Oil at $109 and Strait of Hormuz Blocked: The World Faces Its Worst Energy Crisis in 50 Years

Category: Society | Date: March 18, 2026 | Read: 20 minutes | ⛽

On March 18, 2026, Brent crude oil surpassed $109 — a 6% jump in a single day — after naval analysts confirmed what the market feared: navigation through the Strait of Hormuz has become "virtually impossible." The strait, through which 20% of all oil consumed worldwide passes, is surrounded by Iranian naval mines, threatened by Revolutionary Guard anti-ship missiles, and patrolled by American warships. Commercial oil tankers, without insurance or escort, have simply stopped trying to cross.

The result? The worst energy crisis since the 1973 Arab oil embargo. And unlike 1973, this time the world is far more dependent, far more interconnected, and far more vulnerable.

The Strait of Hormuz: Why It Matters So Much #

Scary Numbers #

The Strait of Hormuz is a passage only 33 km wide at its narrowest point, connecting the Persian Gulf to the Gulf of Oman and, from there, to the Indian Ocean. Through this strip of water passes:

In summary: If Hormuz closes, 1/5 of all the world's oil simply disappears from the market overnight.

Who Depends on Hormuz #

The countries most affected by the blockade are those importing oil from the Gulf:

The Economic Impact: The Numbers Are Brutal #

Oil: The Price Spiral #

Oil has risen 51% in less than 7 weeks. For comparison: in 1973, the Arab embargo caused a 300% increase — but over 6 months.

Global Production Loss #

Global oil production dropped 8 million barrels per day in March:

• Iran: Exports zeroed (Kharg Island bombed)
• Kuwait: -1.5 million bpd (logistical disruption)
• Iraq: -1 million bpd (pipelines damaged)
• Saudi Arabia: -500,000 bpd (precaution)
• UAE: -500,000 bpd (QatarEnergy facilities hit)
• Others: -500,000 bpd (ships stranded, refineries without feedstock)

Gas Prices Worldwide #

Gas prices have already begun rising globally:

Forecast for Brazil: Analysts estimate gas could reach R$7.50 to R$9.00 per liter if the conflict lasts until April — an increase that would have devastating impact on freight costs and, consequently, food prices.

The Responses: What the World Is Doing #

1. IEA Releases 400 Million Barrels #

On March 11, the International Energy Agency (IEA) announced the largest coordinated release of strategic reserves in history:

• USA: 180 million barrels (from SPR — Strategic Petroleum Reserve)
• Japan: 75 million barrels
• South Korea: 30 million barrels
• Europe (total): 115 million barrels

The problem: 400 million barrels equals less than 50 days of supply lost from Hormuz closure (8 million bpd × 50 days = 400 million). It's a bandaid on a severed artery — buys time but doesn't solve the problem.

2. US Eases Venezuela Sanctions #

The US Treasury Department announced easing of sanctions on Venezuelan oil — a desperate maneuver to increase global supply. Venezuela has the world's largest proven oil reserves (303 billion barrels), but its industry has collapsed after decades of mismanagement and sanctions.

Venezuelan production:

• Theoretical capacity: 3 million bpd
• Current production: ~750,000 bpd
• Possible production with investment: 1.5 million bpd (in 12-18 months)
• The irony: The same Venezuela the US sanctioned is now seen as a lifeline

3. OPEC+ Increases Production (Insufficient) #

OPEC+ agreed to add 206,000 barrels/day starting in April — a drop in the ocean compared to the 8 million bpd lost. Saudi Arabia has spare capacity of ~2 million bpd but hesitates to use it all for strategic reasons.

4. Alternative Routes #

Gulf producers are exploring routes that bypass Hormuz:

• East-West Pipeline (Saudi Arabia): From Persian Gulf to Red Sea — 5 million bpd capacity
• IPSA Pipeline (Iraq-Turkey): 1.6 million bpd capacity, but vulnerable to sabotage
• ADCOP (UAE): Pipeline carrying oil from Abu Dhabi to Fujairah port, outside Hormuz — 1.5 million bpd

Historical Comparison: The 5 Largest Oil Crises #

The current crisis is already the 5th largest in oil history — and it's still just beginning.

The Impact on Your Wallet: What's Getting More Expensive #

Oil doesn't just affect gasoline. It's in everything:

Global Inflation: The Domino Effect #

How Expensive Oil Causes Inflation in Everything #

Oil isn't just fuel — it's the base for 6,000+ derived products. When the barrel rises 50%, the cascade effect hits the entire economy:

Chain 1: Transportation → Food

• Diesel rises → Road freight rises → Carriers pass on costs → Supermarkets pass to consumers → Rice, beans, meat get more expensive
• In Brazil, 65% of food is transported by road. Every 1% diesel increase = ~0.3% food increase within 60 days

Chain 2: Petrochemicals → Everything

• Naphtha (petroleum derivative) is raw material for: plastics, packaging, paints, resins, fertilizers, synthetic fabrics, medications
• Every product containing plastic (i.e., almost all of them) becomes more expensive

Chain 3: Energy → Industry

• Natural gas (which follows oil prices) powers thermal plants
• In drought-season Brazil, thermal plants are activated to compensate for hydroelectric — electricity bills rise
• Energy-intensive industries (aluminum, steel, cement) pass on costs

Impact on the 85 Most Vulnerable Countries #

The UN has already reported that 85 countries registered fuel price increases since the conflict began. The most affected:

Energy Transition: Accelerated by the Crisis? #

The Paradox of Expensive Oil #

Paradoxically, the Hormuz crisis may accelerate the transition to renewable energy:

Arguments in favor:

• Governments and consumers have urgent incentive to reduce oil dependence
• Electric vehicle sales should rise 30% in 2026 (BloombergNEF forecast)
• Solar and wind investments should increase 20% as a response to energy insecurity
• Sodium-ion batteries (CATL) offer a cheaper, lithium-free alternative

Arguments against:

• The transition takes decades, not months — the world needs oil NOW
• Critical minerals (lithium, cobalt, rare earths) also have supply bottlenecks
• Charging infrastructure is still insufficient in most countries
• Renewables depend on fossil backup (thermal plants) during periods without sun/wind

The verdict: The 2026 crisis will be remembered as the tipping point that finally convinced governments that dependence on Gulf oil is an existential risk. But the effective transition will take 20-30 years.

Frequently Asked Questions (FAQ) #

Can the Strait of Hormuz stay closed for months? #

It's possible but unlikely. The global economic pressure is so intense that both the US and Iran have incentives to reopen the strait. The question is: at what political cost?

Can Brazil run out of oil? #

Not in the short term. Brazil produces ~3.4 million bpd and exports more than it imports in crude. But since Petrobras practices international price parity, prices rise in Brazil even when there's no physical shortage.

Do electric cars get cheaper during the crisis? #

In theory, yes — the crisis increases the incentive to abandon fossil fuels. In practice, batteries depend on minerals (lithium, cobalt) that also have elevated prices. But EV sales should increase 30% in 2026.

How long do strategic reserves last? #

The 400 million barrels released by the IEA last about 50 days at the current rate of loss. After that, without peace or alternative routes, there will be a real supply crisis.

Does Russia benefit from the crisis? #

Enormously. Russia exports ~7 million bpd and, with oil at $109, earns ~$280 billion more per year. It's no coincidence that Moscow hasn't pushed for a cease-fire.

Conclusion: Oil Is Still the World's Blood #

The March 2026 crisis proves, painfully, what experts have warned for decades: the world is still dramatically dependent on oil, and most of that oil passes through a 33-km geographic bottleneck.

While warships patrol Hormuz and missiles cross the Gulf skies, every gas station in Brazil, every market in Japan, every airport in Europe feels the direct impact. Globalization is a double-edged sword: it connects everything, but when something breaks at the weakest link, the entire world bleeds.

For the average Brazilian, the crisis materializes in concrete ways: the already expensive liter of gasoline becomes prohibitive, grocery shopping weighs heavier on the wallet, Uber and freight costs skyrocket. Imported inflation through oil respects no borders and hits hardest those least able to absorb the increase.

The barrel at $109 is just the beginning if peace doesn't come soon. And the lesson is clear: as long as the world doesn't diversify its energy sources in a real and urgent way, we'll always be hostages to 33 kilometers of water at the exit of the Persian Gulf.
