Escalating regional tensions involving Iran, the United States, and Israel have sustained trader focus on potential full airspace closures, with recent partial reopenings of eastern routes and limited airport operations offset by ongoing military alerts and new transit rules in the Strait of Hormuz. Developments such as selective vessel restrictions and Iranian accusations tied to civilian incidents have reinforced perceptions of heightened alert levels, while historical precedents of short-term shutdowns for drills or security reasons provide context for the current pricing. Scheduled diplomatic channels and any reported military movements through late May remain key variables that could shift the implied probabilities reflected in the market.
