Healey's first Budget leaves £15bn of fiscal headroom

Budget leaves thinner cushion

Chancellor John Healey delivered his first Budget on 28 October 2026. The Office for Budget Responsibility estimated fiscal headroom at £15bn for 2029-30, below the £24bn forecast in March, Healey said. Headroom is the amount the government can increase spending or lower taxes without breaking its own fiscal rules. It is projected to rise to £22bn in 2030-31.

The budget was in line with the cautious approach investors had anticipated. Ten-year gilt yields fell 2.1 basis points to 5.321%, according to Tradeweb. Sterling was 0.1% lower at $1.3291 against the dollar and dropped 0.2% versus the euro to 0.8374 per euro, little changed from levels before the budget.

Gilt market reaction

The 30-year gilt yield fell about 4.5 basis points to around 5.70%, Reuters and Dow Jones reports said. The 10-year gilt yield fell to a five-week low on 29 October, CurrencyNews reported. Sterling rose 0.4% to $1.3429 on 30 October, the best-performing major currency that day, Reuters reported. The pound was heading for a gain of about 1% in October, its first monthly rise since August, though it was still down around 0.6% for the year.

The relief followed a tense period. The 30-year gilt yield broke above 6% on 1 October and peaked at about 6.03% on 7 October, its highest level since 1998, Admiral Markets reported. The 10-year yield hit a 19-year high of 5.527% in early October, according to LSEG data. Sterling touched its 2026 low of $1.3137 on 14 October.

Fiscal rules and pre-Budget estimates

Healey repeated his commitment to the fiscal rules and to the Labour manifesto pledge not to raise income tax. The rules require debt as a share of GDP to fall by 2029-30, and day-to-day spending to be in balance so the government is not continually borrowing to pay for everyday operations.

Before the Budget, Pantheon Macroeconomics estimated headroom had already fallen to roughly £13bn from £23.6bn at the Spring Statement, as a global bond sell-off pushed yields up. That was a pre-Budget estimate. The OBR's post-Budget figure was £15bn for 2029-30, below its March forecast of £24bn. Pantheon put the annual consolidation needed to restore March's headroom at £11bn.

Why gilts matter for mortgages and borrowing

The 10-year gilt is a benchmark for mortgage pricing and government borrowing costs, CurrencyNews reported. Fixed-rate mortgages are priced from swap rates that derive from expectations about where gilt yields are heading, not directly from the 10-year gilt. Lower gilt yields can, over time, feed through to slightly cheaper fixed-rate mortgages, although a likely Bank of England rate rise on 5 November may cancel out some of that benefit.

The OBR forecast an extra £14bn in interest payments on debt this year. The Debt Management Office said its net financing requirement would be £258.6bn in 2026-27, up £7.4bn from April's estimate of £251.2bn. It also cut planned issuance of long-dated gilts, which helped bring down 20-year and 30-year yields, Admiral Markets said.

Budget measures and analyst reaction

The Budget included household relief from energy bills and extra taxes on banks and gambling. It also created a tax-free savings account for first-time home buyers and lowered the threshold for business asset disposal relief in capital gains tax. The bank surcharge doubled to 6% for 15 months. UK bank shares rose on Budget day as the rise was seen as manageable.

Kathleen Brooks, research director at XTB, said "the bond market is calling it a very boring budget", Reuters reported. Lale Akoner, an analyst at eToro, said sterling and gilts' muted response suggested the budget broadly met expectations and reassured investors without materially changing Britain's outlook. Harry Woolman of Validus Risk Management said most main measures had been trailed in advance, given limited fiscal headroom and little political room for maneuver.

"From here, we believe that inflation and Bank of England expectations are likely to matter more for the pound and borrowing costs," Akoner said.

What happens next

The Bank of England was due to decide on interest rates on 5 November. Before the Budget, markets largely expected a November hike, but the Budget could change how many increases follow. The Bank held Bank Rate at 3.75% in September by six votes to three, with three policymakers preferring an immediate increase to 4%. UK inflation rose to 3.5%, with core inflation at 2.8% and services inflation at 3.7%. Higher inflation also lifts the government's debt-interest bill.
