Trump Issues Military Ultimatum to Iran Amid Shadow Banking Sanctions and Resumed Talks

The U.S.-Iran conflict entered a dual-track escalation on Saturday, July 11, as President Donald Trump formally declared the mid-June ceasefire void while simultaneously allowing technical nuclear talks to resume in Oman. The U.S. has issued a public ultimatum demanding Iran guarantee free passage through the Strait of Hormuz. This follows a period of intense military activity, with the U.S. hitting 170 targets earlier this week. In a major strategic shift, the Trump administration also expanded economic pressure by sanctioning a 'shadow banking' network, including Dubai-based assets linked directly to Supreme Leader Mojtaba Khamenei. Despite the heightened military posture—including President Trump’s confirmation that 1,000 missiles are locked on Iranian targets—backchannel diplomacy continues via mediators. U.S. officials, including Secretary of State Marco Rubio and special envoy Jared Kushner, are operating through Omani intermediaries. Iranian officials have privately characterized recent maritime attacks as 'errant' mistakes by domestic hardliners seeking to derail the talks. However, Tehran publicly maintains its right to control the Strait of Hormuz, calling U.S. demands for free passage a requirement for 'surrender.' On the economic front, the new sanctions target eight individuals and six entities accused of facilitating IRGC financial operations. Concurrently, the U.S. is reportedly finalizing an investment deal with Iraq intended to curb Iranian influence in Baghdad. While limited fire was exchanged in the Strait of Hormuz over the last 24 hours, no new large-scale attacks were reported as of Saturday morning, though the U.S. maintains that all previous memorandums of understanding are now void.
