Strait of Hormuz Shipping Market Poised for 'No' as Traffic Remains Severely Disrupted

A Polymarket prediction market betting on the return of Strait of Hormuz shipping traffic to pre-conflict levels by April 30, 2026, is overwhelmingly priced for a 'No' resolution, reflecting the dire reality of ongoing geopolitical tensions and blockades.

The Polymarket prediction market, titled 'Strait of Hormuz traffic returns to normal by end of April?', is currently trading with an overwhelming 99.55% probability for a 'No' resolution. This market is set to resolve 'Yes' only if the IMF Portwatch publishes a 7-day moving average of transit calls for the Strait of Hormuz equal to or above 60 for any date between its creation and April 30, 2026. The current market odds strongly reflect the severe and sustained disruption to maritime traffic in this critical global chokepoint.

Market Significance Amidst Geopolitical Turmoil

The Strait of Hormuz, a narrow waterway connecting the Persian Gulf to the open ocean, is globally significant, typically handling approximately 25% of the world's seaborne oil trade and 20% of its liquefied natural gas (LNG). The market's resolution hinges on the recovery of transit calls, which include container, dry bulk, roll-on/roll-off, general cargo, and tanker ships, as reported by IMF Portwatch. The current low volume of trading activity, at just over $30 million, suggests a high degree of consensus among participants regarding the market's likely outcome.

Recent Developments Point to Continued Disruption

The drastic decline in shipping activity stems from the ongoing "Iran War," which commenced on February 28, 2026, following U.S. and Israeli strikes against Iran and subsequent Iranian retaliations. Since then, Iran has largely blocked the strait, leading to attacks on merchant ships and the reported laying of sea mines. Further escalating the crisis, the U.S. implemented a blockade of Iranian ports starting April 13, creating a "dual blockade" scenario.

IMF Portwatch data, the market's resolution source, reveals a dramatic drop in traffic. Prior to the conflict, the Strait saw an average of 84 to 100 ships daily. However, between March 1 and April 12, the daily average plummeted to a mere 6 to 7 ships. Even a brief two-week ceasefire declared on April 8 offered little respite, with transit calls only modestly increasing to an average of 10.1 ships per day between April 8 and April 19. While there was a slight rebound to 19 vessels transiting on April 25, this remains drastically below the 60-ship threshold required for a 'Yes' resolution. As of April 25, shipping traffic remained 88.0% below pre-conflict averages.

Attempts to reopen the strait have been short-lived and fraught with danger. Iran's declaration of an open strait on April 17 was reversed just one day later, leading to tankers turning back and reports of gunfire in the waterway. On April 22, Iran further exacerbated tensions by seizing two container ships.

Bleak Outlook for a Return to Normalcy

Experts and shipping industry stakeholders do not foresee a swift return to normal operations. Normal shipping activity is considered unlikely until a sustained period of peace, the restoration of commercial permissions from insurers, and a resurgence of operational and human confidence are achieved. Such a recovery could take an estimated 4 to 16 weeks. Major shipping lines continue to refuse bookings for cargo through Hormuz, largely due to the absence of war-risk insurance, even during periods when the strait was declared partially open. This has left hundreds of vessels stranded and impacted an estimated 20,000 seafarers.

The ongoing Red Sea shipping crisis, driven by Houthi attacks, further compounds regional maritime instability, though the disruption in the Strait of Hormuz is distinct due to the fundamental logistical challenges in rerouting very large crude carriers (VLCCs) and LNG tankers. The confluence of these factors has already led to sharp increases in global commodity prices, particularly for crude oil and fertilizers.

Given the current daily transit call averages well below the 60-ship threshold, coupled with persistent geopolitical tensions and a mere three days remaining until the market's resolution on April 30, it is highly improbable that the 7-day moving average will reach the required level. The market's strong lean towards 'No' is a direct reflection of these entrenched realities.
