Britain's finance minister John Healey delivered his first budget in London on Wednesday, telling Parliament that the government will have a smaller fiscal buffer of £15 billion in the 2029/30 financial year, citing forecasts from the Office for Budget Responsibility (OBR).

Yaani, in simple words: £15 billion (about $20 billion) is the amount by which the government's tax revenues are expected to be higher than its day-to-day spending in 2029/30 — a safety cushion, not cash in a vault. Healey said the buffer is expected to rise to £22 billion in 2030/31.

The cushion has shrunk. At the time of former finance minister Rachel Reeves' budget update in March, the OBR estimated the government had £24 billion of so-called fiscal headroom. A Reuters poll of bond dealers earlier this month also pointed to £15 billion of headroom, as higher borrowing costs weighed on the government's spending plans.

Borrowing to fall, deficit to end in three years — Healey

"That's what a buffer is for. Use it when you need it. Rebuild it when you can," Healey said. "So, despite the global challenges, this Budget puts us on track to eliminate the current budget deficit and get Britain's finances into the black within 3 years." In the OBR forecast he cited, borrowing falls to 4.2% this year, 3.4% next year, 2.9% in 2028/29, 2.1% in 2029/30, and 1.8% in 2030/31 and 2031/32.

Healey said he had chosen to use some of the headroom established last year to absorb the impact of the Iran war and to protect the economy and family budgets. "The OBR sets out that the war in the Middle East is a key driver affecting today's forecasts. And this government continues to work with our allies to end the conflict and restore shipping through the Strait of Hormuz," he said.

Opening his speech, Healey called it "a budget for the working people of Britain, for British businesses, big and small, delivered at a time when global uncertainties and pressures are swirling worldwide", built, he said, on fiscal discipline. It is the first budget since Andy Burnham became prime minister in July, replacing Keir Starmer.

Why the room to manoeuvre was so tight

Ahead of the speech, AFP reported that Healey was juggling commitments to defence spending and easing household bills with little financial room to manoeuvre, as rising inflation and borrowing costs — largely a consequence of the US-Iran war — increased the government's debt pile. Labour had ruled out rises to income tax and capital gains tax, raising the prospect of spending cuts to balance the books, according to analysts cited by AFP.

A Reuters factbox published before the budget said the main measures expected included a plan to fully fund the government's defence commitments alongside a pathway to the 2035 NATO spending pledge, a levy on banks to fund a targeted package of household support — with The Guardian reporting energy subsidies worth more than £1 billion (yaani, more than $1.3 billion), mostly for lower-income households — and fiscal devolution giving regional leaders in England a share of locally generated tax.

For Punjabi and Indian families in Britain, the numbers that matter most are the ones Healey put at the centre of the speech: whether the smaller buffer holds if energy and borrowing costs rise again, and whether the promised path back into the black within three years survives the next global shock.
