The Ormuz Crisis: how it's hitting your investments in real time

Since 28 February 2026 and the joint US-Israeli strikes on Iran, the Revolutionary Guards have declared the Strait of Hormuz closed to "the enemies of Iran". Maritime traffic has fallen 80% in three weeks. Over 150 ships are stalled outside the strait, and their insurers refuse to cover them.

You've already felt the pinch at the pump. But oil is just the tree hiding the forest.

Beyond oil: the 15% that change everything

85% of what transits Hormuz is oil and gas. That's the part everyone talks about. But the remaining 15% is just as critical:

Resource	World share via Hormuz	Impact
Fertilisers (urea, ammonia)	30% of global trade	Food prices +12% expected
Helium	~33% of global production (Qatar)	Semiconductors, medical MRI
Aluminium	9% of global production	Auto, aerospace, construction, packaging

Fertilisers: food inflation in the making

The timing is catastrophic. We're in peak sowing season. Winter wheat needs its second nitrogen feeding right now. Egyptian urea bound for Europe has gone from $487 to $715 per tonne in three weeks — that's +47%.

And Egypt doesn't even depend on Hormuz: it makes its urea from Israeli gas piped overland. But that pipeline has been shut since early March. The Hormuz crisis spreads by ricochet.

If the blockade extends through June, 45 million additional people could fall into food insecurity. — World Food Programme

Fertiliser overcost takes 4 to 6 months to climb the chain: first wheat, then flour, then bread. Increases will hit shelves by autumn 2026.

Helium: the chips at risk

Qatar produces nearly a third of the world's helium. It's a by-product of natural gas extracted at the Ras Laffan complex — the largest LNG plant on the planet. Except Ras Laffan has been shut down since 2 March.

Without helium, semiconductor manufacturing is impossible. Samsung, SK Hynix, TSMC — every major foundry depends on it to cool silicon wafers during etching. No helium, no chip. No chip, no smartphone, no car, no AI server.

Spot helium prices have jumped 70 to 100% in a week. If Qatari production doesn't restart before summer, lead times will start stretching this autumn for anything containing a semiconductor.

Aluminium: the industrial bill

The UAE, Bahrain, Qatar and Saudi Arabia together produce 7 million tonnes of aluminium per year (9% of global output). The London Metal Exchange is up +12% in days, at $3,545 per tonne — a 4-year high.

Auto, aerospace, construction, packaging: these industries will absorb the hike before passing it on to the end consumer.

What the markets are saying

The numbers speak for themselves:

• Brent: +40% since 28 February
• European gas: from 32 to 52 EUR/MWh (nearly doubled)
• Gold: paradoxically -13% in Q1 (strong dollar)
• Bitcoin: -23% in Q1
• LME aluminium: +12%, 4-year high

According to the IMF, every 10% sustained rise in oil prices adds 0.4 points of inflation and costs 0.2 points of growth.

How GeoPulse tracks this crisis

At GeoPulse, we've been monitoring this in real time from day one:

• NLP severity scoring: every Hormuz-related event is analysed by our AI (Claude), which rates severity (0–10), identifies the affected assets, and explains the reasoning
• Predictive signals: 50+ self-adapting rules correlate geopolitical events with market moves
• Truth Table: every prediction is timestamped, immutable, and publicly verifiable — no cherry-picking

The Hormuz crisis is a textbook case for why traditional technical analysis (RSI, MACD, moving averages) falls short in a crisis. When geopolitics takes over, events drive prices — not chart patterns.

What to watch in the coming weeks

1. Short term (now): oil and gas prices, rationing decisions in emerging markets
2. Medium term (summer 2026): Ras Laffan restart in Qatar, helium stocks at foundries
3. Long term (autumn 2026): food prices, semiconductor lead times, eurozone inflation

If the strait reopens quickly, the current shockwave stays manageable. But if Hormuz is still blocked in June, eurozone growth will fall to 0.5% and China will drop below 3%.
