Iran and Oman have maintained long-standing diplomatic ties as littoral states sharing the Strait of Hormuz, with Muscat frequently serving as a mediator in regional disputes. However, the 2026 Iran-US conflict and associated Hormuz shipping crisis have produced direct Iranian drone and missile strikes on Omani ports such as Salalah and Duqm, which host facilities used by US forces, resulting in casualties and operational disruptions since March. Bilateral talks on temporary navigation corridors, mine clearance, and joint management frameworks advanced in mid-2026 but stalled in September amid Saudi objections and broader GCC concerns over fees, veto rights, and status quo changes. Recent high-level calls between Iranian and Omani leaders have reaffirmed commitments to stability, yet enforcement of blockades, attacks on shipping, and internal Iranian debates over leverage continue to shape escalation risks through the resolution window.
