What It Means for Businesses and Households
A global oil supply disruption never stays neatly contained within energy markets and it certainly won’t this time.
In our view, the pattern is well understood but often underestimated. A disruption starts with constrained supply and quickly feeds through into petrol and diesel. From there, transport costs rise, gas markets tighten, electricity prices follow, and household energy bills increase. The final step is the one that tends to catch organisations out: disposable income falls, and demand weakens across multiple sectors.
In the worst case, employees increase working from home due to long queues at petrol stations, and central activities such as schools and social care visits are affected by staff shortages.
As we look into the future, food costs increase dramatically as crops are either not planted due to a lack of fuel and fertiliser, or if they are planted, yields are down.
If this current scenario develops as expected, the scale and speed of that chain reaction could be more significant than many organisations are planning for.
What This Means in Practice
Geopolitical pressure on key oil routes, combined with tight supply conditions, is increasing the likelihood of disruption. Emergency release of strategic fuel reserves softened that initial impact, however, as the Straits of Hormuz remain closed, those reserves will run out and the shock to the global markets will be more pronounced.
Even once reopened, fuel will take time to reach refineries and then the forecourts. The damage to oilfields in the Middle East region will take months to repair. So whichever way you look at it, there is no quick fix to this issue.
For UK organisations, we think this goes well beyond a simple pricing issue. Energy sits at the centre of how goods are produced, transported, and consumed. When it moves, everything else moves with it.
The key question, in our view, is no longer whether prices rise – it’s how those increases interact, and which organisations are most exposed when they do.
Operational impact
From our perspective, the immediate impact is operational. Fuel availability and cost directly affect logistics, distribution, and workforce mobility. Rural areas and any business dependent on transport are likely to feel this first.
Financial impact
What stands out to us is the potential for simultaneous cost pressure. Organisations could be dealing with:
- Electricity increases of ~35–40%
- Heating oil increases of ~30–35%
- Transport fuel increases of ~25%+
Individually, these may be manageable. However, on top of the other cost of living crisis pressures, together they create a very different level of strain, particularly for businesses operating on tight margins.
If those businesses start to fail, what does this mean on supply chains? How smoothly can your business change supplier? In the age of “just in time logistics” who long can you survive the impact of this type of supply chain disruption?
Strategic impact
We would expect to see more difficult strategic decisions emerging quickly — delaying investment, rethinking supply chains, or accelerating moves toward energy efficiency.
On the macro side, can a business hedge its fuel costs in the same way that an airline does? If the storage is possible, can it buy bulk stock now?
Reputational impact
There is also a softer but important impact. Passing costs on to customers is not always straightforward, particularly in sectors where affordability is already stretched. That creates a reputational balancing act.
Who is most Vulnerable?
In our experience, the organisations most exposed tend to share a few common characteristics.
- High energy intensity. Industries like metals manufacturing, glass, ceramics, and food processing often have continuous operations that simply can’t be scaled down without stopping production altogether.
- Fuel-dependent logistics. Haulage, agriculture, fisheries, and construction all rely heavily on diesel. Even relatively small price increases can erode margins quickly.
- Fixed or constrained revenue models. Care providers, public sector contractors, and SMEs tied into long-term pricing agreements often have limited ability to pass on rising costs.
It’s the combination of these factors, rather than any single one, that tends to create the greatest vulnerability.
The Compound Effect (Worst Case Scenario)
Where we think the real risk sits is in the compound effect.
A rural business, for example, could be dealing with:
- A 33% increase in heating oil
- A 37% increase in electricity
- A further 10–15% increase in transport fuel
At the same time, their customers are likely facing higher food prices, rising household energy bills, and less disposable income.
This is where the second-order effects start to bite. As costs rise at household level, spending behaviour changes. People travel less, cut back on discretionary purchases, and eat out less often.
That has a direct impact on sectors like hospitality, tourism, and retail — even if those businesses are not particularly energy-intensive themselves.
This is the point where many organisations are caught off guard.
What Good Looks Like
From our perspective, the organisations that navigate this well tend to do a few things differently:
- They model compound scenarios, rather than looking at each cost increase in isolation.
- They take the time to identify critical dependencies; the parts of the business that simply cannot function under energy or fuel constraints.
- They will stress-test their margins, properly understanding how much pressure they can absorb.
- They will actively engage with their supply chain, rather than assuming resilience.
- And importantly, they make sure their operational plans and financial assumptions are aligned – something that is often overlooked.
Leadership Perspective
Situations like this tend to expose how organisations make decisions under pressure. In our experience, the challenge is balancing immediate cost control with longer-term resilience. Reacting too aggressively can create new risks; reacting too slowly can leave organisations exposed.
The leaders who perform best are usually those who recognise that this type of disruption is not temporary but part of a broader shift toward a more volatile operating environment, and that developing frameworks to horizon-scan and implement mitigations early is a business-critical activity.
Conclusion
We don’t see energy supply shocks as isolated events anymore. They act as triggers for wider disruption, affecting both cost structures and customer behaviour.
Organisations that plan for combined, system-wide impacts are far better positioned to respond. Those who treat risks individually often find themselves reacting too late.
What Next?
While much of the discussion around fuel disruption focuses on pricing and operational pressures, there is another dimension organisations cannot afford to overlook: security and behavioural risk. In Part 2, UK Energy Supply Shock Series next week, we explore how fuel shortages can rapidly evolve into wider resilience and protective security challenges for UK businesses.
