Iran's Revolutionary Guard vowed to block all oil and gas shipments through the Strait of Hormuz on Monday during a surge in military conflict.

This escalation threatens global energy markets because approximately 20% [3] of the world’s oil passes through the narrow waterway. Any prolonged disruption could trigger a sharp increase in international fuel prices and destabilize regional trade.

The threat comes as the U.S. Central Command carried out its nine [1] consecutive nights of air strikes against targets in Iran. U.S. assets operated from the region, including an aircraft over Jordan, to target Iranian sites. The U.S. said the strikes are intended to hold Iran accountable for its aggression and restore freedom of navigation.

In response, a Revolutionary Guard spokesperson said, "We will not allow a single drop of oil or gas to pass through the Strait of Hormuz."

Iran's joint military command further warned that all oil tankers moving through the strait must use approved routes or face a "forceful response." While some reports indicate Iran stopped two [2] tankers in the strait, other accounts focus on the warnings issued to shipping companies.

Iran is leveraging the strategic waterway to pressure the U.S. and its allies. The Revolutionary Guard has utilized the strait as a primary tool for asymmetric leverage against Western naval presence in the Persian Gulf.

The U.S. continues to maintain its operational tempo in the region to counter Iranian influence and ensure the security of commercial shipping lanes. The current cycle of strikes marks a significant escalation in the direct military confrontation between the two nations.

"We will not allow a single drop of oil or gas to pass through the Strait of Hormuz."

The convergence of U.S. kinetic strikes and Iranian threats to close the Strait of Hormuz creates a high-risk environment for global energy security. By threatening the world's most critical oil transit chokepoint, Iran is attempting to shift the cost of the conflict from its own military infrastructure to the global economy, forcing international pressure on the U.S. to cease its bombing campaign.
