economic growth, high borrowing costs, and political constraints paint a challenging picture for the successful implementation of these goals.
In summary, while the UK government’s latest budget reinforces its commitment to fiscal consolidation and debt reduction, rating agencies and analysts remain cautious. Execution risks are high amid an environment of economic slowdown, rising debt servicing payments, and political uncertainties. The coming years will test the government’s ability to balance fiscal responsibility with economic growth ambitions and social priorities, with significant implications for the UK’s creditworthiness and economic outlook.

This fiscal consolidation effort was a key factor in the agency’s earlier decision to reaffirm the UK’s Aa3 investment grade rating with a stable outlook. However, Moody’s cautioned that there are considerable execution risks associated with achieving these fiscal targets. The agency noted a pattern in recent years where government spending has consistently exceeded projections, leading to higher-than-expected deficits and public debt. Despite the positive intent, the success of the government’s debt-reduction goals remains uncertain.
- https://www.reuters.com/world/uk/uk-fiscal-position-remains-vulnerable-after-tax-raising-budget-sp-says-2025-11-28/ – S&P Global Ratings stated that the United Kingdom’s fiscal position remains vulnerable despite recent tax increases introduced by Finance Minister Rachel Reeves in the latest budget. Although the country retains a stable ‘AA’ sovereign credit rating—one level below the top ‘AAA’ grade—S&P highlighted fiscal vulnerability as a key factor limiting further upgrades. The agency warned of the potential for the government to reverse some budgetary tightening measures ahead of the upcoming general election, which is expected by mid-2029. While S&P acknowledged the budget contained few measures to stimulate economic growth, it did anticipate a continued narrowing of the UK’s budget deficit. The agency affirmed that strong income levels, a large and diverse economy, and institutional independence are factors sustaining the country’s credit standing.
- https://www.reuters.com/world/uk/uks-fiscal-watchdog-will-downgrade-growth-forecasts-sky-news-says-2025-11-24/ – According to a report by Sky News, the UK’s Office for Budget Responsibility (OBR) is set to downgrade its economic growth forecasts for 2026 and the remainder of the current parliamentary term. This revision will be revealed alongside Finance Minister Rachel Reeves’ budget announcement on Wednesday. The downgrade, coupled with higher debt servicing costs and other contributing factors, is expected to cause a £20-30 billion ($26.2-39.3 billion) shortfall in the public finances. As a result, Reeves is anticipated to propose tax increases to address the fiscal gap. The OBR’s growth and productivity projections are pivotal in shaping the government’s budgetary decisions. The UK Treasury has not yet commented on the Sky News report.
- https://www.reuters.com/business/moodys-affirms-uks-aa3-rating-ahead-budget-2025-11-21/ – Moody’s has affirmed the United Kingdom’s credit rating at Aa3 with a stable outlook, ahead of the country’s 2026 budget announcement scheduled for November 26. The decision reflects the UK’s robust economic fundamentals as the world’s sixth-largest economy and the government’s ongoing commitment to reducing its substantial budget deficit. Moody’s expects fiscal policies in the upcoming budget to align with the government’s defined fiscal rules, helping to manage debt costs. Finance Minister Rachel Reeves, preparing her second annual budget, is anticipated to introduce tax increases ranging between £20 billion and £30 billion to stay on course with fiscal targets. Reeves aims to eliminate borrowing for daily operational spending by 2029-30, though borrowing for long-term investments will continue. However, new data indicates a challenge: public borrowing during the first half of the 2025-26 fiscal year reached £117 billion—£10 billion more than forecast in March—marking the highest nominal borrowing since the COVID-19 pandemic in 2020.
- https://www.reuters.com/world/uk/uks-commitment-fiscal-rules-crucial-credit-rating-fitch-says-2025-11-14/ – Fitch Ratings emphasised that the UK government’s adherence to its fiscal rules, especially the goal of balancing the budget by 2029/30, is crucial for maintaining its AA- credit rating. Concerns were raised after reports that Finance Minister Rachel Reeves might abandon planned income tax increases to minimise political backlash, which rattled UK bond markets. Federico Barriga-Salazar of Fitch stated that while economic growth is relevant, the commitment to fiscal discipline plays a central role in rating assessments. Despite anticipated political debates over budget shortfalls, Fitch maintains its baseline assumptions and affirmed a ‘stable’ outlook in August. However, the UK’s projected fiscal metrics—deficits of 5.3% of GDP in 2025, falling to 4.4% by 2027, along with a debt-to-GDP ratio forecast of 106%—significantly exceed the median for similarly rated countries, where deficits are closer to 2% and debt-to-GDP around 52%. Nonetheless, Fitch currently sees less fiscal risk in the UK than in some peers, including France.
- https://www.reuters.com/world/uk/uk-borrows-higher-than-expected-174-billion-pounds-october-ons-says-2025-11-21/ – Between April and October 2025, the UK government borrowed £116.8 billion—the highest level on record for that period, excluding the COVID-19 pandemic years. This figure surpasses earlier projections by nearly £10 billion, highlighting a significant fiscal challenge for Finance Minister Rachel Reeves ahead of her upcoming budget announcement. October alone saw borrowing reach £17.4 billion, significantly higher than both official and economist forecasts. The scale of borrowing is fuelled by rising public spending and high debt servicing costs, while tax revenues—despite recent increases in social security contributions—have not kept pace. The current budget deficit stands at nearly £84 billion for the financial year so far, marking a 10% rise from the previous year. Economic analysts, including those at the Institute for Fiscal Studies, point to uncertain tax income and sustained debt costs as ongoing obstacles. Reeves aims to cease borrowing for daily expenses by decade’s end, and her deputy emphasises plans for fiscal tightening, aiming to reduce the primary budget deficit significantly among G20 nations. However, concerns over likely tax hikes are already affecting consumer spending, which declined notably in October.
