Oil Is Back to Pre-War Levels – Why Isn’t Petrol?

You’d think with oil prices crashing back to where they were before the Iran conflict started, your petrol station would be slashing prices left and right. It’s not happening. And that’s not just frustrating – it’s a textbook reminder of how energy markets really work. Oil itself is a global commodity that moves fast. Petrol at the pump? That’s a different beast entirely. Let’s dig into the mechanics, the lag, and what drivers in the US, UK, and Canada should actually expect in the weeks ahead.

Remember the shock of late February? When tensions erupted on 28 February, Brent crude – the global benchmark – shot from around $80 a barrel to over $120 in a matter of days. The Strait of Hormuz, through which roughly 20% of the world’s oil passes, suddenly became a war zone. Tanker routes were disrupted, insurance premiums for vessels skyrocketed, and a wave of panic buying swept through futures markets. Oil markets were truly rocked. But now, with diplomatic channels reopening and supply flows stabilising, crude has slid all the way back to that pre-conflict $80 handle. So where’s the relief at the pump?

The Great Oil Price Reversal

First, the raw data. Brent crude on 27 February sat at $79.50 per barrel. By 7 March, it had touched $124.60 – a staggering 57% spike in barely a week. Today, as of mid-April, Brent is hovering around $81. That’s essentially a full round-trip. But here’s where it gets messy: the average US regular gasoline price, according to AAA, went from $3.48 per gallon pre-conflict to $4.22 by mid-March, and has only eased to $3.92 now. In the UK, petrol prices went from roughly 142p per litre to a peak of 168p, and now sit around 158p. Canada saw a similar pattern – from C$1.49 per litre to C$1.78, then down to C$1.65. Notice the gap? Oil is back to square one, but petrol is still 12-14% above its pre-war level.

Why? Because crude oil is only part of the petrol price equation. Refining, distribution, taxes, and retail margins all add layers. Think of it like this: crude is the raw flour, but petrol is the finished loaf of bread. When wheat prices crash, bread prices don’t fall instantly – bakeries still have to work through expensive inventory and contractual costs. Same logic applies.

The Lag Factor: Why Petrol Drops Slower Than Oil

This phenomenon has a nickname in the industry: “rocket and feather” – prices go up like a rocket but come down like a feather. Petrol stations buy their fuel on wholesale markets, and those wholesale prices are based on a moving average of recent crude prices. When oil spikes, wholesalers immediately pass on the increase because they’re paying more for new shipments. But when oil drops, those same wholesalers still hold tanks full of expensive petrol bought days or weeks earlier. They don’t cut prices until they’ve sold that inventory and replaced it with cheaper stock.

“The crude oil market is forward-looking, but retail gasoline is backward-looking,” said Denton Cinquegrana, chief oil analyst at OPIS. “The average price you see at the pump today reflects crude prices from about two weeks ago. It takes time for the current lower crude to trickle through.”

On top of that, refining margins – the so-called crack spread – have remained wide. Refineries fired up extra capacity after the spike to meet demand, but some are now throttling back for maintenance. And there’s the seasonal wildcard: summer-blend gasoline. In the US and Canada, refineries are switching to more expensive summer-grade fuel that burns cleaner but costs more to produce. That happens every spring regardless of oil prices. So even with crude back to $80, the pump price has an extra seasonal premium baked in.

Then there’s the dollar. Crude is priced in dollars, and the greenback has weakened slightly in recent weeks, making oil cheaper for holders of other currencies. But the effect on petrol in pounds or Canadian dollars is muted. For UK drivers, the bigger factor is taxes – roughly 53p per litre in fuel duty plus 20% VAT. Those haven’t changed. In Canada, carbon taxes are adding pressure. In the US, federal and state excise taxes vary widely but average around 49 cents per gallon. None of that is going away.

Regional Variations: Who’s Getting Relief and Who Isn’t

The picture is not uniform. Look at the US Gulf Coast, home to the bulk of America’s refining capacity. Houston drivers are already seeing prices dip below $3.30 a gallon – a far cry from the $4.05 peak. That’s because the region has its own refineries and short supply chains. The lag there is shorter. But in the Pacific Northwest or rural parts of Canada, where petrol has to travel farther and competition is thinner, prices are stickier. British Columbia, for instance, still shows prices around C$1.72 per litre, barely down from the peak.

In Europe, the story is complicated by the fact that many refineries shut down during the pandemic and haven’t returned. Europe now imports refined products – diesel especially – from the US and Asia. That adds transport costs and time. The UK, which lost several refineries over the last decade, is particularly exposed. The RAC reports that while wholesale petrol prices in the UK have dropped 12p per litre since early March, the average pump price has only fallen 6p. “There’s a clear disconnect,” said Simon Williams, RAC fuel spokesman. “We’re calling on retailers to be fair and pass on the savings faster.”

The broader market turbulence in Asia – where the Korea Kospi circuit-breaker kicked in three times this week amid tech sector panic – hasn’t directly impacted petrol prices, but it does reveal a risk-averse mood. Investors are spooked by high inflation and interest rates, and that can feed back into commodity futures markets, adding volatility. But the key takeaway for the average driver is regional: if you live near a refinery hub, you’ll see relief weeks earlier than someone in a remote area.

The Bigger Picture: What This Means for Central Banks

The return of oil to pre-war levels is actually a double-edged sword. On one hand, it should ease headline inflation numbers – energy costs were a major driver of the CPI spikes in March. The US Bureau of Economic Analysis data already shows a slight cooling in gasoline prices in the April consumer spending report. On the other hand, core inflation (excluding food and energy) remains stubbornly high. Central bankers in Washington, London, and Ottawa are all watching this carefully.

“A sustained drop in oil is good news for central banks – it takes the pressure off,” said Ludovic Subran, chief economist at Allianz. “But they won’t declare victory based on one commodity. Service inflation and wage growth still need to moderate.”

Interestingly, the rapid price reversal also exposes the limits of geopolitical risk premiums. The market priced in a worst-case scenario – a full Strait of Hormuz closure – that didn’t fully materialise. When that scenario faded, oil crashed. But that’s a double-edged sword: it means the next crisis – whether it’s another attack, an OPEC+ surprise output cut, or a hurricane slamming the Gulf Coast – could re-ignite the premium just as fast.

For now, drivers should see a slow but steady decline in petrol prices over the next three to four weeks. If Brent stays around $80, expect US national average gasoline to reach about $3.60 by mid-May. UK prices could dip to 148p per litre. Canada maybe C$1.55. But don’t expect pre-war levels exactly – refinery margins and summer blends will keep floors higher. And if the geopolitical landscape shifts again? All bets are off.

Look, the oil market has spoken: the Iran war premium is gone. But the petrol pump is a slow listener. It’ll catch up eventually – just not on your timetable.
