- The naval blockade comes after weekend ceasefire negotiations between the US and Iran in Pakistan ended without agreement

Oil prices experienced a dramatic surge Monday following Washington’s declaration that it would implement a naval blockade against all commercial vessels conducting trade with Iran, pushing Brent crude beyond the $100 per barrel threshold for the first time in recent months.
Brent futures climbed as high as 9.1% to reach nearly $104 per barrel. European natural gas markets saw prices spike almost 18% during peak trading. US crude similarly increased more than 7%.
The embargo targets all commercial shipping entering or departing Iranian harbors. Vessels simply transiting through the Strait of Hormuz without Iranian port calls are exempt from the restrictions.
US Central Command confirmed enforcement operations would commence at 10 a.m. Eastern time Monday. The directive followed the collapse of diplomatic negotiations between Washington and Tehran held in Islamabad during the weekend.
Vice President JD Vance headed the American negotiating team and departed Pakistan early Sunday after 21 hours of intensive discussions failed to yield a breakthrough. Primary disagreements centered on Iran’s nuclear activities, restoration of access through Hormuz, and Tehran’s backing of regional proxy organizations including Hezbollah.
Iranian officials characterized US demands as “excessive.” Tehran indicated no interest in resuming nuclear discussions. President Trump responded to journalists: “I don’t care if they come back or not.”
Mohsen Rezaee, Iran’s military adviser to the supreme leader, stated Iran “will not allow” the US embargo and possessed means to resist it.
The Strait of Hormuz had already been essentially non-operational since late February when US and Israeli military strikes against Iran initiated. Iran had been levying passage fees on certain vessels and maintaining traffic at minimal levels compared to pre-conflict volumes, eliminating approximately 20% of the world’s oil supply.
Global Supply Disruption
Refineries and commodity traders worldwide are now rushing to secure immediately available crude shipments as physical supply availability contracts further.
Several market analysts predict prices could climb considerably higher. Jorge Montepeque of Onyx Capital Group stated on Bloomberg TV that markets are underestimating the risk. “It really makes no sense — it should be $140, $150,” he commented.
Monday morning witnessed two petroleum tankers attempting to exit the Gulf through the Strait by navigating near Iran’s territorial waters — representing the first vessels to make the attempt since the blockade announcement.
Beijing’s Involvement
Iran continued exporting crude and condensate from the Persian Gulf throughout March, with China serving as the primary recipient. Multiple tankers carrying oil destined for Chinese refineries are now affected by the blockade.
Former US Ambassador to Saudi Arabia Michael Ratney expressed alarm about potential confrontations if US Naval forces move to intercept those vessels, cautioning about possible escalation in US-China diplomatic relations.
The Wall Street Journal published reports that Middle Eastern governments were working to facilitate renewed ceasefire discussions between Washington and Tehran in upcoming days.
OPEC is scheduled to release its monthly market analysis later Monday.
