The United States has reimposed Iran oil sanctions, citing recent attacks on commercial vessels in the Strait of Hormuz, a move that has pushed global crude oil prices up by more than 5%.
The renewed sanctions follow the U.S. Department of the Treasury’s allegation that Iran sought to target commercial vessels sailing through the waterway. If Iran threatened to disrupt international shipping and maritime security, it would face the consequences, a U.S. official said.
Earlier this year, a U.S.-Iran deal allowed Tehran to export oil until August 21. Washington has since tweaked the arrangement, however, and has extended the sales period until July 17, before the sanctions come into full effect.
The news had immediate consequences on the energy sector, as BRENT crude and global oil prices climbed by more than 5% due to the intensified tensions in the Middle East.
In the meantime, the U.S. announced that it has conducted airstrikes against specific targets in Iran. The military operation was initiated in response to Iran’s alleged attack on three commercial vessels in the Strait of Hormuz, U.S. Central Command (CENTCOM) said.
The CENTCOM said that a military response is continuing to stop more attacks and to protect the international shipping lanes. The command said Iran “took a dangerous step without provocation and a threat to world maritime security.
The latest developments have raised concerns about regional stability, global energy supply and the future of international shipping via the Strait of Hormuz one of the world’s most significant oil transport arteries.
