Iran's Ghalibaf Declares Military Readiness Amid Renewed Strait of Hormuz Closure

The closure of the Strait of Hormuz disrupts approximately 21 million barrels of oil transit daily, affecting global supply chains and prices.

• On April 18, 2026, Iranian Parliament Speaker Mohammad Bagher Ghalibaf declared no trust in the U.S. and confirmed full military readiness amid rising tensions.
• Iran re-closed the Strait of Hormuz in response to a persistent U.S. naval blockade, impacting global oil transit.
• The ongoing conflict, termed the 'third imposed war,' escalated following U.S. and Israeli strikes on Iranian targets, leading to immediate Iranian counterstrikes.

• The 2026 Iran war began on February 28, 2026, with U.S. and Israeli military actions against Iran, prompting Iranian retaliation.
• The Strait of Hormuz is a critical chokepoint for global oil, with about 20% of the world's oil supply passing through it.
• Iran's military capabilities have reportedly strengthened, with the Islamic Revolutionary Guard Corps (IRGC) asserting control over the Strait following drone and missile engagements.

The recent declaration by Ghalibaf is a culmination of escalating tensions that have defined the 2026 Iran war, which began with U.S. and Israeli strikes on Iranian military targets. This conflict has been characterized by rapid military responses from Iran, including the downing of approximately 180 drones, showcasing its enhanced defensive capabilities. The closure of the Strait of Hormuz, a vital artery for global oil transport, is a strategic move by Iran to assert its power and retaliate against what it perceives as U.S. aggression.

The U.S. blockade on Iranian ports has been a significant factor in this standoff, leading to Iran's decision to re-close the Strait after a brief reopening that followed a temporary ceasefire. This ceasefire was only possible due to partial progress in nuclear negotiations, mediated by countries like Pakistan. However, the U.S. violations of this ceasefire have led to renewed hostilities, with Ghalibaf's address emphasizing Iran's readiness to respond to any perceived threats.

The implications of this situation extend beyond military posturing; they resonate deeply within global oil markets. With the Strait of Hormuz re-closed, oil prices have surged, with Brent crude surpassing $120 per barrel. This spike in prices is not just a reflection of immediate supply concerns but also a signal of the broader geopolitical instability that could affect energy security worldwide. The economic ramifications are already being felt in regions like Dubai, where stock markets have lost significant value, and inflation risks are rising due to volatile fuel prices.

Moreover, Ghalibaf's rhetoric indicates a shift in Iran's approach to negotiations, framing them as tools of confrontation rather than dialogue. This could lead to a prolonged period of instability, as Iran continues to assert its military readiness while rejecting U.S. negotiation tactics. The IRGC's control over the Strait and its readiness to retaliate against any threats further complicate the landscape, making it clear that the conflict is far from over.
