Andy Burnham, the frontrunner to replace Keir Starmer as Labour leader, has softened his criticism of bond markets, signalling a more pragmatic approach to fiscal policy. Last year, the Greater Manchester mayor warned that Britain was too “in hock” to bond markets, but now he supports the government’s current fiscal rules and promises a plan to reduce debt.
Understanding the Shift
Burnham’s change in tone comes amid turbulent global markets, with UK borrowing costs rising to their highest since 1998 due to inflation and geopolitical tensions. The yield on long-term UK debt has surged, reflecting investor concerns about political instability and potential increases in borrowing under a new leader.
“I have never said you can just ignore the bond markets,” Burnham told ITV. “I said that politicians have placed Britain in hock because of the way in which we lost control of our finances and public spending.”
Bond Market Realities
The bond market, a £2.9 trillion arena for UK government debt, imposes self-imposed limits on borrowing and debt to reassure investors. Burnham’s earlier comments and radical policy proposals—such as renationalising energy and water—had unsettled City investors, who prefer continuity under Starmer and Chancellor Rachel Reeves.
On Monday, the International Monetary Fund warned that Britain has “limited fiscal space” to deviate from current policies, with debt nearing 100% of GDP and global borrowing costs rising. Adding to elevated borrowing could risk a debt spiral, squeezing out spending on other priorities.
Political Context
The memory of Liz Truss’s short-lived premiership, triggered by a bond market backlash to her mini-budget, looms large in Labour ranks. Burnham’s policy circles suggest that Reeves’s fiscal rules could only be overhauled from a position of strength, and that Labour has more room to adjust tax and spending than currently utilised.
Burnham has floated ideas like increasing borrowing outside the rules to boost defence spending, but these remain vague. As the leadership contest intensifies, his pragmatic stance may persist: not completely subservient to bond markets, but not reckless either.
Ultimately, while the bond market has no vote in Labour leadership, its influence on economic policy cannot be ignored. Burnham’s balancing act reflects the narrow path to power in a politically and economically uncertain environment.
