The United States military is moving to blockade the Strait of Hormuz following the collapse of peace talks between the U.S. and Iran in Pakistan. On April 12, President Donald Trump announced the country is fully locked and loaded, with the core breakdown centering on Iran’s nuclear ambitions, which the President identified as the primary dealbreaker in negotiations led by Vice President JD Vance. The story gained traction when reported by LADbible, which also detailed the projected economic fallout now being forecast by analysts.
U.S. Central Command subsequently clarified that naval forces will not impede freedom of navigation for vessels transiting to and from non-Iranian ports, meaning the blockade is targeted specifically at Iranian interests rather than constituting a full closure of the waterway. Iran’s military responded through state broadcaster Islamic Republic of Iran Broadcasting, warning that security in the Persian Gulf and the Sea of Oman is either for everyone or for no one, and that no port in the region will be safe.
Susannah Streeter, chief investment strategist at Wealth Club, said the push to force concessions from Iran has sent oil prices sharply higher. Fuel, food, utility bills, and housing costs are all projected to rise as a result, with analysts warning the combination risks pushing the economy into a period of stagflation, where prices climb even as growth stays flat.
The energy market was already under strain before the blockade announcement
The broader energy market had been under significant pressure before this latest development. According to the Short-Term Energy Outlook, global oil production was already constrained as storage facilities filled up in countries reliant on the Strait of Hormuz for exports. In March, Iraq, Saudi Arabia, Kuwait, the United Arab Emirates, Qatar, and Bahrain collectively shut in 7.5 million barrels per day of crude oil production, with analysts expecting that figure to climb to 9.1 million barrels per day throughout April.
Brent crude averaged $103 per barrel in March and is now forecast to peak at $115 per barrel in the second quarter of 2026. Retail gasoline prices are projected to hit a monthly average of nearly $4.30 per gallon in April, while diesel could exceed $5.80 per gallon due to tight global supplies and below-average U.S. inventories. The spread between Brent crude and West Texas Intermediate averaged $12 per barrel in March, driven by higher shipping costs and reduced oil flows from the Middle East to major Asian markets.
The FTSE 100 opened lower as markets absorbed the news of the failed talks and subsequent naval mobilization. The situation drew additional scrutiny given that Trump had also warned Beijing over weapons routed to Iran through third countries, adding another layer of geopolitical pressure on global markets.
The current two-week ceasefire is set to expire on April 22. Sir Keir Starmer has ruled out UK involvement in the blockade and stated his government is focused on keeping the Strait fully open, while Trump indicated other countries will join in policing the waterway without specifying which nations. Amid the escalation, US soldiers quietly leaving the military over the Iran war has added to concerns about military retention, with Pentagon figures pointing to a deepening strain.
