The fear of an Iranian oil calamity in Hormuz is more than just a myth.

Fears of Middle East oil disruption after US strikes on Iran

Iran has attempted to blockade the Strait of Hormuz in the past.

US Navy is likely to respond quickly in the event of disruptions

LONDON, 22 June - The U.S. strikes against several Iranian nuclear sites are a significant escalation in the Middle East conflict. This could cause Tehran to disrupt essential exports of gas and oil from the region, causing a spike in energy prices. History tells us, however, that any disruption will likely be brief.

Since Israel launched surprise airstrikes on Iran on June 13 investors and energy markets were on high alert, fearing disruption of oil and natural gas flows from the Middle East. This was especially true for the Strait of Hormuz - a chokepoint that connects Iran with Oman, and through which 20% of global demand for oil and natural gas passes.

Since June 13, Brent crude oil prices have increased by over 10%, to more than $77 per barrel.

Although Israel and Iran have both targeted their respective energy infrastructures, there has not been a significant disruption of maritime activity in the area so far.

The decision of President Donald Trump to bomb three of Iran's nuclear sites early Sunday morning, along with Israel, could change Tehran's calculations. Iran has few options and could respond by attacking U.S. targets in the region or disrupting oil flow.

Although such a move is almost certain to lead to an abrupt spike in energy prices worldwide, the history of the market and its current dynamics suggests that any move will likely be less harmful than investors fear.

Can they do it?

First, we need to know if Iran has the capability of blocking or seriously disrupting the Strait of Hormuz.

Answer: Probably yes. Iran could try to place mines in the Strait which measures 34 km wide (21 miles at its narrowest). The Iranian army or paramilitary Islamic Revolutionary Guard Corps could also strike or seize ships in the Gulf. This is a tactic they have used in recent years.

Hormuz was never completely blocked but it has been interrupted several times.

During the Iran-Iraq War of the 1980s, both sides were involved in what was called the "Tanker Wars", which took place in the Gulf. Iraq attacked Iranian ships and Iran attacked commercial vessels, including Saudi, Kuwaiti, and U.S. Navy ships.

Ronald Reagan, the then-President of the United States, deployed his navy in 1987 and 1988 after Kuwait appealed to him. This was called Operation Earnest Will. The operation ended shortly after an American navy ship shot down Air Iran Flight 655 killing all 290 of its passengers.

At the end of 2007, tensions in the Strait erupted again in a series skirmishes involving the Iranian and U.S. Navy. One incident involved Iranian speedboats approaching U.S. battleships. No shots were fired. In the Gulf of Oman, Iranian troops captured the Advantage Sweet crude oil tanker chartered by Chevron in April 2023. The vessel was freed more than a full year later.

The U.S. Navy would respond to any Iranian attempt at disrupting maritime traffic in the Gulf with a swift, forceful response, thus limiting the possibility of a long-lasting supply shock.

HISTORY LESSON

History has shown that major disruptions in global oil supply have been short-lived.

Brent crude doubled to $40 per barrel in mid-October 1990 after Iraq invaded Kuwait. By January 1991, prices had returned to pre-invasion levels after a U.S. led coalition launched Operation Desert Storm. Kuwait was liberated the following month.

Even less impactful was the start of the second Gulf War between March and may 2003. The 46% rise in stock prices between November 2002 to March 2003, which was the period leading up to the war, was reversed quickly in the days before the U.S. led military campaign.

In February 2022, Russia invaded Ukraine, causing oil prices to spike to $130 per barrel. However, prices fell back to $95 in mid-August, their levels before the invasion.

The rapid rise in oil prices curbed the demand at the time, and this was a major factor for the relatively quick turnaround of the oil price spikes, according to Tamas Varga an analyst with oil brokerage PVM.

The global oil market was also shook by the Arab embargo of 1973 and the Iranian revolution of 1979, when attacks on oilfields in the country severely disrupted the production. These attacks did not include the blockade of Hormuz, and they were not met by a direct military response from the United States.

There is certainly spare capacity on the current global oil markets. OPEC+ is an alliance of oil producing nations that holds around 5.7 millions barrels of excess capacity per day. Saudi Arabia and United Arab Emirates have 4.2 million bpd.

Today, the Strait of Hormuz is the main route through which oil is transported from Saudi Arabia and UAE.

However, the two Gulf countries could bypass this strait via oil pipelines. Saudi Arabia is the top oil exporter in the world, with around 9 million barrels per day. It has a crude oil pipeline that runs between the Abqaiq Oilfield in the Gulf Coast in the east and the Red Sea port of Yanbu in west. The pipeline can handle 5 million barrels per day and has been temporarily expanded by 2 million barrels per day in 2019.

The UAE produced 3.3 millions bpd of oil in April. A 1.5 million bpd oil pipeline links its oilfields on the coast to the Fujairah terminal, east of the Strait of Hormuz.

This western route is also vulnerable to the attacks of the Houthis, who are backed by Iran and have disrupted the Suez Canal shipping in recent years. Iraq, Kuwait, and Qatar have no other alternative to the Suez Canal.

Iran may decide not to block the Strait, in part, because it would disrupt its oil exports. Tehran may also see any further escalation as futile in light of U.S. intervention and instead downplay the importance and return to nuclear negotiations.

Fearing a further escalation of the situation, the energy markets are likely to react to the U.S. strike with a dramatic increase in crude oil prices. Even in the worst-case scenario, where the Strait of Hormuz was blocked, historical evidence suggests that markets shouldn't expect a persistent supply shock.
