Iran Strike: Market Reaction — Oil at $82, Gas +41%, Stock Market Swings (Analysis and Forecasts)

March 3, 2026. Monday morning began with a cold shower for traders. While Europe and the US rested over the weekend, the Middle East experienced what markets had feared for over a year. The US and Israel launched strikes on Iran, and Tehran responded by threatening to close the Strait of Hormuz — the planet’s main oil artery. Stock indices turned red, Brent crude jumped 13% in hours, touching $82* per barrel, and European gas surged 41%. But the main surprises, it seems, are still ahead.

On Saturday evening, news broke of strikes on Iranian facilities. By Sunday, Tehran did what instantly escalated tensions: tankers in the Strait of Hormuz were given the message — passage is forbidden. Two vessels have already been attacked: one off the coast of Oman, another near the UAE. The International Maritime Organization urged ships to avoid the area. Maersk, the global container shipping giant, announced it was halting transit through the strait and the Suez Canal. Trade froze. Markets simply didn’t know how to react, but Monday morning’s reaction was brutal.

Gas Shock: Qatar Halts Production

But the main blow came from where it was least expected — Qatar. The Guardian reports that state-owned QatarEnergy has halted liquefied natural gas production following attacks on terminals at Ras Laffan and Mesaieed. Qatar’s Defense Ministry confirmed that drones struck an energy facility at Ras Laffan. Fortunately, there were no casualties. But production is at a standstill.

Ras Laffan isn’t just a plant. It’s the heart of the global LNG market. The world’s largest export terminal. Its shutdown could knock nearly a fifth of all liquefied gas supplies off the global market. And this is happening at a time when Europe still remembers the winter of 2022, and storage reserves are depleting faster than usual due to the cold weather.

The market reaction was swift. The Dutch TTF (the benchmark for all of Europe) soared from €32* (equivalent to about $37.50*) to €45* (about $52.70*) per megawatt-hour. Up 41% in a single day. The UK index surged 40%. Jess Ralston from the Energy and Climate Intelligence Unit has already called it a “wake-up call”: energy bills for households and businesses are set to creep up again.

Oil: Brent Breaks Through the Ceiling

It’s the same story with oil. Brent spiked 13% at one point, touching $82* per barrel — a 14-month high. By Monday evening, the frenzy had subsided slightly, but quotes remained 6% above Friday’s levels, around $77*.

Why such an acute reaction? The figures speak for themselves: roughly a fifth of the world’s oil and almost all seaborne liquefied gas passes through the Strait of Hormuz. If the strait is de facto closed (even without official announcements), tankers don’t sail, insurers refuse coverage, and traders panic.

Analysts at Wood Mackenzie are sounding the alarm: we’re facing a double shock — not only is current exports halted, but access to OPEC+’s spare capacity (all located in the region) is effectively blocked. If the situation drags on, triple-digit oil prices — $100* and above — could become a reality by summer.

Stock Markets: Red Across the Globe

Investors hate uncertainty. And a war in the Middle East involving a nuclear power is the epitome of uncertainty. European indices plummeted: Germany’s Dax lost 2.4%, France’s CAC 40 fell 2.2%, Italy’s FTSE MIB dropped 2%, and Spain’s Ibex slid 2.6%. The UK’s FTSE 100 fell by a more modest 1.2%, cushioned by soaring shares of oil giants BP and Shell (up 3% each).

Asia is also in the red: Japan’s Nikkei 225 shed nearly 2.4%, while China’s Shenzhen Composite fell 0.7%. Australia’s ASX 200 opened with a sharp drop but managed to recoup losses by the close.

Airlines fared the worst: IAG (owner of British Airways) plunged 6%, easyJet fell 4%. Thousands of flights have been canceled or rescheduled due to the closure of airspace over the conflict zone and skyrocketing fuel prices.

The defense sector, as usual, is thriving: BAE Systems gained 5%. War is a profitable time for defense stocks — it’s an axiom.

Wall Street opened lower, but indices stabilized slightly by Monday evening. Investors are bewildered; no one knows how long the conflict will last. Donald Trump hinted that the operation could take another four weeks until objectives are fully met. For markets, the phrase “four weeks of war with Iran” sounds like a death sentence.

Gold and Safe Havens

In this turmoil, investors have traditionally fled to safe-haven assets. Gold rose 2.5% to $2908* per ounce (based on Monday evening data; at one point the price touched $2950). The dollar strengthened against most currencies. The Japanese yen also found support as a risk refuge.

But the main question nagging markets is: how long will this last? If the conflict escalates into a full-scale war involving Iran and its proxies across the region, energy prices could go stratospheric. And that would be a direct path to a global recession.

What This Means for American and European Consumers

For the average American filling up their tank or the European paying for heating, the news is bad. Gas prices in the US had already been fluctuating due to seasonal factors and refinery maintenance. Now, the oil and gas factor will compound this.

Analysts predict: if Brent holds above $80, a gallon of gasoline in the US could rise by roughly 5-10 cents. If it moves toward $90, add another 10-15 cents. At $100, gasoline could become 20-25 cents more expensive per gallon. In the UK, where petrol prices recently hovered around £1.45 per liter, a move to $100 oil could add 10-12 pence per liter.

For European industry, the situation is even more acute. Europe remains dependent on imported LNG, and the loss of Qatari gas (even temporarily) will hit household wallets and business bottom lines. Energy-intensive industries (chemicals, metals, cement) will again come under severe pressure. We may see temporary plant shutdowns, reminiscent of 2022, but for different reasons.

For US consumers, who are less dependent on imported LNG but still subject to global oil prices, the impact will be felt primarily at the pump. The Biden administration (or the incoming administration depending on election outcomes) may face renewed pressure to tap the Strategic Petroleum Reserve to moderate price spikes.

What to Expect Next

The coming days will reveal how severe the damage to Qatari terminals is and how quickly they can be restored. Just as crucial is whether Iran will officially blockade the Strait of Hormuz or limit itself to “warnings” and targeted strikes on vessels.

For now, markets are pricing in the worst-case scenario. If the conflict does not expand and the strait remains open to tankers (albeit with heightened risks), prices could correct downward. But if the war drags on or draws in other players (primarily Saudi Arabia or the UAE), we could be looking at a repeat of the 2022 energy crisis — or potentially worse.

One thing is certain: March 3, 2026, will go down in history as the day markets finally realized that a war in the Middle East is not a local conflict. It’s a tectonic shift for the global economy with utterly unpredictable consequences.
