Sterling slipped 0.1% to $1.3223 after Prime Minister Keir Starmer announced his resignation, while UK 10‑year gilt yields held at 4.85%. Traders weighed the prospect of a new Labour leader reshaping fiscal policy, fearing any shift could widen the government's already tight borrowing capacity. The market’s calm reflects uncertainty over who will assume the premiership and the Treasury suite. Investors will watch Chancellor appointments closely.

The frontrunner, Greater Manchester Mayor Andy Burnham, secured a parliamentary seat in the Makerfield by‑election, positioning him for the September leadership contest that opens July 9. Burnham has offered little detail on spending plans, leaving investors nervous about potential bond issues. Toronto Dominion’s Pooja Kumra warned that fiscal space remains highly constrained, keeping yields sensitive.

With the transition set to span weeks, market strategist Kumra expects political risk to recede while structural fiscal concerns dominate the curve. Standard Chartered’s Steve Brice sees the current lull as a buying window only if a sell‑off materialises, noting that a spend‑heavy agenda would quickly reshape sentiment. Sterling’s short‑term valuation against the euro suggests limited upside unless fiscal discipline improves.
