U.S. President Donald Trump appears to have set his eyes on Greenland again while venting frustration at NATO, as the diplomatic fallout from Iran war exposes rifts in Washington’s ties with the security alliance.

In a Truth Social post Wednesday evening stateside, Trump said that “NATO WASN’T THERE WHEN WE NEEDED THEM, AND THEY WON’T BE THERE IF WE NEED THEM AGAIN. REMEMBER GREENLAND, THAT BIG, POORLY RUN, PIECE OF ICE!!!”

The latest broadside comes after Trump announced a 2-week ceasefire after more than a month of fighting with Iran. Trump has repeatedly criticized NATO members for not joining the war effort in Iran, saying his call for action was “a great test,” while threatening to pull out of the alliance.

Trump has taken aim at NATO and Greenland in recent days. “It all began with, if you want to know the truth, Greenland,” Trump told reporters at a White House press conference Monday. “We want Greenland. They don’t want to give it to us. And I said, ‘bye, bye.'”

U.S. relations with European allies have frayed after Trump threatened tariffs on European countries and signaled military action to acquire Greenland, a Danish autonomous territory. In January, Trump said he and NATO Secretary General Mark Rutte had reached “the framework of a future deal with respect to Greenland.”

The Iran war has brought fresh tensions in the diplomatic ties, as several NATO members have resisted supporting the U.S.-Israeli military campaign against Iran, denying American military aircraft use of their airspace and declining to contribute naval forces to efforts aimed at reopening the Strait of Hormuz to energy shipping.

Trump’s comments Wednesday followed a meeting with Rutte at the White House earlier in the day, with spokeswoman Karoline Leavitt reportedly saying that NATO had “turned their backs on the American people.”

Rutte acknowledged the friction, in an interview with CNN following the meeting, saying that “He is clearly disappointed with many NATO allies, and I can see his point.”

Last week, Trump called NATO a “paper tiger” and said he was “absolutely” considering to withdraw from the 32-member alliance, arguing that European members have relied on U.S. security guarantees while offering inadequate support when Washington needed them most.

“Trump can’t attack the alliance forever without making it hollow,” said Michael Feller, chief strategist at Geopolitical Strategy, as Iran was “testing unity” by offering Spain and Turkey waivers to get their oil via the Strait of Hormuz.

Alongside Trump’s remarks, the Pentagon timed leaks on new military activities in Greenland, Feller said referring to a New York Times report earlier this month on the Pentagon looking for military expansion in Greenland. The U.S. was in talks with Denmark for access to three additional bases in Greenland, in what would be the first U.S. expansion there in decades, according to the report.

“This doesn’t augur invasion, but is likely designed to intimidate,” Feller said.

Meanwhile, less than 24 hours into the truce with Iran, the country’s parliamentary speaker Mohammad Bagher Ghalibaf said that Washington had violated the terms of the ceasefire deal.

Israel reportedly launched its heaviest strikes yet on Lebanon, killing hundreds of people and drawing a threat from Iran, saying that it would be “unreasonable” to proceed with peace talks with the U.S., underscoring the fragility of the ceasefire agreement.

Oil prices rose Thursday after Iran accused the United States of violating elements of a two-week ceasefire agreement, raising concerns that tensions could escalate again and disrupt energy supplies.

International benchmark Brent crude futures for June delivery rose 2.52% to $97.14 while the U.S. West Texas Intermediate crude futures for May added 2.72% to $96.96 per barrel.

The moves come a day after U.S. crude oil posted their biggest single-day drop since 2020.

Mohammad Bagher Ghalibaf, Iran’s parliamentary speaker, said on Wednesday that Washington had breached the terms of the ceasefire deal.

“The deep historical distrust we hold toward the United States stems from its repeated violations of all forms of commitments — a pattern that has regrettably been repeated once again,” Ghalibaf said in a statement posted on social media.

Ghalibaf said three elements of Iran’s 10-point truce proposal had been violated: Israel’s ongoing strikes in Lebanon, a drone entering Iranian airspace, and what he described as the denial of Tehran’s right to enrich uranium.

U.S. President Donald Trump had said Tuesday stateside that Iran’s proposal could serve as a basis for talks.

Vice President JD Vance responded to the allegations while on a trip to Hungary on Wednesday. “Ceasefires are always messy,” Vance said, addressing the reported drone incident in Iranian airspace. He added that Washington maintains Iran should not be allowed to enrich uranium, and said any ceasefire covering Lebanon had not been included in the agreement.

Now that oil is below $100 per barrel, refiners should “use this window to resume more opportunistic buying,” said Rystad Energy’s vice president of commodity markets, Janiv Shah. 

“However, the transition period itself could present the next challenge. If refiners delay purchases in anticipation of further price declines while physical flows remain constrained, product tightness could worsen even amid de-escalation,” he added.

A temporary U.S.-Iran ceasefire sparked a broad relief rally across assets on Wednesday, but experts warned that any deal concerning lasting peace will be complicated by a major trust deficit.

The ceasefire came following hastened diplomatic efforts led by Pakistan and just hours before Trump’s threatened deadline for wiping out the entire Iranian civilization, briefly pulling the region back from the brink of a massive military bombardment.

Oil prices cooled to below $100 per barrel following the ceasefire announcement, but remain far above the pre-war levels of around $70 per barrel.

While U.S. President Donald Trump said the two-week ceasefire was contingent on the “complete, immediate, and safe opening” of the Strait of Hormuz, Iranian officials stated that safe passage through the strait would be “possible,” subject to coordination with its armed forces and “technical limitations” — caveats that may give Iran some room to define compliance on its own terms.

“This is a problem that could derail the ceasefire later this year,” said Matt Gertken, chief geopolitical strategist at BCA Research, warning that the coordination requirement remains a risky ambiguity in both sides’ statements so far.

Trump may temporarily accept Iran as a gatekeeper — with U.S. midterm elections approaching and gasoline prices sharply higher than before the war — but after the election, the U.S. national security establishment will start to demand a more permanent solution,” said Gertken. “Fighting will ignite later this year, if not later this month.”

Tehran also said that its armed forces will cease defensive operations if attacks against Iran are halted. After the ceasefire came into effect at 8 p.m. ET Tuesday, missiles were still launched from Iran towards Israel and several Gulf states.

The reprieve on Tuesday would allow some time for the two sides to reach a longer agreement to end the six-week-old war, which has killed thousands of people and sparked a global energy crisis, with their delegations expected to meet in Islamabad on Friday.

Iran is reportedly finalizing a joint maritime protocol with Oman to institutionalize coordinated management of tanker traffic through the strait, which could embed Iranian authority over the crucial energy artery into a standing bilateral agreement.

Israel agreed to suspend strikes but urged Washington to press for deeper Iranian concessions, including the surrender of enriched uranium stockpiles. In its 10-point terms, Iran requested Washington to accept its uranium enrichment program and the lifting of all sanctions.

The ceasefire will likely hold in the near term, given the economic costs accruing to the global economy from six weeks of conflict, said Michael Langham, emerging markets economist at Aberdeen Investments. “Parties with vested interest in stopping the conflict and reopening the strait will double down on efforts to find a compromise,” he said.

If the truce holds and the strait reopens, the global economic damage should prove manageable, Langham added. Central banks could broadly resume their pre-conflict paths — and attention may shift from inflation to growth, if commodity prices normalize quickly, he added.

The ceasefire sparked a relief rally in markets amid repricing for a de-escalation in the conflict, but investors will watch for something more durable than a two-week pause, Geoff Yu, senior market strategist at BNY, said on CNBC’s “Squawk Box Asia” on Wednesday.

“What the market is going to start pricing ahead is a first step towards further de-escalation and perhaps something more permanent,” he said, flagging that the disruption has extended beyond crude oil to commodities such as helium, critical to semiconductor manufacturers in South Korea and Taiwan.

The sprawling Middle East crisis is expected to spur drivers to abandon traditional internal combustion engine vehicles in favor of EVs, analysts told CNBC, although early evidence suggests this will be a gradual gearshift.

The Iran war has severely disrupted oil exports through the strategically vital Strait of Hormuz, which typically carries about a fifth of the world’s oil and liquified natural gas (LNG). It has underlined the extent to which the world remains deeply reliant on fragile fossil fuel trade routes, while surging oil and gas prices have jolted energy markets and triggered widespread inflation fears.

Various car-selling platforms in the U.S. and Europe have reported a sharp increase in consumer interest for EVs since the war began in late February. The burgeoning trend comes even as a large chunk of the legacy car industry pivots back to internal combustion engine (ICE) vehicles.

Autotrader, an online vehicles marketplace, reported on March 26 a 28% jump in inquiries about buying a new EV and a 15% increase in inquiries about buying a used one, since the war in Iran started on Feb. 28. EV specialist Octopus Electric Vehicles said on March 25 it had seen EV leasing inquiries rise 36% since the start of the conflict.

But U.S. automakers Ford Motor, General Motors and Jeep owner Stellantis have all reversed course on EV strategies, booking tens of billions of dollars in combined write-offs and restructuring costs, in part due to lackluster consumer demand and shifting political landscapes.

Steffen Michulski, senior consultant at JATO Dynamics, said that while the situation is still evolving, it was already clear that the fallout from the Iran war could influence EV demand.

Owning a battery electric vehicle (BEV) has become more compelling for drivers covering a lot of mileage, Michulski said, given that a sharp rise in oil prices has made conventional gasoline cars much more expensive.

Switching to an EV may also provide households with an extra layer of energy independence, Michulski said, although he cautioned that it would be important not to “oversimplify” the situation. He pointed out that the overall economic environment may soften if inflation and supply chain costs continue to rise, for example, with these broader pressures impacting all powertrains — electric or combustion.

“To shorten and summarize it: Yes, elevated oil prices and the renewed focus on energy security are likely to provide a mid term boost to BEV demand,” Michulski told CNBC by email.

“But this is best understood as an incremental shift rather than a sudden market wide acceleration. Electricity price risks, technological progress on the combustion side, and general economic uncertainty all act as counterweights,” he added.

An analysis published by Transport & Environment earlier this month found that electric cars were already cutting the European Union’s oil imports, noting that the nearly 8 million EVs in the EU will save the bloc around 46 million barrels of oil in 2025. That’s the equivalent of almost 3 billion euros ($3.45 billion) in avoided oil import costs.

In the context of the Middle East conflict, meanwhile, the analysis said that petrol drivers were expected to be five times more exposed to higher oil prices than EV owners.

Poliscanova said EV growth drivers in Asia, notably Vietnam, Thailand and Indonesia, which all benefit from affordable models by Chinese car manufacturers, were all likely to see an accelerated shift away from fossil fuels.

“We’re likely to see an even faster shift in some of these economies away from oil, meaning that we in Europe today, still discussing things like biofuels and hybrids, just look really stupid and detached from the reality,” Poliscanova said.

A spokesperson for the European Commission, the EU’s executive arm, declined to comment.

The fallout from the Iran war is likely to expedite the shift away from fossil fuels and make countries think differently about the role renewables can play in shoring up energy security, analysts told CNBC.

The Middle East crisis has severely disrupted oil exports through the strategically vital Strait of Hormuz, which typically carries about a fifth of the world’s oil and liquified natural gas (LNG) and represents a key choke point for fertilizer trade.

It has shone a light on the extent to which the world remains deeply reliant on fragile fossil fuel trade routes, while surging oil and gas prices have rattled energy markets and triggered widespread inflation fears.

Asia’s reliance on imported energy means it now sits at the forefront of the global fossil fuel crisis, but supply disruptions are also hitting hard in Europe and Africa, where countries are responding to rising fuel costs and a considerable threat to food security.

The head of the International Energy Agency said the energy transition was moving “very strongly” before the Iran war began — but the fallout from the resulting energy shock means countries will likely direct even more investment toward clean energy sources.

“I expect one of the responses to this crisis will be [an] acceleration of renewables. Not only because they are helping to reduce the emissions but also, they are [a] homegrown domestic energy source,” IEA Executive Director Fatih Birol said at the National Press Club in Australia’s capital on Monday.

Clean energy sources dominated new power installations last year, for example, with renewables accounting for 85% of all new global power capacity, Birol said, citing solar as a primary driver of this trend.

“It is amazing. Ten years ago, solar was a romantic story — but now solar is a business,” Birol said.

Fossil fuels, however, such as coal, oil and gas, continue to dominate the global energy mix, meeting around 80% of worldwide demand in 2023, according to the IEA.

“The Iran crisis accelerates the shift to renewables and electrification. High fossil prices drive switching, making already cheap electrotech even more competitive,” Sam Butler-Sloss, research manager at global energy think tank Ember, told CNBC by email.

“In the old fossil fuel world, energy security meant diversifying fuel supply. With electrotech, nations now have the tools to increasingly eliminate imported fuels altogether.”

Electrotech, which refers to solar, wind, batteries and electrified transport, heating and industry, became the world’s dominant engine of global energy growth last year, Ember found in an analysis published in December. This was led by China’s emergence as the world’s first so-called “electrostate.”

Butler-Sloss said electric vehicle adoption had already been rising fast across the world, particularly in Asia, and this crisis adds a further tailwind to that trend. He estimated that scaling up EVs could save importers more than $600 billion a year in oil imports, describing the switch as a “security superlever.”

“This is Asia’s Ukraine moment. In the same way Ukraine compelled Europe to cut gas dependency, Hormuz will push Asia to cut oil dependency – but with even cheaper technology available,” Butler-Sloss said.

Ana Maria Jaller-Makarewicz, lead energy analyst for the Europe team at the Institute for Energy Economics and Financial Analysis (IEEFA), described the Iran war energy shock as “a wake-up call” for the European Union.

Spain serves as a prime example of how countries have been able to limit their exposure to fossil fuel price volatility, Jaller-Makarewicz said.

She noted that Spain’s government had come under heavy criticism following a catastrophic blackout last year, which some policymakers blamed on renewables, but that the country was now reaping the rewards from its investment in wind and solar technologies.

U.S. President Donald Trump on Wednesday warned that if Iran continued targeting Qatar’s energy facilities, America would “massively blow up the entirety of the South Pars Gas Field.”

Tehran has attacked a key energy facility in Qatar after Israel bombed the South Pars Gas in Iran, signaling a sharp escalation in the conflict and sending energy prices soaring.

Qatar said Wednesday that Iranian missiles caused “extensive damage” at Ras Laffan Industrial City, home to the largest liquefied natural gas, or LNG, export facility in the world.

Trump also denied any prior knowledge of Israel attacking South Pars, pushing back against reports that the strike was coordinated with and approved by his administration.

In a social media post Wednesday night stateside, Trump said that “the United States knew nothing about this particular attack, and the country of Qatar was in no way, shape, or form, involved with it, nor did it have any idea that it was going to happen.”

Trump also urged Israel to end attacks on the South Pars gas field, unless Iran “unwisely” decides to attack Qatar. In that case, the U.S. will “massively blow up the entirety of the South Pars Gas Field at an amount of strength and power that Iran has never seen or witnessed before.”

The attack on South Pars — the world’s largest natural gas reserve, shared between Iran and Qatar — marked the first time Israel has targeted Iranian natural gas production infrastructure since the conflict began on Feb. 28.

Iran has fired ballistic missiles at Qatar’s Ras Laffan Industrial City, with ​QatarEnergy saying the attack had caused “extensive damage” warranting deployment of emergency response teams to contain fires at the site. No casualties were reported.

Separately, Reuters reported Thursday that the U.S. government was considering deploying thousands of U.S. forces to the Middle East, raising the prospect of further escalation.

As tensions spiral, world leaders are scrambling to contain the Middle East conflict amid fears of deepening the turmoil in global energy markets.

German Foreign Minister Johann Wadephul on Wednesday warned of a “crisis of the gravest order” if global supply chains continued to be disrupted, calling for a path toward de-escalation and a cessation of hostilities once U.S. and Israeli military objectives are achieved, according to local media reports.

The United Arab Emirates called the targeting of energy facilities linked to the South Pars field in Iran a “serious escalation,” posing “a direct threat to global energy security” with severe environmental repercussions.

The UAE Ministry of Foreign Affairs also called Iran’s targeting of its Habshan gas facility and Bab field a “terrorist attack,” risking a “dangerous escalation.”

Qatar’s foreign ministry spokesperson Majed al-Ansari described the Israeli strike on South Pars as “a dangerous and irresponsible step” amid escalating regional tensions.

The Gulf nation has declared Iranian military and security attachés and their staff at the Iranian embassy in Doha “persona non grata,” ordering them to leave the country within 24 hours.

Saudi Arabia’s Foreign Minister Prince Faisal bin Farhan Al Saud also appeared to toughen the tone, reportedly saying that “what little trust there was before with Iran has completely been shattered.” Both political and non-political responses to Iran remain on the table, he added.

Iran’s Islamic Revolutionary Guard Corps on Wednesday threatened to escalate hostilities by targeting oil and gas facilities in Saudi Arabia, the UAE, and Qatar.

In a post on X, Iran’s President Masoud Pezeshkian condemned the strikes on Iran’s energy infrastructure, saying that they “could have uncontrollable consequences, the scope of which could engulf the entire world.”

The attacks on Middle East energy production facilities have further deepened supply disruption triggered by the conflict. Brent crude May futures rose 4% to $111.77 a barrel as of 10:25 p.m. ET , while U.S. West Texas Intermediate futures for April climbed over 1.3% to $97.56 per barrel.

Oil tanker traffic through the Strait of Hormuz — a vital chokepoint for one-fifth of global oil supply and a significant share of LNG exports — has plunged since the war began, with the waterway effectively closed to most commercial shipping.

A fresh wave of attacks on the United Arab Emirates’ energy infrastructure has ramped up concerns over prolonged supply disruptions amid the Iran war.

It comes after the world’s largest ultra-sour gas development was struck by a drone, a fire broke out in the UAE’s Fujairah Oil Industry Zone, and another tanker was hit near the strategically vital Strait of Hormuz.

The UAE also reopened its airspace on Tuesday after a brief shutdown following a fire caused by an Iranian drone attack hitting a fuel tank.

Operations at the UAE’s massive Shah gas field remained suspended on Tuesday following a drone attack, which caused a fire at the facility, according to Abu Dhabi authorities. No injuries were reported from the incident.

The Shah gas field is located 180 kilometers southwest of Abu Dhabi and is operated by a joint venture between ADNOC and Occidental Petroleum Corp. It has the capacity to produce 1.28 billion standard cubic feet of gas per day and 4.2 million tons of sulfur per year.

Separately, a drone attack sparked a fire at the Fujairah Oil Industry Zone, a critically important hub for the UAE’s crude exports and bunkering operations. The Fujairah government’s media office said on Tuesday that no casualties were reported.

Fujairah, one of the world’s top hubs for storing crude and fuels, is located on the eastern seaboard of the UAE and serves as a key shipping hub for the wider region.

It has faced repeated attacks in recent weeks, underlining the vulnerability of the UAE’s only export route that bypasses the Strait of Hormuz.

Shipping traffic through the Strait of Hormuz, one of the world’s most important energy choke points, has virtually ground to a halt since the U.S. and Israel launched strikes against Iran on Feb. 28. Iran has retaliated by targeting ships trying to pass through the maritime corridor.

Spanning around 248 miles from onshore oil facilities at Habshan to Fujairah, the UAE’s Abu Dhabi Crude Oil Pipeline (ADCOP), or the Habshan–Fujairah oil pipeline, is estimated to handle 1.5 million barrels per day, with a reported total capacity of close to 1.8 million barrels per day.

A tanker was also struck while at anchor by an unknown projectile about 23 nautical miles east of the UAE’s Fujairah in the Gulf of Oman, according to an update published Monday from the United Kingdom Maritime Trade Operations (UKMTO) center.

The incident caused minor structural damage, with no injuries to the crew and no environmental impact was reported, the UKMTO said.

The latest report comes after six vessels sustained damage in and around the Persian Gulf, Strait of Hormuz and Gulf of Oman last week as Iran warned oil prices could climb to $200 a barrel.

Oil prices were higher on Tuesday as energy market participants closely monitored ongoing supply disruptions.

International Brent crude futures with May delivery advanced 2.2% at $102.36 per barrel, while U.S. West Texas Intermediate futures with April delivery rose 2.2% at $95.55.

Prices have surged about 40% during the U.S.-Iran war, reaching their highest levels since 2022, as shipping through the Strait has been severely disrupted. Brent closed above $100 for the first time in four years last week.

A prolonged conflict in the Middle East could impact the semiconductor industry’s access to key materials while rising costs could hit demand for chips that have been central to the artificial intelligence boom, analysts warned.

The U.S.-Israel war with Iran has shone a spotlight on the role countries in the Middle East play in the complex and intricate semiconductor supply chain.

Semiconductor stocks were caught in the sell-off seen in equity markets before President Donald Trump said on Monday that war will end “very soon.”

Memory chipmakers SK Hynix and Samsung have been hit particularly badly with more than $200 billion wiped off their combined value since the start of the war, even with both stocks rallying sharply on Tuesday. The VanEck Semiconductor ETF is down about 3% since the start of the war paring some losses after a 3.6% jump on Monday.

“A prolonged regional conflict could potentially disrupt chipmakers’ manufacturing operations regarding sourcing materials like Helium and Bromine,” Ray Wang, memory analyst at SemiAnalysis, told CNBC.

“For now, the impact appears to be limited. However, a prolonged conflict could eventually lead to disruptions or require adjustments in the sourcing of key materials.”

A South Korean lawmaker warned last week that the Iran war could hamper access to key materials from the Middle East such as helium, Reuters reported. The lawmaker also warned a prolonged conflict could lead to higher energy prices.

So, what exactly is the role of certain countries in the Middle East in the semiconductor supply chain?

Qatar produces over a third of the world’s helium supply, according to the U.S. Geological Survey. Helium is used in the manufacturing process to transfer away heat. It is also used in areas like lithography, which is key for printing the intricate circuitry of a chip. There is no viable alternative to helium.

In 2023, the Semiconductor Industry Association warned that if the supply of helium were to be disrupted, “there would likely be shocks to the global semiconductor manufacturing industry.”

Not only is production an issue. Transportation of the element out of the Middle East could become increasingly difficult with the effective closure of the crucial Strait of Hormuz shipping route.

More than 25% of the world’s helium supply would be taken off the market by an extended shutdown of the Strait of Hormuz, Phil Kornbluth, president of Kornbluth Helium Consulting, told CNBC.

Qatar’s state-owned QatarEnergy produces helium as a byproduct of liquefied natural gas (LNG). QatarEnergy’s Ras Laffan Industrial City was hit by an Iranian drone attack last week, taking the site offline.

Kornbluth said it “is getting hard to imagine” that the world is not looking at a “minimum” two-to-three month shutdown of helium production and a four-to-six month period before the helium supply chain “returns to normal.”

Bromine is another element in focus and is a key part of the semiconductor manufacturing process. Around two-thirds of the world’s bromine production comes from Israel and Jordan, according to the USGS.

“There is modest risk to critical materials. Helium is the main one we are watching. Qatar is one of the largest sources of Helium. Canada and the United States are also large suppliers,” Peter Hanbury, partner in Bain & Company’s Technology practice, told CNBC.

Rising energy costs could also impact the semiconductor industry. That’s because so much of semiconductor demand, from Nvidia‘s graphics processing units to the memory chips products by Samsung and SK Hynix, are designed for data centers that are training and running huge AI models.

Because of the huge demand for AI and the hundreds of billions of dollars being poured by hyperscalers into building infrastructure, the world’s supply of memory chips has been funnelled into these projects. This has created a shortage of memory and an unprecedented price rise of these chips.

Analysts warned on Monday that there was no precedent for the surging price of oil, as the Middle East crisis deepens fears of prolonged production shut-ins and disruption to shipments through the strategically vital Strait of Hormuz.

Oil prices were on track for their biggest-ever jump in a single day on Monday, before significantly paring gains, following a fresh wave of U.S. and Israeli strikes across Iran over the weekend. Oil depots were among the targets.

International benchmark Brent crude futures with May delivery traded 12.8% higher at $104.53 per barrel on Monday morning, while U.S. West Texas Intermediate futures with April delivery were last seen nearly 12% higher at $101.76.

Brent futures had climbed as high as $119.5 per barrel earlier in the trading day, while WTI hit a session high of $119.48.

Neil Atkinson, former head of oil at the International Energy Agency, said the effective closure of the Strait of Hormuz is something energy markets had never seen before. Unless something changes very soon “we are in a potentially game-changing and unprecedented energy crisis,” he told CNBC on Monday.

Countries across the oil-rich Middle East region have started to scale back crude output. Iraq and Kuwait have already begun to shut-in production, with analysts warning that the United Arab Emirates and Saudi Arabia may also be vulnerable if the Strait of Hormuz remains closed for a sustained period.

“Though there are oil stocks around the world, the point is that if this closure of the Strait persists, those oil stocks if they are deployed will be depleted and we are going to be in a situation where, with the oil production actually shut in, in Iraq and possibly in Kuwait and maybe even in time in Saudi Arabia, that we are going to be in a crisis the likes of which we have never seen before,” Atkinson told CNBC’s “Squawk Box Europe.”

Asked what this could mean for oil prices, Atkinson replied: “Sorry, we are getting into the realms of educated guesswork here. I mean, there is no precedent for this. The sky is the limit.”

Typically, about 20% of the world’s oil and gas passes through the Strait of Hormuz, but shipping traffic has all but halted through this key maritime corridor since the war started.

Oil prices came off their session highs on Monday shortly after the Financial Times reported that finance ministers from G7 economies would hold an emergency meeting on Monday to discuss a possible joint release of petroleum from reserves coordinated by the IEA.

The U.K.’s Treasury and French government confirmed to CNBC that the call would take place on Monday.

Tyler Goodspeed, chief economist at ExxonMobil, told CNBC’s “Squawk Box Europe” on Monday that it had been “consensus last week, and to a certain extent still today,” that everyone but Russia had “an interest in normal traffic resuming through the Strait of Hormuz.”

He added the consensus had been that there was “abundant oil on the water and some strategic reserves to cover any short-term gap.” Goodspeed said he was skeptical of this view as the conflict enters its second week.

“When I think of the probability distribution of possible outcomes here, it seems to me there are many more scenarios, and more probable scenarios, in which the strait remains effectively closed harder for longer than there are scenarios in which normal traffic resumes,” Goodspeed said.

Analysts at Societe Generale, meanwhile, warned that prolonged production shut-ins from Middle East countries “materially increase” the risk of restart complications.

“The UAE is likely the next producer at risk of shutting in output, potentially within the next five to seven days,” the analysts said in a research note published Monday.

“Qatar is also vulnerable, though its oil volumes are modest relative to its LNG exposure. Saudi Arabia faces less immediate risk but shut ins would become plausible if the Strait of Hormuz remains closed for a further two to three weeks,” they added.
