The Hormuz crisis is creating winners in Australia — while motorists and businesses pay the price

Australia has so far managed to maintain its supplies of imported refined fuel despite the Strait of Hormuz crisis. But new figures from Ampol reveal another side of the energy shock: extraordinary refining profits are being generated as Asia competes for increasingly expensive petrol, diesel and aviation fuel.

The Strait of Hormuz is thousands of kilometres from Australia.

Its consequences are now appearing in Australian company accounts.

Ampol has reported an underlying net profit after tax of $857.2 million for the first half of 2026, almost five times the comparable result a year earlier.

At its Lytton refinery in Brisbane, refining margins more than tripled to US$28.26 a barrel.

The company's fuel and infrastructure earnings increased nine-fold.

Its interim dividend jumped from 40 cents to $1.85 a share.

Ampol shares subsequently reached their highest level in more than two years.

This is not simply an Ampol success story.

It tells us something much bigger about what the Iran war and disruption around the Strait of Hormuz are doing to the energy economy.

There are winners.

There are losers.

And Australia is increasingly experiencing both.

Oil and fuel are not the same thing

Much of the international discussion surrounding Hormuz has concentrated on crude oil.

How many tankers are getting through?

How many barrels are moving?

How much oil is available?

Those are important questions.

But they are no longer sufficient.

The more immediate problem developing across Asia is the availability of refined petroleum products.

Petrol.

Diesel.

Jet fuel.

These are the products consumers and businesses actually use.

Reuters analysis published on August 24 shows imports of light and middle distillates into Asia during August are running about 21 per cent below pre-conflict averages.

That is an enormous reduction in a region containing some of the world's largest economies and fuel consumers.

Australia has avoided the worst of the shortage

There is an important Australian distinction.

Some less wealthy Asian countries have experienced significant reductions in refined-fuel imports.

Australia has so far maintained relatively stable import volumes.

That sounds reassuring.

It is.

But there is another side to the equation.

Australia is paying considerably more for those supplies.

In effect, our purchasing power provides protection.

Australia can compete for scarce fuel on international markets.

But avoiding a physical shortage does not mean avoiding the economic consequences of the shortage.

We can obtain the fuel.

We simply have to pay the market price necessary to secure it.

Singapore tells the story

One number demonstrates the extraordinary conditions developing in the refining market.

Singapore gasoil refining margins reached around US$71.29 a barrel in August.

That is an extraordinary margin.

Gasoil is closely associated with diesel and middle-distillate markets, making it particularly important to economies dependent upon trucking, agriculture, mining and heavy industry.

Australia qualifies on every count.

The problem therefore cannot be understood simply by looking at the international price of crude oil.

A barrel of crude is not a litre of diesel.

Crude must be transported.

Refined.

Converted into usable products.

Those products must then be transported to markets where they are required.

At each stage, scarcity can develop.

Right now, the refinery stage has become particularly valuable.

That helps explain Ampol's extraordinary result

Ampol owns the Lytton refinery in Brisbane.

In ordinary circumstances, refining can be a difficult business.

Margins fluctuate.

Refineries are enormously expensive to operate and maintain.

Competition from large Asian refining complexes can be intense.

The economics change dramatically when refined petroleum products become scarce.

Ampol's Lytton refining margin increased from US$8.47 a barrel to US$28.26.

The consequences flowed directly into earnings.

Underlying first-half profit rose to $857.2 million, compared with $174.2 million previously.

Reuters described the result as almost double Ampol's previous first-half record set in 2022.

The Hormuz crisis has therefore produced something quite remarkable.

An international supply shock is simultaneously increasing the cost of energy while making strategically located refining capacity much more valuable.

This is not about blaming Ampol

That distinction is important.

Ampol did not create the Iran war.

It did not close Hormuz.

It did not create Asia's shortage of refined fuels.

And it does not independently determine international petroleum prices.

The company owns refining infrastructure at precisely the moment when refining capacity has become unusually valuable.

Businesses exist to make profits.

Shareholders expect them to do so.

The Ampol result is important not because extraordinary profits are inherently improper.

It is important because those profits provide a window into what is happening throughout the regional fuel market.

When refinery margins rise dramatically, someone ultimately pays those margins.

The refinery problem is more complicated than it looks

There is another misconception worth addressing.

If the world can find replacement crude oil outside the Persian Gulf, why can't refineries simply process that instead?

Because crude oils are not identical.

Different crude grades contain different characteristics.

Refineries themselves are designed and configured around particular combinations of feedstocks and desired products.

Middle Eastern medium crude grades are particularly useful for producing important middle distillates such as diesel and aviation fuel.

Replacing those barrels with a different type of crude does not necessarily produce exactly the same quantity or mix of finished products.

That is one reason the current debate about how many barrels of crude are passing through Hormuz can obscure the bigger problem.

The world can have crude oil available while simultaneously experiencing a shortage of particular refined fuels.

Watch what comes out of the refineries

Our recent Hormuz coverage has emphasised one useful principle:

Watch the ships.

That remains important.

But we can now add another.

Watch what comes out of the refineries.

The latest ship-tracking figures remain extraordinary.

Only four commodity vessels were recorded crossing Hormuz on Sunday, following 13 on Saturday and 16 on Friday.

Over the latest measured week, traffic remained approximately 90 per cent below pre-conflict levels.

Ship-tracking figures are imperfect because vessels operating without public transponders may not appear in the data.

Even allowing for that limitation, this is nothing resembling normal commercial traffic through one of the world's most important energy corridors.

Twenty-three vessel incidents

There is another reason commercial operators remain cautious.

Since July 6, Britain's UK Maritime Trade Operations has reported 23 incidents involving projectile strikes that caused damage to vessels, according to Reuters.

That changes the calculation for everyone involved.

Ship owner.

Charterer.

Cargo owner.

Insurer.

Crew.

Bank.

Customer.

A vessel may technically be capable of passing through Hormuz.

That does not mean everyone involved in sending it there believes doing so is commercially sensible.

Risk acquires a price.

Eventually somebody pays it.

The Australian motorist is near the end of the chain

Consider how the process works.

Disruption reduces normal energy flows.

Buyers seek alternative supplies.

Shipping routes become more complicated.

Insurance risk increases.

Refineries compete for suitable crude.

Refined products become scarce.

Refining margins increase.

Importers compete for available petrol and diesel.

Australia pays what is necessary to secure supply.

Eventually the fuel reaches the service station.

The motorist sees only the final number on the price board.

Behind that number can be an extraordinary international supply chain.

But motorists are only part of the story

Diesel is one of the fundamental inputs of the Australian economy.

It powers trucks moving goods between cities.

It powers agricultural machinery.

It powers mining equipment.

It powers construction machinery.

It powers commercial vessels.

It is essential throughout regional Australia.

Higher diesel costs therefore spread.

A trucking company facing higher fuel costs must either absorb them or eventually recover them from customers.

A farmer pays more to operate machinery.

A contractor pays more to run equipment.

A supermarket's suppliers pay more to transport goods.

Mining costs increase.

Regional businesses face higher freight bills.

The consequences become embedded throughout the economy.

Aviation is exposed too

Jet fuel deserves equal attention.

Australia is geographically isolated.

Aviation is therefore not simply a discretionary luxury.

It connects Australian cities.

It connects regional communities.

It carries business travellers.

It brings international tourists.

It moves freight.

And it connects Australia with the rest of the world.

A prolonged shortage of middle distillates can therefore create pressure extending well beyond the petrol station.

Airlines operate in an intensely competitive industry where fuel represents a major cost.

Higher aviation-fuel costs ultimately have to be absorbed somewhere.

Then inflation enters the story

This is where Hormuz becomes relevant to Australian monetary policy.

Higher fuel costs can spread throughout an economy.

Transport.

Food.

Construction.

Travel.

Mining.

Agriculture.

Manufacturing.

Delivery services.

The Reserve Bank can respond to inflation.

But it cannot solve the underlying problem.

Higher Australian interest rates will not produce more diesel in Singapore.

They will not make tankers sail through Hormuz.

They will not reduce war-risk insurance.

They will not alter the chemistry of crude oil.

They will not end the Iran conflict.

That is the difficulty created by imported inflation.

Australia can suppress demand.

It cannot easily remove the external supply shock.

Australia's remaining refining capacity suddenly looks different

There is another strategic lesson buried inside Ampol's result.

For years Australia has debated the future of domestic refining.

Large Australian refineries have closed as the economics increasingly favoured enormous overseas facilities.

Australia consequently became increasingly dependent upon imported refined petroleum products.

In peaceful, highly efficient international markets, that can make economic sense.

The Hormuz crisis demonstrates the other side of the calculation.

Domestic refining capacity has strategic value.

It does not make Australia energy independent.

A refinery still needs crude feedstock.

But the ability to turn crude into usable fuels inside Australia provides flexibility.

The extraordinary profitability of Lytton during the present crisis demonstrates just how valuable refining capacity can become when regional product markets tighten.

Refiners elsewhere are benefiting too

Ampol is not alone.

The Iran war has created unusually favourable conditions for refiners internationally.

China's Sinopec has just reported first-half profit growth of 19.3 per cent, despite falling domestic demand and disruption associated with the conflict.

Its refining margin improved 44.1 per cent and operating profit from refining increased dramatically.

Earlier Reuters analysis described the current environment as a new "golden era" for oil refining, although one that is unlikely to last indefinitely.

That reinforces the broader point.

The beneficiaries are not creating the shortage.

They own something that becomes extremely valuable during one:

the ability to manufacture scarce fuel.

There are winners and losers in every energy shock

Oil shocks are often discussed as though everybody loses.

They don't.

Oil producers can benefit from higher crude prices.

Refiners can benefit from higher refining margins.

Tanker operators can benefit from higher freight rates.

Some commodity traders can benefit from volatility.

Alternative suppliers can acquire new customers.

Governments collecting petroleum-related revenue can sometimes benefit.

Meanwhile consumers, fuel-intensive businesses and fuel-importing countries carry much of the cost.

That does not make the system unfair by definition.

It demonstrates how markets allocate scarcity.

Higher prices encourage additional supply and discourage consumption.

But understanding who benefits helps explain what is actually happening.

Australia's ability to pay is an advantage

There is an uncomfortable international dimension.

Australia is a wealthy country.

If refined fuel becomes scarce, Australian importers can compete aggressively for available cargoes.

Poorer countries have less capacity to do so.

That means a regional shortage may not appear in Australia as empty service stations.

It may appear as higher prices.

For another country it can appear as less fuel actually arriving.

That distinction matters.

Australians understandably dislike expensive petrol and diesel.

But paying more for available fuel is a very different problem from being unable to obtain enough fuel at all.

What happens next?

There are now several indicators worth following.

Hormuz vessel traffic remains one.

The return of VLCC crude tankers matters.

The return of LNG carriers matters.

Insurance premiums matter.

But for Australia, another group of indicators has become equally important.

Asian diesel supply.

Jet-fuel supply.

Singapore refining margins.

Australian refined-product imports.

And the performance of Australia's remaining refineries.

If shipping normalises and suitable Middle Eastern crude returns to Asian refineries in sufficient quantities, refining margins should eventually retreat.

If Hormuz remains severely constrained, the refined-product shortage could persist even if headline crude prices appear comparatively stable.

That is the important distinction.

The Times View

Australia is beginning to discover that an oil crisis and a fuel crisis are not necessarily the same thing.

There may be millions of barrels of crude available somewhere in the world.

That does not mean the right crude is at the right refinery producing the right fuel in the right quantity for the Australian market.

The extraordinary Ampol result provides tangible evidence of that reality.

A refining margin that more than triples does not occur in isolation.

It tells us that refining capacity has suddenly become enormously valuable.

Australia has so far been fortunate.

Our wealth and sophisticated supply chains mean we have continued obtaining refined petroleum products while some other Asian countries have suffered substantial reductions.

But we are paying for that security.

The cost will not necessarily arrive as an invoice marked "Strait of Hormuz."

It can arrive in the price of diesel.

The cost of freight.

An airline ticket.

A farmer's fuel bill.

A construction quote.

A supermarket product.

And eventually, potentially, in Australia's inflation figures.

The Hormuz crisis is producing winners.

Ampol's extraordinary result shows us where some of them are.

For Australian households and businesses, however, there is another lesson.

Avoiding a fuel shortage is not the same thing as avoiding its cost.

We have been watching the ships.

Now we should also watch what comes out of the refineries.
