The tanker sat at the horizon like a parked thought—no horns, no fuel, just a flat line on the news feed. I watched traders blink at their screens as prices leapt and a familiar calm in the markets evaporated. You can feel the map of global supply re-writing itself in real time.
I’ve followed markets for years, and I’m telling you: the World Trade Organization’s warning isn’t abstract. Robert Staiger, the WTO’s chief economist, says a sustained energy shock could shave world growth from a baseline of 2.8% in 2026 to 2.5% before a projected recovery in 2027. That shift looks small on paper. In practice it changes which projects get funded, which jobs get created, and which technologies survive their infancy.
Ships are stalled in the Strait of Hormuz. The blockage is not a fleeting headline but the hinge of a shock that spreads through energy, food, and tech.
Roughly 20% of the world’s oil flows through that narrow choke point. With Iran shooting missiles and drones at shipping, the corridor has effectively been shut down. The immediate result: panic buying and price spikes. Brent crude briefly hit $119 (€109) a barrel before settling around $111 (€102). Gasoline at U.S. pumps averages $3.88 (€3.57) a gallon now, up from $2.90 (€2.67) before the war.
How will higher oil prices affect AI investment?
You should care because AI isn’t a small corner of the market—it’s a capital-hungry engine. The AI investment boom propped global growth last year through massive spending on GPUs, data centers, and cloud compute. But Staiger warned investors: if energy prices remain elevated, that boom will lose steam. Why? AI spending is concentrated in a handful of hyperscalers—Nvidia, Microsoft (Azure), Google Cloud, Amazon Web Services—whose capital allocation decisions ripple through the industry. When operational costs for training models and cooling data centers rise, CFOs start delaying multibillion-dollar projects.
Gas pumps and grocery aisles are getting meaner price tags. That shows how energy shocks move from port to plate.
The war hasn’t just nudged oil. Israel’s strike on Iran’s South Pars gas field and Iran’s retaliatory hit on Qatar’s Ras Laffan—the world’s largest LNG complex—sent European natural-gas prices up roughly 30% in a single session, after increases of 60–70% since the conflict began. Europe and parts of Asia depend on Middle Eastern gas; an extended outage bites into fertilizer supply and food prices, which slows real wages and consumer demand.
Bessent: “We unsanctioned Russian oil … in the coming days, we may unsanction the Iranian oil that’s on the water”

Washington is trying makeshift fixes while the market votes with its wallet. That mismatch explains why you see policy noise and few reliable remedies.
Scott Bessent signaled on Fox Business that the U.S. might ease sanctions on oil that’s already on the water—an ad-hoc attempt at stabilizing supply. The White House, according to Axios, is not pursuing crude export limits. Military analysts say reopening the Strait of Hormuz may require U.S. boots on the ground; Reuters reported the administration weighing reinforcements. The Pentagon has spent an estimated $16 billion (€15 billion) so far and may request another $200 billion (€184 billion) to fund operations and contingency plans.
Will oil prices slow global GDP growth?
The WTO’s math is blunt: sustained high energy prices shave growth by a few tenths of a percent—enough to freeze investment decisions and slow hiring in sensitive sectors. For AI, where billions of dollars of planned capital expenditures are at stake, that freeze can cascade. Investors reprice risk, VCs hold checks, and boardrooms ask whether training a gargantuan model this quarter makes sense if energy costs double operational expenses.
Markets are jittery and large tech firms are watching their cost curves. That everyday volatility shows how fragile an investment cycle can be.
The oil shock is a fever running through markets; when energy costs spike, long-term, power-hungry projects get deferred. AI is a skyscraper built on quicksand—huge potential, but sensitive to a shock that raises the price of compute, data center cooling, and cloud availability. If Nvidia’s GPUs become more expensive to run and Azure, Google Cloud, and AWS pass through higher electricity costs, startups and labs lose runway.
Beyond tech, fertilizer costs rise with natural-gas spikes because ammonia production is energy intensive. That feeds into food inflation and reduced purchasing power—another channel by which energy shocks slow GDP.
I won’t pretend we have a tidy solution here. You can track headlines—Reuters on reinforcements, the Financial Times on damage at Ras Laffan, the New York Times and Wall Street Journal on market moves—but the practical reality is this: unless the Strait reopens or supply is replaced, prices will keep pressuring budgets, balance sheets, and bold experiments in AI. So ask yourself: if the world’s largest tech firms pull in their horns and governments funnel billions to military options, who pays the bill for innovation—and at what cost to the global economy?
