UK Borrowing Falls as Reeves Delivers Post-Pandemic Fiscal Consolidation
Britain plans fastest deficit reduction in G7 as gilt issuance holds at £304 billion despite tighter fiscal stance.
The UK government borrowed £112 billion in the first ten months of fiscal 2025-26, £15 billion less than the same period last year, as Chancellor Rachel Reeves executes the most aggressive fiscal consolidation in the G7.
The decline marks a significant shift from pandemic-era spending, with government borrowing in the first 10 months of 2025/26 totaling £112 billion, tracking £8 billion below Office for Budget Responsibility forecasts. Public sector net borrowing as a share of GDP in 2025-26 is set to be the lowest for six years, with borrowing falling from 4.5% of GDP in 2025-26 to 1.9% in 2030-31.
Yet gross gilt issuance tells a different story. The DMO’s Net Financing Requirement for 2025-26 rose by £5.6 billion to £314.7 billion, with planned total gilt sales reaching £303.7 billion — hardly a reduction. The apparent contradiction reflects a critical feature of debt management: gross issuance includes refinancing £100+ billion in maturing debt annually, not just funding new borrowing.
Structural Shift in Debt Composition
The DMO dramatically shortened the maturity profile of new debt. Long-dated issuance fell to 13.4% of total issuance, down from 18% in the prior year — a response to persistently inverted yield curves that made 30-year borrowing prohibitively expensive relative to shorter maturities.
The share of short or ultra-short gilts issued has risen from 29% in the 10 years prior to the pandemic to 34% in the three years following, reducing refinancing costs but increasing exposure to interest rate volatility. More debt now rolls over annually, amplifying the impact of rate movements on fiscal sustainability.
UK annual inflation was 3.0% in January 2026, down from 3.4% in December 2025, driven by softer transport and food prices. The Bank of England expects the inflation rate to fall sharply to near its 2% target in April, providing space for further monetary easing that could support gilt demand.
Fastest G7 Consolidation Path
From 2025 to 2030, the UK is reducing government borrowing more than any other G7 country, according to government data. The primary deficit falls by 1.4 percentage points between 2025-26 and 2027-28, moving into surplus — the first primary surplus since 2001-02, with a 1.4% of GDP primary surplus by 2030-31 driven by higher tax revenue.
The consolidation is heavily backloaded. Policy measures in Budget 2025 increase borrowing in the near term through spending increases, then reduce borrowing in the medium term primarily through taxation, pushing a greater share of consolidation to 2028-29 and 2029-30. This timing raises election-cycle questions: will a government implement painful tax rises heading into 2029 polls?
Markets have begun pricing in credibility. UK 10-year gilt yields fell to 4.32% on February 25, 2026, and dropped further below 4.35% — the lowest level since December 2024 — as safe-haven flows and diminishing fiscal anxiety compressed spreads. 10-, 20- and 30-year borrowing costs have fallen by 20 basis points more than comparative countries since Rachel Reeves’ Labour party conference speech, suggesting the UK borrowing premium may be unwinding.
Vulnerabilities Persist
The UK’s fiscal position remains brittle by international standards. In 2024, the UK had the third-highest deficit among European countries and the fifth-highest among 36 advanced economies; with its 10-year bond yielding 4.5% as of June 2025, the UK faces the third-highest borrowing costs of any advanced economy after New Zealand and Iceland.
The UK premium on borrowing costs appears to be easing, showing that markets are responding to growing confidence in the government’s fiscal approach.

UK general government net debt rose by 17.9% of GDP between 2019 and 2024, while the average advanced economy had a net debt-to-GDP ratio only 0.7% of GDP higher — an outlier surge driven by aggressive pandemic support and weak post-crisis growth. Debt servicing costs remain elevated despite recent yield compression.
What to Watch
DMO Quarterly Announcements: The next gilt operations calendar for Q1 2026-27 (April-June) will clarify whether the DMO maintains its shorter-maturity bias or tests demand for long-dated paper as curves normalize.
Inflation Trajectory: April CPI data will confirm whether the BoE’s 2% target is within reach, potentially unlocking 50-75 basis points of rate cuts by mid-2026 — a tailwind for gilt auctions.
Auction Coverage Ratios: Bid-to-cover ratios below 2.0x at medium-dated auctions would signal demand fatigue, forcing higher yields or increased reliance on syndications rather than transparent auctions.
Political Commitment Testing: 2027-28 tax rises totaling £15+ billion will face parliamentary scrutiny. Any backtracking would reprice fiscal risk premia across the curve, particularly affecting 2029+ maturities.
Relative Value vs. Bunds: UK-German 10-year spreads currently trade around 50 basis points. Compression below 40bp would validate the consolidation narrative; widening above 70bp would indicate renewed skepticism about delivery.
