John Healey's First Budget: Who Wins and Who Pays 2026

John Healey’s first budget, to be delivered on Wednesday, will set the tone for Andy Burnham’s premiership and reveal who wins and who pays in the new government’s economic plan. Despite promises of no leaks, much of what Healey will announce has already been signalled by official and unofficial sources. Here is what to expect.

The Fiscal Headroom: How Much Money Is There?

Healey will allocate about £1.42tn this year on day-to-day spending and public investment. About £100bn of this will go on debt interest after a rise in the interest rate the government pays to multidecade highs.

Most of this increase can be blamed on the Gulf conflict launched by the US and Israel at the end of February, which has taken the oil price to above $110 a barrel and the price of gas to levels not seen since late 2022. Government borrowing in this financial year has fallen compared with 2025-26, but not by as much as the Office for Budget Responsibility estimated in March, mainly owing to higher debt financing.

Healey is spending about £1bn a month more than forecast. Those costs mean the buffer of £24bn built up in the last tax-raising budget is likely to have halved to £12bn, according to the Resolution Foundation thinktank. The Treasury would be more comfortable having this headroom at about £15bn, according to economists at ING.

Who Wins: Defence and AI

Healey’s background as a former defence secretary suggests that defence spending will be a major winner. The government has already pledged major AI investment for UK security, and defence shares have surged since Healey’s appointment. Expect further commitments to modernise the armed forces and boost cyber capabilities.

AI and technology sectors are also likely to benefit from increased investment, as the government seeks to position the UK as a leader in emerging technologies. This could mean more funding for research and development, as well as tax incentives for tech companies.

Who Pays: Taxpayers and Borrowers

With the fiscal buffer halved, Healey may need to find savings or raise taxes to meet his fiscal rules. The chancellor has promised no return to austerity, but pressure on public services remains. Possible revenue-raising measures include changes to capital gains tax, inheritance tax, or pension reliefs.

Borrowers could also feel the pinch if the government’s borrowing costs remain high. Mortgage rates are already elevated, and further increases in gilt yields could push them higher. Savers, however, might benefit from higher interest rates on savings accounts.

The Big Picture: What It Means for You

Healey’s budget will be a balancing act between supporting growth and maintaining fiscal credibility. The decisions he makes will affect household finances, business confidence, and the UK’s standing in global markets. Key areas to watch include:

• Defence and security: Increased spending may boost related stocks but could divert funds from other areas.
• Taxation: Changes to capital gains and inheritance tax could impact wealth planning.
• Public services: Funding settlements for the NHS and local government will determine service quality.
• Borrowing costs: Higher gilt yields could keep mortgage rates elevated.
• Business incentives: AI and tech investment may create opportunities for startups and investors.

What to Watch Next

The budget will be scrutinised for its growth forecasts and the OBR’s assessment. If growth is revised down, Healey may need to tighten further. The reaction of gilt markets will also be key: a sharp rise in yields would signal investor concern.

Healey’s commitment to AI is also expected to be a centrepiece. Our article on John Healey Budget Pledges Major AI Investment for UK Security details how this could reshape the tech landscape and national security.

Some economists argue that Healey should be bold on borrowing to stimulate growth. This view is explored in Healey Urged to Be Bold on Borrowing for Growth, which contrasts with the cautious approach favoured by the Treasury.
