Ongoing US-Iran tensions since February 2026 continue to suppress commercial traffic through the Strait of Hormuz, the key conduit for roughly one-fifth of global oil and LNG flows. IMF PortWatch data show daily transits averaging in the low teens to low 20s in mid-to-late August 2026, versus pre-conflict baselines near 130 vessels, amid IRGC controls, elevated war-risk insurance premiums (around 40 times normal), and selective blockades. Recent August 22–24 figures of 4–16 transits underscore persistent deterrence, with oil shipments occurring via limited or dark-tankers routes but at sharply reduced volumes supporting Brent prices near $92 per barrel. Trader consensus on Polymarket thresholds (e.g., 30+ ships on any day by August 31) prices in low odds of near-term normalization given the short window to resolution and absence of verified de-escalation. Any IMF PortWatch release in coming days or diplomatic signals could shift implied probabilities before month-end settlement.

Transit calls include container, dry bulk, roll-on/roll-off, general cargo, and tanker ships. Ships not reported by IMF Portwatch will not be considered.
Data for a specific date must be finalized before it is considered for this market (namely, once the next date's data point is available, the previous one is finalized).
This market will resolve as soon as a qualifying figure has been finalized or once all relevant data has been finalized. If the data for the final date of the specified timeframe has not been finalized by the end of the third calendar day (ET) after the day on which such data is first released, this market will resolve based on data published up to that point. Additionally, if not all relevant data has been released and finalized within 14 calendar days of the end of the specified period, this market will resolve based on data published up to that point.
In case of obvious data integrity issues (i.e., erroneous data), the market may remain open until the end of the third calendar day (ET) after the date on which such data is first released to allow for corrections. Data integrity issues refer only to clerical or other similar errors in the underlying data, and do not include cases where IMF Portwatch differs from alternative sources.
Only revisions to previously published data points made before the applicable resolution time will be considered.
The resolution source for this market will be IMF Portwatch, specifically the transit calls data published for the Strait of Hormuz at https://portwatch.imf.org/pages/cb5856222a5b4105adc6ee7e880a1730, both in the chart and through downloadable files.
