UK Economic and Fiscal Outlook Points to Persistent Growth Challenges and Rising Energy and Interest Rate Pressures

The Office for Budget Responsibility (OBR) has published its Economic and Fiscal Outlook (EFO) for October 2026, detailing central forecasts and risks for the five years leading to 2031-32. Prepared by the Budget Responsibility Committee, the report incorporates data up to and including the October 2026 Budget and highlights ongoing economic challenges, including weak GDP growth, elevated government borrowing, and high debt levels relative to historical and international standards.

Economic Context and Shocks

According to the EFO, the UK economy continues to face adverse shocks following the 2008 global financial crisis, EU exit trade barriers, the pandemic, and recent energy price spikes. Since the March 2026 forecast, further pressures have emerged:

• Energy Prices: Higher oil and gas prices have created a negative terms-of-trade shock, pushing up inflation and reducing real household disposable incomes. Oil prices peaked around $95 a barrel in early 2026, while gas prices are projected to peak near 150 pence a therm.
• Interest Rates: Bank Rate and gilt yields have risen significantly. The central forecast projects Bank Rate reaching over 4¼ percent by mid-2027 and over 4½ percent by the end of the forecast period.
• Inflation and Growth: CPI inflation is forecast to peak at a quarterly high of 3¾ percent in early 2027 before returning to the 2 percent target by 2028 as energy prices decline. Real GDP growth is expected to slow from approximately 1¼ percent in 2026 to 1 percent in 2027.

Fiscal Projections and Mandates

Pre-measures borrowing is projected to average £11 billion per year higher than March estimates due to higher interest rates and inflation forecasts. Direct policy measures further adjust borrowing figures across upcoming fiscal years. Overall, public sector net debt is forecast to peak at approximately 97 percent of GDP in 2028-29 before slightly declining to 96 percent in 2031-32. The central forecast indicates that the current fiscal mandate for a surplus in 2029-30 is met by a margin of £15 billion, while the supplementary target for falling public sector net financial liabilities is met by £24 billion.
