UK long-term borrowing costs hit 28-year high ahead of Budget

Borrowing costs surge to multi-decade highs

Long-term government borrowing costs have risen sharply, reaching levels not seen in 28 years, adding pressure on Prime Minister Andy Burnham and Chancellor John Healey ahead of next month's Budget.

The yield on 30-year UK government bonds – known as gilts – jumped by 10 basis points to 5.89% on Tuesday morning, the highest level since March 1998, as reported by the Evening Standard. The yield on the benchmark 10-year gilt also rose to as much as 5.223%, the highest rate since June 2008, at the height of the global financial crisis, according to the same report. Gilt yields move inversely to bond prices, meaning prices fall as yields rise.

Higher rates on government bonds mean it will cost the government more to borrow, the Evening Standard reported. This reduces the headroom the government has against its self-imposed fiscal rules, limiting the amount the Chancellor can spend on measures to ease the cost of living, as reported by the BBC.

The rise comes amid a widespread global bond sell-off, with the Evening Standard attributing the uptick in yields partly to signs of escalation in the Middle East and concerns that inflation could accelerate in the coming months, potentially leading central banks to lift interest rates.

Global context and market drivers

The increase in UK borrowing costs reflects broader international trends. Japan's 10-year bond yield swung to its highest since 1996 on Tuesday after rising above 3%, the Evening Standard reported. The BBC noted that global markets reacted after suggestions in the US that the central bank could raise rates, with Japan also facing pressure to raise rates. The UK market was closed for the bank holiday on Monday, according to the BBC.

Oliver Faizallah, head of fixed income research at Raymond James, offered a market perspective, saying: "While elevated bond yields are warranted given the inflationary and fiscal risks that are very clear and present, I also believe that the recent sell-off is fully pricing in these risks. As it stands, bond yields are priced for higher and prolonged second round inflation, consequent central bank hikes, and further government spending driven by an increase in bond sales. With the bad news in the price, there is a limitation to how much further bond yields can keep climbing."

Government response and fiscal outlook

A government spokesperson said the government will meet the fiscal rules with a buffer against uncertainty and is cutting the deficit faster than any other G7 economy, as reported by the BBC. The Prime Minister's official spokesman, quoted by the Evening Standard, declined to comment on market movements, saying: "We don't comment on markets. More generally, I would just say that fiscal discipline is the bedrock of economic stability and national security."

The Chancellor is currently in the United States attending a G20 meeting of global finance ministers and central bankers, the BBC reported. At the meeting, Healey told counterparts that the UK had the fastest growth in the G7 so far in 2026, that productivity was improving, and that the UK was cutting borrowing at the fastest rate among major economies.

Political implications

Prime Minister Andy Burnham faces his first Budget next month, and the higher borrowing costs are expected to make the Budget process more difficult, according to the BBC. Burnham will face MPs on Tuesday for the first time as prime minister, the BBC reported.

An unnamed analyst quoted by the BBC said that while the UK is used to pockets of volatility, record levels of government debt and a record tax take mean "these are not comfortable times for the new government and the new chancellor."
