So the important thing to remember is the sheer quantity of oil that needs to be moved and where it needs to be moved to. The Strait of Hormuz in 2024 had 20 million barrels of oil passing through it daily. That’s 840,000,000 gallons or 3,160,000 cubic meters, or ~1300 Olympic swimming pools each day that need to be moved. It also mostly is going to end up getting moved across oceans to be delivered to the people who need it

Moving that much liquid by means other than boats is very difficult. Building pipelines that can move that much liquid is difficult and prone to problems. Especially considering the very harsh climate surrounding the area and even if you do have a pipeline it’s likely still going to end up in a ship because it has to cross an ocean anyway. Moving it by truck is almost logistically impossible, and trains have more problems than pipelines

In order to have the ships big enough to move that liquid you need ports that are deep enough AND already have the infrastructure to handle ships of that size, of which all are already in the Strait. It also made sense because a lot of oil producing countries were in this area so having lots of ships in the area built efficiency

So a whole bunch of confounding factors led to the Strait being the optimal place to move a lot of oil by ship (which the oil needed to go into anyway), however a natural choke point makes this a strategic position for countries in the area. Oil ships are slow, easy targets, and most countries could pretty cheaply take them out. Which adds to the tension in the region

This Wendover Productions video does a good job explaining why so much oil had to go through the Strait
