The long-term borrowing expenses for the UK government have reached their highest point since 1998, driven by escalating fuel prices and worries regarding political stability.
On Tuesday, the yield, which reflects the interest rate, on 30-year UK government bonds (gilts) rose to 5.77% during the midday trading session, marking an increase of 0.13 percentage points and surpassing the peak of 27 years previously recorded last September.
Yields have generally been on the rise among major economies as inflationary fears resurface, particularly following US military efforts to protect shipping in the Strait of Hormuz, which elicited a strong response from Iran.
However, the UK is facing particularly severe repercussions from escalating borrowing costs, exacerbated by uncertainty surrounding the future of Keir Starmer’s government, as some investors have pointed out.
The increase in government borrowing costs will diminish the fiscal flexibility that Chancellor Rachel Reeves has established in relation to the Office for Budget Responsibility’s projections concerning taxation and spending.
In recent days, numerous analysts in the City have released commentary on how the upcoming local elections in England, along with elections in Scotland and Wales, could signify a turning point for Starmer’s leadership and the potential implications for tax and spending policies under possible successors.
Luke Hickmore, the investment director for bonds at Aberdeen Investments, indicated that financial markets are actively factoring in the potential outcomes of the elections. “Politics is not just background noise; it plays a critical role in the current gilt market,” he noted.
Experts have suggested that if Starmer were to be ousted, his potential successors might relax the government’s commitments to fiscal discipline, which could further exacerbate borrowing costs.
Two prominent candidates, Angela Rayner and Andy Burnham, have expressed intentions to adopt a more interventionist economic strategy.
According to Thomas Pugh, chief economist at RSM UK, this is “one reason” for the significant rise in gilt yields. While increased government spending funded by debt could theoretically stimulate short-term growth, it would also likely lead to higher inflation.
Supporters of Burnham, the Mayor of Greater Manchester, informed the Guardian last week that he possesses a feasible strategy to return to Westminster “within weeks.”
On Tuesday, UK bond yields experienced greater movement than those of other major economies, although London markets were closed on Monday for a bank holiday and had not yet reacted to recent events in the Middle East.
The yields on 10-year UK government bonds also increased, rising by 12 basis points, or 0.12 percentage points, to reach 5.09%, the highest level since late March.
Later in the afternoon on Tuesday, yields for both 10-year and 30-year bonds eased slightly, as bond prices typically move inversely to yields.
Last week, the Bank of England cautioned about inflation rates surpassing expectations, opting to maintain interest rates at 3.75%, while signaling that action may be necessary in the coming months to manage rising prices.
Since the onset of the conflict, petrol prices have surged, and it is anticipated that rising costs for energy and fertilizers will soon permeate the broader economy.
Andrew Bailey, the governor of the Bank of England, remarked last week that “the direction we take from here will be influenced by the magnitude and duration of the energy price shock” as the conflict progresses.
He added, “The longer this issue persists and the longer energy supply disruptions continue, the more challenging our situation will become.”
As a major energy importer, the UK is particularly vulnerable to inflationary pressures stemming from the Middle East compared to other large economies. The International Monetary Fund recently cautioned that an escalation in the Iran conflict would have a more pronounced impact on the UK than on other G7 nations.
Markets are beginning to reflect a more precarious outlook for the UK than the headline statistics might indicate, according to Lale Akoner, an analyst at eToro, who pointed to the “combination of political uncertainty, energy vulnerability, and fiscal pressure.”
“If uncertainty continues, upward pressure on yields is likely to persist, with broader implications for borrowing costs and financial conditions throughout the economy,” Akoner concluded.
