Oil Back Above $90: Seven Reasons Prices Are Rising Again – And What It Could Mean for Your Heating Bill This Winter

22nd July 2026

For many people in Caithness, the price of oil isn't just something reported on the business pages. It can determine how much it costs to heat a home, fill a tractor, run a fishing boat or transport goods across the Highlands.

With Brent crude oil climbing back above $90 a barrel, many people are asking the same question: why is this happening again?

Oil Price - Brent Crude $90.86 at 7.30pm 21 July 2026

The answer is not one single event. Instead, several developments around the world are combining to make traders nervous about future supplies. Whenever markets become worried that oil could become harder to obtain, prices often rise long before any actual shortage appears.

The Houthis Have Added a New Threat

One of the latest concerns comes from Yemen, where the Houthi movement has reportedly warned that ships calling at Saudi Arabian ports could become potential targets.

Whether these threats develop into widespread attacks remains to be seen. However, shipping companies, insurers and oil traders cannot afford to ignore them.

Even if only a small number of tankers alter their routes, the consequences can include:

higher insurance premiums,
longer shipping journeys,
increased freight costs,
delays in deliveries.

Oil markets dislike uncertainty, and they quickly build these risks into prices.

The Middle East Remains on Edge

The Houthis are only part of a much bigger picture.

Across the Middle East there remain concerns over:

tensions involving Iran,
security around the Persian Gulf,
the safety of oil production facilities,
possible disruption to the Strait of Hormuz.

The Strait of Hormuz is one of the world's most important energy chokepoints. Around one-fifth of global oil consumption passes through this narrow stretch of water.

Even the possibility of disruption is enough to make traders bid prices higher.

OPEC+ Is Still Controlling Supply

Saudi Arabia and its partners in OPEC+ continue to manage oil production carefully.

Instead of producing as much oil as possible, they have generally preferred to keep supplies relatively tight.

From their perspective, lower production often means stronger prices and higher revenues.

For consumers, however, it means there is less spare oil available if another crisis develops.

Russia Continues to Create Uncertainty

Although Russian oil continues to reach world markets, the situation remains complicated.

Sanctions, changing shipping routes, damaged refineries and political tensions all make future supplies harder to predict.

Markets do not need an actual shortage to raise prices.

Sometimes uncertainty alone is enough.

Demand Has Held Up Better Than Expected

Many analysts had expected weaker economic growth this year.

Instead:

the United States has remained relatively resilient,
China has continued importing significant quantities of crude,
aviation demand has stayed strong,
road fuel consumption has been better than forecast.

If demand grows while supplies remain constrained, prices naturally move upwards.

Investors Often Magnify Price Movements

Oil is not bought only by refineries


Large investment funds also buy and sell oil futures.

When investors believe prices are likely to rise, they often buy additional contracts, pushing prices even higher.

This financial activity can accelerate movements that begin for genuine supply-and-demand reasons.

There Is Little Room for Error

Perhaps the biggest issue is that the world no longer enjoys a large cushion of spare production.

If another major disruption occurred—whether from conflict, extreme weather or damage to oil infrastructure—there may not be enough unused production elsewhere to replace it quickly.

That keeps markets nervous.

Why This Matters in Caithness

People living in the far north often feel higher oil prices more than many households elsewhere in Britain.

Unlike towns connected to the gas grid, thousands of rural homes still depend upon heating oil.

Higher crude oil prices can eventually feed through into:

more expensive heating oil deliveries,
higher diesel prices,
increased transport costs,
rising food prices,
higher costs for local businesses.

Fishing vessels, agricultural machinery, haulage firms and many small businesses all depend heavily on diesel fuel.

If transport costs rise, those increases can eventually appear in the price of almost everything we buy.

Could Heating Oil Rise Again?

Unfortunately, the answer is yes.

Wholesale crude oil is only one part of the price paid by households. Refining costs, distribution, exchange rates and local competition also play a part.

However, if Brent crude remains above $90 for an extended period, it becomes increasingly difficult for heating oil prices to remain unchanged.

Households that rely on oil may therefore face another expensive winter unless world tensions ease.

Is This Another Energy Crisis?

Not necessarily.

Today's market is very different from the dramatic price spike following Russia's invasion of Ukraine.

Global oil supplies remain available.

The concern is that several separate risks are occurring simultaneously.

The Houthis are threatening shipping.

The Middle East remains unstable.

OPEC+ continues limiting production.

Russian exports remain uncertain.

Demand has proved stronger than expected.

Taken individually, none of these factors might have pushed oil above $90.

Together, they have been enough to make traders increasingly cautious.

The Bottom Line

The rise in oil prices is a reminder that events thousands of miles away can have a direct impact on household budgets here in Caithness.

Few people can influence conflicts in the Middle East or production decisions made by OPEC.

But everyone can understand why prices move—and prepare accordingly.

If oil remains above $90 throughout the autumn, rural households, businesses and motorists may once again find themselves paying the price for events unfolding far beyond our shores.
