What Iran's next potential move will mean for energy security

The Israel-Iran confrontation has entered a perilous new phase. Reported Israeli military attacks on Iran's gas sites put energy targets in the crosshairs. Global energy markets might escape crisis this time, but the margin of safety is getting ever narrower.
An onshore site of Phase 14 of the South Pars gasfield, Iran's largest, in the Gulf industrial city of Assaluyeh, was struck, causing an explosion and fire. Iranian news agency Tasnim reported that 12 million cubic metres of gas production a day was halted. The Fajr Jam gas processing plant, near Bushehr, suffered from apparent drone attacks. Phase 14 processes 18.3 billion cubic metres of gas a year and Fajr Jam 20 bcm; the reported damage to the two amounts to about a tenth of Iran's gas output.
Israeli military attacks have also destroyed petrol depots near Tehran. Iran denied reports that the Tabriz refinery was damaged but the Shahr Rey oil refinery south of Tehran was reported to be on fire. In response, an Iranian missile was reported to have hit Israel's Bazan oil refinery in the port of Haifa. As already seen in the Russia-Ukraine war, any taboo about attacking civil infrastructure is long gone.
Oil prices climbed by more than $7 per barrel on the initial news of the air strikes. European natural gas prices are up less than 5 per cent. No doubt they will rise again when markets re-open on Monday. But so far, this remains a moderate response. Crude prices are not yet back to the level on April 2, just before the announcement of US President Donald Trump's massive tariffs and the increase in production by Opec+.
So far, Israel's energy targets appear to be those that serve the domestic market: gas, petrol terminals and oil refineries. It is early summer, and not the peak winter demand season. Still, Iran was already struggling with serious gas and electricity shortages. Exports to Turkey may be affected, but Ankara is already familiar with the unreliability of Iranian supplies, and can increase imports from Russia or buy more liquefied natural gas. Iraq relies on Iranian gas, but it was already facing a cut-off as the US tightened pressure on Baghdad.
So far, Israel has stayed away from sites that directly serve the international market, notably the Kharg oil export terminal in the northern Gulf. This enables Israel to evade immediate responsibility for causing a worldwide energy crisis.
Iran's oil exports, nearly all to China, are about 1.5 million barrels per day. If they were completely cut off, whether by a US blockade or direct Israeli strikes on Kharg and other oil sites, the volumes could quite easily be replaced by the spare capacity in Saudi Arabia, the UAE and elsewhere – assuming that Tehran does not retaliate, a risky assumption.
The crucial question is where things go from here. The stated Israeli goal of eliminating Iran's nuclear programme appears unrealistic; it may be set back, but destruction is not feasible without American involvement. No doubt Israel hopes the US will be sucked in. Even then, the lesson of recent years – Ukraine and Libya contrasted to North Korea and Pakistan – is that those who give up their nuclear weapons are attacked with impunity by those who have them.
Israeli Prime Minister Benjamin Netanyahu's other suggested goal, of toppling the Islamic Republic, is even less plausible. Yes, the regime of Iranian supreme leader Ayatollah Ali Khamenei is repressive and unpopular. Its incompetence in one area where it should be capable has been unmasked by Israel's successes so far, first in severely mauling Hezbollah, then in striking the Iran homeland directly with impunity.
But Iranians have deep memories, personal or learnt, of the resistance to Saddam Hussein's invasion, which also featured extensive bombing of urban areas. Neither democratic nor authoritarian regimes are overthrown by air campaigns alone.
Even a new leadership, perhaps a secular nationalist one, would now seriously have to consider acquiring nuclear weapons. The former Shah, ousted in the 1979 Revolution, himself said, 'If small states began building them, Iran might have to reconsider its policy [of not acquiring nuclear weapons]'.
American diplomacy has been exposed as duplicitous or ineffectual or both. With China wisely sitting out and Russia untrustworthy and stuck in its own war, there is no honest broker at hand. So, it is hard to imagine Iranian diplomats sitting down seriously again to negotiate a halt to their nuclear programme. That would look like a surrender under duress similar to the reviled treaties of Turkmenchay and Golestan that gave up much of Iran's territory to Russia in the early 19th century.
It seems much less likely that Tehran can do as it did in April last year, launching a few face-saving retaliations against Israel and then reaching a ceasefire. Top regime individuals have been killed, military and nuclear sites have suffered damage. Israel will not want to give a respite to Iran to rebuild air defences and harden crucial sites.
Iran does not seem to have the ability to launch a really devastating attack on Israel either, and if it did, it would be met with further reprisal and probably draw in the US. But Tehran also seems unwilling to sit idly by while it is pummelled.
This draws attention to energy targets elsewhere. Mr Trump is acutely sensitive to higher oil prices and inflation. About 20 million barrels of oil and products per day goes through the famous Strait of Hormuz. This includes virtually all the spare production capacity in the Opec+ countries, other than Russia.
Saudi Arabia can divert up to 5 million bpd to the Red Sea, though that brings its own problems. More than half of the UAE's exports, or about 1.8 million bpd, go through a pipeline to Fujairah, outside the strait but still potentially vulnerable. Iraq is mostly friendly to Iran, but its 3.3 million barrels of exports through the Gulf could easily be interrupted by 'accidents'.
Europe, having lost most Russian gas supplies, would be acutely worried about another interruption. About 82 million tonnes of liquefied natural gas, a fifth of global supply, came from the Gulf last year, mostly from Qatar. For Russian President Vladimir Putin, this crisis could bail out his troubled war economy, and bring political gains.
Simply-equipped Houthi troops have been able to shut down most shipping through the southern Red Sea, and have not been prevented by US naval escorts and missile strikes. Iran's planned responses have probably been severely disrupted by the killing of so many of the top brass, but as war so often demonstrates, it is an error to underestimate your enemy forever.
Attacking energy sites or shipments could be one point of leverage for Tehran. It would be very risky. It would cut off its own oil exports, assuming they have not already been disrupted. It would anger China, which brokered the Iran-Saudi rapprochement in March 2023 with a major aim of safeguarding energy supplies. But the remaining Iranian regime may conclude that caution and restraint have not paid off for them so far, despite the calls for calm.
