UK Manufacturing Hit by Rising Costs & Iran War Uncertainty | City A.M.

UK manufacturers are facing their most significant cost pressures in over three and a half years, according to new data released Wednesday. The squeeze, driven largely by the escalating geopolitical tensions in the Middle East and the resulting surge in energy prices, is impacting production and dampening business confidence. The situation echoes the challenges faced in late 2022 following Russia’s invasion of Ukraine, but with a potentially more protracted impact given the current instability in the region.

The latest research from S&P Global reveals that input prices for manufacturers rose at the fastest rate since December 2022. This increase isn’t simply a reflection of energy costs. it’s a broader inflationary pressure impacting raw materials and transportation. Perhaps more concerning, the pace of price increases is the steepest seen since the sterling crisis of 1992, highlighting the severity of the current economic climate. The manufacturing sector, a key component of the UK economy, is now grappling with a complex interplay of geopolitical risk, rising costs and weakening demand.

UK manufacturing costs soared in March.

The primary driver of these escalating costs is the disruption to global energy markets stemming from the ongoing conflict in the Middle East. Oil prices have surged over 70% since the start of the conflict, directly impacting production and transportation expenses for manufacturers. This increase isn’t isolated; natural gas prices have also experienced significant volatility, further exacerbating the cost burden. Manufacturers are reporting that these rising energy costs are not only impacting their bottom line but are also beginning to influence buyer demand, with some customers delaying or reducing orders.

Output Slowdown and Supply Chain Concerns

The impact of these pressures is already visible in manufacturing output. S&P Global’s survey data indicates a decline in overall production, with the initial momentum experienced in previous months now “hitting the buffers,” as one economist put it. The contraction in output is particularly pronounced in the production of intermediate goods – components used by other manufacturers – suggesting a ripple effect throughout the supply chain. This slowdown is directly linked to the uncertainty surrounding the geopolitical situation and the potential for further disruptions to energy supplies.

Mike Thornton, head of industrials at the accountancy firm RSM, emphasizes the squeeze on demand. “Demand is being squeezed. New orders have ticked down, leaving the sector feeling pinched,” he said. He further highlighted the strategic importance of the Strait of Hormuz, a critical waterway for global oil shipments, stating, “The control of the Strait of Hormuz is one of the biggest commercial issues for manufacturers and issues will pile up the longer access is blocked.” The potential for prolonged disruption to this vital shipping lane is a major concern for businesses reliant on imported materials and components.

A Shift Towards ‘Permanent’ Cost Adjustments?

Beyond the immediate pressures, there’s a growing concern among manufacturers that the current cost increases may not be temporary. Cara Heffey, industrials and services chief at PwC UK, notes a shift in mindset among business owners. “Manufacturers will be starting to reckon less about immediate disruption and more about their options in the longer-term,” she explained. “With businesses dealing with the shock waves from rising energy prices, delivery times lengthening and cost pressures intensifying, they are weighing up whether to hold additional precautionary stock, rethink logistics routes, or accept higher input costs as a more permanent feature rather than a short‑term shock.”

This potential for a ‘permanent’ shift in cost structures is prompting manufacturers to re-evaluate their strategies. Some are exploring options for nearshoring or reshoring production to reduce reliance on global supply chains, even as others are investing in energy efficiency measures to mitigate the impact of rising energy costs. However, these adjustments require significant investment and time, and may not be feasible for all businesses.

PMI and Business Sentiment

Despite the challenges, the overall manufacturing Purchasing Managers’ Index (PMI) remains in positive territory, registering a score of 51 in March. This indicates continued, albeit modest, expansion in the sector. However, the outlook has deteriorated significantly, with business sentiment declining across all sectors. Smaller businesses, in particular, are expressing greater concern than larger companies, likely due to their limited resources and ability to absorb cost increases.

Vendor delivery times have also lengthened, reaching a four-and-a-half-year high, reflecting the ongoing supply chain disruptions. Despite these challenges, demand in March remained relatively resilient, suggesting that consumers and businesses are still willing to purchase manufactured goods, albeit at a potentially slower pace. Selling prices, however, are rising at the fastest rate since May 2025, and employment levels are declining, indicating that manufacturers are struggling to maintain profitability and staffing levels.

The situation facing UK manufacturers is complex and evolving. The combination of geopolitical instability, rising energy prices, and supply chain disruptions is creating a challenging environment. While the sector remains in expansionary territory, the deteriorating outlook and increasing cost pressures suggest that the coming months will be difficult. The next key indicator to watch will be the April manufacturing PMI, scheduled for release on May 3rd, which will provide a further assessment of the sector’s health and the impact of the ongoing challenges.
