The pound climbed modestly on Monday yet remained near its lowest point since early April, as investors weighed concerns about rising inflation linked to higher energy prices alongside political instability in Britain.
Pressure on Prime Minister Keir Starmer intensified after disappointing local election outcomes earlier in May, a political disruption that has coincided with a sharp rise in gilt yields and added downward pressure on sterling.
The Labour Party suffered significant losses on May 7, prompting nearly a quarter of Labour lawmakers to call for Starmer to step down. The emergence of two declared rivals vying to replace him has unsettled markets and contributed to an increase in the government’s borrowing costs.
"I am focused on the job that I was asked to do, which is to serve my country and to carry out my duties as prime minister of this country," Starmer said during a visit to the Labour Party’s headquarters.
On the foreign exchange market, sterling was last reported up 0.4% on the day at $1.337, after earlier dropping as much as 0.15% to $1.3304 - its lowest level since April 8. The modest intraday gain left the currency still close to the recent trough established in early April.
Underlying the currency moves, UK gilt yields surged to multi-year highs last week as investors expressed concern that a potential left-leaning successor to Starmer might seek to expand government borrowing in order to stimulate growth. That scenario, market participants say, would place additional strain on Britain’s already fragile public finances.
Taken together, the interplay of energy-driven inflation risks and political uncertainty has created a fragile backdrop for sterling and for UK government bond markets. Traders and investors remain attentive to further domestic political developments and to any shifts in energy price dynamics that could influence inflation expectations.
Market context: The movement in sterling reflects a combination of macroeconomic and political drivers rather than a single identifiable catalyst - with both higher energy prices and leadership instability cited as contributing factors.
