Strait of Hormuz traffic returns to normal by December 31?

Platform comparison

Market context

Commercial shipping through the Strait of Hormuz is currently suspended, with no outbound vessels recorded over the past 72 hours, creating a severe bottleneck that threatens global energy flows. This acute closure starkly contrasts with the 89% crowd-implied probability that transit calls will return to a seven-day moving average of 60 or above by December 31, 2026. While sportsbook lines on similar geopolitical disruption contracts often lag behind prediction-market odds, the divergence here suggests analysts are betting on a rapid diplomatic thaw despite the immediate operational paralysis.

Historical precedents from the 1980s Tanker War and the 2019 oil tanker seizures show that Hormuz closures typically resolve within weeks, not months, once regional tensions de-escalate. The current probability of 89% aligns with this pattern, implying that the market views the June 2026 shutdown as a temporary tactical measure rather than a permanent strategic blockade. However, the absence of verified outbound movements over the last 72 hours, as noted by HormuzTracking, introduces a risk that the settlement threshold of 60 arrivals may not be met if the closure persists beyond the summer.

Traders must monitor the IMF PortWatch monthly traffic flow reports and any announcements from Iran regarding the reopening of the choke point, as these are the primary catalysts for resolving the market. Recent data from MarineTraffic indicates that nearly 20 vessels transited in a single 24-hour window during April, suggesting the strait retains capacity when open. The key dependency is whether the seven-day moving average of transit calls can reach 60 before the settlement window ends, a target that remains achievable only if the current suspension lifts within the next six months.
