University of Salford Expert Warns Trump’s 15% U.S. Tariff Could Send UK Supply Chains into Turmoil

Dr Jonathan Owens, Senior Lecturer in Operations Management and global supply chain expert at the University of Salford, said: Potential shockwaves from Donald Trump’s global 15% U.S. tariff could disrupt UK supply chains overnight

If implemented, a 15% tariff policy under Donald Trump could send immediate shockwaves through UK supply chains, despite the measures being imposed by the United States. The UK is tightly woven into global trade networks, and many British firms either export directly to the U.S. or supply critical components that feed into American markets. A sudden cost barrier of this scale would not be contained within U.S. borders and could ripple quickly across the Atlantic.

In the short term, higher U.S. import costs would likely suppress demand for UK goods, particularly in strategically vital sectors such as automotive manufacturing, aerospace, machinery, and pharmaceuticals. British suppliers embedded in transatlantic production lines could face abrupt order cancellations, forcing production cuts and leaving warehouses with unsold inventory. For smaller firms operating on thin margins, such disruption could quickly escalate into a cash-flow crisis.

The indirect fallout could be equally destabilising. Countries hit by falling U.S. demand may flood European markets with surplus goods, intensifying price competition and squeezing UK manufacturers. At the same time, currency volatility could surge, driving up hedging costs and injecting further unpredictability into procurement and pricing strategies.

Logistics networks would not escape unscathed, as shipping routes could be rapidly reconfigured as firms scramble to avoid tariff exposure. This could lead to port congestion, delivery delays, and rising freight costs.

While the long-term consequences would depend on political negotiations, the immediate impact would be clear: heightened uncertainty, mounting cost pressures, and a period of acute supply chain turbulence as UK businesses fight to remain resilient.

However, this could ultimately prove to be little more than a burst of political theatre, generating headlines rather than lasting economic damage. If the policy were short-lived, disruption to UK supply chains might be sharp but brief.
