The Strait of Hormuz: Where Oil Prices Are Made by Geography, Not Supply

What Is the Strait of Hormuz?

The Strait of Hormuz is a narrow maritime chokepoint connecting the Persian Gulf to the Gulf of Oman and onward to the Indian Ocean.

• Width: ~21 nautical miles at its narrowest

• Shipping lanes: ~2 miles wide in each direction

• Borders: Iran (north) and Oman/UAE (south)

There is no alternative sea route for Gulf oil to reach global markets.

Why It Matters for Oil (and LNG)

1. It’s the World’s Most Critical Energy Chokepoint

Roughly:

• ~20% of global oil consumption

• ~25–30% of seaborne crude trade

• ~20% of global LNG flows

pass through Hormuz every single day.

That includes exports from:

• Saudi Arabia

• Iraq

• Kuwait

• UAE

• Qatar (world’s largest LNG exporter)

➡️ No Hormuz = no Gulf exports at scale.

2. It’s Not Just About Closure — It’s About Risk

Markets often misunderstand Hormuz risk as binary: open or closed.
In reality, partial disruption is enough to move prices.

Even without closure:

• Tankers reroute closer to Oman

• Insurance premiums spike

• Freight rates jump

• Loading schedules slip

• Refiners delay or reshuffle runs

➡️ Execution friction, not blockage, is the real threat.

3. Iran Doesn’t Need to “Close” It to Control It

Iran exerts influence via:

• Naval presence and exercises

• GPS jamming and drone activity

• Harassment or seizure of vessels

• Legal and regulatory pressure on shipping

This creates persistent uncertainty, which:

• Raises war-risk premiums

• Alters chartering behavior

• Tightens tanker availability

➡️ Control comes from unpredictability, not force.

4. Alternatives Exist — But They’re Inadequate

Some Gulf producers have pipelines to bypass Hormuz:

• Saudi East-West pipeline (to Red Sea)

• UAE pipeline to Fujairah

But combined, they can only reroute a fraction of Gulf exports.

➡️ Hormuz remains structurally unavoidable.

What the Market Often Misses

Prices don’t move when Hormuz is “threatened.”
They move when shipowners change behavior.

Early warning signals include:

• Greek or Asian shipping advisories

• Sudden jumps in VLCC/Aframax war-risk premiums

• Reduced vessel willingness to load Gulf cargoes

• Freight dislocations before crude prices react

➡️ Freight moves first. Oil follows.

Why Hormuz Matters More in 2026+

The world is more exposed than before because:

• OPEC spare capacity is thinner

• LNG trade is less flexible than crude

• Energy supply chains are longer and more financialized

• Insurance, compliance, and sanctions amplify disruptions

Hormuz risk today is systemic, not regional.

Strategic Implications

For Traders

• Watch freight and insurance, not just Brent

• Position around execution risk, not supply loss

For Refiners

• Build crude slate optionality

• Avoid over-concentration in Gulf-dependent grades

For Investors

• Hormuz is a volatility engine

• Risk is underpriced until it’s suddenly not

Bottom Line

The Strait of Hormuz isn’t important because oil flows through it.
It’s important because oil cannot avoid it.
