22nd June 2026
The financial markets are displaying classic symptoms of political whiplash as the news of Starmer’s exit hits the trading floors.
While London's equity markets have largely remained in a cautious "wait-and-see" pattern, the currency markets have taken an immediate hit.
The Pound Under Pressure
In direct response to the Downing Street announcement, the British Pound dropped 0.3% to $1.319 US Dollars and slid 0.1% to €1.152 Euros.
This rapid dip leaves Sterling hovering precariously near its absolute lowest level of 2026, reflecting the currency market's deep dislike of political uncertainty.
Muted Stock Market Response
Unlike the chaotic bond market crashes seen under Liz Truss in 2022, the blue-chip stock index remained remarkably steady. The FTSE 100 Index dipped by just over five points to 10,357.88 in morning trading.
City analysts note that a Starmer exit timetable had already been largely "priced in" by big institutional investors over the weekend as rumors of the cabinet mutiny leaked.
The Gilt Market Warning
The true test of economic stability will lie in UK government bonds (gilts). While 10-year gilt yields held steady at 4.84%, they remain close to their highest levels since the 2008 financial crisis.
Investment strategists warn that the market will demand a premium if Andy Burnham or any other successor signals an intention to loosen the current chancellor's strict public spending rules to fund their new political vision.
