Strait of Hormuz Traffic Unlikely to Normalize by Year-End Amid Persistent Regional Conflict

A Polymarket prediction market shows overwhelming doubt that Strait of Hormuz shipping traffic will return to a 7-day moving average of 60 transit calls by December 31, 2026, reflecting ongoing severe disruptions from geopolitical tensions and naval blockades throughout the year.

The critical Strait of Hormuz, a vital chokepoint for global energy and trade, has been gripped by severe disruptions throughout 2026, leading to a strong market consensus that normal shipping traffic will not resume by December 31. A Polymarket prediction market, asking if the IMF Portwatch 7-day moving average of transit calls will reach or exceed 60, currently shows a 'No' outcome trading at 0.905 (90.5% implied probability), underscoring the market's bearish outlook.

Historically, the Strait of Hormuz sees between 88 and 153 transit calls daily, facilitating nearly 20% of global oil and a significant share of LNG exports. However, this normalcy shattered on February 28, 2026, following joint U.S.-Israeli strikes on Iran. Iran retaliated by issuing warnings, boarding merchant ships, and deploying sea mines, effectively closing the strait to most commercial shipping.

The impact on maritime traffic was immediate and drastic. IMF Portwatch data, the market's resolution source, recorded a collapse from an average of 89.4 transits per day in February to just 4.8 per day in March. By July, the daily average had only partially recovered to 18.2 transits. Al Jazeera reported an even starker decline by August, with traffic plummeting from over 100 vessels daily to merely five. Overall, commercial transits dropped by approximately 90% compared to pre-conflict levels.

Further complicating the situation, the United States imposed a naval blockade on Iran starting April 13, 2026, which was reinstated on July 14, 2026. This blockade has severely constrained Iranian oil exports and compounded the reduction in overall shipping volume through the strait. As recently as November 6, 2026, the maritime security environment in the region was described as "highly volatile," with Iranian attacks on commercial shipping continuing and the U.S. blockade still in effect.

The ongoing Houthi attacks in the Red Sea, which intensified again in July 2026, have created a dual chokepoint crisis, forcing many major carriers to reroute around the Cape of Good Hope and further exacerbating regional instability. This widespread disruption has led to a surge in war risk insurance premiums, spiking by up to 1,000% and making transit prohibitively expensive for most commercial operators.

While some U.S.-facilitated transits have been reported, averaging around 31.5 vessels per day in early November, this figure remains far below the 60-call threshold required for the 'Yes' outcome. Given the persistent geopolitical tensions, active blockades, and the extremely low current traffic levels reported by IMF Portwatch, the market's strong conviction that normal traffic will not return by year-end appears well-founded. The significant investment in the 'No' outcome ($15,869,460 out of a total trading volume of $17,539,960) reflects a deep-seated expectation of continued maritime insecurity and depressed shipping activity in the Strait of Hormuz for the foreseeable future.
