Iran War Triggers an Energy Crisis No One Can Escape

Iran War Sparks Global Energy Crisis, Exposing Risks No Country Can Escape

A regional conflict becomes a global economic shock

The ongoing war in Iran has rapidly become more than a regional security crisis. It has exposed a deep weakness in the global energy system: the world remains heavily dependent on fossil fuel routes that can be disrupted by conflict, military escalation or political instability.

For many years, the case for clean energy was mostly discussed in future terms. Governments, investors and climate experts spoke about lower emissions, cheaper electricity, long-term resilience and the need to reduce dependence on coal, oil and gas. But the Iran conflict has changed the nature of that debate. The crisis has shown that energy transition is not only about future climate goals. It is also about present-day economic security.

The International Energy Agency has described the current disruption as one of the greatest threats to global energy security, with trade through the Strait of Hormuz severely affected by the war in the region. The IEA notes that the conflict has created the largest supply disruption in the history of the global oil market and has also reduced global liquefied natural gas supply.

Why the Strait of Hormuz matters

At the centre of the crisis is the Strait of Hormuz, a narrow but extremely important maritime route between the Persian Gulf and the Gulf of Oman. It is one of the most critical energy chokepoints in the world. A large share of global oil and liquefied natural gas passes through this route before reaching markets in Asia, Europe and elsewhere.

When the Strait of Hormuz is disrupted, the consequences are immediate. Oil tankers are delayed, shipping insurance becomes expensive, fuel supplies tighten and global prices rise. The crisis has already affected oil exports from major Gulf producers, including Iraq and other countries that rely on this route to reach international markets.

Reuters reported that Iraq’s oil exports through the Strait of Hormuz fell sharply in April, dropping to only 10 million barrels compared with around 93 million barrels per month before the war. This shows how quickly a military conflict can disturb energy flows that normally support the global economy.

The crisis is not limited to oil

The most visible impact of the Iran war has been the rise in oil prices. However, the crisis is much wider than petrol, diesel or crude oil. The disruption has also affected liquefied natural gas, fertilizer, shipping fuel, industrial materials and global supply chains.

This is important because energy is connected to almost every part of the economy. Oil powers transport and logistics. Natural gas is used in power generation and fertilizer production. Fertilizer supports agriculture and food production. Shipping fuel keeps international trade moving. When one part of this system is disrupted, the impact spreads across many sectors.

The International Food Policy Research Institute reported that in 2024, up to 30% of global fertilizer trade passed through the Strait of Hormuz. The same route also carried an estimated 20% of liquefied natural gas and 27% of globally traded oil. As a result, the conflict has raised concerns not only about energy prices but also about food prices and agricultural production.

Food prices may rise because fertilizer is affected

One of the less obvious but highly serious effects of the Iran war is its impact on fertilizer markets. Fertilizer production is closely linked to natural gas. When gas supply becomes expensive or uncertain, fertilizer production costs rise. When fertilizer prices rise, farmers may reduce usage, which can affect crop yields.

This creates a dangerous chain reaction. A war affecting energy routes can increase fertilizer prices. Higher fertilizer prices can reduce agricultural output. Lower output can increase food prices. Poor households are usually hit hardest because they spend a larger share of their income on food.

Reuters has also noted that fertilizer production is energy-intensive, with energy accounting for a large share of production costs. Since a significant share of global fertilizer trade moves through the Strait of Hormuz, the disruption has direct consequences for food systems around the world.

Even countries with less Gulf oil dependence are affected

The Iran war has shown that no country can fully opt out of an energy crisis. Even countries that do not import much oil directly from the Gulf can still be affected through global prices, shipping costs, inflation, fertilizer shortages and market instability.

This is because energy is priced globally. If supply falls in one region, prices can rise everywhere. A country may not buy oil directly from Iran or the Gulf, but it may still pay more for transport, food, imported goods and industrial inputs. This is why the crisis has become a global economic issue rather than only a Middle Eastern conflict.

In East Africa and other import-dependent regions, the effect may be felt through food insecurity rather than fuel alone. If fertilizer becomes more expensive or difficult to obtain, farmers may struggle to maintain production. This can worsen existing food shortages and place additional pressure on governments and aid agencies.

Japan shows how energy shocks hit financial markets

Japan is an example of how an energy shock can become a financial market problem. Although Japan has strategic petroleum reserves, it remains heavily dependent on imported energy. When global oil prices rise, Japan’s import bill increases. This can weaken the yen, raise inflation and put pressure on financial markets.

The crisis shows that petroleum reserves are useful, but they are not a complete solution. Strategic reserves can help during short-term disruptions, but they cannot fully protect an economy from a prolonged global energy shock.

For countries such as Japan, the problem is not only whether they have emergency fuel stocks. The larger issue is structural dependence on imported fossil fuels. If energy imports become more expensive, the pressure spreads into currency markets, consumer prices and business costs.

The United States is not fully protected either

The United States is a major energy producer, but that does not make it immune to global energy shocks. Oil is traded in international markets. When global prices rise, domestic fuel prices can also rise. This means American households and businesses may still face higher gasoline, diesel and transport costs.

The political impact can also be serious. Fuel prices are highly visible to ordinary citizens. When petrol and diesel prices rise, people feel the pressure immediately. This can reduce public confidence in the government’s ability to manage the economy.

Reuters reported that the prolonged conflict with Iran has become a major political challenge for President Donald Trump, with the crisis affecting fuel prices and public confidence.

India’s case shows both vulnerability and resilience

India provides an important example of the mixed effects of this crisis. The country is highly dependent on imported crude oil, so any sharp rise in global oil prices affects its economy. Higher crude prices increase the import bill, put pressure on the rupee, raise transport costs and make inflation harder to control.

At the same time, India has also invested heavily in renewable and non-fossil electricity capacity. This does not fully protect India from oil shocks because oil is still central to transport, logistics and manufacturing. However, it does reduce pressure on the electricity system.

This distinction is important. Clean energy does not make a country completely independent from global markets. But it can reduce exposure. A country with more domestic renewable electricity may have more room to manage imported fuel shocks than a country that depends heavily on imported fossil fuels for both power and transport.

Clean energy is now an energy security strategy

The Iran war has changed the investment case for clean energy. Earlier, renewable energy was mainly promoted for climate reasons. Solar, wind and battery technologies were seen as tools to reduce emissions and meet climate targets. Later, falling costs made clean energy financially attractive.

Now, the crisis has added another argument: energy security.

A renewable energy system is not risk-free. Solar panels, wind turbines, batteries and transmission grids require minerals, finance, land and industrial supply chains. However, once a solar or wind plant is built, it does not need daily fuel shipments through a war-affected maritime chokepoint. This makes clean energy fundamentally different from oil and gas systems that depend on continuous international fuel flows.

The crisis has therefore made clean energy look less like an environmental choice and more like an economic shield.

Fossil fuels no longer look like the stable option

For decades, fossil fuels were treated as the stable foundation of the global economy. Governments planned around the assumption that oil and gas supplies would continue moving through global markets, even if prices fluctuated. The Iran war has challenged that assumption.

The fossil fuel system is highly concentrated around specific routes, producers and chokepoints. When one major chokepoint is disrupted, the consequences can be global. This is why the current crisis is being viewed not just as a temporary price shock, but as a warning about structural risk.

Oil futures have already risen because of concerns over limited flows through the Strait of Hormuz and shrinking inventories. The Wall Street Journal reported that Brent and WTI crude prices increased amid worries that the prolonged disruption could intensify inflation and create product shortages.

Europe’s experience offers a lesson

Europe’s experience after the Russian gas crisis in 2022 offers an important comparison. When Russian gas supplies were disrupted, Europe had to reduce demand, diversify supply and accelerate renewable energy expansion. The shift did not remove all energy risks, but it reduced dependence on a single major source.

The same lesson applies to the Iran crisis. Energy resilience does not come from relying on one fuel, one supplier or one shipping route. It comes from diversification. Countries need a mix of domestic renewable power, stronger grids, storage, efficiency measures and diversified supply chains.

Investors are rethinking risk

The crisis is also changing how investors view clean energy. Clean energy infrastructure is increasingly being evaluated not only for climate benefits but also for resilience. Investors are beginning to compare the risks of policy uncertainty in clean energy with the demonstrated volatility of fossil fuel markets.

This is especially important for emerging economies. Countries such as India, Indonesia, Nigeria and others need affordable energy to support development, industry and jobs. But they are also vulnerable to fossil fuel price shocks and currency pressure. Financing clean energy in these countries remains difficult, but the cost of continuing fossil fuel dependence is becoming clearer.

A crisis no country can ignore

The Iran war has made one thing clear: energy dependence is economic exposure. No country can completely escape a global energy shock, but countries can reduce how severely they are affected.

Strategic petroleum reserves, emergency imports and diplomatic efforts can help in the short term. But long-term protection requires a different energy system. Countries that invest in renewable energy, grid infrastructure, storage and efficiency will be better placed to manage future crises.

The central question is no longer whether the energy transition will happen. It is already happening. The real question is whether governments and investors are moving quickly enough to build systems that reflect the risks of the present world.

The Iran war has exposed the weakness of the old energy order. It has shown that fossil fuel dependence is not just a climate problem. It is a security problem, a food problem, a financial problem and a household cost problem.

Clean energy is no longer only about the future. It is about protecting economies now.
