THE STRAIT OF HORMUZ AND THE FUTURE OF GLOBAL ENERGY: WHAT HAPPENS IF THIS ARTERY IS SEVERED?

📌 OPENING – THE WORLD'S MOST DANGEROUS 33 KILOMETERS

The Strait of Hormuz is only 33 kilometers wide at its narrowest point. Through this sliver of water passes 20% of global oil consumption and 25% of liquefied natural gas (LNG) .

Every day, approximately 17 million barrels of crude oil sail through this channel — past Iranian shore batteries, past American warships, past the constant threat of closure.

If Iran closes it — even partially, even temporarily, even just credibly threatens to close it — the global economy does not "slow down." It collapses.

This is not hyperbole. This is simple mathematics. Oil is the lifeblood of modern civilization. Every factory, every farm, every hospital, every home, every vehicle — everything that moves and everything that stays still — depends on energy.

A 20% sudden supply cut to the global oil market cannot be replaced. Not by Saudi Arabia. Not by the UAE. Not by the US Strategic Petroleum Reserve. The world does not have that much spare capacity.

For three years, Iran has held this sword over the global economy. It has not used it — not fully. Iran has threatened, but it has not followed through. Why? Because closing the strait would also hurt Iran. Because the US Fifth Fleet would try to reopen it by force. Because even China and Russia, Iran's allies, would not support a full blockade.

But what if the calculus changes?

What if Iran's nuclear facilities are struck by Israel? What if the US is seen as too weak to respond? What if Iran is desperate enough to risk everything?

These are not academic questions. They are the questions that keep energy ministers awake at night.

This is the ninth article in Cakranegara News' 20-part series on the Middle East crisis. We have already examined permanent crisis scenarios (Article 1), Palestine as a global symbol (Article 2), the triple economic triggers (Article 3), the new global bloc against the West (Article 4), the 10-year map reshaping (Article 5), the peace vs. war crossroads (Article 6), Palestine as a global issue (Article 7), and the Beit Shemesh explosion (Article 8). Now, in Article 9, we examine the single most dangerous chokepoint on earth: the Strait of Hormuz.

We will answer: What would happen if it were blocked? How long could the world survive? And what can Indonesia — and NTB — do to prepare?

📜 CHAPTER 1 – WHY HORMUZ IS UNIQUE

There are other chokepoints in global energy trade. The Strait of Malacca, the Suez Canal, the Bab el-Mandeb, the Turkish Straits. Each is important. But none is as critical as Hormuz.

Chokepoint Daily Oil Flow Alternative Route? Vulnerability

Strait of Hormuz 17 million barrels NO (Saudi/Iraqi pipelines have limited capacity) EXTREME

Strait of Malacca 16 million barrels YES (Lombok Strait, Sunda Strait, but longer) MODERATE

Suez Canal / SUMED Pipeline 5 million barrels YES (around Cape of Good Hope, +15 days) MODERATE

Bab el-Mandeb 4 million barrels YES (around Cape of Good Hope, +15 days) MODERATE

Turkish Straits 3 million barrels NO (only alternative is land pipelines through Russia) SIGNIFICANT

Hormuz is unique for three reasons:

Reason Explanation

Volume 17 million barrels per day — more than any other chokepoint on earth. No other single point controls this much energy flow.

No alternatives Other routes have bypasses. They are longer and costlier, but they exist. For Hormuz, there is no bypass. The Saudi and Iraqi pipelines that could theoretically replace Hormuz have insufficient capacity.

Iranian control Iran sits on one side of the strait. It has threatened to close it repeatedly for decades. It has the military capability to do so — not permanently, but long enough to cause catastrophic economic damage.

"The Strait of Hormuz is the jugular vein of the global economy. Cut it, and the world bleeds out in weeks." — Former US Energy Secretary

🔥 CHAPTER 2 – THE CLOSURE SCENARIO: BY THE NUMBERS

What actually happens if Iran closes the Strait of Hormuz? Let us walk through the nightmare scenario, day by day, week by week.

Phase One: The Announcement (Day 1)

Event Oil Price Global Consequence

Iran announces "temporary military exercise" blocking the strait $120/barrel (from baseline $85) Stock markets fall 10% globally

Insurers immediately raise war risk premiums for tankers $130/barrel Some shippers refuse to transit

US Fifth Fleet goes on high alert — Risk of US-Iran conflict spikes

Phase Two: The Panic (Days 2-7)

Event Oil Price Global Consequence

Saudi Arabia offers to replace lost volume — but cannot (limited spare capacity) $150/barrel Supply chain chaos begins

China and India plead with Iran to reopen $160/barrel Diplomatic crisis between Iran and its allies

US considers military action to reopen the strait $170/barrel Global markets brace for war

Phase Three: The Crunch (Weeks 2-4)

Event Oil Price Global Consequence

Strategic Petroleum Reserves (SPR) in US, China, Japan, India, Europe are released $175/barrel (temporary relief) Reserves are finite; world watches the countdown

Some tankers risk the passage under US naval escort $180/barrel Partial supplies resume, but insurance costs are astronomical

Alternative routes (Cape of Good Hope) add 15 days and 30% cost $190/barrel Not enough volume to replace Hormuz

Phase Four: The Collapse (Months 2-3)

Event Oil Price Global Consequence

Strategic reserves are depleted $220/barrel Governments consider rationing

Rationing begins in some countries $250/barrel Gasoline lines, food price spikes

Global recession deepens into depression $300/barrel (spot prices) Developing countries face hunger

The math: The world has approximately 60-90 days of oil supply in strategic reserves. After that, rationing begins. After that, the global economy grinds to a halt.

"Iran does not need to fire a single missile. It just needs to close a 33-kilometer stretch of water for two months. The West will beg for negotiations." — Iranian military commander (paraphrased)

🧠 CHAPTER 3 – HOW LIKELY IS A CLOSURE?

Iran has threatened to close Hormuz many times — usually in response to US sanctions or military threats. It has never actually done so. Why?

Reason Explanation

Self-damage Iran's own oil exports (now ~1.5 million barrels per day) also flow through Hormuz. Closing the strait would hurt Iran as much as it hurts the West.

US retaliation The US Fifth Fleet is based in Bahrain, just across the strait. It would attempt to reopen the strait by force, risking a direct US-Iran war.

Global backlash Even China and Russia, Iran's allies, would not support a full blockade. They need oil too.

But what has changed in 2026?

New Factor Impact on Iran's Calculus

Israel-Hezbollah war Iran is already involved indirectly in the conflict. Escalation is easier when you are already at war.

US distraction The US is focused on the Eastern European crisis and domestic politics. It is perceived as weak and distracted.

Russia's support Russia has provided Iran with advanced electronic jamming technology and anti-ship missiles, increasing Iran's confidence.

Desperation If Iran's nuclear facilities are struck by Israel, all bets are off. A desperate Iran might close the strait out of revenge or as a last resort.

The probability assessment:

Scenario Probability

Full Hormuz closure 15-20%

Credible threat causing price spike without full closure 60-70%

No significant disruption 15-25%

"The probability of a full Hormuz closure is low. But the probability of acredible threat that spikes oil prices to $150-200/barrel is much higher. And that is enough to cause a global recession."

🌏 CHAPTER 4 – WHY THIS MATTERS FOR INDONESIA & NTB

Indonesia is a net oil importer. Every barrel that passes through Hormuz — or fails to pass — affects the price Indonesia pays for fuel.

Impact on Indonesia Mechanism Severity

Fuel subsidy explodes Oil at $150/barrel = subsidy > Rp 800 trillion (from current ~Rp 400 trillion) 🔥 CATASTROPHIC

Fertilizer prices spike Natural gas prices are linked to oil; farmers cannot afford urea 🔥 HIGH

Food prices spiral Transportation costs for imported wheat, rice, soybeans skyrocket 🔥 HIGH

Rupiah collapses Capital flees emerging markets; dollar scarcity; central bank reserves drain 🔥 HIGH

Investment stops Global uncertainty freezes foreign direct investment ⚠️ MODERATE

For NTB families: The difference between a contained crisis and a full blockade is the difference between paying Rp 10,000/liter for fuel and paying Rp 25,000/liter. Between buying fish and not being able to afford rice. Between sending children to school and pulling them out because of rising costs.

What Indonesia should do NOW:

Action Why Feasibility

Build strategic oil reserves Not just talk — actually buy and store oil for emergencies. Indonesia's current reserves are minimal. MODERATE (costly but possible)

Diversify energy sources Solar, geothermal, wind, nuclear — reduce dependence on imported fossil fuels. LONG-TERM (but must start now)

Strengthen food security Increase local rice, corn, and soybean production. Do not rely on global markets that will fail in a crisis. HIGH (political will required)

Prepare for rationing Contingency plans for fuel rationing if worst-case happens. Know which sectors get priority. LOW-COST (planning only)

"Indonesia cannot prevent a Hormuz blockade. But Indonesia canprepare. Not with panic. With planning."

🔮 CONCLUSION – PREPARE FOR THE WORST, HOPE FOR THE BEST

The Strait of Hormuz is not going away. Iran is not going away. The risk of a closure — even temporary, even just a credible threat — is real and growing.

The world has been lucky for decades. Iran has threatened, but never followed through. That luck may not hold forever.

Indonesia is not a superpower. It cannot force Iran to keep the strait open. It cannot replace the oil that would be lost. But Indonesia can prepare — not with panic, but with planning. Not with fear, but with foresight.

For the readers of Cakranegara News, the lesson is to understand that global energy security is more fragile than most people realize. And that fragility can reach your fuel tank in Cakranegara within weeks of a crisis.

The question is not whether the Strait of Hormuz is dangerous. It is. The question is: Are we prepared for what happens when that danger becomes reality?
