Trump announces US blockade of Hormuz lifted by 2026?

Market context

On 12 April 2026, President Trump announced a United States blockade of the Strait of Hormuz, a critical chokepoint through which roughly one-third of global seaborne oil transits. This market tests whether Trump or his administration will publicly declare an end to that blockade by 30 June 2026—a window of approximately 2.5 months from announcement. The crowd currently prices a 35% chance of such an announcement occurring, implying traders view a sustained blockade as the base case through mid-year.

Historical precedent suggests blockades of major shipping lanes rarely reverse quickly once implemented. The Cuban Missile Crisis lasted thirteen days before resolution; the 1973 Arab oil embargo persisted for five months; more recently, the Suez Canal blockage in March 2021 lasted nine days but required major diplomatic and financial concessions. Trump's previous Iran policy (2018–2021) involved maximum-pressure sanctions that took years to unwind, and reversals typically required either significant geopolitical shifts, economic pain thresholds being breached, or negotiated settlements. A two-and-a-half-month resolution window is compressed relative to these historical timescales.

Traders should monitor statements from the Iranian government regarding negotiations, oil price movements (sustained spikes above $120/barrel typically trigger political pressure for relief), and any public signals from Trump regarding deal-making progress. Congressional responses and statements from Gulf allies—particularly Saudi Arabia and the UAE—will indicate whether domestic or regional pressure is building for a reversal. Official announcements from the Department of Defense or State Department clarifying blockade scope or duration would constitute material catalyst events.
