Trump ordered a US naval blockade on Iran linked ships in Hormuz, Iran retaliated by closing the waterway, crippling oil flows and spiking Brent crude. News18 explains the crisis

The Strait of Hormuz has entered a state of near-total paralysis. United States President Donald Trump’s imposition of a US naval blockade on Iran-linked ships has combined with Iran’s retaliatory closure of the waterway to create what experts call a “dual blockade".

News18 explains the historic shipping crisis.

The State of the Strait

Daily commercial transits have dropped from a peacetime average of 135 to nearly zero. Approximately 20,000 seafarers and hundreds of ships are currently stranded within the Persian Gulf.

Crude output from the region has plummeted by 57%, causing Brent crude prices to peak at $126 per barrel in March 2026, according to Bloomberg.

Evolution of the Blockade

The crisis escalated rapidly following the start of the U.S.-Israel air war against Iran on February 28, 2026:

Iran first restricted traffic in retaliation for airstrikes, using its “mosquito fleet" of gunboats to harass and seize vessels.

In mid-April, President Trump ordered a U.S. blockade to prevent Iran from exporting oil. On April 17, after Iran briefly declared the strait “completely open," Trump posted on Truth Social that the U.S. blockade would remain, leading Iran to immediately reimpose its own restrictions.

Conflict has moved beyond the strait; the U.S. Navy and Iranian forces have engaged in seizures as far away as the Arabian Sea and waters east of Sri Lanka.

What does the blockade entail?

Targeted Enforcement: While President Trump initially called for a blockade of “any and all" ships in the strait, CENTCOM clarified that it applies specifically to vessels entering or departing Iranian ports.

Maritime Interdiction: US forces (including the US Navy and Air Force) are authorised to board, search, and seize ships suspected of carrying Iranian cargo or providing material support to Iran.

“Shoot and Kill" Orders: Trump has ordered the Navy to “shoot and kill" any Iranian vessels caught laying naval mines in the strait.

Fee Interception: The US military seeks to intercept any vessels in international waters that have paid transit fees or “tolls" to Iran, which Iran had been charging at rates up to $2 million per ship.

Minesweeping Operations: US forces have begun clearing naval mines allegedly placed by Iran to maintain what they call a “safe pathway" for non-Iranian traffic, according to Al Jazeera and other reports.

Global Market Impacts

The blockade has triggered the largest disruption to world energy since the 1970s.

• Energy: 25% of seaborne oil and 20% of global liquefied natural gas (LNG) pass through Hormuz annually; these flows are now largely halted.
• Agriculture: The region accounts for 30-35% of global urea exports. The shutdown is expected to create severe fertilizer shortages and spike food prices through the end of 2026.
• Logistics: Shipping firms are paying record premiums—up to $4 million—to bypass the chaos by using alternative routes like the Panama Canal, despite surging auction prices.

Shipping executives warn that even if a diplomatic breakthrough occurs today, a return to “normal" operations is likely months away due to the logistical backlog and the threat of sea mines.

KEY FAQS

Why is the Strait of Hormuz so important?

The Strait of Hormuz is one of the world’s most critical chokepoints. A large share of global oil and gas shipments passes through it, so any disruption quickly impacts energy prices and global trade routes.

What impact would a blockade have on shipping?

A blockade would force tankers and cargo ships to reroute or delay voyages, driving up freight costs, insurance premiums, and delivery times. This creates ripple effects across supply chains—from fuel to everyday goods.

Why does this deepen a “historic" shipping crisis?

Global shipping is already strained by conflicts, congestion, and rising costs. A disruption at Hormuz adds another major bottleneck, compounding delays and making an already fragile system even more unstable.
