The standoff over Hormuz is edging toward a diplomatic track even as the shooting conflicts around it keep widening. A US official says Russia has accepted a proposal for trilateral talks with Ukraine, Washington has agreed to a technical-level meeting with Moscow and Kyiv, and the Kremlin floats Abu Dhabi as a venue. Trump's release of US citizen Stephen Hubbard from Russian custody and Iran's own signaling, with President Pezeshkian saying Tehran has no intention of starting a war and Foreign Minister Araghchi leaving the door open to diplomacy "if sincere," reinforce the sense that off-ramps are being tested on multiple fronts at once.

But the hard edges haven't softened. Iran's Revolutionary Guard says it will unveil a new weapon it calls the "Father of All Bombs," while a separate report says Trump has ordered plans drawn up to strike Iranian energy infrastructure with the US Mother of All Bombs if combat resumes. In Saudi Arabia, the Houthi conflict is escalating rather than cooling, with strikes claimed against Aramco's Dhahran headquarters and Yanbu, flight suspensions at Riyadh's King Khalid airport, and the Houthis themselves declaring talks with Riyadh dead and preparing for "all-round escalation." Aramco says Yanbu and Shaybah took no damage, and Kuwait's oil chief says Gulf crude supply remains ample with fuels, not crude, the real bottleneck, a distinction that's kept Brent and WTI from reacting as violently as the headlines might suggest. The Treasury's fresh Iran sanctions and authorization to offload cargo from some blocked vessels add to the sense of a slow unwind alongside the standoff.

Equities are looking past most of it. Super Micro Computer is up 9.5% on its preliminary sales guidance beat, and the broader risk-on tilt has lifted names like Datadog (+7.8%), Paramount Skydance (+7.9%), Strategy (+8.5%) and Charles River Laboratories (+8.1%). On the other side, AT&T is down 6.1% despite raising 2026 guidance, Chipotle is off 5.0%, DexCom down 5.5%, and FMC the worst performer at -6.5%. Natural gas is down 4.8%, a reminder that even with Hormuz unresolved, the energy complex isn't pricing a worst-case scenario, at least not yet.
