UK Manufacturing PMI: Industry returns to output contraction as cost pressures surge

UK manufacturing output fell back into contraction in March, as rising geopolitical tensions and surging input costs weighed on production and business confidence.

The latest S&P Global UK Manufacturing PMI registered 51.0 in March, down from 51.7 in February, signalling a slower improvement in overall operating conditions despite remaining above the 50.0 threshold for a fifth consecutive month.

Output declines as uncertainty bites

Production decreased for the first time in six months, driven primarily by a solid contraction in the intermediate goods sector. This outweighed modest growth among consumer and investment goods producers.

Manufacturers cited growing uncertainty linked to geopolitical tensions, particularly the war in the Middle East, alongside concerns around domestic economic policy. These factors contributed to reduced output, cautious stock management, and weaker confidence among both firms and their clients.

Business optimism also deteriorated sharply, with expectations for future output falling at the fastest rate in a year and dropping to their lowest level since September 2025.

Supply chain stress and costs intensify

The survey highlighted significant pressure on supply chains, with vendor delivery times lengthening to the greatest extent since mid-2022. This was largely attributed to disruptions linked to the Middle East conflict and ongoing global shipping challenges.

At the same time, input price inflation surged to a 41-month high. Nearly half of manufacturers reported rising purchase costs, driven by increases in energy, oil and gas prices.

These cost pressures, combined with material shortages, were identified as key constraints on production.

Demand shows relative resilience

Despite the challenging backdrop, demand conditions remained comparatively stable. New orders increased for a fourth consecutive month, supported by growth in both domestic and export markets, including the US, Europe and Asia-Pacific.

However, some firms reported squeezing margins to secure new business, even as selling prices rose at the fastest pace since May 2025.

Employment falls as confidence weakens

Rising costs and uncertainty also fed through to the labour market, with employment declining at the fastest pace since September 2025.

Commenting on the data, Rob Dobson, Director at S&P Global Market Intelligence, said: “UK manufacturing output contracted for the first time in six months in March, as the war in the Middle East and ongoing concerns about domestic economic policy led to a scaling back of production.”

He added that supply chain disruption and rising costs had created “a high-cost environment and shortages of inputs,” further constraining output.

Dobson also noted that while new orders remained relatively resilient, “it’s hard to see how demand can prove resilient in the face of current high energy prices and economic uncertainty unless there’s a swift resolution to the war in the Middle East.”

However, Dobson highlighted that the drop in production is currently more of a supply issue than one caused by an outright downturn in demand.

Outlook remains uncertain

While the PMI headline figure suggests continued overall expansion, the underlying data points to a sector under increasing strain.

With cost inflation accelerating, supply chains under pressure, and confidence weakening, the outlook for UK manufacturing remains closely tied to geopolitical developments and the trajectory of energy prices in the months ahead.
