Strait of Hormuz traffic returns to normal by July 15?

Platform comparison

Market context

Ships are currently trickling through the Strait of Hormuz after a brief reopening, with commercial navigation suspended again following Iran’s reversal of the waterway’s access. An agreement between the United States and Iran, finalized on 17 June, guarantees that commercial traffic will commence immediately, and the US must fully lift its naval blockade of Iranian ports by 19 July. Yet, despite this diplomatic progress, sporadic attacks on vessels and war-risk cover expiry have kept transits at a near-standstill for weeks, sending oil prices higher and disrupting global energy flows[2][3][6].

Historically, similar geopolitical standoffs in the region have seen transit volumes rebound only after concrete de-escalation measures, such as the 8 April 2026 ceasefire, which nonetheless failed to restore normal traffic levels[10]. The current 38% crowd-implied probability reflects skepticism that the 7-day moving average of arrivals will reach 60 before the 15 July settlement, especially given that 25 vessels crossed on 18 June—the highest since April—but remain below the threshold required for a “Yes” resolution[2][5]. Platforms diverge here: Polymarket users trade decimal odds (roughly 1.62) with low fees and no KYC, while Kalshi traders face implied probabilities, higher fees, and strict identity verification, affecting liquidity and risk exposure on this binary outcome.

Traders should monitor the US blockade lift deadline of 19 July, any new Iranian attack announcements, and weekly transit counts from AXSMarine or MarineTraffic. Recent reports note that carriers like Mediterranean Shipping Company have pushed sharp rate hikes amid war-risk fears, and some tanker owners continue transiting without AIS despite missile threats[1][2]. A sustained rise in daily arrivals above 60 would be the key catalyst, but current data suggests this remains unlikely before the settlement window closes.
