Iran rejects Trump’s deadline to open Strait of Hormuz

Trump’s Ultimatum and Iran’s Response

President Donald Trump escalated diplomatic pressure on Iran by imposing a strict deadline for the opening of the Strait of Hormuz, warning of potential military strikes if Tehran failed to comply. During a televised address on April 6, 2026, Trump stated the strait would be opened by Tuesday at 8 p.m. ET, or else the U.S. would target Iran’s power plants and bridges. This demand followed Iran’s rejection of ceasefire proposals and its continued blockade of the strait, which contributed to a 20–30% rise in global energy prices. U.S. crude prices reached $115.48 per barrel, according to market data. Iranian officials, including President Seyyed Mehdi Tabatabai, dismissed Trump’s ultimatum as a demonstration of ‘desperation and anger’, insisting the strait would only be opened after Iran received ‘compensation through a new legal regime’ tied to transit fees. This position reflects Iran’s strategy of leveraging the strait’s economic importance to pressure the U.S. into concessions.

The Strategic Significance of the Strait

The Strait of Hormuz is a critical maritime chokepoint, serving as the sole sea passage between the Persian Gulf and the open ocean. Data from the U.S. Energy Information Administration (EIA) indicates the strait accounts for approximately 20% of global LNG trade and 25% of seaborne oil trade annually. Its narrow width—ranging from 24 to 60 miles at its narrowest—means even a temporary closure could disrupt millions of barrels of oil per day, affecting global supply chains. During the 2026 Iran War, the strait’s strategic value became a focal point of the conflict, with Iran using its control over the waterway to exert pressure on the U.S. and its allies.

Economic Leverage and Regional Impact

The strait’s economic significance is further amplified by its role in energy security for major importers like China, which relies on the strait for nearly half of its crude oil imports, and Qatar, which exports 90% of its LNG through the route. It is also critical to Europe’s energy security, as it provides the only maritime route for several Gulf countries including Qatar, Kuwait, and Bahrain. The closure of the strait during the conflict led to a sharp spike in global energy prices, with U.S. crude prices reaching $115.48 per barrel—a 20–30% increase compared to pre-conflict levels. This economic leverage has allowed Iran to position itself as a key player in the region, using the strait as both a weapon and a bargaining chip in its dealings with the U.S. and other global powers.

Escalating Military Actions

Military actions have intensified, with both the U.S. and Iran escalating operations. Israel confirmed the killing of Iran’s Revolutionary Guard Corps intelligence chief, Majid Khadami, in airstrikes, underscoring the growing militarization of the region. The U.S. and Israel have also targeted Iran’s petrochemical and steel facilities, disrupting missile production and damaging key infrastructure. These strikes have significantly impacted Iran’s energy sector, with reports of damage to the South Pars Gas Field and the Marvdasht industrial estate, critical to Iran’s oil and gas production.

Iran’s Retaliatory Strikes

In response, Iran launched missile and drone attacks on Israeli towns, oil refineries in the Gulf, and infrastructure in Kuwait and the UAE, causing casualties and significant damage. Houthi militants, backed by Iran and operating from Yemen, warned of potential attacks on the Bab al-Mandeb Strait, a critical global trade route. Aliakbar Velayati, an Iranian adviser, compared the strategic value of the Bab al-Mandeb Strait to that of the Hormuz Strait, warning that targeting it could disrupt global energy and trade. These military actions have deepened the crisis, with regional powers grappling with the humanitarian and economic fallout of the escalating conflict.

Diplomatic Efforts and Regional Mediation

Diplomatic efforts have been led by regional powers and international mediators. Egyptian, Pakistani, and Turkish envoys submitted a 45-day ceasefire proposal to Iran and U.S. officials, aiming to stabilize the crisis and prevent further escalation. Qatar’s leadership has emphasized coordination to ensure energy security and regional stability, while Oman’s Foreign Ministry highlighted discussions on ensuring smooth passage through the Strait of Hormuz. These initiatives reflect growing concerns among regional actors about the potential for a broader conflict that could destabilize the entire Middle East. However, Iran’s insistence on a ‘new legal regime’ for the strait’s transit fees has complicated negotiations, as the U.S. and its allies view such demands as an attempt to extract economic concessions. The involvement of external powers like Russia and China, which have expressed interest in mediating the crisis, adds complexity to the diplomatic landscape. Without progress in negotiations, the risk of further military confrontations—and their devastating consequences—remains high.

The Vulnerability of the Strait

The Strait of Hormuz is 104 miles long, with a width varying from about 24 to 60 miles at its narrowest points. This narrow passage makes it one of the most vulnerable chokepoints in global maritime trade. While alternative routes such as the Goreh-Jask pipeline exist, their capacity and usage remain limited. The Goreh-Jask pipeline has a capacity of ~300,000 barrels per day but saw minimal usage (<70,000 barrels per day in summer 2024) and stopped exports by September 2024. This underscores the strait’s irreplaceable role in global energy markets and the precariousness of its current status. The lack of viable alternatives means that any prolonged closure of the strait would have catastrophic effects on global energy supply chains.

U.S. Energy Imports and Strategic Investments

The U.S. Energy Information Administration (EIA) reported that the strait accounted for 0.5 million barrels per day of U.S. crude and condensate imports during the 2023–2025 period, representing a 40-year low due to increased domestic production. The U.S. military’s presence in the region, combined with its strategic investments in securing the strait, highlights the broader geopolitical stakes of the conflict. These actions have also raised concerns about the potential for further escalation, as both sides continue to test each other’s resolve.
