The War That Changed the Map of Energy

Iran, the Strait of Hormuz and the Future of Energy Transfer in the Global Economy

Wars do not only change borders, governments and headlines. They change assumptions. And the war involving Iran has forced the global energy system to question one of its oldest assumptions: that the enormous flow of oil and gas through the Persian Gulf can be treated as a permanent feature of the world economy.

I have spent much of my professional life around energy, shipping and international trade. What strikes me about the present crisis is not simply the disruption itself. It is what the disruption teaches governments, traders, shipowners and energy companies about the years ahead.

The lesson is straightforward: energy security is also transport security. A barrel of oil sitting safely in a producer's terminal is not the same thing as a barrel that can reach a refinery. LNG in a liquefaction plant is not the same thing as LNG delivered to an Asian buyer. The real energy system is the chain connecting production, storage, ports, ships, pipelines, insurance, finance and final consumers.

The Strait of Hormuz is more than a chokepoint

For decades, the Strait of Hormuz has been treated as one of the great fixed points of the global energy map. It is not simply a line on a chart. It is a commercial system through which producers, shipowners, charterers, traders, banks, insurers and governments have built an enormous amount of business.

That system works when everyone believes that ships will move. Once that assumption becomes uncertain, the economics change very quickly.

It is possible for physical exports to continue while the commercial system is already under severe stress. Cargoes may still move, but ships become harder to source, voyages become longer, insurance becomes more expensive, charterers become more cautious and traders begin to pay for optionality.

The hidden price of the war is freight

This is the part of the crisis that I believe deserves much more attention. The price of energy is visible. The price of moving energy is often hidden inside the delivered cost.

In September, Reuters reported that VLCC rates from the Gulf of Oman to China reached around Worldscale 450, equivalent to roughly $11.50 per barrel—the highest level since the route's Worldscale rate was introduced earlier in 2026.

That is not a theoretical number. It changes the economics of a cargo. A producer can reduce the selling price and still leave the buyer paying more because the freight component has exploded.

Then came another striking signal. On October 4, Reuters reported that Saudi Arabia cut its November Arab Light official selling price to Asia by $3 per barrel, taking the discount to $5 below the Oman/Dubai average. The report linked the decision to elevated freight costs and regional disruption.

In other words, freight is beginning to influence the commercial price of the commodity itself.

When the ship becomes the scarce commodity

In a crisis, people naturally look first at the commodity. I look at the vessel.

If a tanker owner believes that a route has become materially more dangerous, the owner has several choices: demand a higher rate, refuse the voyage, wait, reposition the vessel, change the loading point or seek another employment opportunity. None of these decisions happens in isolation.

Once enough owners make similar decisions, the effective supply of ships falls even if the physical number of tankers in the world has not changed.

This is why freight can move so violently. The market is not simply pricing steel and fuel. It is pricing availability, time, security, insurance and uncertainty.

LNG shows the same problem — but with even longer consequences

Oil has alternatives in the sense that cargoes can sometimes be redirected, stored or sourced from another producer. LNG is more constrained by liquefaction capacity, shipping routes, receiving terminals and the availability of suitable vessels.

The International Energy Agency's Q2 2026 Gas Market Report described the effective closure of Hormuz in March as a major shock to global gas markets. During the initial disruption, Atlantic LNG spot freight jumped by $116,500 per day to $278,250/day, while the Pacific benchmark rose by $108,750 to $207,500/day. The IEA said longer voyages, replacement cargoes and tighter effective vessel availability drove the extraordinary move.

The significance goes beyond a few weeks of high freight. If Asian buyers replace Middle Eastern LNG with Atlantic cargoes, the world has not simply lost a cargo—it has changed the voyage pattern. More miles are travelled. More ships are tied up for longer periods. Tonne-mile demand rises. And suddenly the same LNG fleet is doing less work per month.

That is one of the most important concepts for understanding the future of energy shipping: the geography of the cargo matters as much as the volume of the cargo.

Physical exports can recover before confidence does

One of the most interesting developments now is that physical flows have not simply collapsed. Reuters reported on October 5 that Middle Eastern crude exports exceeded pre-war levels on several days in late September, reaching between 19.5 million and 22.5 million barrels per day. The seven-day average was around 18.5 million barrels per day on October 1, compared with roughly 18 million before the war.

That sounds reassuring until you look at the other side of the equation. Reuters also reported that at least seven recent vessel incidents had been recorded around the Strait of Hormuz and that maritime authorities were reporting daily attacks in the region from October 2.

This tells us something important: volume and confidence are not the same thing.

The market can move cargoes while simultaneously becoming less willing to rely on the same route tomorrow.

What changes for the Persian Gulf?

I do not believe the world is going to abandon the Persian Gulf. The reserves, production infrastructure, refineries, export terminals and established commercial relationships are simply too important.

But I do believe the region will be judged differently.

For decades, efficiency often meant concentration: the largest fields, the biggest terminals, the most efficient shipping routes and enormous volumes moving through a small number of strategic corridors.

The new priority is likely to be redundancy.

That means more storage. More pipeline capacity. More alternative export terminals. More refinery flexibility. More strategic inventories. More interconnections between electricity systems. More LNG diversity. More investment in ports that can provide alternatives when one route becomes unavailable.

Places such as Fujairah become strategically important in this environment because geography itself becomes an asset. A port outside the Strait can provide a degree of flexibility that a terminal dependent entirely on passage through the Strait cannot.

Iran faces a difficult strategic paradox

Iran understands the strategic value of its geography better than almost anyone. Hormuz is one of the country's most powerful forms of leverage because so much of the world's energy trade passes nearby.

But there is a paradox.

The more frequently geography is used as a weapon, the stronger the incentive for customers and competitors to build around that geography.

Buyers will diversify suppliers. Producers will invest in alternative routes. Governments will build storage. Shipowners will demand higher risk premiums. Traders will keep optional cargoes. Energy companies will spend money on infrastructure whose purpose is not maximum efficiency, but resilience.

None of this makes Iran irrelevant. But it can gradually reduce the strategic value of being unavoidable.

The future may be diversification, not simply decarbonisation

There is a tendency to describe the future of energy as a simple transition: oil, then gas, then renewables.

I think reality is more complicated.

The war has reminded governments that energy policy is also foreign policy, industrial policy and transport policy. A country may build enormous renewable capacity and still need gas for flexibility. It may import LNG while building nuclear power. It may buy oil while electrifying transport. It may develop hydrogen while expanding conventional infrastructure.

The future energy system is therefore likely to be a portfolio rather than a single replacement technology.

For shipping, this is especially important. The tanker business will not disappear because the energy mix changes. It will change because the routes, cargoes, distances and risk structures change.

What happens to shipping from here?

I expect the industry to become more focused on route optionality. Charterers will think harder about alternative loading points. Shipowners will price geopolitical exposure more explicitly. Insurance clauses will receive greater attention. Banks and financiers will look more carefully at the physical route behind a cash-flow model.

We are also likely to see more investment in ships and infrastructure designed for flexibility. A vessel that can move between regions and cargoes can be more valuable in a fragmented world than a vessel optimised for one narrow trade.

And freight markets will remain part of the energy story. When a war adds thousands of miles to a voyage, the world needs more ships to move the same amount of energy. That is a fundamental shipping equation, and it does not disappear because the commodity price is falling.

The political map will change with the energy map

The consequences will extend beyond shipping.

Europe will continue to value supply diversity. Asia will continue to look for flexible LNG and crude sources. Gulf producers will invest more heavily in downstream industries and alternative export infrastructure. India and China will continue to balance long-term supply relationships against price and geopolitical risk. The United States, Australia and other Atlantic and Pacific suppliers will gain strategic importance when buyers need alternatives.

In the Persian Gulf itself, competition may increasingly be about who can offer the most reliable platform for energy, finance, storage, logistics and trade.

That is a very different competition from simply producing the cheapest barrel.

What I believe the war has changed

I think the most lasting change will be psychological.

Before the war, many commercial models treated geopolitical disruption as a low-probability event. Today, a boardroom discussion about an energy project is more likely to include a question that would once have seemed almost extreme: What happens if this route is unavailable for six months?

That question changes investment decisions.

It changes the value of storage. It changes the value of a second pipeline. It changes the value of a port outside a chokepoint. It changes the value of a flexible LNG contract. It changes the value of a tanker that can reposition quickly.

Most importantly, it changes the meaning of reliability.

Conclusion

I don't believe the world will abandon the Persian Gulf.
Nor do I believe oil and gas are suddenly disappearing.

What is changing is the way governments and companies think about risk.

The customer will demand flexibility.
The shipowner will demand security.
The trader will demand optionality.
The government will demand redundancy.
And the producer will increasingly understand that reliability itself is a commodity.

The war has taught the global economy a simple lesson: energy security is not only about having energy. It is about having enough ways to move it.

And in the years ahead, I believe that question will become almost as important as the price of the barrel itself.
