UK economic growth to slow next year amid Middle East conflict impact

UK economic growth is on course to slow next year as fallout from the Middle East conflict hits energy markets and weighs heavily on activity across industrialised nations, international forecasters have warned.

The revised projections from the Organisation for Economic Co-operation and Development (Yahoo! Finance Canada) and the International Monetary Fund (BBC) present a complex picture for the government’s wider business agenda. Although the UK economy performed better than previously anticipated through parts of the year, renewed geopolitical turbulence in the Middle East has injected fresh volatility into global oil and gas prices.

According to Independent reporting, the UK economy is estimated to have grown by 1.1% for the current year, marking an upgrade from earlier estimates of 0.9% driven by solid domestic demand in the second quarter. Yet growth is anticipated to moderate to 1% next year as higher fuel and energy prices eat into activity (Yahoo! Finance Canada).

International agencies differ slightly on the exact scale of the slowdown. While the OECD projects a moderate dip to 1% growth for next year (Yahoo! Finance Canada), the BBC reported that the IMF warned the UK faces the single biggest hit to growth from the Iran war among major advanced economies, citing the country's status as a net energy importer (BBC). The IMF noted that higher energy prices and fewer interest rate cuts will linger into future quarters (BBC).

Inflation figures remain a central battleground. Energy prices eased over the summer during a temporary ceasefire period, but surged notably higher after hostilities resumed (Independent). Consumer price inflation climbed to a five-month high of 3.1% recently, and the Bank of England has cautioned that the rate could climb further toward 4% in early 2027 before gradually easing (Independent). The OECD now expects UK inflation to settle at 2.6% next year, representing a shallower drop than previously forecast (Independent).

Global factors continue to exert a powerful cross-current. As Aol notes, robust spending on artificial intelligence infrastructure—ranging from data centres to advanced semiconductors—has provided a vital pillar of global resilience this year, helping offset sluggish consumer spending in certain territories. Nevertheless, energy market jitters and extreme weather tied to El Niño threaten to cloud the wider economic horizon (Aol).

Political figures have traded sharp blows over the implications of the forecasts. Treasury minister Emma Reynolds defended the administration's record, stating: Despite unprecedented pressures and conflict in both the Middle East and in Europe, the UK economy is showing strong resilience. She added that the government is focused on long-term structural changes to foster job creation across every postcode (Independent).

Conversely, opposition critics argue that domestic policy choices have compounded external shocks. Shadow chancellor Sir Mel Stride claimed that tax adjustments, including changes to employers' National Insurance and business rates, have left businesses exposed and contributed to persistent cost pressures (BBC). Meanwhile, international economists have cautioned governments against deploying unbudgeted fiscal stimulus to offset energy bills, noting that tight public finances leave little room for manoeuvre (BBC).
