The Strait of Hormuz: the throat of the planet
There’s a point on the map that, if closed, would bring the global economy to its knees: the Strait of Hormuz . This narrow channel, barely 33 kilometers wide, carries 20% of the world’s daily oil and liquefied natural gas . When Iran threatens to block it, markets are on edge, and analysts begin to paint scenarios that just a few months ago seemed like science fiction.
In March 2026, that scenario became urgently real. Military tensions between Iran , the United States , and Israel escalated to the point where spokespeople for the Iranian Revolutionary Guard Corps publicly warned that if hostilities persisted, the price of oil could reach $200 a barrel , a level never before seen in history.
The mechanism of chaos: why a lockdown triggers prices
To understand the magnitude of the problem, one must consider supply and demand under extreme pressure. The closure of the Strait of Hormuz would generate a supply deficit of approximately 20 million barrels per day .

The market has to absorb the rest. And since energy demand is extremely inelastic in the short term (economists estimate an elasticity of -0.1 ), the adjustment occurs almost exclusively through price.
During the most tense sessions of the crisis, Brent crude from the North Sea reached $101.59 per barrel , rising by as much as 9% in a single day . US WTI crude approached $96 . This occurred before a complete shutdown; it was simply the geopolitical risk premium.
Iran, Saudi Arabia and the strategic chessboard
Iran ‘s most powerful leverage point is the Strait of Hormuz. According to international news agencies, it has already deployed mines and ships in the area, and at least three commercial vessels have been hit by projectiles in the strait. The United States ‘ military response included the destruction of 16 Iranian minelayers , but this did not de-escalate the situation.
On the other side of the board, Saudi Arabia has its own card to play: the pipeline that connects its oil fields directly to the Red Sea , bypassing the Strait of Hormuz. Faced with the crisis, the kingdom increased the flow through this route. However, experts warn that this alternative is insufficient if the pipeline is attacked or if the Yemeni Houthis , allies of Iran, resume their operations in the Red Sea, a scenario we already experienced between 2023 and 2024.
Interdependence is at the heart of the problem: the Gulf countries need to export, the world needs to import, but the most efficient route passes through an area of active conflict.
Faced with soaring prices, the International Energy Agency (IEA) took the most drastic decision in its history: to release 400 million barrels of strategic reserves from its member countries. To put that figure into perspective, the release agreed upon after Russia’s invasion of Ukraine in 2022 was less than half that amount.
This measure allows for the temporary injection of an additional 3 to 4 million barrels per day into the market, buying time for diplomacy to take effect. By regulation, IEA member countries must maintain reserves equivalent to 90 days of imports , which provides some leeway but does not eliminate the structural pressure.
The result was mixed: prices briefly eased, but nervousness quickly returned. As economist Olivier Blanchard —former chief economist of the IMF —explained, the price of oil could stabilize permanently between $150 and $200 per barrel if the geopolitical situation is not resolved in the short term. Not as a speculative peak, but as a new equilibrium.

Impact on the world economy: from the gas station to the recession
A barrel of oil holding steady at $200 isn’t just a problem for drivers or airlines. It’s an inflation multiplier that permeates every sector of the economy. The most conservative models project:
- Domestic and industrial energy: increases exceeding 12%.
- Natural gas: increases of around 2% additional due to the substitution effect.
- Transportation and logistics: increased costs that are passed on to all physical goods.
The aggregate result would be double-digit inflation in energy-importing economies, forcing central banks to raise interest rates in an already fragile environment. The risk of a synchronized global recession would cease to be a tail scenario and become the base-case scenario.
For emerging markets in Latin America , the impact would be asymmetric: net oil-exporting countries like Colombia, Venezuela, or Brazil would receive an extraordinary flow of income, while importing economies like Chile, Uruguay, or much of Central America would suffer a balance of payments shock that would be difficult to mitigate.
Alternative routes: Is there a way out?
Beyond the strategic reserves, there are alternative routes to the Strait of Hormuz, although all have significant limitations:
- Petroline pipeline (Saudi Arabia): capacity of up to 5 million barrels per day to the Red Sea. Currently operational, but vulnerable.
- IPSA pipeline (Abu Dhabi): capacity of 1.5 million barrels per day to the Arabian Sea. In operation.
Taken together, these alternatives could cover a fraction of the deficit, but the gap between available supply and actual demand would remain enormous as long as the strait remains blocked or at risk of being blocked.
What this means for founders and tech companies in LATAM
This crisis may seem like a problem for oil tankers and energy ministries. But founders building startups in Latin America can’t ignore its operational and strategic implications.
- AWS, GCP, and Azure costs: The data centers of major cloud providers are energy-intensive. A sustained energy shock will eventually translate into higher energy bills.
- Logistics and hardware: any startup that handles physical inventory, IoT devices, or hardware will see its supply chain become more expensive.
- End-user purchasing power: In markets where disposable income is already tight, double-digit inflation shrinks the consumer market for mid-to-high-ticket digital products.
- Opportunities in energy efficiency and ClimateTech: crises accelerate transitions. The scenario of oil at $200 is the largest implicit subsidy renewable energy has ever received.
Conclusion
The scenario of $200 per barrel is not alarmist fantasy: it is the logical projection of a global energy system that depends on a single geographical bottleneck controlled by an actor with incentives to use it as leverage. The IEA can release reserves, Saudi Arabia can redirect flows, and governments can enact contingency plans, but until the conflict surrounding the Strait of Hormuz is resolved, structural uncertainty will continue to define the market price.
For founders and teams building in this environment, the key isn’t predicting the exact price of a barrel of oil, but designing businesses resilient enough to operate under different macroeconomic scenarios. Volatility, in this case, isn’t a bug in the system: it’s the new normal.
