Iran’s parliament has voted to close the Strait of Hormuz, a vital oil route carrying 20 of global crude. Though the final decision awaits the Supreme National Security Council, the move is seen as retaliation to U.S.-Israel attacks on Iranian nuclear sites. A closure would rattle global oil markets, spike prices, and disrupt trade—particularly hitting import-dependent countries like India. Iran seeks leverage over the West and a show of regional strength, but risks military backlash and damage to its own economy.
