UK government debt sales are expected to fall in the financial year ending March 2027, the first annual decline in four years and a sign that efforts to contain borrowing are starting to ease pressure on the gilt market.
On an average of forecasts from major investment banks, gilt issuance is projected at roughly £247 billion in 2026-27, down from the £304 billion the government is raising in the current financial year. If realised, it would be the first drop in issuance in four years and the lowest annual total in three. Independent estimates cluster in a similar range, with some forecasters placing the figure slightly above £250 billion.
Why issuance is set to fall
Two factors are driving the expected decline. The first is a smaller refinancing requirement: less existing debt matures in 2026-27 than in recent years, reducing the amount the government must roll over. The second is a lower overall borrowing need, helped by the tax increases announced the previous autumn, which have lifted receipts. The reduction is expected to be confirmed in the government’s spring forecast for the public finances, the first such update since the prior fiscal year.
Public finances running ahead of forecast
Recent data has reinforced the picture. Figures from the Office for National Statistics showed borrowing of about £112.1 billion over the ten months to January 2026, roughly £8.3 billion below the £120.4 billion the Office for Budget Responsibility had forecast for the period. Stronger-than-expected tax receipts were the main reason, giving the Chancellor more room to manoeuvre. The improvement has not been uniform, however: borrowing in April 2026 came in above the OBR’s forecast and ranked among the highest for that month on record, a reminder that the trend is not a straight line.
Calmer gilt markets
Investor sentiment toward gilts has improved. The gap between gilt yields and equivalent interest-rate swaps, a gauge of concern about an oversupply of debt, has narrowed to levels last seen before the government’s first budget in late 2024, when gilts had sold off sharply. The government has also reduced the share of long-dated debt it issues, which has helped keep long-term borrowing costs in check. Lower yields, in turn, offer a modest improvement to the headroom the Chancellor has against her main fiscal rule.
The risks that remain
Even so, several economists caution against reading too much into the improvement. Gilt issuance remains very high by historical standards, and the better near-term figures owe much to one-off strength in receipts rather than a structural shift. Analysts also note that political pressure to increase spending has not faded, and that fiscal headroom built on favourable market conditions can erode quickly if growth disappoints or borrowing costs rise again. A single year’s decline in issuance, while welcome, does not by itself put the public finances on a markedly lower debt path.
Why it matters
Gilt issuance sits at the intersection of government policy and financial markets. It determines how much new debt investors must absorb, which in turn influences borrowing costs across the economy, from mortgage rates to corporate financing. A smaller, better-received supply of gilts signals stabilising confidence, but with totals still elevated and sensitive to the political and economic backdrop, the spring forecast and the monthly borrowing data that follows remain important markers to watch.
