Oil prices jumped sharply this week after Israel reportedly hit Iran's biggest gas field, kicking off a dangerous tit-for-tat on vital energy infrastructure across the Middle East. It's a major escalation, the first time Iran's fossil fuel production has been directly targeted since the war began. That's got everyone worried about global supplies.

A New Kind of War

Israeli media widely reported the strike on Iran's massive South Pars gasfield. This field, shared with Qatar, holds the world's largest gas reserves. Thing is, until now, US and Israeli operations had mostly avoided Iran's oil and gas sector. That helped keep a lid on rising global oil prices. No longer. This attack on the heart of Iran’s gas infrastructure marks a key shift in how the conflict is playing out.

And Iran didn't waste any time. Its Revolutionary Guards quickly threatened counterstrikes. They warned that several energy facilities across Saudi Arabia, the UAE, and Qatar were now "direct and legitimate targets." These weren't vague threats either. They named names: Saudi Arabia's Samref refinery and Jubail petrochemical complex, the UAE's al-Hosn gasfield, and Qatar's Mesaieed petrochemical complex and Ras Laffan refinery. The Guards even told people to evacuate these areas "without any delay."

Eskandar Pasalar, the governor of Asaluyeh in southern Iran, didn't mince words. He called the US-Israeli escalation "political suicide," telling state media that "the pendulum of war has swung" to a "full-scale economic war."

Market Reaction and Supply Fears

Global oil prices shot up fast.

The international oil benchmark climbed by as much as 5%, hitting a high of $108.60 a barrel. Over in Europe, the gas benchmark jumped more than 7.5%, pushing past €55.50 a megawatt hour.

That's a big move.

Why the jump? It's simple supply and demand. The mounting threat to the Gulf’s oil and gas infrastructure fuels concerns of more disruption to global supplies. On top of that, Iran's continuing blockade of the Strait of Hormuz is already a massive problem.

Mastheads

This narrow waterway is a choke point for a huge chunk of the world's oil.

Daily oil exports from the region have already plunged by at least 60% compared to pre-war levels. That's because of the constant drone and missile strikes, plus Iran’s effective control over the Strait. It's forced Gulf neighbours to cut back on their own oil and gas production. Their pipelines and storage facilities are simply reaching capacity, with nowhere for the product to go.

Regional Instability Spreads

This isn't the first time Iran has gone after energy sites. The third week of war began with Iranian attacks on the UAE’s Shah natural gasfield — one of the biggest in the world. An oilfield in Iraq, Majnoon, also got hit. And the UAE’s biggest port and oil storage facility, Fujairah, was targeted by Iranian drones and missiles.

The UAE isn't happy about it. Its Foreign Ministry called the attacks on its gas facilities and oil field a "dangerous escalation" and a breach of international law. Qatar's government spokesperson, Majid al-Ansari, echoed those concerns. He warned that targeting energy infrastructure "constitutes a threat to global energy security, as well as to the peoples of the region and its environment."

US President Donald Trump has said he doesn't want any more strikes on Iranian energy sites after Israel's attack. But he also left the door open, saying he could be "open to targeting more Iranian energy facilities depending on Tehran’s future actions in strategic waterways."

Australian Households Feel the Pinch

For Australians, this escalating conflict in the Middle East isn't just a distant geopolitical issue — it's got real economic implications. Australia relies heavily on imported crude oil and refined petroleum products. So, when global oil prices shoot up, as they have this week, it directly impacts the cost of fuel at the pump. That means higher transport costs for businesses and consumers alike.

The ripple effect is wide. Everything from groceries to manufacturing costs can climb.

Plus, many Australian industries depend on stable, affordable energy. Any sustained disruption or price hike from the Gulf region—a key global energy hub—could squeeze profit margins and slow economic activity here at home. Australia is also a big exporter of LNG, but global instability in energy markets can still create volatility even for producers, affecting contract prices and investment decisions.

Higher energy costs also feed into inflation. The Reserve Bank of Australia is always watching for these pressures.

If inflation keeps rising because of international events like these, it could influence future interest rate decisions, potentially impacting mortgage holders and borrowers. It's a complex web.
