UK gilts sell off as Starmer faces cabinet exodus

UK gilts have sold off amid political turmoil in Westminster, with dozens of Labour MPs and Cabinet allies calling on Prime Minister Keir Starmer to step down following heavy losses in last week's local elections. Starmer has defied resignation calls and told Cabinet he intends to stay, but the erosion of his political capital threatens policy continuity and the credibility of the fiscal framework. Gilt yields are rising as investors reprice the risk of political dysfunction amid an already fragile economic backdrop.

The timing of the political crisis coincides with energy shocks from the Iran ceasefire fragility, creating a double headwind for UK financial assets. The pound sterling weakened sharply during US Treasury Secretary Scott Bessent's visit to Japan, suggesting broader sterling weakness as capital flows out of UK assets. ECB officials including Christodoulos Patsalides have signaled readiness for rate hikes at the June meeting, creating potential divergence with UK policy if the Bank of England remains on hold while continental Europe tightens.

Implications extend beyond UK gilts. Political instability raises the cost of government financing and weakens the pound, which in turn pressures import prices and inflationThe rate at which prices rise across an economy. expectations for the UK economy. Cabinet-level departures could signal early elections, which would inject months of policy uncertainty and reduce the government's ability to implement spending or tax changes. European equities and sterling-denominated assets face headwinds if the political situation deteriorates further.

Market structure suggests gilts could find some support if the political crisis stabilizes quickly or if Starmer consolidates support. However, the combination of political risk, energy inflationThe rate at which prices rise across an economy., and potentially higher ECB rates creates a challenging environment for UK assets near-term. Any escalation in resignations or early election calls would trigger further gilt selling.
