Strait of Hormuz traffic returns to normal by end of June?

Platform comparison

Market context

The Strait of Hormuz remains effectively closed to commercial shipping, with traffic at a near-standstill for weeks amid the ongoing Iran war, driving up oil prices and disrupting global goods flows[3][5]. This chokepoint, critical for global energy markets, has seen commercial vessels suspended after a brief reopening, leaving the strait in a state of closure[4]. The current crowd-implied probability of 0% for a return to normal by end of June reflects this stark reality, as no credible data suggests a rapid recovery is imminent.

Historically, similar geopolitical disruptions in the region, such as the 2019 tanker attacks, caused temporary drops in traffic but saw swift rebounds once diplomatic agreements were reached[9]. However, the current situation differs significantly due to the scale of the US-Iran conflict and the explicit naval blockade of Iranian ports, which is only set to be lifted by July 19[2]. In the past, traffic surged to its highest level in two months following a deal to halt the war, but this recent surge was followed by a sharp drop amid regional escalation, indicating fragile stability[7][9].

Traders should monitor the US-Iran agreement finalized on June 17, which guarantees immediate commencement of commercial navigation, and the scheduled lifting of the naval blockade by July 19[2]. Recent news from CNN notes that 25 commercial vessels traversed the strait on Thursday, marking the highest volume since April, yet this volume remains far below the 60-ship threshold required for the market to resolve to "Yes"[2]. The divergence between platforms like Polymarket (decimal odds, lower fees, minimal KYC) and Kalshi (implied probability, higher fees, strict KYC) on this market highlights how fee structures and regulatory reach can influence liquidity and pricing for such high-risk, geopolitically sensitive events.
