As the Labour Party gears up for a potential leadership contest following Andy Burnham’s decisive victory in the Makerfield by-election, economists are voicing apprehensions about the implications for UK government borrowing costs. With Burnham’s commitment to tackling the cost of living crisis, analysts warn that this could lead to increased borrowing, subsequently driving up bond yields.
The Implications of a Leadership Race
Dan Coatsworth, head of markets at AJ Bell, highlighted the possibility of rising gilt yields if current leader Keir Starmer remains in the fray. “Friday’s moves reflect the risk that Starmer won’t go quietly,” Coatsworth noted, indicating that investor sentiment remains cautious amidst the political uncertainty. The current increase in yields is not only a reaction to the Labour dynamics but is also influenced by external factors, such as recent setbacks in US-Iran negotiations that have sparked a rise in oil prices and sustained inflation concerns.
This morning, the yield on 30-year UK bonds climbed by 8 basis points to 5.529%, marking a significant uptick although still below the peak of 5.89% reached in May. This fluctuation underscores the volatility in the bond market, with yields serving as a barometer for the cost of new debt issuance.
The Role of Domestic Political Risk
According to analysts Alexandros Xenofontos and Christopher Granville from TS Lombard, the return of domestic political risk is a crucial factor influencing the gilt market. “The question for gilts is whether the next Labour leadership preserves the Starmer-Reeves fiscal bastion, shifts left through funded tax-and-spend, or starts testing the fiscal rules,” they explained. Investors are now faced with the uncertainty surrounding a leadership change, particularly with Burnham being perceived as the least market-friendly candidate.
Neil Wilson, an investor strategist at Saxo UK, observed that market participants are already reacting to the implications of Burnham’s rise. “There’s a natural uncertainty that surrounds a leadership race,” he said, noting that a potential leftward shift in government policy could further unsettle the bond market.
What Lies Ahead for the Bond Market
The prospect of Burnham taking over from Starmer raises additional questions about Labour’s direction and its broader impact on fiscal policy. Should Burnham secure the leadership role, there’s speculation he might call for a snap general election, a scenario that could send shockwaves through the bond market.
Coatsworth highlighted that an early general election, particularly if Labour were to lose power to the Reform Party, could exacerbate market volatility. “Investors would likely demand a higher yield to compensate for the increased risk associated with a Reform government,” he cautioned. The lack of clarity regarding Reform’s policies could further contribute to investor anxiety, leading to higher bond yields and potential instability in the pound.
Why it Matters
The outcome of the Labour leadership race could have far-reaching implications for the UK economy and its bond market. The spectre of rising borrowing costs could place additional pressure on government finances, particularly as the country grapples with ongoing inflation and a cost of living crisis. Investors are watching closely, as any shifts in policy direction could significantly alter the landscape for UK bonds, influencing everything from government borrowing to everyday consumer spending. In a climate where financial stability is paramount, the stakes have never been higher for both the Labour Party and the markets.
