The UK markets showed a measured response after Prime Minister Keir Starmer announced plans to step down, as investors weighed whether a future Labour government could reignite concerns over Britain’s fiscal outlook.
The British pound continued to hold losses, while government bonds (gilts) traded at stable levels. The UK’s 10-year bond yield remained almost unchanged at 4.85%, while sterling slipped 0.1% against the US dollar to $1.3223.
Political agenda under scrutiny
Starmer’s decision opens the way for Manchester Mayor Andy Burnham, who entered Parliament last week, to potentially succeed him. Investors are now focusing on what a change in leadership could mean for economic policy and whether any shift in fiscal strategy could affect borrowing and spending plans.
Pooja Kumra, Head of UK and European Rates Strategy at Toronto Dominion Bank, said markets are now focusing on Burnham’s political priorities within an already restricted fiscal environment.
Burnham, considered the leading contender, has yet to outline detailed policy positions, leaving uncertainty over future borrowing requirements. Investors remain cautious about the possibility of increased government bond issuance to fund spending, especially as the UK continues to face debt pressures.
Transition period may ease volatility
The nomination process for the leadership race will begin on 9 July and conclude by 1 September, with Starmer remaining in office during the transition period.
Kumra noted that the extended transition period could reduce short-term political volatility, although market focus may intensify closer to September.
British bond yields have fallen in recent weeks following optimism over a potential US-Iran peace agreement. Last month, yields climbed to an 18-year high as Middle East tensions pushed oil prices higher and raised inflation concerns.
Political risk already priced in
Analysts believe investors are reacting calmly because political risk has largely already been priced into UK assets following the market turmoil during the period of former Prime Minister Liz Truss.
Skylar Montgomery Koning, an analyst at Bloomberg, said investors currently view developments surrounding Burnham more as political noise than a direct threat to fiscal credibility.
Sterling has also faced pressure from expectations that the Bank of England could move more slowly on interest rate increases than the US Federal Reserve this year. The pound has weakened around 2.5% since the 7 May election.
Options traders have also positioned for further weakness in sterling, with market sentiment indicators remaining bearish.
Steve Brice, Chief Investment Officer for Group Wealth Management at Standard Chartered in Singapore, said political uncertainty could create investment opportunities but added that markets would likely challenge any aggressive spending plans.
Meanwhile, ING strategist Francesco Pesole said sterling currently appears fairly valued against the euro in the short term, though renewed concerns over fiscal policy could increase downside risks.
