UK factory output has reached a 21-month high, driven by strategic stockpiling ahead of anticipated supply chain disruptions and price rises linked to the Iran conflict. The S&P Global UK manufacturing PMI recorded 52.5 in June, easing from 53.9 in May yet marking an eighth consecutive month of expansion. For Ireland’s manufacturers, interwoven with UK and European supply chains, the data carry immediate significance.

The PMI results underline that global manufacturers are navigating three converging forces: geopolitical disruption driving defensive stockpiling, energy cost volatility compressing margins, and fading new order growth creating medium-term uncertainty. Ireland, whose manufacturing sector generates €197.25 billion in goods exports annually and employs over 220,000 people, faces these same pressures, yet its advanced manufacturing capabilities position it to convert disruption into competitive advantage.

The output surge reflects firms acting decisively to protect operations. Rob Dobson, director at S&P Global Market Intelligence, attributed the jump to manufacturers seeking to safeguard against supply chain disruptions and anticipated price rises, with factory output expanding at its fastest rate since September 2024. In Ireland, where the domestic PMI stood at 54.9 in June, outperforming the UK’s 52.5, manufacturers are demonstrating comparable resilience.

The underlying pressures are real and persistent. Energy costs have risen sharply following the US-Israel conflict with Iran and the effective closure of the Strait of Hormuz, with manufacturers contending with freight shortages, port disruptions and customs delays. The UK exports £56.4 billion (approximately €67 billion) worth of goods and services to Ireland annually, making supply chain disruption a direct operational concern for Irish manufacturers.

Confidence data adds nuance to the picture. S&P Global’s Dobson noted that manufacturers’ optimism remains tepid, with concerns over geopolitical tensions and uncertain government policy weighing on the outlook. Yet recent easing in energy prices helped cool input cost inflation in June. Bank of Ireland’s 2026 manufacturing outlook finds that Irish firms are entering this environment with strong fundamentals and pragmatic focus on costs and margins.

Irish manufacturing leaders should treat this moment as a catalyst for decisive action across three priorities. First, embed lean manufacturing practices to sharpen operational efficiency and reduce input cost exposure. Second, accelerate supply chain diversification by nearshoring critical inputs and deploying digital visibility tools to anticipate logistics disruptions. Third, strengthen forward-purchasing frameworks to protect against future energy price spikes and freight capacity constraints.

The June PMI data are a signal worth heeding. Global manufacturing is proving its resilience in the face of geopolitical shock, but the firms that will sustain manufacturing excellence are those that move from reactive stockpiling to proactive structural planning. For Ireland’s world-class pharmaceutical, medical technology, and food production sectors, the conditions are ripe to lead that transition and consolidate durable long-term competitive advantage.
