How the Strait of Hormuz, a narrow stretch of water where ships transport $1.2 billion worth of oil every day, is at the heart of spiraling tensions with Iran
Recent tensions between Iran and the West have been taking place near the Strait of Hormuz. Two oil tankers have been attacked, and Tehran has shot down a US drone, as well as seizing and harassing several British oil tankers. The narrow strait is the most important chokepoint for the world’s oil supply. Some 21 million barrels – or $1.197 billion worth of oil – pass through the strait every day. Iranian President Hassan Rouhani has repeatedly threatened to close the strait amid ongoing tensions, which would disrupt global oil supply and send prices shooting up.

Tensions between the West and Iran have bubbled to a historic height this summer, with both sides seeming to goad each other into war and Tehran appearing to isolate itself from the West. A series of maritime scuffles have taken place in the past two months alone:June 13: Two oil tankers, belonging to Norway and Japan, traveling in the Gulf of Oman are attacked. The US accuses Iran of being involved. Iran denies this. June 20: Iran shoots down a US drone flying near the same area. July 10: The UK government accuses Iran’s Revolutionary Guard corps of trying – unsuccessfully – to seize a British tanker in the Persian Gulf. July 18: Iran’s paramilitary Revolutionary Guard says it seized a “foreign vessel” in waters south of Iran earlier that week. Images of the seized ship appeared to be the MT Riah, a UAE-based ship that went missing around the same time. July 18: President Donald Trump says a US warship – USS Boxer – shot down an Iranian drone that came too close to it. Iran denies it. July 19: Iran seizes two British tanker ships sailing in international waters near Iran. One, the Mesdar, is released shortly after, but the other, the Stena Impero, remains in Iranian custody. What all these incidents have in common is their proximity to the Strait of Hormuz, the narrow body of water linking the Persian Gulf to the Gulf of Oman, which feeds into Arabian Sea and the rest of the world.Foto: Iran’s IRIB news agency showed wreckage of what it says is from the US drone that the Revolutionary Guard shot down on June 20.sourceIRIB News via Twitter Why is the Strait of Hormuz important? Though the strait is tiny – at its narrowest point it is just 33 km (21 miles) across – it’s a geopolitically and financially crucial chokepoint. It’s the world’s busiest shipping lane, chiefly because there are limited alternatives to bypass the strait. Most of the oil that passes through the strait come from Saudi Arabia, the US Energy Information Administration (EIA) reported. Some 21 million barrels of crude and refined oil pass through the strait every day, the EIA said, citing 2018 statistics. That’s about one-third of the world’s sea-traded oil, or $1.17 billion worth of oil a day, at current oil prices.Foto: Map showing marine traffic in the Strait of Hormuz on July 5, 2019.sourceMarineTraffic.com How important is the strait to the US? Shortly after the drone attack, President Donald Trump questioned the US’ presence in the region, and called on China, Japan, and other countries to protect their own ships passing through the Strait of Hormuz. Trump noted that much of China and Japan’s oil flow through the strait, and added: “So why are we protecting the shipping lanes for other countries (many years) for zero compensation.” “We don’t even need to be there in that the US has just become (by far) the largest producer of Energy anywhere in the world!” the president tweeted. While a large proportion – 76% – of oil flowing through the chokepoint does end up in Asian countries, the US still imports more than 30 million barrels of oil a month from countries in the Middle East, Business Insider’s Alex Lockie reported, citing the EIA. That’s about $1.7 billion worth of oil, and 10% of the US’s total oil imports per month.Foto: Oil tankers pass through the Strait of Hormuz on December 21, 2018.sourceHamad I Mohammed/Reuters How do US-Iran tensions affect it? Ongoing tensions between Iran and the West could result in Tehran shutting down international oil shipments in the strait, as President Hassan Rouhani threatened in late June. “We have always guaranteed the security of this strait,” Rouhani said, according to Deutsche Welle. “Do not play with the lion’s tail; you will regret it forever.” Iran has threatened to close down the strait multiple times in the past, as Business Insider’s Christopher Woody noted last year. If it were to follow through on its threats, it would likely cause huge disruption to the global oil trade. As the strait is so narrow, any sort of interference in tanker traffic could decrease the world’s oil supply, and send prices shooting up. Global oil prices have proven vulnerable to tensions between Iran and the West before. After the Trump administration said in April that it would stop providing sanctions waivers to countries who purchase Iranian oil, prices rose to their highest level since November, Axios said.Foto: A composite image of Iranian President Hassan Rouhani and US President Donald Trump.sourceSergei Chirikov/Pool via REUTERS; GOL/Capital Pictures/MediaPunch/AP And because the US would be affected by global oil prices, regardless of the origin of the oil, Washington would still have an interest in protecting the Strait of Hormuz. Kenneth Vincent, an economist at the Department of Energy, told a 2017 conference, cited by The Atlantic: “The origin of whatever molecules are consumed in the United States does not matter.” “What matters is that if there’s a shooting war somewhere in the Middle East, those molecules will cost more and that will harm the American economy,” he said. The US has recently been trying to get allies’ support to help it step up surveillance of shipping lanes on the strait to stop Iran from attacking commercial vessels, Reuters reported, citing unnamed sources familiar with the matter. But the allies have been reluctant to commit new weaponry or forces to the region, an unnamed senior Pentagon official told the news agency.Foto: An oil tanker on fire in the Gulf of Oman on June 13, 2019.

Iran is more likely to disrupt traffic in the Strait of Hormuz than to engage in an all-out conventional war with the US, which is much stronger militarily. But doing so comes with high costs to Iran. To close down the entire strait, Iran would have to place at least 1,000 mines with submarines and surface craft along the chokepoint, security researcher Caitlin Talmadge posited in a 2009 MIT study. Such an effort could take weeks, the study added. Disrupting oil traffic on the strait would also result in oil importers around the world looking beyond the Middle East for their sources, and further reduce reliance on the region. Iran’s oil industry is already suffering after the US imposed sanctions designed to stop countries from importing Iranian oil earlier this year. As Michael Knights, a Middle East expert at the Washington Institute think tank, told The Atlantic in May: “They’d be cutting their own throat if they close the strait.”The post How the Strait of Hormuz, a narrow stretch of water where ships transport $1.2 billion worth of oil every day, is at the heart of spiraling tensions with Iran appeared first on Business Insider Nederland.
