Britain’s Bond Turmoil Invokes Memory of 1976 Debt Crisis

(Bloomberg) -- Britain’s latest bond turmoil has drawn comparisons with the Liz Truss mini-budget debacle of 2022 but a parallel with the debt crisis of the 1970s might be more apt.

That’s the analysis of former Bank of England rate-setter Martin Weale, who said the Labour government may have to resort to austerity to reassure markets that it will address the UK’s escalating debt burden if sentiment does not change.

Over the past few days, long term UK borrowing costs have soared and the pound has fallen – a rare combination that can signal investors have lost faith in the government’s ability to keep a lid on the national debt and control inflation.

Typically, higher yields would support a currency, but Thursday morning sterling sunk below $1.23 to its lowest level since November 2023, having started the year above $1.25. Still, the currency’s latest struggles are less severe than in September 2022, when it crashed from close to $1.17 to below $1.07 in a couple of weeks.

And Britain’s market troubles are not an isolated case, coming amid a global selloff in bonds.

Nevertheless, Weale said the events echo the 1976 debt crisis “nightmare” that forced the government to ask the International Monetary Fund for a bailout. The current surge in debt costs also threatens to wipe out Chancellor of the Exchequer Rachel Reeves’ slim £9.9 billion ($12.2 billion) buffer against her budget rules and create instability ahead of an official fiscal update on March 26.

Other economists and investors blamed the market moves on skepticism around Labour’s promise to fund a large increase in spending with fastest growth.

“We haven’t really seen the toxic combination of a sharp fall in sterling and long-term interest rates going up since 1976. That led to the IMF bailout,” said Weale, now professor of economics at King’s College London, in an interview with Bloomberg. “So far we are not in that position but it must be one of the chancellor’s nightmares.”

Almost half a century ago, Britain applied to the IMF for a $3.9 billion loan after large budget and trade deficits plunged the country into crisis. In return, the government agreed to IMF-imposed austerity. Britain is today running twin deficits again, and has been for many years.

Borrowing Costs

On Wednesday, 10-year government yields jumped as much as 14 basis points to 4.82%, the highest since August 2008. The pound fell against all major currencies, slumping more than 1% versus the dollar, while UK stocks fell.
