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.

Energy Secretary Chris Wright said oil and gas prices will begin to fall when the U.S. begins to knock out Iran’s ability to hinder tanker traffic through the Strait of Hormuz, as Americans weather spiking gas prices due to the war in Iran.

“The plan is to get oil and natural gas and fertilizer and all the products from the Gulf flowing through the straits before too long,” Wright said on Fox News Sunday. “We’re massively attriting their ability to strike with missiles and drones, and that rate of attrition will increase in the coming days. So we’ll be cautious, we’ll be careful, but energy will flow soon.”

President Donald Trump was elected to a second term in the White House in part by promising to lower gas prices and defeat high inflation. He has frequently touted lower gas prices ahead of the November midterm elections, which will determine control of Congress for the remainder of his term.

But gas prices and oil have spiked since the war began in Iran, with vessel bottlenecks in the Strait of Hormuz causing the surge. About 20% of global energy supply moves through the strait.

Gas has jumped to over $3.46 per gallon on average in the U.S., according to GasBuddy. U.S. crude oil has soared to more than $91 per barrel, and the global benchmark Brent crude has spiked to over $92 per barrel.

Wright said that “one large tanker has already gone through the straits with no issues at all.” Typically, roughly 100 tankers and cargo ships move through the strait every day.

Wright said the disruption would last for “weeks, certainly not months.”

“We believe this is a small price to pay to get to a world where energy prices will return back to where they were,” Wright said. “Iran will finally be defanged, and now you can see more investment, more free flow of trade, less ability to threaten energy supplies.”

When asked about potentially tapping the U.S. Strategic Petroleum Reserve to reduce pain at the pump, Wright suggested such a move is not necessary yet. In the past, the SPR has been tapped to mitigate disruptions in oil flows.

“We’re more than happy to use [the SPR] if needed,” Wright said on CBS’s “Face the Nation.” “But … it’s a logistics issue, where do they need oil? They need oil at refineries in Europe and in Asia.”

Trump has also downplayed the option of tapping the SPR.

“We’ve got a lot of oil. Our country has a tremendous amount,” Trump told reporters aboard Air Force One on Saturday. “There’s a lot of oil out there. That’ll get healed very quickly.”

President Donald Trump said in a social media post on Friday that there would be no deal to end the U.S. war against Iran without an “UNCONDITIONAL SURRENDER” by Iran.

The Dow Jones Industrial Average dropped more than 900 points, or nearly 2%, after Trump’s demand, which he wrote on Truth Social. The S&P 500 and Nasdaq Composite fell 1.6% each, and oil futures prices rose.

Trump said that after a surrender and “the selection of a GREAT & ACCEPTABLE Leader(s), we, and many of our wonderful and very brave allies and partners, will work tirelessly to bring Iran back from the brink of destruction, making it economically bigger, better, and stronger than ever before.”

“IRAN WILL HAVE A GREAT FUTURE. “MAKE IRAN GREAT AGAIN (MIGA!)” Trump wrote.

Trump’s demand came as Iran has yet to pick a leader to replace Supreme Leader Ayatollah Ali Khamenei, who was killed last weekend in an airstrike at the beginning of the war by the U.S. and Israel.

White House Press Secretary Karoline Leavitt, when asked by reporters later about potential future leaders of Iran, said, “I know there are a number of people that our intelligence agencies, that the United States government are looking at, but I won’t get any further.”

Trump in June made an identical demand of “UNCONDITIONAL SURRENDER” by Iran in another social media post as he considered launching a military strike against that nation.

The futures price of the global benchmark Brent crude oil rose, breaking $90 per barrel, after Trump posted his latest demand for Iran to surrender without conditions.

Qatar’s energy minister, Saad al-Kaabi, warned Friday that rising oil prices due to the war against Iran “could bring down the economies of the world.”

Al-Kaabi told The Financial Times that crude oil prices could hit as high as $150 per barrel within weeks if tankers cannot pass through the Strait of Hormuz. The last time oil topped $100 a barrel was when Russia invaded Ukraine in 2022.

A prolonged surge in natural gas prices triggered by the ongoing war in the Middle East risks denting European growth and hitting some Asian economies hard, analysts have warned.

Global gas prices have soared this week amid fears of a lengthy disruption to energy flows through the Strait of Hormuz — a key shipping route running between Oman and Iran that handles about one-fifth of global LNG trade — as the Iran conflict escalates.

Dutch Title Transfer Facility (TTF) futures, Europe’s benchmark gas contract, rose 35% on Tuesday to more than 60 euros ($69.64) per megawatt-hour. On the week, prices are around 76% higher.

The Northeast Asia LNG benchmark, the Japan-Korea-Marker (JKM), which captures deliveries to Japan, Korea, China and Taiwan, reached a one-year high, and was last seen around 43 euros per megawatt-hour. U.K. natural gas was also sharply higher.

Qatar, one of the world’s largest LNG producers, halted production on Monday following Iranian drone strikes at Ras Laffan Industrial City and Mesaieed Industrial City. Goldman Sachs estimated the pause will reduce near-term global LNG supply by about 19%.

A senior Iranian Revolutionary Guard official later said the country had closed the Strait of Hormuz to all ships, and warned that any vessel attempting to pass through the channel would be attacked. The U.S., however, said the route remained open, according to a Fox News report.

Europe and much of Asia are more heavily exposed to potential gas price shocks than the U.S., which benefits from both domestic shale and LNG production.

Around 25% of Europe’s total gas supply is LNG, according to Chris Wheaton, oil and gas analyst at Stifel. With roughly 20% of global LNG production sitting behind the Strait, a prolonged disruption could trigger a supply squeeze comparable to the 2022 shock following Russia’s invasion of Ukraine, he said in a note.

“We are much more concerned about European gas prices than we are about oil prices,” Wheaton said.

Shares of Norwegian energy giant Equinor, one of Europe’s largest natural gas suppliers, hit a 52-week high on Tuesday, adding more than 2%, after closing the previous session up more than 8%.

Oil supertanker costs in the Middle East climbed to their highest level on record as conflict between the U.S. and Iran disrupts shipping through the strategically vital Strait of Hormuz.

Major marine war risk providers have started to scrap cover for vessels operating in the Persian Gulf as the fallout from a sudden security shock hobbles key shipping routes in the region.

The benchmark freight rate for Very Large Crude Carriers (VLCCs) — used to ship 2 million barrels of oil from the Middle East to China — hit an all-time high of $423,736 per day on Monday, data from LSEG showed. That marked an increase of more than 94% from Friday’s close.

Alongside a significant jump in oil and gas prices, the stratospheric rise in the cost of hauling crude oil follows the U.S. and Israeli attacks on Iran over the weekend. The expanding conflict has resulted in the effective halt of shipping traffic through the Strait of Hormuz — one of the world’s most important oil choke points, located in the gulf between Oman and Iran.

An Iranian Revolutionary Guards senior official said Monday that the Strait of Hormuz had been closed and warned any vessel attempting to pass through the waterway would be attacked, state media reported. The claim has since been disputed by the U.S. military’s Central Command, CENTCOM, Fox News reported.

“Charterers in the VLCC segment stepped back from the market and avoided securing vessels as multiple incidents have led to increased threat levels around the strait of Hormuz, despite the waterway not being officially closed,” Sheel Bhattacharjee, head of freight pricing in Europe at Argus Media, told CNBC by email.

Oil producers in the Middle East have not yet announced a halt to any production or loading yet, and ports in the UAE, Oman and Kuwait remain operational, Bhattacharjee said, citing market sources.

“But most shipowners were avoiding transits through the strait of Hormuz after insurers cancelled the war risk coverage for vessels in certain areas of the region,” Bhattacharjee said.

It is estimated that roughly one-third of seaborne crude oil trade moves through the strategically important waterway, alongside 19% of global liquefied natural gas (LNG) flows and 14% of global refined products trade, according to Argus Media.

Leading maritime insurers have canceled war risk cover for vessels operating in the Middle East over recent days, amid reports of attacks on multiple ships traversing through the Strait of Hormuz.

Alongside the New York-based American Club, marine insurers including Norway’s Gard and Skuld, Britain’s NorthStandard and the London P&I Club said they were scrapping war risk cover for ships in the region.

Adrian Beciri, CEO of DUCAT Maritime, a Cyprus-based logistics firm specializing in dry bulk, said the knock-on effects of the sprawling Middle East conflict were being felt across the globe.

“We were trying to hire a dry bulk vessel to carry our typical rice food supplies to West Africa, which is around the Cape of Good Hope. You would think that is a million miles away from the conflict zone,” Beciri told CNBC’s “Squawk Box Europe” on Tuesday.

“We actually lost the ship. Someone had paid 50% more than they typically would do to carry coal from Indonesia to the west coast of India. Why did that vessel attract such a high rate? The answer is because the vessel owner was uncertain of getting cargo from the Persian Gulf area,” he continued.

“So, the consequences are far and wide, and this is potentially a double whammy. If we’re looking at the Hormuz closing and the Suez effectively being tampered with by the Houthis, this could be quite significant — much like what we saw during the Covid era and the attacks that were happening there.”

Even if oil tankers are only temporarily blocked from the Strait of Hormuz, it can ratchet up global energy prices, raise shipping costs and create significant supply delays.

The Strait of Hormuz is also key for global container trade. Ports in this region, such as Jebel Ali and Khor Fakkan, are specialized transshipment hubs that serve as intermediary points in global networks.

Shipping giants, including MSC, Maersk, Hapag-Lloyd and CMA CGM, have also issued fresh guidance, seeking to prioritize safety amid a deteriorating security situation.

Oil prices have soared after U.S. and Israeli strikes on Iran continued on Sunday night.

Brent crude prices hit a new 52-week high on Monday, surging 9.3% to reach $79.40, while U.S. West Texas Intermediate prices also rose more than 9% to $73.10.

U.S. President Donald Trump said the “overwhelming military offensive” — which he has dubbed Operation Epic Fury — would continue until the U.S.’s objectives are achieved. Israel launched fresh strikes against both Iran and against Hezbollah targets in Lebanon late on Sunday, which came after Iran attacked military and infrastructure targets across several countries in the region.

As the U.S. continues to target Iranian air defense systems and naval capabilities, global oil supplies have come into sharp focus.

Amrita Sen, founder and director of research at Energy Aspects, told CNBC on Monday that she expects oil prices to likely hold at around $80 level for some time.

Sen said that it is unlikely that the Strait of Hormuz — through which 13-15 million barrels, or 20% of global supply, of oil flows — would be closed altogether. She added that the bigger risk stems from one-off attacks on vessels passing through the area.

Sen said that the U.S. and Israel have the superior military power to ultimately neutralize Iran’s ability to completely shut off the Strait, a key shipping channel for oil producers such as Saudi Arabia, the UAE, Iraq, Iran, and Kuwait.

But single attacks on ships are more difficult to prevent. “This is something we’ve warned right throughout to our clients,” she said.

After three tankers were hit over the weekend, shippers are now being extremely cautious about going in, she added.

“That is the biggest issue right now — how do Asian refiners actually get the volumes from the Middle East?” Sen added.

She noted that Oman and certain UAE grids can bypass the Strait, while Saudi Arabia has contingency plans to move its oil through the East-West pipeline via the Red Sea.

“But even if you are able to move 5 million out through other methods, about 10 is still stuck,” she added.

Sen added that, if energy infrastructure is hit, the price of oil could hit $100.

She added that “the stakes are just too high” when it comes to potential attacks on infrastructure.
