Iran Offers Hormuz Reopening for US Blockade End
US announces end of Iranian blockade by...?
Polymarket prices this March 31 at 75%. The reporting broadly agrees.
Iran has put forward a proposal to reopen the Strait of Hormuz within a week, contingent on the United States easing its naval blockade. This development comes after the United States reinstated its naval blockade targeting Iranian ships and their customers on July 13, 2026. Al Jazeera reported that mediated talks between the US and Iran at the UN General Assembly have focused on ending the conflict and opening the strategic waterway. The possibility of the US announcing an end to the blockade by March 31 has seen significant shifts, with traders currently putting the odds at 75%, reflecting a notable +0.5 pts change in the past 24 hours.
Background
The current tensions stem from the US decision to reinstate its naval blockade on Iranian vessels and their customers in July 2026, a move that significantly escalated the ongoing conflict. This blockade has severely impacted Iran's ability to conduct maritime trade, particularly concerning oil exports, and has led to a standoff over the vital Strait of Hormuz. The market has previously seen fluctuating odds regarding the duration of this blockade, reflecting the volatile nature of diplomatic efforts and military posturing between the two nations. The specific question at hand is whether the US will officially announce an end to this blockade by March 31.
The precedent
- The Strait of Hormuz is one of the world's most strategically important choke points for oil shipments, with approximately one-fifth of global oil consumption passing through it.
- The United States has previously imposed various sanctions and blockades on Iran, particularly concerning its nuclear program and maritime activities, dating back decades.

What to watch
The immediate focus will be on the diplomatic channels, particularly any further statements or actions following the UN General Assembly talks. A key indicator will be whether the United States formally responds to Iran's offer to reopen the Strait of Hormuz within seven days. Any official announcement from the US government regarding the lifting or suspension of the blockade would be the decisive factor. The ongoing negotiations and any signs of de-escalation will be closely monitored, especially as the December 31 resolution date for related markets approaches.
