Red Sea crisis highlights ‘clear and present danger’ of wider war involving Iran

Futures saw further losses in early trade Wednesday.

Market participants appear to have widely subscribed to the notion that the Israel-Hamas war will remain confined largely to Gaza and don’t present a threat to shipments of Middle East crude supplies, said Helima Croft, head of global commodity strategy at RBC Capital Markets, in a Tuesday note.

“However, we still see a clear and present danger that this will become a wider regional conflict, with three flashpoints posing particular contagion concerns,” she wrote.

“Iran is at the center of all three threat vectors and the question of whether the Gaza conflict will metastasize is likely to hinge on whether Tehran maintains any appreciable degree of distance from its proxies or becomes a main character, either through its own direct actions or because it is targeted for retaliation for its extensive armed network,” she said.

Here are the three potential flashpoints that bear watching, according to Croft:

Houthi attacks on shipping

The map below points to major incidents around the Red Sea in recent weeks:

News outlets citing Iran’s semi-official Tasnim news agency on Monday reported that an Iranian warship, Alborz, had entered the Red Sea, albeit without providing details of the ship’s mission.

That came after the U.S. military said Sunday that its forces opened fire on Iran-backed, Yemen-based Houthi rebels after they attacked a Maersk-operated

cargo ship in the Red Sea, killing several rebels and destroying three boats in an escalation of the maritime conflict linked to the war in Gaza. Maersk on Tuesday said it would pause all transit through the Red Sea and the Gulf of Aden until further notice.

Meanwhile, there are indications that the U.S. and U.K. are preparing a larger military operation against the Houthis in Yemen, Croft noted. If so, a key question is whether Iran will remain a bystander.

Croft said it was also noteworthy that Saudi Arabia has reportedly been urging restraint in response to rising Red Sea unrest. Houthi attacks on Saudi targets have abated since a cooling of Saudi-Iran tensions last March. A more serious U.S./Houthi/Iran confrontation could imperil Saudi Arabia’s newfound security gains, she said.

Lebanon and Hezbollah

Senior Biden administration officials have made frequent trips to Beirut recently, in an effort to avert the opening of a second warfront on Israel’s northern border pitting the nation’s armed forced against the militant Hezbollah movement.

Israel and Hezbollah have traded fire since the Oct. 7 start of the Israel-Hamas war but actions have remained relatively contained. Tensions and fighting have increased in recent weeks, however.

An expansion of the conflict into Lebanon would present a “clear pathway” to a wider regional war given Iran’s extremely close operational relationship with Hezbollah, Croft said, noting that Tehran’s ties with the group are much stronger than its alliance with the Houthis.

A more-direct Iranian role in the war would sharply increase the threat to regional energy supplies, Croft added — not only because of Iran’s energy assets, but also due to its ability to curtail traffic through the Strait of Hormuz (see map below).

The strait is a narrow waterway that links the Persian Gulf with the Gulf of Oman and the Arabian Sea. At its narrowest point, the passage is only 21 miles wide, while the width of the shipping lane in either direction is just two miles and separated by a two-mile buffer zone. It’s the world’s most sensitive oil-transportation choke point.

“While much of the current market focus is on the Red Sea and the Bab el-Mandeb choke point, the Strait of Hormuz is far more consequential for global energy supplies, with an average of 15 million barrels a day of OPEC+ crude traveling through the waterway in 2023,” Croft said.

Iraq firefights

Iran-backed militias have fired hundreds of rockets at bases housing U.S. troops and areas near U.S. personnel in Iraq and Syria, prompting a series of escalating retaliatory strikes by the U.S. military, Croft noted.

“While the militia attacks have injured multiple U.S. soldiers, to date no U.S. servicemen have been killed,” she said. “We do not know whether President Biden shares his predecessor’s kinetic redline over the loss of American life. However, we believe that if continuing assaults by Iran-backed forces lead to significant American casualties, Washington could find itself drawn back into another round of active fighting in Iraq.”

Croft said the potential for election-year personnel changes in the Biden administration were also worth watching.

“Given the relatively small number of officials that are crafting the response to the war, any departure from this team could have implications for key aspects of the White House engagement,” she said.
