Dow Jones drops 415 points as Iran conflict drives oil to $90
The Dow Jones Industrial Average fell 415 points on Tuesday after Iran seized a commercial tanker and Brent crude jumped above $90 a barrel.
All 30 Dow components closed lower, led by Boeing which dropped 3.8 percent and American Express which fell 2.9 percent, according to market data.
Investors sold airline, transport and consumer stocks as oil prices surged the most in a single session since March 2022, analysts said.
The sell-off began overnight after Iran’s Revolutionary Guards boarded the MSC Aries in the Strait of Hormuz and directed it toward Iranian waters, the U.S. Navy said.
The Portuguese flagged container ship, leased by MSC from Gortal Shipping, carried 25 crew including 17 Indians, the company confirmed.
Tehran state media said the vessel “violated maritime laws” but gave no specifics.
“Rising geopolitical risk in the Strait of Hormuz threatens the global oil supply,” RBC Capital analyst Helima Croft wrote in a client note.
The waterway handles about 20 percent of daily seaborne oil, the U.S. Energy Information Administration estimates.
Brent crude, the international benchmark, jumped $3.78 to $90.22, while U.S. West Texas Intermediate rose $3.56 to $85.89, exchange data showed.
The S&P 500 energy sector gained 1.1 percent, the only green patch in the broad index which fell 1.2 percent.
Background
Iran has threatened reprisals since Israel killed 7 Revolutionary Guards, including two generals, in an April 1 air strike on Tehran’s consulate in Damascus, Syria’s capital.
Western officials have warned for weeks that Iran could target Israeli or Western shipping in the Gulf, mirroring seizures in 2019 and 2020.
What’s Next
U.S. Secretary of State Antony Blinken is due in Brussels on Wednesday for NATO talks on protecting commercial vessels, according to the State Department schedule.
Analysts said energy traders will watch Israeli cabinet meetings and any U.S. naval movements for clues on possible retaliation.
