War, Hormuz and Supply Chains: What Businesses Can Actually Do
When conflict reaches a vital shipping corridor, the consequences travel much further than the ships themselves. Energy, freight, manufacturing and customer delivery all feel the pressure. What should a business do first?
Wars have human consequences first and foremost. They also expose how dependent everyday business operations are on safe transport routes, reliable suppliers and affordable energy. For European manufacturers, importers and logistics providers, the question is not whether every geopolitical risk can be predicted. It is whether the business knows where it is exposed and what to do when conditions change.
The conflict involving the United States, Israel and Iran during 2026 has put the Strait of Hormuz at the centre of that question. This is an operational perspective, not a political commentary or a forecast of military events.
One narrow passage. Consequences across entire supply chains.
Military escalation involving the United States, Israel and Iran began on 28 February 2026. Shipping through the Strait of Hormuz has since faced significant disruption, including attacks on commercial vessels and changing security conditions. The International Maritime Organization warned in August of the danger to seafarers and freedom of navigation.
As of 30 October 2026, the situation remains unsettled. Reuters reported a mine attack on a tanker near the strait on 29 October; responsibility was not established in that report. Conditions may change quickly, so routing and security decisions must use current specialist advice rather than an article like this.
The impact rarely stops at the port.
A shock in a maritime corridor can move through purchasing, production and distribution in several steps. The diagram below is a simplified business model, not a live traffic map.
Maritime riskRoutes, vessel access, insurance
Cost pressureEnergy, fuel, freight, materials
OperationsSupplier lead times, capacity, inventory
Customer serviceAvailability, delivery dates, margins
Fuel and power costs
Road transport, ocean freight, heating, production and energy-intensive suppliers can all face price pressure, often with a delay.
Capacity and reliability
Alternative routing does not automatically create capacity. Longer journeys can affect vessel and container availability, schedules and working capital.
Material availability
Chemicals, plastics, fertilisers and other energy-linked inputs may be exposed indirectly, even where the first-tier supplier is European.
Stop treating freight cost as the only risk.
A lower purchase price can become expensive when a late component stops production. An alternative carrier may charge more but protect the delivery date. Equally, holding extra inventory everywhere can drain cash without solving the true bottleneck.
| Business question | Check in practice | Useful management signal |
|---|---|---|
| Where are we exposed? | Map critical products, supplier locations, ports, routes and energy-intensive operations. Include indirect dependencies. | Percentage of critical items with a documented second option |
| Can we still deliver? | Compare promised delivery dates with realistic supplier and transport lead times. | Orders at risk, on-time-in-full (OTIF), delivery exceptions |
| What will it really cost? | Model transport, insurance, fuel surcharges, storage, inventory and potential downtime together. | Landed cost by product or lane, margin at risk |
| How much buffer is justified? | Segment products by criticality and replenishment uncertainty instead of raising stock across the board. | Days of cover for critical materials, working capital exposure |
| Who decides when conditions change? | Agree triggers, owners and approval limits for alternate sourcing, expedited freight and customer communication. | Time from disruption alert to action |
Five actions that can start this week.
Identify the products you cannot afford to lose
List the materials, components and shipments that would stop production or cause serious customer disruption. Prioritise these, rather than trying to map every item at once.
Speak to suppliers and carriers about actual constraints
Ask which routes, subcontractors, ports or inputs are affected. Request realistic lead-time ranges and agreed escalation contacts, not just general assurances.
Prepare alternatives before paying for them
Assess replacement suppliers, multimodal routes, substitute materials and local capacity. Check qualification, compliance, capacity, cost and lead time before assuming an option is usable.
Run three simple operating scenarios
Test a short disruption, an extended disruption and a sharp cost increase. For each, estimate customer impact, cash requirements, operational limits and the decision needed.
Set a short decision rhythm
Bring procurement, operations, logistics, finance and sales together around the same exceptions. Agree what changes a production plan, a customer promise or a purchasing decision.
One delayed component. An entire production plan at risk.
Consider a mid-sized European equipment manufacturer that buys a specialist component through a distributor. The company has no direct purchases from Iran or the Gulf. Yet the component’s upstream producer is energy-intensive, and its supply route involves several international transport legs.
As lead times become uncertain, the manufacturer faces three choices: keep the existing plan and risk a shutdown; pay for urgent transport; or resequence production around available parts. None is automatically right.
A practical response combines supplier confirmation, stock visibility, product priorities and a costed decision. The goal is not to build an elaborate geopolitical forecasting department. It is to know which decisions protect customers and which costs are justified.
Illustrative scenario, not a claim about a Merlyn client or a measured financial result.
Resilience is not the same as having more stock.
The original 2022 article, written in the context of Russia’s invasion of Ukraine, already highlighted energy, freight capacity and supply chain resilience. Those themes still matter. The 2026 Hormuz crisis illustrates why resilience must become an operational capability rather than a one-off emergency project.
That capability starts with visibility into critical dependencies, sensible alternatives, reliable information and clear ownership of decisions. Technology can support it, but dashboards do not replace supplier relationships, practical planning and management judgement.
For smaller businesses, the right approach is proportionate: focus on a handful of critical flows, monitor the relevant signals and keep options ready. Trying to make every supply route completely risk-free would be neither realistic nor affordable.
