President Trump's US naval blockade of the Strait of Hormuz, imposed April 12, 2026, after US-Iran peace talks collapsed over nuclear issues, persists into its third week with no lifting announcement, anchoring trader consensus on extended timelines. Recent statements from Trump indicate preparations for prolonged enforcement despite surging oil prices—now averaging $4.35/gallon regular—and global economic pressure, while Iran offers to reopen the strait only if the US ends the blockade and hostilities. US Central Command reports effective halts on Iranian port traffic, but international allies resist joining. Key upcoming: May 1 congressional deadline for Trump to justify extension or wind down, potentially tipping diplomatic negotiations or escalation signals.
