In the port of Muscat, the early morning hours are frequently quiet. With their decks piled high with pipes and antennas, tankers drift in the distance like dark silhouettes against the pale blue water, waiting for orders that might or might not come. The Strait of Hormuz appears almost tranquil from the shore. Just a stretch of water between desert and mountains.
However, a staggering portion of the world economy is transported through this tiny route, which is just wide enough for shipping lanes that wind between Omani cliffs and Iranian islands.

On most days, more than 150 vessels pass through the strait. Crude is transported from the Persian Gulf to Asia, Europe, and North America by oil tankers, which make up the majority of the traffic. This corridor transports about one-fifth of the world’s oil supply. This fact alone explains why energy traders keep an almost compulsive eye on the area.
However, the actual effects of closing the Strait are more nuanced than an increase in oil prices.
Due to the escalating conflict in the area, maritime traffic through the passage has drastically decreased in recent weeks. Daily transits are only a small portion of what they used to be, according to ship-tracking data. In certain instances, insurance companies have increased shipping costs by up to 300%, subtly deterring ships from coming into the region at all.
It becomes clear how brittle the system is when one is standing on a cargo pier in the Gulf. Large tankers, some of which are longer than three football fields, travel slowly through two nautical mile-wide lanes. One turn, one delay, one warning from a naval command center, and the entire chain of global trade begins to wobble.
Energy markets react quickly. Oil prices have already surged during the crisis, briefly climbing toward levels not seen since the shocks of the early 2020s. Traders are good at remembering the past.
The oil crises of the 1970s, triggered by Middle Eastern disruptions, reshaped global economies almost overnight. In American cities, gas lines were established. Europe saw a sharp increase in inflation. Governments scrambled to rethink energy security.
Watching the current tensions unfold, there’s a faint echo of that era. But oil is only part of the story.
A surprising share of the world’s fertilizer ingredients, including sulphur and ammonia, also travels through the Strait of Hormuz. Roughly one-third of global fertilizer trade depends on this route. If shipments stall for long enough, the consequences ripple far beyond energy markets. Food prices eventually follow.
Fertilizer imports from Gulf producers are vital to farmers in parts of Africa, Brazil, and India. Harvests become more costly when energy costs increase and fertilizer supplies become scarce. That change appears months later on grocery store shelves, disguised as slightly higher prices for bread, rice, or vegetables. The ripple’s distance from a small stretch of water thousands of kilometers away is difficult to ignore.
Shipping firms are well aware of this risk. Dispatchers now monitor every ship entering the area inside maritime control rooms, which are dimly lit areas with satellite charts and radar screens. Ships have already been rerouted by some companies around the southern tip of Africa, resulting in longer travel times and fuel expenses of millions of dollars.
Looking at that detour on a map makes it seem almost unreal. Instead of navigating the Gulf and the Suez Canal, a tanker sailing from Saudi Arabia to Europe abruptly takes the long arc around Cape Town. The entire geography of trade is altered by a single geopolitical chokepoint.
There’s another quiet complication. In order to send oil westward toward the Red Sea, a number of Gulf nations have constructed pipelines that avoid the strait. Theoretically, these paths lessen reliance on Hormuz. In reality, they are weak and constrained.
Attacks on pipeline infrastructure in the past have demonstrated how challenging it is to ensure safe energy flows in an area where naval mines, missiles, and drones are ongoing threats. Shipping lanes that encircle hostile coastlines are difficult for even strong navies to completely secure.
Military strategists are well aware of this. Protecting ships in the strait would require a steady convoy system, warships providing air defense, and constant surveillance against mines and small attack craft. It may be effective for a brief time. Maintaining it for several months is a completely different story.
In the meantime, nations distant from the Gulf experience the tension in more subdued ways. Fuel costs are hedged by airlines. Shipments are delayed by manufacturing companies. Emergency oil reserves are reviewed in secret by governments.
Despite decades of globalization, there is a perception that the global economy still depends on a small number of brittle arteries.
The fragility is evident when one observes the ships congregate outside the Gulf, awaiting safe passage. While their crews pace the decks and check news updates from far-off capitals, some ships remain at anchor for days.
The strait still appears serene from the shore. Blue water. waves that are slow. Tankers dotted the horizon. Beneath that exterior, however, is a complex reality. The Gulf is not affected when this small gateway slows down or stops. They cover the whole world in silence, ship by ship.
