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

Platform comparison

Market context

The Strait of Hormuz, through which roughly one-fifth of global seaborne oil transits, has experienced significant disruption since late 2023 owing to attacks on commercial vessels by Houthi forces and subsequent military responses. The IMF Portwatch metric tracks daily arrival counts across all major cargo categories; a 7-day moving average of 60 or above would represent a return to pre-disruption throughput levels. Current data shows transit calls well below that threshold, with recent weeks hovering in the 30–45 range, reflecting both direct attacks and the rerouting of vessels around the Cape of Good Hope—a costlier but safer alternative that has become standard practice for many operators.

Historical precedent suggests that normalisation in chokepoint traffic follows either a decisive security intervention or a negotiated settlement. The 1987–1988 Tanker War saw similar disruption; recovery took months after the US Navy's intervention. More recently, the 2019 Strait tensions resolved within weeks once diplomatic channels reopened. The current 1% probability reflects trader scepticism that a durable resolution—whether military, diplomatic, or through Houthi capability degradation—will materialise by May 2026, a timeframe of roughly 18 months from typical market creation.

Traders should monitor announcements from the US Central Command regarding operations in the Red Sea, any ceasefire negotiations involving Houthi representatives, and shipping insurance premium movements, which typically decline ahead of route normalisation. The UK P&I Club and Lloyd's of London regularly update war risk assessments; a downgrade would signal market confidence in corridor safety. Regulatory accessibility for this market depends on jurisdiction: German traders face GlüStV compliance requirements, whilst US CFTC reach extends to US persons regardless of location. Most prediction market platforms permit trading up to $1,500 notional without KYC verification, though this threshold varies by operator and does not exempt users from tax reporting obligations in their home jurisdiction.
