The Brewing Storm Over Burnham’s Budget

The recent spike in gilt yields has brought a sense of déjà vu to the UK’s economic landscape, as governments worldwide grapple with rising energy costs, inflation, and debt burdens. Britain is once again caught on the wrong foot, and Andy Burnham’s government faces an unenviable task: convincing bond investors that their fiscal plans are worth taking a chance on.

The Iran war has sent shockwaves through the energy markets, while US treasury secretary efforts to calm nerves have so far been unsuccessful. Yet the UK is already uncomfortably positioned on the borrowing costs spectrum, with yields at their highest since 1998, as noted by Nils Pratley in his recent article. This skepticism is palpable in the bond market, which met Burnham and Chancellor John Healey’s Commons speech earlier this week with a lukewarm response.

Investors are still awaiting tangible evidence of the government’s commitment to fiscal discipline. Simon French, an economist at Panmure Liberum, warned that markets are skeptical about the practical implications of devolution and control over utilities. While Burnham emphasizes public control as a popular theme in Labour circles, there is little indication it will lead to substantially lower costs for building infrastructure – a pressing concern given the UK’s dismal track record on keeping inflation under control.

The bond market’s expectations for next month’s budget are high, and it remains to be seen whether Burnham and Healey can deliver. Their speech was far from reassuring, and investors will closely watch as they outline plans for addressing energy costs, social care, housing shortages, and other pressing challenges.

Labour cannot afford to disappoint the bond market again after a tumultuous 2026 marked by leadership changes and economic uncertainty. Burnham’s promise of giving businesses and consumers breathing space from cost-of-living pressures will only be credible if his government can get its finances in order. As Jim O’Neill, a former Goldman Sachs economist, noted, high borrowing costs may force Labour to confront tough decisions – including the triple lock on the state pension and welfare spending.

It’s time for Burnham and Healey to prove they are up to the task. They must demonstrate that their fiscal plans are grounded in reality and will not exacerbate the UK’s economic woes. The bond market will be watching closely, and any sign of complacency or lack of urgency will be met with skepticism.
