Washington announced an unprecedented economic pressure campaign against Tehran, pairing a naval blockade with sweeping financial penalties. United States Treasury Secretary Scott Bessent described upcoming measures as the toughest sanctions in history, targeting smuggling networks, exchange houses, and front companies to isolate the Iranian regime. President Donald Trump warned that any foreign institutions providing a lifeline to Iran would face severe economic consequences. In response to these announcements, international benchmark Brent crude climbed past ninety dollars a barrel, reaching a three week high amid growing supply disruption concerns. Administration officials argued that maximizing economic pressure will ultimately reduce the need for renewed military operations. Meanwhile, China, which purchases over eighty percent of Iranian seaborne oil exports, faced direct calls from Washington to support regional stability. Iranian Foreign Minister Abbas Araqchi strongly condemned the initiative as economic terrorism, while parliamentary leaders maintained that regional shipping routes will stay closed indefinitely now.
