Iran Claims It Has Full Control Over The World’s Most Important Oil Chokepoint

As the first round of U.S. sanctions on Iran kicked in earlier this month and the second round of sanctions—including on Iranian oil exports—is set to snap back in early November, the Islamic Republic is stepping up rhetoric about controlling the most vital oil flow chokepoint in the world, the Strait of Hormuz.

On Monday, General Alireza Tangsiri, the head of the navy of Iran’s Revolutionary Guards, was quoted by Iranian media as saying that Iran had full control of the Persian Gulf and the Strait of Hormuz.

“There is no need for foreigners such as the United States and the countries whose home is not here,” Tangsiri was quoted as saying by Iran’s PressTV.

U.S. Secretary of State Mike Pompeo said later on Monday in a statement posted on Twitter: “The Islamic Republic of Iran does not control the Strait of Hormuz. The Strait is an international waterway. The United States will continue to work with our partners to ensure freedom of navigation and free flow of commerce in international waterways.”

The Strait of Hormuz is the world’s most important chokepoint, with an oil flow of 18.5 million bpd in 2016, the EIA estimates. The Strait of Hormuz connects the Persian Gulf with the Gulf of Oman and the Arabian Sea and is the key route through which Persian Gulf exporters—Saudi Arabia, Iran, Iraq, Kuwait, Qatar, the UAE, and Bahrain—ship their oil. Only Saudi Arabia and the UAE have pipelines that can ship crude oil outside of the Persian Gulf and have additional pipeline capacity to bypass the Strait of Hormuz, which is a route of more than 30 percent of daily global seaborne-traded crude oil and petroleum products and more than 30 percent of the liquefied natural gas (LNG) flows.

Some 80 percent of the crude oil shipped through the Strait of Hormuz goes to Asian markets, EIA has estimated using data from Lloyd’s List Intelligence tanker tracking service. China, Japan, India, South Korea, and Singapore are the largest destinations for oil moving through the Strait of Hormuz.

Before the previous Western sanctions were imposed earlier this decade, Iran also threatened to block the Strait of Hormuz, and although analysts think that it would struggle to do so due to the U.S. naval presence in the area, a further flare-up in the Tehran-U.S. relations could be a risk to the oil flows in this vital global chokepoint.

Earlier this month, the U.S. Central Command said that there was increased Iranian military activity in the Strait of Hormuz.

A few days earlier, U.S. Defense Secretary James N. Mattis told Pentagon reporters, commenting on Iran’s threats to close the Strait of Hormuz at the end of July:

“Clearly, this [closure] would be an attack on international shipping and could have an international response to reopen the shipping lanes … because the world’s economy depends on those energy supplies flowing out of there.”

According to the August 6 report ‘Iran’s Threats, the Strait of Hormuz, and Oil Markets: In Brief’ by the Congressional Research Service, “Threats of U.S. sanctions that could reduce Iran’s oil export earnings is a key impetus to Iran’s threats to close the Strait of Hormuz.”

However, due to its own dependence on trade via Hormuz, “Iran may be unlikely to attempt to close the waterway, but rather to shape the international debate on Iran policy,” Michael Ratner, Specialist in Energy Policy, writes in the report.

Referring to Iran’s options regarding the Strait of Hormuz, the report points out that an outright closure is a “low probability event” and even if Iran manages to pull it off, it is unlikely to be prolonged because it would trigger military response from the U.S. and other countries to keep freedom of navigation in the area. Harassment of tankers or infrastructure damage, if Iran were to use that, could send oil prices higher, but also “runs the risk of triggering a military response and alienating Iran’s remaining oil customers,” according to the report.


Iran, however, could continue to make threats about the Strait of Hormuz without taking action, and conduct naval exercises to stoke up tension.

“The statements and maneuvers could still raise energy market tensions and contribute to higher oil prices, though only to the degree that oil market participants take such threats seriously,” the report notes.

    Aren’t you glad we have “Oil Company Senators” like John Barrasso and Ted Cruse and the API that block any competition to their and our, oil addiction?

    These are American Senators and Organizations that are blocking year-round availability of E-15, blocking ethanol fuels helps to keep us on the hooked to the likes of Iran. Send our Sons and Daughters over there to die for the API and our Oil Addiction, and be glad you didn’t tell Iran to Kiss Off with High Octane American Ethanol. Ha, your kids are Dying for the API.

    If Iran means by the claim that it has full control geographically of the world’s most important oil chokepoint, namely the Strait of Hormuz, then this is not correct. Three countries have control of the Strait: Iran on the north coast and UAE and Oman on the south coast.

    If, however, it means that it controls the Strait militarily, this is also not correct since it is impossible for Iran to close the Strait completely. At its narrowest, the Strait has a width of 29 nautical miles (54 km).

    The Strait of Hormuz is the world’s most important chokepoint with an oil flow of 18.5 million barrels a day (mbd) or 20% of global oil and 30% of the world’s LNG (from Qatar) passing through the Strait daily.

    Oil exports from Iraq, Iran, Kuwait, Bahrain, Qatar, the UAE and Saudi Arabia must pass through the Strait. All of them with the exception of the UAE and Saudi Arabia will not be able to export any oil if the Strait of Hormuz is closed or mined.

    Iraq, OPEC’s second largest exporter of oil, is totally dependent on the Strait of Hormuz for its oil exports since the Iraqi-Turkish pipeline known as the ITP transporting Iraqi oil from Kirkuk to Ceyhan on the Turkish coast on the Mediterranean is currently out of action.

    Iran has threatened to close the Strait of Hormuz if it was prevented from exporting its crude oil as a result of US sanctions. Iran’s threat should be taken seriously.

    However, Iran is neither able to close the Strait completely nor does it need to do that to disrupt the flow of oil through the Strait. it could achieve its objectives by mining it stealthily with the expectation of a mine hitting an oil tanker and sinking it. Such an accident in itself would deter tankers from crossing the Strait thus causing a disruption in oil supplies until the mines are cleared.

    Alternatively, Iran could threaten sinking tankers crossing the Strait even if escorted by the US Fifth Navy in the Gulf. This threat might deter tanker owners around the world from sending their tankers across the Strait under pressure from global insurance companies until tension has subsided.

    A disruption of oil shipments through the Strait of Hormuz for a lengthy period could send oil prices far above $150 a barrel.

    If only there was an allie and trading partner on the same continent as the U.S.. you know, the great white North with enough oil to easily supply the us, instead of buying it from elsewhere.
