Strait of Hormuz Crisis: US Imposes 20% Fee, Iran Strikes Back

US-Iran Conflict Escalates as Trump Declares US 'Guardian of the Strait'

The United States and Iran are locked in a dangerous military escalation after President Donald Trump announced a renewed naval blockade of the Strait of Hormuz and a 20% fee on all cargo passing through the strategic waterway. The crisis, which erupted on July 13, 2026, threatens to plunge the Middle East into a wider war and disrupt global oil supplies at a scale not seen since the 1970s oil shocks. The Strait of Hormuz crisis has already sent Brent crude oil prices surging to a one-month high of $85.27 per barrel on July 14, according to Trading Economics data.

Background: A Fragile Ceasefire Collapses

The current escalation follows a temporary ceasefire framework signed on June 18, 2026, which briefly halted hostilities after the US-Israeli campaign against Iran that began in late February. That campaign, which included the assassination of Supreme Leader Ayatollah Ali Khamenei, targeted nuclear facilities, missile sites, and military infrastructure. The truce unraveled after Iran attacked a container ship in the Strait of Hormuz, prompting the US to launch fresh strikes on approximately 140 targets across Iran.

On July 13, Trump announced via Truth Social that the US would reinstate a naval blockade of Iranian ports near the strait, with Central Command confirming the blockade would resume at 4 p.m. ET on July 14. The president declared the United States "THE GUARDIAN OF THE HORMUZ STRAIT" and said the US would charge a 20% fee on all cargo shipped through the waterway to cover security costs.

Iran Retaliates Across the Gulf

Iran's Islamic Revolutionary Guard Corps (IRGC) responded by launching missile and drone attacks targeting US-linked military facilities in Jordan, Kuwait, Oman, Qatar, Bahrain, and the UAE. Air defense systems were activated across the region. Reports indicate three people were injured in Qatar from falling debris, minor property damage in Jordan, and damage to an oil platform in Kuwait. Two UAE tankers were hit by Iranian cruise missiles in Omani waters, killing one Indian crew member.

Iranian Foreign Minister Abbas Araghchi responded defiantly, insisting that Iran, not the US, controls the strait. "Iran has always been the guardian of the strait," he said, adding that a 20% fee is "too much" and vowing to be "fair." The IRGC claimed it destroyed radar systems in Oman and hit targets in Jordan and Kuwait.

Houthis Join the Fight

Adding to the regional instability, Yemen's Houthi movement fired missiles at Saudi Arabia's Abha International Airport on July 13, breaking a four-year truce. The Houthis, who are backed by Iran, accused Saudi Arabia of bombing Sanaa International Airport to prevent an Iranian aircraft from landing. The group warned airlines to avoid Saudi airspace until restrictions on Sanaa airport are lifted, raising fears of renewed Red Sea shipping disruptions. The Houthi missile attacks on Saudi Arabia threaten to reopen a devastating conflict along the kingdom's southern border.

Global Oil Markets in Turmoil

The Strait of Hormuz is a critical chokepoint through which approximately 20% of the world's petroleum passes — roughly 20 million barrels per day. The renewed blockade has already slashed crossings by more than half. Brent crude futures rose 2% to $84.98 per barrel on July 14, following a 9.6% surge in the previous session — the largest daily gain since May 2020.

The Dallas Federal Reserve estimates that a closure lasting one quarter could raise West Texas Intermediate oil prices to $98 per barrel and lower global GDP growth by an annualized 2.9 percentage points. The World Bank described the disruption as the largest oil market shock in history, with global oil supply crashing by 10.1 million barrels per day in March 2026. The International Energy Agency (IEA) has already coordinated a record release of 400 million barrels from strategic petroleum reserves across 30 nations, but analysts warn this may not be sufficient if the blockade persists.

Legal and Diplomatic Fallout

International maritime law experts have questioned the legality of Trump's proposed fee. James Kraska, a professor of international maritime law, noted that while voluntary convoy protection fees could be legal, a compulsory 20% toll on all cargo has no basis in international law. The UN's International Maritime Organization has stated that charging fees for passage through international straits violates the UN Convention on the Law of the Sea.

The UN Security Council held an emergency meeting on July 2 to address the escalating crisis, with UN Secretary-General António Guterres condemning the escalation and warning of "catastrophic consequences." The UN also reported that the International Atomic Energy Agency (IAEA) has "lost continuity of knowledge" across all of Iran's declared nuclear facilities since the US-Israeli strikes began, raising serious proliferation concerns. The IAEA lost continuity of knowledge in Iran undermines international non-proliferation efforts.

What's Next?

As of July 14, 2026, the situation remains highly volatile. Trump has left the door open for negotiations, stating the ceasefire is effectively over but that talks could resume. However, with both sides entrenched in their positions and regional actors being drawn into the conflict, the risk of a wider war — and a prolonged disruption to global energy supplies — remains acute. The coming days will be critical in determining whether diplomacy can prevail or the world faces a new era of conflict in the Persian Gulf.
