Sharp Decline in Business Activity: Composite PMI Falls to 48.5
The S&P Global flash UK Composite PMI for May 2026 fell to 48.5, down from 52.6 in April – the first sub-50 reading since April 2025. The services sector, which makes up 80 % of GDP, recorded its steepest decline since January 2021, and private-sector payrolls fell for the twentieth month in a row.
Headwinds from Iran Conflict and Domestic Uncertainty
Surveyed firms cited two headwinds: the Iran war and the closure of the Strait of Hormuz, which have lifted oil prices and disrupted supply chains; and political uncertainty around Prime Minister Keir Starmer’s leadership, raising business risk and curbing investment and hiring.
Key Data Points
- Composite PMI: 48.5 (May) vs. 52.6 (April).
- Services PMI: weakest since Jan 2021.
- Private-sector employment: down 100,000 in April, steepest fall since 2014.
- CPI inflation 2.8 % in April (down from 3.3 % in March) and BoE policy rate held at 3.75 %.
Official Responses
Bank of England kept its 3.75 % rate unchanged and, with an 86 % probability of no change at June 18 meeting, cited evidence that inflation is falling. S&P Global said the PMI drop reflects a ‘perfect storm’ of geopolitics and domestic politics. CBI noted a rise in manufacturing orders but warned order books are at their lowest since 2020. Office for National Statistics said payroll decline is driven by service-sector job losses.
The Slowdown Is Not Solely War-Driven
The slowdown is not solely war-driven. Henry Cook of MUFG Bank warned oil prices have reshaped inflation expectations, making a near-term rate cut less likely. Paul Dales of Capital Economics noted weaker activity may be tempering price growth, easing pressure on the Bank of England to raise rates quickly.
Conflicting Reports and Gaps
Guardian calls the services slump the sharpest since Jan 2021, while Reuters notes first sub-50 composite reading since April 2025. CBI cites a manufacturing upturn, yet its data show order books at their lowest since 2020. Flash PMI is provisional; final figures could alter the contraction’s magnitude.
Outlook: Policy Decisions and Economic Forecasts
The BoE’s June 18 meeting is likely to keep rates steady, with an 86 % chance of no change. Spring Budget measures may support services. Escalation in the Iran conflict or domestic political turbulence could deepen the contraction, while a de-escalation in Middle East might ease energy-price pressures and aid recovery.
