Global Energy Markets Reel as Key Shipping Lane Disruption Sends Oil Prices Soaring Past Triple Digit Threshold

Table of Contents Oil prices experienced dramatic gains Monday following a US military declaration to blockade 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% approaching $104 per barrel. European natural gas contracts surged nearly 18% during peak trading. US crude similarly advanced more than 7%. The embargo targets all maritime traffic departing from or arriving at Iranian ports. Ships merely transiting through the Strait of Hormuz without Iranian port calls remain exempt from the blockade. US Central Command announced enforcement would commence at 10 a.m. Eastern Time Monday. The declaration followed the breakdown of diplomatic negotiations between Washington and Tehran in Islamabad during the weekend. BREAKING: President Trump is looking at resuming "limited military strikes" in Iran in addition to the US blockade of the Strait of Hormuz, per WSJ. Details include: 1. Trump could also resume a full-fledged bombing campaign, though officials said that was less likely 2. Trump… — The Kobeissi Letter (@KobeissiLetter) April 12, 2026 Vice President JD Vance headed the American negotiating team and departed Pakistan early Sunday morning after 21 hours of discussions yielded no breakthrough. Primary points of contention centered on Iran’s nuclear ambitions, restoration of passage through Hormuz, and Tehran’s backing of regional proxy organizations including Hezbollah. Tehran characterized American demands as “excessive.” Iranian officials indicated no intention to resume nuclear negotiations. President Trump stated to media: “I don’t care if they come back or not.” Mohsen Rezaee, Iran’s military adviser to the supreme leader, declared Iran “will not allow” the American embargo and possessed countermeasures to challenge it. The Strait of Hormuz has remained functionally closed following the initiation of coordinated US and Israeli strikes against Iran in late February. Iran had implemented transit fees on certain vessels and maintained traffic volumes at minimal levels compared to pre-conflict periods, effectively eliminating approximately 20% of world’s oil supply. Refineries and commodity traders globally are urgently pursuing immediately accessible crude shipments as physical availability contracts further. Market analysts suggest prices may climb substantially higher. Jorge Montepeque from Onyx Capital Group commented to Bloomberg TV that current valuations underestimate actual risk exposure. “It really makes no sense — it should be $140, $150,” he stated. Monday morning witnessed two fuel tankers attempting to navigate out of the Gulf through the Strait by maintaining close proximity to Iranian territorial waters — representing the initial vessels to make the attempt since the blockade announcement. Iran continued exporting crude oil and condensate from the Persian Gulf throughout March, with Chinese refiners representing the primary purchasers. Multiple vessels transporting oil designated for China now find themselves affected by the blockade. Former US Ambassador to Saudi Arabia Michael Ratney expressed apprehension regarding potential scenarios where US Navy forces intercept those vessels, cautioning about possible deterioration in US-China diplomatic relations. The Wall Street Journal disclosed 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 assessment later Monday.
