Oil prices have taken a slight breather this week, but it would be a mistake to read too much into the dip. Beneath the surface, the market remains extremely tight, highly reactive, and deeply uncertain about what comes next.
After weeks of sharp gains driven by the escalating conflict involving Iran, crude benchmarks edged lower, with Brent hovering just under $108 per barrel and West Texas Intermediate (WTI) around $94.
The immediate trigger for the pullback was President Trump’s decision to extend a pause on attacks targeting Iran’s energy infrastructure. On paper, that signals a window for de-escalation. In reality, it has done little to calm nerves.
What we are seeing now is a shift in how oil markets are reacting. Prices are no longer just moving on headlines; they are being driven by expectations around how long this conflict could last and how severe it might become. Even with talk of negotiations, traders are clearly not convinced a resolution is close. That lingering doubt is keeping prices elevated.
The scale of the disruption is also hard to ignore. An estimated 11 million barrels per day has been taken out of global supply, a figure that puts this crisis in the same conversation, or even beyond historic shocks like the 1970s oil crises. When supply losses reach that level, the market doesn’t just react it reprices risk entirely.
There are also critical pressure points still in play. The Strait of Hormuz remains a key concern, as does Iran’s Kharg Island, a major oil export hub. Any direct escalation involving either would likely trigger another sharp move upwards. That’s why even small developments such as troop movements, diplomatic proposals and deadlines are being watched so closely.
Looking ahead, the range of possible outcomes is unusually wide. If tensions ease in the coming weeks, prices could fall back relatively quickly, though likely not to pre-conflict levels. But if the situation drags on into the summer, some forecasts suggest oil could climb dramatically higher, even approaching $200 per barrel in a worst-case scenario.
For fuel prices here in the UK, the takeaway is clear. Despite this week’s dip, we are not yet in a downtrend. Wholesale costs remain high, and volatility makes it difficult for retailers to adjust prices with confidence. As a result, motorists are unlikely to see meaningful relief at the pumps in the short term.
In fact, if anything, the current situation reinforces just how exposed fuel prices are to geopolitical risk. Until there is a clear and sustained de-escalation, the market will continue to price in uncertainty and that means continued pressure on both petrol and diesel prices.
Fuel card prices will see their lowest rise this month of 4 pence per litre for next week.

Fuel Market Update 20/03/2026
Oil Prices Slip Slightly - But the Pressure Isn't Going Away
Oil markets ended the week on a softer note, but don’t let that fool you. Beneath the surface, the fundamentals still point to a market under strain and for consumers, especially across the UK, the impact is only just beginning to bite.
At the time of writing, Brent Crude is trading at around $106.71 per barrel, up from roughly $103 at the start of the week. Meanwhile, West Texas Intermediate has slipped back to $93.58 after starting the week above $99. A late dip, yes - but overall, oil is still firmly on track for weekly gains.
The key driver behind this week’s price movement remains ongoing disruption in the Middle East, particularly around the Strait of Hormuz, one of the most critical arteries for global oil supply.
For a third consecutive week, tanker flows and export logistics have been under pressure. Even the suggestion of instability in this region is enough to move markets. The reality, however, is more serious: when supply chains are disrupted at this scale, recovery is rarely quick or straightforward.
Even if safe passage were restored tomorrow, the backlog of delayed shipments, rerouted vessels, and interrupted production would take time - potentially weeks to normalise.
The slight pullback in prices came after a series of statements from global leaders. These included discussions around restoring tanker flows, the possibility of easing sanctions on Iranian oil, and even releasing additional barrels from strategic reserves. All of this helped calm markets - temporarily.
But there’s a clear gap between talk and execution. None of these measures can deliver immediate supply, and traders are well aware of that. For now, the market is reacting to headlines, not barrels.
Complicating matters further is the continued tension in the region. Reports of ongoing Israeli strikes on Iran highlight just how fragile the situation remains. Diplomatic solutions are being discussed, but tangible progress appears limited.
That uncertainty is what keeps the so-called “war premium” baked into oil prices and it’s unlikely to disappear anytime soon.
For UK drivers, the effects are already visible.
And importantly, these increases don’t yet reflect the full extent of wholesale price rises. There is typically a lag before higher oil prices fully feed through to forecourts. That means more pain is on the way.
There is a very real possibility that diesel prices could approach ÂŁ2.00 per litre in the coming weeks if current conditions persist.
In the short term, volatility is almost guaranteed. Prices will likely continue to react sharply to geopolitical headlines - rising on signs of escalation and easing slightly on diplomatic developments.
However, the broader picture suggests:
Even in a best-case scenario, where tensions ease quickly, the recovery in supply chains won’t be immediate.
For businesses, fleet operators, and everyday drivers alike, the message is clear: fuel costs are rising, and the pressure isn’t over yet.
Fuel card prices will rise by a further 10 pence per litre for next week, another unwanted week of double digit rises.
