UK Economy: Spring Statement Confirms Tighter Fiscal Path Than Autumn Budget

Chancellor Rachel Reeves presented a Spring Statement to Parliament that acknowledged the significant change in the UK’s fiscal outlook since the October 2025 budget, revising growth projections downward in line with the OECD and Office for Budget Responsibility assessments and adjusting the spending trajectory to reflect a slower improvement in the public finances than had been projected in the autumn. The statement confirmed that the Iran war and its inflationary consequences had materially altered the economic context within which the government was managing public finances.

The revised growth forecast, centred on the OECD’s 0.7 percent estimate for 2026, implied lower tax receipts and higher benefit spending than had been built into the October projections, creating a gap in the fiscal position that the Chancellor addressed through a combination of modest spending profile adjustments and revised debt management assumptions. Some capital investment commitments were confirmed as proceeding on schedule while certain non-priority current spending lines were subject to more modest growth than had been previously indicated.

The Office for Budget Responsibility confirmed that the government remained on course to meet its self-imposed fiscal rules — requiring debt to be falling as a proportion of GDP and requiring that day-to-day spending be met from tax revenues rather than borrowing — but that the headroom against those rules had been reduced by the external shock. OBR chair Richard Hughes noted in his published assessment that the headroom was thinner than was comfortable and that a sustained period of higher energy prices could push the government into a position where meeting its rules required additional fiscal action.

Opposition parties questioned whether the fiscal rules themselves were constraining necessary investment and whether the government’s approach to managing the Iran war’s economic consequences was sufficiently ambitious in its support for affected households and businesses. The government maintained that its rules provided a credible anchor for market confidence and that departing from them would impose higher borrowing costs that would ultimately harm the public finances more than any short-term stimulus benefit.
