"If they (the West) impose sanctions on Iran's oil exports, then even one drop of oil cannot flow from the Strait of Hormuz," said Iran’s Vice President Mohammad Reza Rahimi to the Iranian news agency IRNA, as cited by Reuters.
According to the US Department of Energy, the Strait of Hormuz is “the world’s most important oil chokepoint”. On average, at least 13-15 oil supertankers cross the strait every day, carrying almost 33 percent of the world’s global seaborne oil supply from numerous Middle Eastern economies including Saudi Arabia, Iraq, Kuwait, Qatar and Iran.
Iranian officials have threatened to shut down the oil traffic through the strait in the past, though the comments made by the Vice-President have been the strongest thus far.
Last week, Iran’s navy started a 10-day exercise east of the passage, involving the use of submarines, ground-to-sea missile systems and torpedoes. The US Navy also conduct regular patrols of the waterways in order to prevent any sudden disruptions to the oil traffic.
As such, most analysts believe that Iran were unlikely to carry out its threat.
“To me, if Iran did that it would be a suicidal act by the regime. Even its friends would be its enemies,” said Phil Flynn, an analyst at PFG Best Research in Chicago, to the National Post.
The US State Department also said that it saw “an element of bluster” in Iran’s threat, dismissing the threat as a mere distraction.
According to Carl Larry, the president of Oil Outlooks in New York, the US would almost certainly intervene if a blockade does happen.
"First, the US will probably not allow Iran to close the Strait. That's a major economic thoroughfare and not just for oil. You shut that Strait and we are talking a major hit on many Middle East economies," said Larry.
