Brent crude oil prices reached $110 a barrel on Wednesday afternoon, after Iranian state media reported that part of the South Pars gas field, the largest plant in Iran, and the Asaluyeh oil facility were struck by Israel.

Moreover, the US oil benchmark WTI also rose and is trading at $98 a barrel at the time of writing.

In response to the latest Israeli attacks, the IRGC announced that some Gulf energy sites are once again “legitimate targets”.

The prospect of escalation and prolongation of the conflict in the Middle East, resulting in further destruction of energy infrastructure, and consequently disruption to global markets, has sent oil prices higher once again.

The climb occurs despite other positive news that would normally have a dampening effect on energy markets.

Saudi Arabia confirmed on Wednesday that its biggest oil refinery, Ras Tanura, restarted operations on 13 March.

Additionally, the Trump administration officially announced a 60-day waiver of the Jones Act, a century-old maritime law that restricts the movement of cargo between US ports to vessels that are American-built, American-owned, American-flagged and crewed.

However, in the face of increased tensions and more attacks on oil infrastructure, these potentially mitigating developments have not had any effect in taming prices.

Trump administration confirms Jones Act waiver

The White House Press Secretary, Karoline Leavitt, confirmed the Trump administration’s decision to issue a 60-day waiver of the Jones Act.

The measure lifts the restriction on the movement of cargo between US ports, allowing foreign tankers temporarily and cheaply to transport vital resources such as oil, gas and fertilisers along the US coastline.

In a post on X on Wednesday, Leavitt explained that the decision is “just another step to mitigate the short-term disruptions to the oil market as the US military continues meeting the objectives of Operation Epic Fury.”

The last Jones Act waiver was issued in October 2022 for a tanker supplying Puerto Rico after Hurricane Fiona.

Before that, the Biden administration temporarily eased the law in 2021 for refiner Valero Energy, after a cyberattack crippled a major East Coast fuel pipeline.

Trump renews pressure on allies to secure the Strait of Hormuz

In a separate development, US President Donald Trump has renewed pressure on allies to join a naval escort mission in order to secure the Strait of Hormuz and normalise the circulation of vessels in the region.

In a post on Truth Social, President Trump argued that allied countries need to use the Strait of Hormuz while the US does not, and warned that they could be left managing it on their own in the aftermath of the war.

Since President Trump’s original request, no firm commitments have emerged, but on Monday, the Wall Street Journal reported that the White House plans to announce as early as this week that multiple countries have agreed to join the escort mission.

The report also stated that officials are still deliberating whether such an operation would start before or after the war ends.

After meeting in Brussels, EU foreign ministers discussed extending the bloc’s Aspides naval mission to the Strait of Hormuz, but ultimately declined to participate.

Eighteen days into the war in Iran, and the scorecard for global equity markets makes for uncomfortable reading.

European benchmark indices have shed around 7% since hostilities began — the Euro STOXX 50 down 6.5%, Germany’s DAX off 7%, France’s CAC 40 down 7.2%, and Italy’s FTSE MIB lower by 6.4% — dwarfing the more modest 2.5% decline in the US S&P 500, which benefits from America’s status as the world’s largest oil producer and its relative insulation from the energy shock.

Yet the headline numbers tell only half the story.

Beneath the surface, an extraordinary divide has opened up — between European companies that thrive on expensive energy, and those being crushed by it.

The energy shock reshaping the continent

The conflict’s most immediate economic consequence has been a seismic repricing of energy.

Iran’s effective closure of the Strait of Hormuz — through which 20% of the world’s petroleum flows — caused Brent crude to surge from around $70 to nearly $120 per barrel within days.

As of Tuesday, Brent sits at approximately $105, a 42% rally from pre-war levels.

In an attempt to cap the oil price surge, the International Energy Agency coordinated a historic intervention.

More than 30 nations in Europe, North America, and northeast Asia agreed to release a combined 400 million barrels of oil from emergency reserves — the largest such action in the IEA’s 50-year history.

Yet the oil market has sent a clear signal that even this enormous release is nowhere near enough to address the unprecedented supply disruption, with crude prices surging more than 17% since the announcement.

Natural gas has been hit even harder. The Dutch TTF benchmark — Europe’s most important gas price reference — has surged 60% to €52 per megawatt-hour.

In a note this week, Goldman Sachs energy analyst Samantha Dart warned this week that approximately 80 million tonnes per annum of LNG supply — 19% of the global total — is currently offline following the Strait’s disruption and the shutdown of Qatar’s LNG production facilities.

Her team maintains a TTF forecast of €63/MWh for the second quarter of 2026, warning that tightening European physical balances could push prices into the gas-to-oil switching range before the conflict resolves.

The winners: Energy, renewables and fertilizer

The clearest beneficiaries have been European oil and gas producers, whose revenues move in lockstep with the commodity the war has repriced so dramatically.

Norwegian energy giant Equinor has surged 23.7% since the start of the month, as investors pile into one of the continent’s largest oil and gas producers with substantial assets well outside the conflict zone.

Fellow Norwegian producer Vår Energi is up 19.9%, while Aker BP has gained 17.1%. Italy’s Eni is up 14.7%, and Portugal’s Galp Energia has added 13.6%.

The most striking gains, however, have come from an unexpected corner: biofuels.

German renewable fuels producer Verbio SE has shot up 30.4%, and Finland’s Neste Oyj — the world’s largest producer of renewable diesel — has gained 28.1%.

As conventional fossil fuels become more expensive and supply chains more precarious, energy alternatives become dramatically more attractive to both buyers and investors.

German gas utility Uniper SE, which has spent recent years diversifying away from Russian supply, has rallied 19.1%.

The fertiliser sector has also attracted significant gains, with K+S rising 15.3% and Yara International rising 15.0%.

The moves reflect a commodity supply crisis hiding in plain sight: around one third of global seaborne fertiliser trade — roughly 16 million tonnes — passes through the Strait of Hormuz, including 43% of seaborne urea exports, 44% of sulphur, and over a quarter of traded ammonia.

The losers: Steel, airlines and construction

On the other side of the ledger, the losses have been equally dramatic. Energy-intensive industries and businesses exposed to higher costs with little pricing power have been savaged.

Airlines have taken some of the heaviest punishment. Wizz Air — the Budapest-based low-cost carrier with heavy exposure to Central and Eastern European routes — has collapsed 31.2%.

Air France-KLM has lost 22.1% and easyJet has dropped 21.8%. All three face the same brutal arithmetic: jet fuel costs have surged, hedging programmes offer only partial and temporary protection, and there is limited ability to pass costs on to passengers quickly enough to protect earnings.

Steel producers have been hit with similar force. Salzgitter has fallen 27.9%, thyssenkrupp is down 27.3%, and ArcelorMittal has shed 19.1%, joined by stainless steel specialist Aperam, which has dropped 24.5%.

Steel production ranks among the most energy-intensive industrial processes on earth, and mills operating on thin margins face an immediate profitability crisis when gas prices surge 60% in such a short period.

Spanish engineering contractor Técnicas Reunidas has dropped 23.7%, a casualty of its deep exposure to Middle Eastern energy infrastructure projects now thrown into uncertainty by the conflict.

Construction group Webuild has fallen 26.6%, reflecting broader fears that an energy-driven slowdown will freeze infrastructure investment across Europe’s most exposed economies.

Mining company Hochschild rounds out the list, down 21%, rising energy costs compress margins and risk appetite for smaller extractive names evaporates.

Europe enters this crisis in a structurally vulnerable position.

Despite having dramatically reduced its dependence on Russian pipeline gas since the invasion of Ukraine, the continent remains acutely sensitive to energy supply disruptions — and gas storage levels heading into 2026 offer less of a buffer than in prior years.

The global energy landscape is facing its most volatile period in decades following the US-Israeli strikes against Iran on 28 February that triggered a wider and potentially prolonged conflict in the Middle East.

What began as a targeted military operation has rapidly escalated into a direct confrontation with global economic implications.

Based on claims by Iranian state media and regional reports, the Islamic Revolutionary Guard Corps (IRGC) has ostensibly adopted a strategy of “energy blackmail” to leverage the international community into pressuring the US and Israel to cease its attacks.

The $200 per oil barrel threat was first articulated shortly after the conflict began.

On Sunday 1 March, a senior IRGC spokesperson warned that if “cowardly anti-human actions” continued, the world should prepare for a massive price surge, even as high as $200 per oil barrel.

This rhetoric has since become a central pillar of Tehran’s messaging.

As recently as this Wednesday, Ebrahim Zolfaqari, the spokesperson for Iran’s Khatam al-Anbiya military command headquarters, told state media: “Get ready for the oil barrel to be at $200, because the oil price depends on the regional security which you have destabilised.”

Iran’s tactical disruption

The IRGC’s current strategy relies on “internationalising” the cost of the conflict.

By disrupting the flow of nearly 20% of the world’s oil and liquefied natural gas (LNG) through the Strait of Hormuz, Iran aims to drag the global economy into the fray.

This is why the IRGC has targeted vessels from neutral nations, including ships sailing under Thai, Japanese and Marshall Islands flags, among others.

According to energy analysts, this disruption is designed to create domestic political pressure within Western nations, to in turn force the US and Israel to pull back on military action in exchange for energy stability.

By striking countries that have not attacked them directly, Tehran is signaling that no maritime trade is safe as long as the strikes on its soil continue.

The main vector of this strategy is precisely the disruption of energy markets, an element Iran can influence directly through its geographical advantage.

A history of oil price shocks

While $200 per barrel sounds astronomical, oil has approached similar levels in the past when adjusted for inflation.

The highest nominal price ever recorded was around $147 in 2008, driven by peak oil fears and rampant speculation just before the global financial crisis. When adjusted for 2026 inflation, that 2008 peak represents roughly $211 per barrel.

Previous major shocks, such as the 1973-74 Arab Oil Embargo and the 1979 Iranian Revolution, saw prices quadruple and double respectively from pre-crisis levels.

In 1980, prices hit a nominal peak of about $39.50, which would be approximately $160 in today’s terms.

However, the current crisis involves a total physical blockade of one of the world’s most critical maritime chokepoint, increasing the risk of a price “moonshot”.

Market response and reserves

At the time of writing, Brent crude is trading just above $100 per barrel, a sharp increase from the $60 range seen in mid-February before the Iran war began.

The International Energy Agency has attempted to stabilise the market by orchestrating the largest-ever coordinated release of strategic reserves, but the continuation of Iranian strikes agaisnt oil infrastructure and tankers has largely neutralised the effort.

With insurance providers cancelling war-risk coverage and shipping companies redirecting fleets, the market remains in a state of high anxiety.

If the blockade on the Strait of Hormuz persists, the $200 figure may shift from a political threat to an increasingly likely scenario.

In a recent report, Oxford Economics identified $140 per barrel as the threshold at which the global economy tips into mild recession, reducing world GDP by 0.7% by year-end and pushing the UK, the Eurozone and Japan into contraction.

Brent futures rose sharply on Thursday, spiking above $100 before easing slightly but remaining higher than levels seen earlier in the week as markets stay incredibly volatile.

This comes despite an unprecedented decision by the 32-member International Energy Agency (IEA) on Wednesday to release a record 400 million barrels to calm markets, more than double the volume released after Russia’s 2022 invasion of Ukraine.

Following the IEA decision, Iran stepped up its offensive campaign and launched strikes on Omani oil storage facilities at the Salalah port and multiple ships in and near the Strait of Hormuz, sending prices higher again.

Record coordinated release of reserves

The US alone is contributing 172 million barrels. Germany, France and Italy also confirmed they would tap their stocks, while Japan said it would begin releases next Monday.

IEA executive director Fatih Birol described the current Iran-related crisis as an “oil market challenge unprecedented in scale”, adding that the collective response reflected “strong solidarity” in defence of global energy security.

Exports of crude and refined products from the region have dropped to 10-15% of pre-war levels, with the Strait of Hormuz, which normally carries one-fifth of the world’s oil, effectively closed to the large majority of tankers.

Iran’s attacks blunt expected price relief

The new Iranian strikes came at lightning speed, directly after the IEA announcement.

Drones targeted fuel storage tanks and silos at Oman’s Salalah port, igniting fires that Omani authorities were still working to contain late on Wednesday.

British maritime security firm Ambrey confirmed damage to the facilities, while Danish shipping giant Maersk temporarily halted port operations.

Omani officials stressed there had been “no disruption to the continuity of oil supplies or petroleum derivatives” inside the country itself, while Iranian state media reported that President Pezeshkian had assured Oman’s sultan the incident would be investigated.

At the same time, six vessels were struck in the Gulf and Strait of Hormuz.

Among the reports, there was confirmation of a projectile hitting a container ship near the UAE and strikes on two tankers in Iraqi waters.

UK Maritime Trade Operations, and other monitoring groups, attributed the incidents to Iranian forces or proxies.

These developments, occurring the very day of the reserves release, appear to have smothered the anticipated calming effect on prices.

As of Thursday, the number of ships struck in the region since the beginning of the conflict rose to at least sixteen.

Record release may signal deeper market concerns

Some analysts note that the sheer volume of the release could itself be interpreted negatively. Previous coordinated actions never exceeded 183 million barrels.

The scale of the release suggests importing nations already view the disruption as the most severe and long-lasting in decades.

Even worse, a record release may not be enough.

Speaking to Euronews, Warren Patterson, Head of Commodities Strategy at ING, was blunt in his assessment.

“A record 400 million barrel release from emergency reserves is helpful, but it’s not going to go very far to offset the roughly 15 million daily supply currently disrupted.”

Patterson also added that “the only solution that will bring oil prices down on a sustained basis is getting oil flowing through the Strait of Hormuz again.”

Oxford Economics echoes this concern, warning that “the economic effect of higher energy costs rises as the oil price increases,” in a report that seemingly indicates the crisis is far from over and we have yet to feel the compounding effect of the initial shock.

Russian sanctions relief remains off the table

With the reserve release failing to calm prices, attention has turned to Russian oil as a potential source of additional supply.

The US Treasury last week granted Indian refiners a 30-day waiver to purchase Russian crude from vessels already stranded at sea, though the measure expires on 4 April and deliberately excludes new shipments.

Following the G7 emergency discussions on Wednesday, French President Emmanuel Macron stated that the group had agreed “the situation does not justify lifting any sanctions” on Russia, emphasising the need to increase global production instead.

The contrast between Washington’s narrow waiver and the G7’s firm collective position leaves little prospect of sanctions relief acting as a meaningful pressure valve, a view shared by analysts.

“Any sanction relief for Russia would see some marginal supply increases, but again not enough, with Russia’s oil output having held up well in recent years despite sanctions,” Warren Patterson of ING told Euronews.

$140-$150 oil barrel possible if conflict is prolonged

Should tensions persist, analysts warn prices could climb substantially higher.

Oxford Economics identifies $140 per barrel as the threshold at which the global economy tips into mild recession, reducing world GDP by 0.7% by year-end and pushing the UK, the Eurozone and Japan into contraction.

The managing director of the IMF, Kristalina Georgieva, also stated that every 10% increase in oil prices, provided they persist for most of the year, will push up global inflation by 0.4% and reduce worldwide economic output by as much as 0.2%.

“The risk is stark,” Patterson warned. “It’s only a matter of time before we see oil prices hitting fresh record highs if the conflict is not swiftly and decisively resolved.”

The IEA’s intervention has provided a temporary buffer, but with little visible impact on prices.

The benchmark European gas price, traded on the Dutch TTF hub, rose by as much as 45% to around €46 per megawatt-hour in early afternoon trading.

UK natural gas prices also surged, with the NBP benchmark climbing sharply in tandem with continental markets.

High market volatility has driven sharp minute-by-minute swings.

The sharp increase follows US and Israeli strikes on Iran, which have heightened tensions in a region critical to global energy flows.

QatarEnergy announced early Monday afternoon that it had halted liquefied natural gas production linked to the giant North Field gas reservoir following an attack on its facilities, but gave no further details as to the extent of the impact on operations.

Strait of Hormuz disruption raises global concerns

A large proportion of the world’s energy supply comes from the Middle East, and before the announcement from Qatar, the seaborne oil and gas transport was at the centre of market fears.

The Strait of Hormuz, a narrow maritime passage largely controlled by Iran, is one of the world’s most important energy chokepoints for oil and LNG, including exports from Qatar.

Iran has moved to block traffic through the strait following the strikes, raising concerns about supply interruptions.

“In modern history, the Strait of Hormuz has never been actually closed, albeit a temporary slowing of traffic has occurred,” said Maurizio Carulli, global energy analyst at Quilter Cheviot.

He added that “about 20% of global oil supply transits through the Strait of Hormuz and 38% of seaborne crude oil trade.”

Carulli does not expect oil shipping companies to send through their vessels until “the military situation de-escalates”, due to the risk of ship damage or seizures, as well as temporary unavailability of insurance cover.

“Satellite data shows that oil tanker transit had virtually halted over the weekend, a precautionary measure by shipping companies,” he added.

Any sustained disruption could affect LNG shipments from Qatar, which supplies around 12% to 14% of Europe’s LNG imports.

Europe exposed to global competition

While Europe does not rely primarily on Qatari gas, analysts say the indirect impact could still be significant.

If supplies to Asia are disrupted, buyers there may seek alternative cargoes, increasing global competition for LNG.

This would likely push prices higher worldwide, including in Europe.

Qatar, the world’s third-largest LNG exporter after the United States and Australia, has become an increasingly important supplier to Europe since Russia’s invasion of Ukraine in 2022 forced European countries to reduce their dependence on Russian pipeline gas.

Low storage levels increase vulnerability

Europe’s relatively low gas storage levels have added to market anxiety.

Storage across the European Union is currently below 30% capacity as the winter heating season draws to a close, compared with around 40% at the same point last year.

Germany and France, the bloc’s two largest economies, are among the most vulnerable.

Germany’s gas storage facilities were 20.5% full as of Saturday, while France’s stood at 21%, according to data from Gas Infrastructure Europe.

Lower reserves leave countries more vulnerable to supply disruptions and price volatility, particularly if global LNG markets tighten further.
