Gate Of Tears Could Soon Be Iran War's Next Stranglehold

An oil tanker leaving Saudi Arabia for the Netherlands, for example, only has to travel 12,000 kilometers if it goes via the Red Sea, compared with more than 20,000 kilometers if it goes south around Africa.

As you'd expect, that's much faster too. According to the US Energy Information Administration (EIA), a trip between the Arabian Sea and the Netherlands that takes 34 days the long way around is shortened to just 19 days.

In normal times, as much as 14% of global maritime trade goes through the Bab el-Mandeb Strait. Detailed data on what passes through the Bab el-Mandeb Strait is somewhat limited. But fossil fuels are a major component.

The International Energy Agency (IEA) estimates that in 2025 about 4.2 million barrels of crude oil and petroleum liquids crossed the Bab al-Mandeb Strait per day. That's about 5% of global production.

Given most ships use the Suez Canal as well, official data from the Suez Canal Authority allow us to paint a detailed picture of Red Sea shipping.

In the final quarter of 2025, about 40% of the 3,426 ships passing through the Suez Canal transported fossil fuels: (1,330 oil tankers, 88 liquefied natural gas (LNG) ships).

Bulk and general cargo made up another 40% (1,339 ships), typically transporting agricultural commodities such as corn, wheat and soybeans, and also coal and iron ore. Container ships made about 13% of the traffic (459 ships).

Notably, total traffic through the Red Sea has declined considerably since Houthi attacks on shipping in late 2023 and 2024, even though these attacks have largely stopped.

The Bab el-Mandeb Strait can't be“closed” entirely. Its narrowest point is still a considerably wide waterway.

And unlike the Strait of Hormuz, the Bab el-Mandeb Strait is not a“cul-de-sac”, where the passage is closed at one end with only one way out. Ships can still exit to the Mediterranean via the Suez Canal.

That's little comfort for those bound for Asia, which would then have to round Africa to do so, adding weeks to the journey.

Notably, Saudi Arabia had already built a“Plan B” to avoid the Strait of Hormuz, called the East-West pipeline. This pipeline connects Abqaiq in the north with Yanbu on the Red Sea, and had already begun pumping oil at almost full capacity in response to the conflict.

But oil bound for Asia from this new exit point still has to pass through Bab el-Mandeb to avoid the long way around, meaning it could be disrupted.

To get a sense of how the Houthis could disrupt shipping again, we can look to the most recent Red Sea crisis.
