When US and Israeli forces struck Iran two months ago, the conventional expectation was a familiar one: war in the Middle East means oil shocks, panicked investors, and falling stock markets. The reality has been stranger. The world's biggest listed companies have collectively added more than $5.4 trillion in value since the conflict began — a 4.2 per cent gain — even as airlines cut flights, consumers tighten their belts, and executives warn about the war's drag on global business.
The rescue, if it can be called that, has come from two sectors. Chipmakers such as Intel and TSMC, riding a wave of enthusiasm for artificial intelligence, have lifted the broader technology complex. Semiconductor companies worth more than $10bn have collectively risen 26 per cent — roughly $3.7 trillion in added market value — since fighting began in late February. Investors, one strategist explained, are drawn to tech at a time of 'extreme macro uncertainty' because AI earnings feel dependable. Earnings-call data from AlphaSense shows that close to two-thirds of large companies discussed AI this quarter, about twice as many as discussed the Middle East itself.
Energy is the second lifeline. A 50 per cent jump in the oil price has handed enormous gains to producers like Saudi Aramco, PetroChina, and TotalEnergies. Every $1 rise in crude translates into roughly $1bn in additional free cash flow for Aramco alone, which has added $144bn in market value during the war. BP and TotalEnergies are up 14 per cent and 16 per cent respectively, while smaller-footprint producers such as Norway's Equinor have climbed 24 per cent.
But here's the catch: not every oil giant has won. ExxonMobil and Shell both face multibillion-dollar bills to repair damage at Qatar's Ras Laffan industrial city, and disruption in the Strait of Hormuz has pushed shipping costs higher. Exxon's value has fallen 4 per cent — about $28bn — since the conflict began. The same war that printed money for some energy firms has quietly punished others.
The losers list is longer than the headlines suggest. Consumer goods majors such as Procter & Gamble and Kimberly-Clark have warned of price rises as input costs climb. Luxury groups including LVMH and Hermès have struggled with weakening demand, while carmakers face tangled supply chains and dearer aluminium; Nissan, Toyota and Stellantis have all reported sharp drops in Middle East sales. The chief executive of Volvo Cars said his main worry is shifting US consumer sentiment — when workers fear for their jobs, they postpone buying cars or 'anything,' as he put it. Mining companies face a double hit: rising diesel costs and the prospect of slower global growth depressing commodity prices, with gold miners like Agnico Eagle and Zijin Mining among the steepest fallers despite last year's gold rally.
Perhaps the strangest twist is in defence. Despite an actual hot war, the value of leading US and European defence companies has fallen since the Iran conflict began. Governments have been burning through critical munitions stockpiles for years, but analysts say a recent sell-off reflects doubts about whether the industry can actually scale up production fast enough, given persistent supply-chain bottlenecks. The longer trend toward higher defence spending since Russia's invasion of Ukraine in 2022 remains intact — but, for now, AI and oil are doing the heavy lifting in global markets, not weapons.
When missiles started flying between the US, Israel and Iran, global stocks should have cratered. Instead, two unlikely heroes — chipmakers and oil giants — added trillions in value.
Just over two months after US-Israeli strikes on Iran sparked a regional conflict, the world's biggest listed companies have collectively gained more than $5.4 trillion in value — a 4.2 per cent rise. That is the opposite of what usually happens when war breaks out in the Middle East.
The lifeline came from two sectors. Big Tech and chipmakers (think Intel, TSMC) rallied on AI optimism, while oil majors like ExxonMobil, Saudi Aramco and TotalEnergies surged on a 50 per cent jump in crude prices. Airlines, carmakers, luxury brands and miners, meanwhile, are quietly bleeding.
A stock index is not one mood — it's a tug-of-war between sectors pulling in opposite directions. In this war, the rope is being yanked hard by AI and oil:
If you're thinking about college majors, career paths, or where to park a first paycheck, this article is a live demonstration that 'the economy' is never one thing. The same week Volvo's CEO warns workers they could lose their jobs, Nvidia-adjacent engineers are getting signing bonuses. Sector matters more than you think — and AI is currently the gravitational center of global capital.
Two longer arcs are worth watching. First: can AI valuations keep absorbing geopolitical shocks, or is this a bubble waiting for an excuse to pop? Second: European defence stocks have actually fallen since the Iran war started — a clue that investors think governments still can't ramp up weapons production fast enough to matter. If the conflict escalates or the Strait of Hormuz closes, the tug-of-war flips: oil spikes further, but consumer and travel sectors get crushed, and even AI might not save the index.
