Markets lean NO at 58%, but a 42% YES tail reflects active conflict spillover risk that keeps closure plausible through June.
Iran's airspace remained partially operational as of May 23, 2026, with national carriers Mahan Air and Iran Air resuming routes to Beijing, Shanghai, Guangzhou, Bangkok, Moscow and Islamabad following a ceasefire pause in active hostilities. The reopening followed a brief closure during the most intense phase of strikes, when Saudi Arabia shut Prince Sultan Air Base and its own airspace for 36 hours on May 5, disrupting kinetic options Washington had staged through the kingdom. The question of whether Iran closes its airspace again by June 30 now hinges on a fragile diplomatic track, with Tehran confirming on May 18 that it had responded to a new US proposal it described as "excessive" while continuing back-channel exchanges.

Hawks in Washington argue the open-skies window is the regime's primary economic lifeline and should be shut immediately. The National Security Council convened on May 19 with the Chairman of the Joint Chiefs and Secretary of Defense present, signaling that kinetic options remain executable rather than theoretical, with most credible plans routing through Saudi airspace or a B-2 sortie from Diego Garcia. Analysts at The Atlantic caution that Iran retains a structural advantage in destabilization scenarios, while Gulf neighbors including the UAE face acute economic exposure if regional aviation corridors collapse again. Tehran separately announced on May 18 the formation of a new body to manage the Strait of Hormuz, warning Gulf states against cooperating with Israel. [Times of Israel, May 18]
Whether Iran closes its airspace before June 30 will be determined by three converging variables: the outcome of US-Iran proposal exchanges, the readiness posture of Israeli and US strike packages, and Saudi willingness to reopen Prince Sultan Air Base for a second window. Forbes reported on May 21 that Middle East tourism patterns have already shifted measurably, with carriers rerouting around the region and safety perceptions damaged for the medium term. A renewed Israeli or US strike package would almost certainly force Tehran to close civilian corridors defensively, while a negotiated freeze would keep current limited operations intact. The structural determinant remains the May–June diplomatic clock that President Trump described as "ticking." [Forbes, May 21]
