UK loan expenses decrease as Starmer prevents Burnham

Andy Burnham Blocked from Labour Candidacy, UK Borrowing Costs Drop

Andy Burnham, once considered a likely successor to Sir Keir Starmer as Labour leader, has been prevented from running as an MP, leading to a decrease in UK government borrowing costs.

The interest rate on 10-year UK government bonds, known as gilts, dropped to 4.47% early Monday, down from Friday’s peak of 4.51% following news of the Gorton and Denton by-election.

On Sunday, Labour’s National Executive Committee voted eight to one against allowing Burnham to stand in the by-election, effectively removing an immediate challenge to the Prime Minister’s leadership.

Jason Borbora-Sheen, a portfolio manager at Ninety One, noted that markets were experiencing a brief sense of relief, as Burnham now appears less likely to contest Starmer’s position.

Investors had grown uneasy at the prospect of the Manchester mayor seeking Labour’s top job, especially after Burnham suggested that governments should avoid being beholden to bond markets—a comment interpreted as support for increased borrowing and spending if he became Prime Minister.

Andrew Wishart, senior UK economist at Berenberg, explained that a leadership contest could prompt investors to demand higher returns for holding UK debt, fearing a new leader might abandon efforts to reduce the budget deficit.

“A looser approach to public finances would likely push yields higher, as it would stoke worries about inflation and the sustainability of government debt,” Wishart added.

Yields on UK government bonds fell across the board during Monday’s trading, lowering the interest rates the government must offer on new debt.

Last Friday, UK bond yields had risen more sharply than those in other major economies after it was revealed Burnham intended to run in the by-election triggered by Andrew Gwynne’s resignation.

Jim Reid, an analyst at Deutsche Bank, commented that gilts saw “relative relief” on Monday, but cautioned that the issue is unlikely to disappear entirely.

Wishart also suggested that Starmer is likely to be replaced after the local elections in May, but removing Burnham from contention eliminates one scenario that could unsettle the bond market.

He further remarked that any future Labour leader would have limited scope to increase public spending, as the bond market would resist higher borrowing and politicians are unlikely to raise taxes ahead of an election.

Wishart emphasized that Labour “cannot risk a bond market crisis.”

Back in July, yields surged when Chancellor Rachel Reeves appeared emotional in Parliament, sparking investor fears of her possible departure. Borrowing costs eased once the Prime Minister reaffirmed his support for her.
