Strait That Shook the World

A chokepoint that controls a fifth of the world's oil

When U.S. and Israeli forces launched military operations against Iran on February 28, 2026, few expected the fallout to escalate this far. Three months on, the Strait of Hormuz — the narrow waterway connecting the Persian Gulf to the open ocean — remains effectively blockaded, with tanker traffic running at barely 10% of pre-war levels. The consequences for global energy markets have been seismic.

The Strait of Hormuz is not merely a shipping lane. It is the artey through which roughly 20% of the world's oil and 25% of its liquefied natural gas flow every single day. The IEA has called the situation the "greatest global energy security challenge in history." That is not hyperbole — it is arithmetic.

"The most important solution to the energy shock caused by the Iran war would be the Strait of Hormuz's full and unconditional reopening."

Since hostilities began, Iran's blockade has resulted in the effective loss of nearly a billion barrels of cumulative oil supply, with the shortage deepening every day the sea lane remains closed. Saudi Arabia, the UAE, and Iraq — all major exporters — hold spare capacity on paper, but those barrels still need to transit Hormuz to reach the market. When the strait itself is the bottleneck, spare capacity provides little relief.

Price History

From $72 to $138 — and where we stand now

The oil price journey since the war began has been one of historic volatility, shaped by each diplomatic twist and military escalation. Here is how Brent crude has moved:

Pre-war · Feb 27

Pre-conflict baseline

War begins · Mar 2

+8% in 48 hours

Hormuz closes · Mar

Breaks triple digits

All-time high

Deal hopes · May 20

−5% on diplomacy

Today · May 27

Stalemate premium

The price swings reflect a market caught between two forces: the structural reality of constrained supply, and the hope — repeatedly dashed — of a diplomatic breakthrough. Every time Trump signals openness to talks, Brent drops. Every time negotiations collapse over Iran's demands regarding its uranium stockpile or proposed Hormuz tolls, prices rebound sharply.

Market Scenarios

Three paths forward — and what oil could cost

Analysts disagree sharply on trajectory, but the key variable is singular: when, and under what terms, does the Strait of Hormuz reopen? Three broad scenarios define the range of outcomes.

🕊 Bull scenario — Peace deal by June

A rapid ceasefire restores Hormuz flows before summer. Wood Mackenzie projects Brent eases to ~$80/barrel by year-end. Saudi Aramco warns it would still take months to normalize.

⚖ Base case — Prolonged stalemate

Negotiations drag through summer. IEA warns markets could enter a "red zone" by July as stocks deplete. Goldman Sachs forecasts Brent averaging $90 in Q4 2026.

🔥 Bear scenario — Hormuz stays shut

If Hormuz remains closed through year-end, Wood Mackenzie warns prices could approach $200/barrel. Citi projects $150 if flows remain disrupted through end of June.

Saudi Aramco CEO Amin Nasser delivered perhaps the starkest warning of all: even if Hormuz opens today, it will still take months for the market to rebalance — and if the opening is delayed further, normalization stretches into 2027. The oil market, in other words, cannot be switched back on like a light.

Investment Implications

The companies navigating this storm — and their stocks

Oil price crises do not affect all energy companies equally. Integrated supermajors with global production portfolios respond differently than pure-play upstream producers or oilfield service companies. Here is how key players across the sector are positioned.

The clear winners: Integrated supermajors

Strong beneficiary

As oil prices surge, Exxon's upstream operations generate dramatically higher profits, while its refining and chemical divisions provide cash flow resilience. The company's diversified Guyana and Permian production sits outside the Hormuz chokepoint, insulating it from supply disruptions. Wall Street maintains a strong buy consensus.

YTD performance+40% est.

Strong beneficiary

Chevron offers higher dividend yield than Exxon (4.5%), combined with meaningful Guyana exposure through the Hess acquisition. Its stock hasn't risen quite as much as crude prices — typically a sign that the full upside is not yet priced in. A prolonged war could send it substantially higher.

Dividend yield4.5%

Occidental Petroleum

High leverage play

Pure-play upstream producers like Occidental offer higher leverage to crude prices — they rise faster when oil surges. However, the same sensitivity cuts both ways: Oxy led S&P 500 premarket declines the day Trump predicted a swift peace deal. High risk, high reward.

Oil price sensitivityVery high

Structural beneficiaries: Oilfield services

SLB (Schlumberger)

Long-term beneficiary

The war is accelerating a structural rethink of global energy infrastructure, according to SLB CEO Olivier Le Peuch. Countries are now investing heavily in non-Hormuz supply routes and alternative production capacity — all of which require the services SLB provides. This is a multi-year tailwind.

ThesisInfrastructure cycle

Baker Hughes

Long-term beneficiary

Baker Hughes CEO Lorenzo Simonelli stated plainly that the war "is going to drive fundamental structural change across the energy landscape." Higher capex cycles globally, accelerated LNG buildout, and energy diversification spending all benefit BKR's service portfolio over the coming years.

ThesisCapex acceleration

The companies caught in the crossfire

NYSE: BP / LON: SHEL

Mixed exposure

European majors benefit from higher crude prices but face greater exposure to Middle Eastern refining and logistics infrastructure. Disruptions to Gulf-loaded tanker routes hit their supply chains harder than their U.S. counterparts. Higher prices help their upstream; the blocked trade routes hurt their integrated operations.

Key riskGulf logistics exposure

Saudi Aramco

Complex position

Aramco sits in a paradox: it has 2–2.5 million barrels/day of spare capacity that it cannot fully deploy because those barrels also need to exit via Hormuz. Drone strikes have reduced its Ras Tanura refinery capacity, and the East-West pipeline has seen throughput cut by ~700,000 bpd. High prices, constrained volumes.

Spare capacity issueHormuz bottleneck

"Crude is structurally bid in 2026. The combination of Iran-US tensions, Strait of Hormuz disruption, and a Fed worried about oil-driven inflation keeps crude in a higher range than fundamentals alone would justify."

Broader Impact

Beyond the price per barrel — the ripple effects

The effects of the Hormuz disruption extend well beyond crude oil. Natural gas prices in Europe and Asia have surged far more dramatically than in the United States — European gas is up more than 60% from pre-war levels — as LNG shipments routed through the Gulf face severe disruption. Diesel, jet fuel, petrochemical feedstocks, and fertilizers are all feeling the squeeze.

Chevron CEO Mike Wirth went as far as warning that fuel shortages are becoming a growing concern in certain regions of the world — not merely a question of price, but availability. The IEA noted that easily accessible buffers of refined products are being depleted rapidly, particularly naphtha, LPG, and jet fuel.

Collateral damage — beyond crude oil

European natural gas prices+63% since war began

Asian LNG spot prices+54% since war began

Diesel futures (Mar 2, peak)+20% single day

U.S. natural gas+7% (relatively insulated)

Jet fuel / naphtha / LPGRapidly depleting buffers

Market normalization timeline (if blocked past mid-June)Into 2027 — Aramco CEO

Developing nations in Asia and Africa are absorbing the worst of it, according to IEA Director Fatih Birol. Unlike wealthier countries that can draw down strategic reserves or absorb price spikes through subsidies, emerging economies face a raw inflation shock that feeds directly into food and transport costs.

Editorial View

The investor's dilemma: opportunity or overpriced risk?

For investors, the Iran war has created what looks, on the surface, like a clear trade: buy energy stocks while oil is elevated. But the reality is more nuanced. The energy sector had already gained roughly 20% year-to-date before the first missile was fired — tight fundamentals, underinvestment in upstream capacity, and a hawkish Fed worried about oil-driven inflation were already doing the heavy lifting. The war accelerated a move, not invented one from nothing.

The asymmetry of risks is critical. A deal that reopens Hormuz by June could send Brent back to $80, erasing significant gains in energy stocks virtually overnight — as Oxy's premarket plunge the day Trump predicted a swift end to the war illustrated vividly. Conversely, a prolonged blockade into Q3 or Q4 could see prices breach $150, with structurally lasting effects on global energy investment patterns.

The cleanest expression of the bullish view remains integrated supermajors — ExxonMobil and Chevron — whose diversified operations benefit from higher prices without being wholly dependent on Hormuz flows. For investors with a longer time horizon, oilfield services companies like SLB and Baker Hughes offer a more durable thesis: regardless of how this specific conflict resolves, it has permanently accelerated the structural investment cycle in energy infrastructure. That cycle does not end with a ceasefire.
