What’s Happening

The prospect of an **iran full airspace closure by december 31** remains a live geopolitical risk, driven by a conflict that has already forced repeated, costly shutdowns across the region. Iraq has kept its airspace closed since **February 28**, with the government extending the suspension by **72 hours** as US and Israeli strikes on Iran continue and Tehran responds across the Middle East. That closure alone has cost an estimated **$43 million**, according to Shafaq News, underscoring the severe economic toll of a prolonged no-fly zone over a key transit corridor. The Iraqi decision mirrors a broader pattern of precautionary shutdowns that have rippled through the region since the escalation began. [Shafaq News, Mar 31]

European regulators have institutionalized the threat, with the **European Union Aviation Safety Agency (EASA)** issuing a formal advisory on **July 8** telling airlines to avoid Iranian and Iraqi airspace until **August 31**. The agency acted after recent US attacks and remarks by President **Donald Trump** raised concerns over renewed military escalation, revising its conflict zone advisories in coordination with the European Commission. This followed an earlier Reuters report from **February 12** in which a safety body urged EU airlines to avoid Iran airspace until **March 31**, a deadline that has since been extended multiple times. While some carriers like **SWISS** have begun a phased return to northeastern Iranian airspace as of **August 27**, they continue to avoid the rest of Iran, Iraq, and Israel, reflecting a cautious, data-driven approach to a volatile threat environment.

The structural factor that will determine whether an **iran full airspace closure by december 31** materializes is the trajectory of US-Iran military exchanges, which have already triggered partial and full shutdowns. Iran has partially reopened its airspace, allowing transit through eastern routes, while Iraq and Israel have reopened theirs but remain subject to short-term closures, according to a **January 24** report from Cntravellerme. US embassies in the region have issued alerts warning citizens of possible airspace closures and flight cancellations, urging “heightened vigilance.” The key variable is whether Washington and Tehran can sustain a de-escalation or whether renewed strikes force a comprehensive, indefinite closure before year-end. As of now, the market assigns a **28% probability** to a full closure by **December 31**, with the **72% NO** outcome reflecting the partial reopenings and phased returns seen in recent weeks.
