UK political tensions: Pound holds steady, for now

November 13, 2025

Reports of a leadership rift at the core of the UK government have kept the pound steady for the moment, although investors are beginning to wonder how long this stability will endure.

Leadership Rumours Stir Market Unease

Health Secretary Wes Streeting has dismissed suggestions that he is manoeuvring to succeed Prime Minister Keir Starmer, though the speculation has renewed discussions about internal divisions within the government at a politically sensitive time.

The rumours surface ahead of a crucial Budget on 26th November, amid mounting concern over possible tax increases to address a £30 billion fiscal shortfall.

Markets are keeping a close eye on Westminster.

As I was quoted by CNBCLondon Loves BusinessLondon Daily NewsShare Café, and Business Money, amongst other media, rumours of government leadership changes emerging ahead of a pivotal Budget add to the perception that the administration is under pressure.

Investors have not yet priced in political instability, but they remain wary of the possibility that the issue could resurface in the new year.

We believe that an immediate leadership challenge following the Budget is unlikely, as the focus will be on navigating it smoothly. However, this will be particularly challenging given that income tax increases now appear almost certain.

The bigger risk of a leadership challenge is expected in May, following the local elections.

If Labour underperforms, internal pressure is likely to mount, potentially triggering a full-scale leadership contest.

Markets Watching for Signs of Instability

The issue extends beyond just Starmer personally.

Prime Minister Starmer and Chancellor Reeves are closely linked politically. Investors view them as a unified fiscal team that brought back economic discipline after years of instability. We believe that if one were to depart, the other could follow, a scenario that would likely rattle markets immediately.

The pound remains resilient for the moment, but this stability hinges on confidence that the government will deliver a credible Budget and maintain political cohesion ahead of next year’s local elections.

If investors start sensing the possibility of a leadership change mid-next year, that stability is likely to dissipate.

Global investors have short patience for any renewed uncertainty.

Bond traders, in particular, recall the 2022 gilt turmoil clearly. Any indication that the government’s fiscal path might shift would drive yields up, as markets seek a premium for political risk.

The pound would weaken as international investors redirect their capital elsewhere.

Calm May Prove Short-Lived

The coming months will be a test of whether the government can maintain stability while enforcing fiscal discipline.

The Budget will focus on figures, but markets are primarily concerned with credibility and continuity.

They are unlikely to tolerate any leadership upheaval.

If the Budget is poorly received and party polling declines through the spring, speculation over leadership will gain traction.

At that point, the political risk premium could widen, initially in gilts, then in sterling. Once confidence in leadership continuity is lost, this shift can occur very rapidly.

The pound’s current stability may be short-lived, reflecting hope that leadership rumours remain subdued.

Investors are monitoring the situation closely, knowing that this calm could unravel suddenly, particularly with the crucial Budget approaching and heightened uncertainty ahead of next year’s local elections.
