Israel-Iran war already takes toll on oil and gas sector
LONDON, June 17 (Reuters) - Critical energy infrastructure in Israel and Iran has not escaped unscathed from the first few days of the countries' escalated conflict. Worst-case scenarios have yet to be realized, but the war is already having a notable impact on energy production and exports in both countries.
Benchmark Brent crude oil prices jumped 7% to over $74 a barrel on Friday after Israel launched an unprecedented wave of airstrikes on Iran, prompting Tehran to fire hundreds of ballistic missiles at Israel.
Some energy facilities have been hit in both countries since then, leading to significant disruptions to production.
However, prices receded slightly on Monday, as it appeared that both sides were not immediately targeting the most sensitive energy infrastructure and supply routes, and following a report that Iran was seeking ceasefire mediation.
Investor focus remains squarely on the Strait of Hormuz, a narrow and vital waterway between Iran and Oman in the Mideast Gulf through which between 18 and 19 million barrels per day of crude oil and fuels flow, nearly a fifth of the world's consumption. Another 85 million tons of liquefied natural gas from Qatar and the United Arab Emirates were also sent through the strait last year, equivalent to around 20% of global demand.
Disrupting maritime activity through the strait would thus severely impact oil and gas markets, pushing prices much higher, possibly into three-digit territory.
This doomsday scenario has not yet played out, but disruption to both Iran's and Israel's energy industries has been meaningful nonetheless.
Perhaps most notably, Iran's oil exports appear to have essentially ground to a halt in recent days. Total Iranian crude and condensate oil exports this week are currently forecast to reach 102,000 bpd, compared with a weekly average of 1.7 million so far this year, according to analytics firm Kpler.
Critically, exports from Kharg Island from which Iran exports over 90% of its oil, appear to have completely halted since Friday. No tankers were anchored at Kharg Island as of Monday, according to LSEG satellite ship tracking data.
However, Iran has roughly 27.5 million barrels stored in tankers outside the Gulf, according to Kpler data, which would enable it to sell oil for a few weeks.
Iran has produced an average of 3.4 million bpd of crude oil and another 1.3 million bpd of condensate so far in 2025, according to the U.S. Energy Information Administration, with China appearing to be the main buyer.
Israel has also directly targeted some Iranian energy infrastructure.
Iran on Saturday partially suspended, opens new tab gas production at the South Pars gas field in the Mideast Gulf, in what was probably Israel's first strike on the country's oil and gas sector. South Pars, which is shared with Qatar, is the world's biggest gas field. It produces around 610 million cubic meters of natural gas per day, accounting for around 80% of Iran's total gas output, opens new tab.
The portion controlled by Qatar, referred to as the North Field, provides the natural gas for the Gulf state's enormous LNG industry.
The field also produces around 700,000 barrels of per day of condensate, a light oil that is used as feedstock to produce fuels and petrochemicals. The Persian Gulf Star condensate refinery, which became Iran's largest refinery when it came online in 2017, can process 420,000 bpd of condensates from South Pars.
While the extent of the damage to the South Pars field is unknown, any serious issues could meaningfully impact condensate production.
In addition, Israel has targeted the Shahr refinery outside Tehran as well as a number of fuel depots around the capital city. Again, the full impact of these strikes on production is unknown.
The conflict has also already had a significant effect on Israel's energy industry. Israel on Friday shut down two of its three offshore natural gas fields, the Chevron-operated Leviathan field, opens new tab and Energean's Karish field, reducing Israel's supply by nearly two thirds. While the country's Tamar field continues to operate, Israel will have to turn to coal and fuel oil as a substitute for the gas in its power plants.
These supply outages have had a meaningful impact on Israel's gas exports. Leviathan produced 11.33 billion cubic meters (bcm) in 2024, most of which is exported to neighbouring Egypt and Jordan.
Israeli gas accounts for about 15-20% of Egypt's consumption, data from the Joint Organisations Data Initiative (JODI) shows. The disruption of Israel's gas supply led Egyptian fertilizer producers to halt operations on Friday.
Finally, the ORL oil refinery in Haifa, one of Israel's two refineries, said on Monday it had shut down all its facilities after a power station used to produce steam and electricity was significantly damaged in an Iranian missile strike.
It remains to be seen how long the two sides will continue to exchange blows. If a ceasefire is quickly reached, the ultimate impact on energy markets could be relatively limited. But given how much this conflict has escalated in only a few days, the worst-case scenarios cannot be fully discounted.

Iran's Atomic Energy Organization says it will not allow nuclear development to stop
CAIRO, June 22 (Reuters) - Iran's Atomic Energy Organization said on Sunday it would not allow the development of its "national industry" - an apparent reference to the country's nuclear development - to be stopped. It also said the attacks on its nuclear sites violate international law, without clarifying the extent of the damage from the U.S. strikes that President Donald Trump announced earlier.

Trump says Iran strikes ‘spectacular military success' and warns ‘bully' Iran to ‘make peace' or face ‘greater' attacks
President Donald Trump on Saturday said the 'mass precision strikes' carried out by American bombers on a trio of Iranian nuclear facilities had been successful and warned that more of the same could be on the table if Tehran does not return to negotiations. Speaking from the Cross Hall in the White House and flanked by Vice President JD Vance, Defense Secretary Pete Hegseth and Marco Rubio, the ex-Florida senator who serves as hisnational security adviser as well as Secretary of State, the president described the airstrikes as 'a spectacular military success' and said the three facilities targeted by U.S. warplanes had been 'completely and totally obliterated.' 'Iran, the bully of the Middle East, must now make peace. If they do not, future attacks will be far greater and a lot easier,' he said. Trump thanked Israeli Prime Minister Benjamin Netanyahu and Israeli forces for the 'wonderful job' they've done during a week-long campaign to take out much of Iran's nuclear and military capabilities, and said the Israeli operation — along with tonight's American airstrikes — had 'gone a long way to erasing this horrible threat to Israel' from the Iranian nuclear program. He also warned Tehran that their aggression in the region and their nuclear ambitions 'cannot continue' and cautioned Iranian leaders not to retaliate. 'There will be either peace or there will be tragedy for Iran, far greater than we have witnessed over the last eight days. Remember, there are many targets left. Tonight's was the most difficult of them all, by far, and perhaps the most lethal. But if peace does not come quickly, we will go after those other targets with precision, speed and skill, most of them can be taken out in a matter of minutes,' he said. The president's remarks came just hours after he took to Truth Social to announce that U.S. forces had struck Iranian nuclear facilities in Natanz and Esfahan, as well as the Fordow enrichment facility hidden in a mountain near the city of Qom, ending days of speculation over whether he'd order American forces to join Israel's week-old campaign to knock out Tehran's nuclear weapons program with a surprise attack aimed at bringing Iranian officials back to the negotiating table.

US strikes three Iranian nuclear sites
President Donald Trump said that the United States military struck three sites in Iran, directly joining Israel's effort to decapitate the country's nuclear programme in a risky gambit to weaken a longtime foe amid Tehran's threat of reprisals that could spark a wider regional conflict. Iran's state-run IRNA news agency, quoting a provincial official, confirmed attacks on Fordo, Isfahan and Natanz nuclear sites. Advertisement The decision to directly involve the US in the war comes after more than a week of strikes by Israel on Iran that have moved to systematically eradicate the country's air defences and offensive missile capabilities, while damaging its nuclear enrichment facilities. — Donald J. Trump (@realDonaldTrump) June 21, 2025 US and Israeli officials have said that American stealth bombers and the 30,000-pound (13,500-kg) bunker buster bomb they alone can carry offered the best chance of destroying heavily-fortified sites connected to the Iranian nuclear programme buried deep underground. 'We have completed our very successful attack on the three Nuclear sites in Iran, including Fordow, Natanz, and Esfahan,' Mr Trump said in a post on social media. 'All planes are now outside of Iran air space. A full payload of BOMBS was dropped on the primary site, Fordow. All planes are safely on their way home.' Advertisement Mr Trump added in a later post that he would address the national audience at 10pm eastern time, writing: 'This is an HISTORIC MOMENT FOR THE UNITED STATES OF AMERICA, ISRAEL, AND THE WORLD. IRAN MUST NOW AGREE TO END THIS WAR. THANK YOU!' Trump said B-2 stealth bombers were used but did not specify which types of bombs were dropped. The White House and Pentagon did not immediately elaborate on the operation. The strikes are a perilous decision for the US as Iran has pledged to retaliate if it joined the Israeli assault, and for Mr Trump personally, having won the White House on the promise of keeping America out of costly foreign conflicts and scoffed at the value of American interventionism. Trump told reporters on Friday that he was not interested in sending ground forces into Iran, saying it's 'the last thing you want to do.' He had previously indicated that he would make a final choice over the course of two weeks, a timeline that seemed drawn out as the situation was evolving quickly. Advertisement Iran's Supreme Leader Ayatollah Ali Khamenei warned the United States on Wednesday that strikes targeting the Islamic Republic will 'result in irreparable damage for them'. Iranian foreign ministry spokesman Esmail Baghaei declared 'any American intervention would be a recipe for an all-out war in the region'. Trump has vowed that he would not allow Iran to obtain a nuclear weapon and he had initially hoped that the threat of force would bring the country's leaders to give up its nuclear program peacefully. Israel 's military said Saturday it was preparing for the possibility of a lengthy war, while Iran's foreign minister warned before the U.S. attack that American military involvement 'would be very, very dangerous for everyone.' Advertisement The prospect of a wider war threatened, too. Iranian-backed Houthi rebels in Yemen said they would resume attacks on U.S. vessels in the Red Sea if the Trump administration joins Israel's military campaign. The Houthis paused such attacks in May under a deal with the US. The US ambassador to Israel announced the US had begun 'assisted departure flights,' the first from Israel since the Hamas-led attack on October 7, 2023, that sparked the war in Gaza. White House press secretary Karoline Leavitt said at Thursday's press briefing that Trump had said: 'I will make my decision whether or not to go within the next two weeks.' Instead, the U.S. president struck just two days later. Trump appears to have made the calculation — at the prodding of Israeli officials and many Republican lawmakers — that Israel's operation had softened the ground and presented a perhaps unparalleled opportunity to set back Iran's nuclear program, perhaps permanently. Advertisement The Israelis say their offensive has already crippled Iran's air defences, allowing them to already significantly degrade multiple Iranian nuclear sites. But to destroy the Fordo nuclear fuel enrichment plant, Israel appealed to Trump for US bunker-busting bomb, which uses its weight and sheer kinetic force to reach deeply buried targets and then explode. The penetrator is currently only delivered by the B-2 stealth bomber, which is only found in the American arsenal. The bomb carries a conventional warhead, and is believed to be able to penetrate about 200 feet (61 meters) below the surface before exploding, and the bombs can be dropped one after another, effectively drilling deeper and deeper with each successive blast. The International Atomic Energy Agency has confirmed that Iran is producing highly enriched uranium at Fordo, raising the possibility that nuclear material could be released into the area if the GBU-57 A/B were used to hit the facility. Previous Israeli strikes at another Iranian nuclear site, Natanz, on a centrifuge site have caused contamination only at the site itself, not the surrounding area, the IAEA has said. Mr Trump's decision for direct US military intervention comes after his administration made an unsuccessful two-month push — including with high-level, direct negotiations with the Iranians — aimed at persuading Tehran to curb its nuclear programme. For months, Mr Trump said he was dedicated to a diplomatic push to persuade Iran to give up its nuclear ambitions. And he twice — in April and again in late May — persuaded Israeli Prime Minister Benjamin Netanyahu to hold off on military action against Iran and give diplomacy more time. The US in recent days has been shifting military aircraft and warships into and around the Middle East to protect Israel and US bases from Iranian attacks. All the while, Mr Trump has gone from publicly expressing hope that the moment could be a 'second chance' for Iran to make a deal to delivering explicit threats on Mr Khamenei and making calls for Tehran's unconditional surrender. 'We know exactly where the so-called 'Supreme Leader' is hiding,' Mr Trump said in a social media posting. 'He is an easy target, but is safe there – We are not going to take him out (kill!), at least not for now.' The military showdown with Iran comes seven years after Mr Trump withdrew the US from the Obama-administration brokered agreement in 2018, calling it the 'worst deal ever'. The 2015 deal, signed by Iran, US and other world powers, created a long-term, comprehensive nuclear agreement that limited Tehran's enrichment of uranium in exchange for the lifting of economic sanctions. Mr Trump decried the Obama-era deal for giving Iran too much in return for too little, because the agreement did not cover Iran's non-nuclear malign behaviour. Mr Trump has bristled at criticism from some of his Maga faithful, including conservative pundit Tucker Carlson, who have suggested that further US involvement would be a betrayal to supporters who were drawn to his promise to end US involvement in expensive and endless wars.
