Overview
- The Institute for Fiscal Studies warned on Monday that Chancellor John Healey faces about a £35 billion gap by 2030–31 driven by higher inflation eroding departmental budgets and the cost of reaching a 3% of GDP defence target.
- The IFS estimates meeting the defence goal will add roughly £11 billion in 2030–31 and that filling the full shortfall would require either large tax rises, benefit cuts, or sizeable reductions in other departmental spending.
- Several high‑profile options appear ruled out after lobbying and Cabinet concern, with ministers reportedly dropping plans to widen the mansion surcharge and a proposed warehouse levy while keeping bank windfall taxes, capital gains tax reform and pension changes under active consideration.
- Markets and officials are watching the Office for Budget Responsibility update closely because rising gilt yields and lower headroom estimates tighten the room for manoeuvre and make borrowing‑heavy fixes politically and financially risky.
- The shortfall has direct impacts for people and services: without extra revenue some public services face real‑terms cuts, pension tax changes could hit savers and pensioners, and the government may target wealthier homeowners and financial firms to protect low‑income households.
