Rising Bills, Rising Pressure: what the Iran war means for Starmer’s position

The escalating conflict in the Middle East may appear distant from UK domestic politics, but its most immediate impact could be felt in the everyday costs facing ordinary voters.

Rising petrol prices are already being felt in UK voters’ pockets, and rising energy prices will almost certainly come over the coming months. For a country that relies in part on fuel and energy imports, disruption in the Middle East quickly feeds through to global markets, ultimately landing in consumers’ pockets through higher household bills and transport costs.

But the consequences do not stop there. Higher energy costs risk pushing inflation back up, reversing its downward trajectory. That matters for the Government, because the UK economy has been slowly emerging from a prolonged period of high inflation and rising borrowing costs. Any renewed price pressures could complicate the Bank of England’s path on interest rates and in turn the Chancellor’s expected policy announcements at her upcoming Mais lecture, particularly if markets begin to believe inflation will remain stubborn for longer than expected.

The knock-on effects are already being felt in the housing market. Mortgage pricing is closely tied to expectations about future interest rates, and in recent days lenders have begun to pull products and reprice fixed-rate deals as markets reassess the outlook. If this trend continues, homeowners and prospective buyers could face higher borrowing costs just as confidence in the housing market had begun to stabilise.

For the Government, the political risk is not simply higher prices, but what they represent. Sir Keir Starmer’s central economic argument has always been one of stability and responsible management after years defined by inflation and the cost-of-living crisis. Public polling suggests that around 40% of voters do not want the UK to join any military action in the Middle East, compared to the 11% that do. That gives Starmer a potential political shield: by choosing not to enter the conflict, he can argue that the Government is protecting households from the additional costs that war would have brought, reinforcing his broader cost-of-living narrative.

At the same time, this positioning allows Starmer to appear as a strong national leader, taking a measured, sensible approach in contrast to the more hawkish or inconsistent stances of figures like Angela Rayner, Kemi Badenoch or Reform UK. By prioritising domestic economic stability, he can claim the mantle of reasoned leadership, making him look decisive and responsible while others risk appearing reckless or opportunistic.

The real risk, however, is one of momentum. If voters begin to feel pressure on everyday costs again, just as the Government has been arguing that the worst is over, it could quickly erode confidence in the Government’s growth agenda. Even if the causes lie overseas, the political pressure will land squarely on Starmer’s Government at home.
