1. The Persian Gulf Once Again Tightens the Global Energy Market

The escalation of conflict in the Persian Gulf and the growing tensions along energy export routes are reopening a debate that once seemed dormant: who can realistically replace Middle Eastern oil if a major disruption occurs?

The Strait of Hormuz—through which nearly one third of the world’s seaborne oil trade passes—has once again become the critical chokepoint of the global energy system.

Every time this strategic corridor is threatened, the market is reminded of an uncomfortable reality: global energy security depends on very few geographic points.

In this context, some analysts are beginning to ask whether Latin America could play a more significant role as an alternative energy supplier, particularly to Europe and Asia.

2. Iraq and the Risk of a Massive Supply Loss

One of the most concerning developments is the situation in Iraq, one of the world’s largest exporters of heavy crude oil.

According to various market reports:

• Iraq may have already shut down approximately 1.5 million barrels per day of production.

• If disruptions in the Strait of Hormuz continue, losses could approach 3 million barrels per day.

To put this into perspective:

• Total Iraqi production: 4.0 – 4.3 million bpd

• Typical exports: 3.2 – 3.4 million bpd

A disruption of 3 million barrels per day would represent one of the largest sudden supply losses in the modern oil market, outside of open wars or international sanctions.

---

3. The Oil Heartland of Southern Iraq

Most Iraqi oil production comes from the giant oil fields in the south of the country, which supply the Basrah export terminals where most of the crude is shipped abroad.

Among the most important fields are:

Oil Field	Approximate Production
Rumaila	1.3 – 1.5 million bpd
West Qurna 1	~600,000 bpd
West Qurna 2	~460,000 bpd
Zubair	Up to 700,000 bpd capacity
Maysan	300,000 – 350,000 bpd

Together, these fields form the backbone of Iraq’s export engine.

A disruption approaching 3 million barrels per day would effectively paralyze a large portion of the southern oil system, removing from the market large volumes of medium and heavy sour crude.

---

4. Can OPEC Compensate for the Loss?

This leads to the key question troubling the market:

Does OPEC have enough spare capacity to replace Iraqi oil?

The answer depends on how that capacity is defined.

The U.S. Energy Information Administration (EIA) distinguishes between two key concepts:

• Maximum sustainable capacity: what a producer could reach within roughly one year.

• Effective spare capacity: what can be added to the market within 90 days without damaging fields or infrastructure.

For practical purposes, markets focus on the second definition.

Under that criterion, OPEC’s real spare capacity is estimated at:

3 to 4 million barrels per day

But there is a critical detail.

Almost all of that capacity is concentrated in just two countries:

Country	Estimated Spare Capacity
Saudi Arabia	~2 million bpd
United Arab Emirates	0.8 – 1 million bpd

The rest of the members contribute only marginal volumes.

---

5. The Logistical Problem Few Mention

Even if Saudi Arabia and the UAE quickly increased production, a structural problem would remain:

That oil must also pass through the Strait of Hormuz.

Therefore, the limitation would not only be production, but also:

• maritime congestion

• higher insurance costs for tankers

• shipping delays

• possible reluctance by shipping companies to operate in the region

In other words:

Capacity in the oil fields does not necessarily mean barrels on ships.

---

6. The Factor That Further Complicates the Market: Crude Quality

Not all barrels are the same.

Iraqi crude is mostly medium and heavy sour crude, the type of oil for which many Asian refineries are specifically configured.

Iraq’s main buyers are:

• China

• India

Together they absorb roughly two-thirds of Iraqi exports.

Replacing that oil with lighter crude changes:

• refining yields

• diesel production

• refinery margins

For this reason, even if alternative barrels existed, not all of them would be equivalent for the global refining system.

---

7. Latin America Returns to the Global Energy Radar

Amid this structural fragility in the oil market, some analysts are once again turning their attention to Latin America.

The region holds some of the largest hydrocarbon reserves on the planet, particularly concentrated in:

• Venezuela

• Brazil

• Guyana

• Mexico

In particular, Venezuela possesses the largest proven oil reserves in the world, much of it in heavy crude comparable to that of the Middle East.

If a prolonged disruption occurred in the Persian Gulf, Europe and Asia might be forced to further diversify their supply sources, potentially placing Latin America back at the center of the global energy map.

---

8. Implications for Markets and Investors

For financial markets, the lesson is clear.

The global oil system operates with much narrower safety margins than official figures suggest.

A disruption approaching 3 million barrels per day could:

• push oil prices higher

• widen heavy crude price differentials

• increase transportation costs

• raise volatility in energy markets

At the same time, it could accelerate investment in:

• energy infrastructure

• exploration in underdeveloped regions

• production in Latin America

---

Conclusion

The global oil market remains extremely sensitive to geopolitical shocks.

The situation in Iraq shows that OPEC’s so-called spare capacity may be closer to its real limit than many analysts believe.

If the global energy system wants to reduce its vulnerability to regional crises, geographic diversification of supply—including greater energy development in Latin America—will likely return to the center of the global agenda.

🌍 Can Latin America Help Stabilize the Global Energy Market?

Growing tensions in the Middle East—from the Persian Gulf to the Strait of Hormuz—once again remind the world of a reality it often forgets:

Global energy security depends on very few extremely sensitive geographic chokepoints.

Today more than 20% of the oil traded worldwide passes through the Strait of Hormuz.

Any disruption along that route—whether due to regional conflicts, infrastructure attacks, or maritime blockades—can generate immediate effects on oil prices, inflation, and global economic growth.

In that context, a strategic question emerges:

If part of Gulf production is interrupted… who can help balance the market?

One of the most interesting answers lies in Latin America.

The region holds massive reserves, many still underdeveloped, and several countries are already increasing production significantly:

• 🇧🇷 Brazil, with its giant offshore pre-salt development

• 🇬🇾 Guyana, one of the fastest-growing oil producers in the world

• 🇦🇷 Argentina, with the potential of Vaca Muerta

• 🇻🇪 Venezuela, with the largest proven reserves on the planet

• 🇨🇴 Colombia, with stable export-oriented production

Together, these countries could play an increasingly important role as alternative energy suppliers to Europe, Asia, and North America in a world where geopolitics once again dominates markets.

But the challenge is not only geological.

It also depends on:

• political stability

• legal certainty

• investment in infrastructure

• access to energy technology

• and a coherent regional strategy

In other words, Latin America has the opportunity—but not the guarantee—of becoming one of the major energy pillars of the 21st century.

For investors, analysts, and policymakers, this scenario raises key questions about:

In the new article on the Feliz y Saludable blog, I analyze how the crisis in the Persian Gulf could accelerate Latin America’s energy role in the global system.

The energy geopolitics of the 21st century may also be written from the South Atlantic.
