The short answer: the US-Israel war on Iran has effectively closed the Strait of Hormuz — the narrow waterway through which 20% of the world’s daily oil supply flows. When Iran threatened to attack tankers transiting the strait, shipping operators did what any rational person does when told there are ballistic missiles nearby: they left.

With tankers gone, Gulf producers like Iraq, Kuwait and the UAE couldn’t export their oil. With nowhere to ship it and storage tanks filling up, they started cutting production. Iraq’s three main southern oilfields — which normally pump 4.3 million barrels per day — fell 70% to just 1.3 million bpd. Simultaneously, Israel struck Iranian oil storage facilities over the weekend, and Iran retaliated against Bahrain’s desalination plants. The market, which had politely been pretending this wouldn’t get worse, decided it probably would get worse. Hence: $113 oil and a 1,000-point Dow futures crash before 9 AM on a Monday.

The Strait of Hormuz is a narrow channel — at its narrowest, just 21 miles wide — sitting between Iran and Oman. Every day, roughly 20 million barrels of crude oil pass through it, along with massive volumes of liquefied natural gas. It connects the Persian Gulf (where Saudi Arabia, Iraq, Kuwait, UAE and Iran all export from) to the wider ocean and the rest of the world.

Think of it as the world’s most important energy highway. Now imagine someone put spike strips across it and is threatening to blow up any vehicle that uses it. That’s the Strait of Hormuz in March 2026. The roughly 200 tankers currently stranded in the Gulf represent tens of millions of barrels of oil that should be en route to refineries in Asia, Europe and the US — and aren’t. Every day they stay stuck, the global supply picture gets worse.

Kpler’s lead crude analyst and Qatar’s Energy Minister have both floated $150/barrel as a possibility if the Strait remains closed through end-March. That’s not a certainty — but it’s no longer the kind of number that makes analysts laugh nervously and change the subject.

Here’s what $150 oil would look like in practice:

🚗 US gas prices: National average would likely climb toward $4.80–5.20/gallon (it was $3.45 on Sunday, already up 16% in a week).
✈️ Flights: Jet fuel costs would surge; expect airfare increases within weeks.
🛒 Groceries: Transport and logistics costs would filter through to food prices within 4–8 weeks.
📈 Inflation: Every $20 rise in crude adds ~0.4pp to US CPI. A $40 sustained rise above current levels could push headline inflation back above 3%.
🏦 Interest rates: The Fed, already frozen between a weak job market and sticky inflation, would have even less room to cut rates.

The G7 coordinated strategic reserve release is designed to prevent this scenario. Whether it’s enough depends entirely on how long the Strait stays closed.

This is the Fed’s nightmare scenario, and it’s genuinely not their fault. The Federal Reserve has two jobs: keep inflation around 2%, and keep unemployment low. Right now, those two jobs are pulling in opposite directions at full force, and an oil shock is making both worse simultaneously.

The US economy just shed 92,000 jobs in February — the third monthly job loss in five months. That’s the kind of number that normally screams “cut rates immediately.” But cutting rates when oil prices are surging risks pouring petrol on an already-hot inflation fire (pun very much intended). Core PCE is already at 3.0%, a full percentage point above target. An oil-driven CPI surge on top of that could push headline inflation meaningfully higher.

So the Fed’s options are: cut rates and risk inflation, hold rates and watch the economy slow, or raise rates and cause a recession. Morgan Stanley describes this as the Fed being “boxed in.” We’d describe it as being stuck in a revolving door that’s on fire. Their current approach: “wait and see.” Which is a very professional way of saying they’re watching the same news as everyone else and hoping something changes.

Strategic Petroleum Reserves (SPR) are emergency oil stockpiles held by governments for exactly this kind of crisis. The US alone holds around 400 million barrels in underground salt caverns in Louisiana and Texas. The G7 — US, UK, Germany, France, Italy, Japan, Canada — collectively control significant reserves, and the IEA (International Energy Agency) coordinates member countries’ reserves on top of that.

The last major coordinated SPR release was after Russia invaded Ukraine in 2022, when the IEA released 60 million barrels. It provided temporary price relief. The key word is temporary.

Today’s news of a G7 emergency call pushed oil back from its $119.50 intraday peak to around $108–114 — a meaningful pullback, but it underscores the problem: the market barely blinked. An SPR release puts more oil into the system, but it does nothing to fix the underlying issue, which is that 20% of global oil supply is physically stuck in the Persian Gulf behind a wall of Iranian missile threats. Until tankers can safely transit the Strait of Hormuz again, reserve releases buy time rather than solve the problem.

📈 Energy stocks (domestic US producers): Companies with US-based production are insulated from Hormuz disruptions. Higher crude prices directly boost their revenues and margins. In a $110+ environment, this is the most straightforward beneficiary.

🛡️ Defence sector: Palantir jumped 15% last week. Lockheed Martin, Raytheon, Northrop Grumman are already in a multi-year government spending supercycle. Trump confirmed defence CEOs have agreed to quadruple “Exquisite Class” weapon production. Wars are expensive; defence companies’ order books grow accordingly.

🥇 Gold: Up 7.7% since the war began on Feb 28. With the Fed on hold, geopolitical uncertainty high, and real yields uncertain, gold’s role as a crisis hedge is doing exactly what it says on the tin.

⚠️ Caution — Broad equities: VIX at 34.78 signals elevated fear. The S&P’s relative calm last week was the grace period. Monday’s futures suggest the reassessment has begun. Volatility is now the baseline, not the exception.

⚠️ Caution — Long-duration bonds: Rising inflation expectations push yields higher, hurting bond prices. The 10-year Treasury yield climbed 6.6bps to 4.13% Monday. If oil stays elevated, the rate-cut narrative that was supporting bonds in early 2026 gets significantly complicated.

On March 8, Trump posted on Truth Social: “Short term oil prices, which will drop rapidly when the destruction of the Iran nuclear threat is over, is a very small price to pay for U.S.A., and World, Safety and Peace. ONLY FOOLS WOULD THINK DIFFERENTLY!”

The geopolitical argument has merit: if the war achieves its stated objectives and the Strait reopens within weeks, the oil spike would prove temporary and the economic damage manageable. History supports the idea that commodity shocks tied to short conflicts resolve relatively quickly.

The problem is the “short” part. The administration’s own timeline has slipped from “a few days” to “4-5 weeks” to Defence Secretary Hegseth’s memorable “3, 6, 8 weeks — whatever.” Iran has now named a hardline new Supreme Leader with IRGC backing who has pledged to fight on. The Strait remains closed. The US just ordered diplomats out of Saudi Arabia.

The bond market (yields up), the VIX (up 18%), the Dow futures (-1,011 points), and the 92,000 Americans who lost their jobs in February would respectfully suggest the price — small or otherwise — is being felt right now, regardless of how it looks in hindsight.
