Strait of Hormuz traffic returns to normal by September 30?

Platform comparison

Market context

Polymarket prices this contract at **24% Yes**, so the crowd is still leaning to a delayed normalisation rather than a full return to a 7-day average of 60 ships or more before 30 September. On Polymarket, the position is held in **USDC** on **Polygon**, with the event resolved through the platform’s **conditional token** structure once IMF Portwatch publishes the relevant moving average.

The recent history explains why that price is still well below even-money. The Strait of Hormuz has spent much of 2026 far below pre-war flow, with Reuters saying traffic was at less than 10% of typical volumes in April and other reporting describing only a handful of vessels moving at points in the spring.[5][9][12] Even after June de-escalation talk, the route has remained volatile: the New York Times reported traffic was still significantly below pre-war levels despite a preliminary U.S.–Iran arrangement, while ABC said fresh attacks exposed how fragile the ceasefire-linked reopening remained.[8][11] That backdrop matters because the market does not need the strait to be “open” in a general sense; it needs IMF Portwatch’s 7-day average to clear 60, which implies a sustained and broad return across tankers, bulk, container, ro-ro and general cargo traffic.

For traders, the main catalysts are any enforcement or security announcements around the U.S.–Iran understanding, shipping advisories, and whether carriers restore regular schedules rather than only sending occasional transits. Reuters has already shown how quickly the market can move from near-standstill to partial recovery, but the evidence so far suggests the final stretch depends on whether insurance, naval risk and route confidence improve enough for volume to stay elevated rather than spike briefly.[5][8][11] Because settlement is tied to IMF Portwatch’s published 7-day average, the practical watchlist is the tracker itself: a few busy days are not enough if the rolling figure does not hold above 60.
