The UK economy managed a meager 0.1% expansion in May, reversing the prior month's slight contraction, but the headline figure masks a sharp divergence between services and the goods-producing sectors. The Office for National Statistics reported that services output rose 0.3% from April, while industrial production fell 0.5% and construction dropped 0.8%.
The reading matched economists' expectations, according to a Reuters poll, and followed a 0.1% decline in April. Over the three months to May, the economy grew 0.7%, and annual output was 1.3% higher than a year earlier — the strongest year-on-year gain in ten months.
Services Carry the Load
The services sector, which accounts for roughly 80% of UK economic output, was the sole engine of growth in May. The ONS highlighted strength in computer programming and advertising, along with a jump in pharmaceutical-related activity, specifically medical research and development. That pharmaceutical pop is often volatile, the agency noted, so it may not persist.
Meanwhile, factories and building sites struggled. Industrial production fell 0.5% month-on-month, and construction output dropped 0.8%. The weakness in goods-producing industries suggests that higher interest rates and lingering supply-chain frictions are still weighing on manufacturing and building activity.
Clouded Outlook: Politics and the Strait of Hormuz
The economic backdrop remains uncertain. Political churn continues to unsettle businesses and consumers, with the UK having seen another change of prime minister. Such instability can delay investment decisions and dampen confidence.
Adding to the risks, the ONS noted that UK imports of refined oil from Saudi Arabia, Kuwait, and Qatar fell to zero in May, following the closure of the Strait of Hormuz — a critical chokepoint for global energy shipments. The disruption, tied to heightened tensions in the Gulf, threatens to push up energy costs for UK businesses and households.

What It Means for Investors
A 0.1% GDP rise does not automatically translate into a broad stock market rally. The composition of the UK's main indexes matters. The FTSE 100 is dominated by multinational companies that earn a large share of their revenue overseas, so their profits are more sensitive to global demand and currency moves than to a single month of domestic activity. The FTSE 250, by contrast, includes more mid-sized firms tied to the UK economy, making it more responsive to home-grown services growth.
When the ONS flags pockets like computer programming and advertising as drivers, the market read-through is likely to be narrower and more UK-services-facing than the headline GDP number suggests. Investors should watch for earnings reports from companies in those sub-sectors for confirmation of the trend.
The broader economic picture also matters for interest rate expectations. The Bank of England has been raising rates to combat inflation, and a sluggish economy could reduce pressure for further hikes. However, the risk of higher energy costs from the Gulf disruption could keep inflation elevated, complicating the central bank's path.

In summary, May's data shows a services-led economy that is barely growing, with industrial and construction sectors in retreat. The combination of political uncertainty and potential energy supply shocks means the outlook remains fragile. For everyday investors, the key takeaway is that UK-focused services stocks may offer some resilience, but the broader market faces headwinds from both domestic and international risks.
