Iran on Monday mocked US President Donald Trump by ridiculing his blockade announcement earlier that day with a meme that said ‘Break an enemy blockade by blockading their blockade.’Along with the meme, Iran also took a dig at Trump by writing in his style. “I have, believe me, 100 percent, a PhD, okay? From the best college in the world. The best. Totally real. Everybody knows it. And frankly, you’re going to thank me, big time, for educating you. Nobody educates better than me,” it read. This comes after Trump’s threat to blockade the Strait of Hormuz following the collapse of talks with Iran over the weekend risks widening a conflict now entering its seventh week, driving up oil prices and raising fears of fresh global economic strain.The US military said it would begin blocking all maritime traffic to and from Iranian ports on Monday (Washington time), while allowing vessels to pass through the strait if they are not docking in Iran. Tehran swiftly rejected the move, with senior adviser Mohsen Rezaee warning that Iran “will not allow” such an embargo and retains “significant untapped leverage” to counter it.The escalation follows the breakdown of marathon negotiations in Pakistan, which had cast doubt over a fragile ceasefire agreed just days earlier. The talks—led by US vice president JD Vance and Iranian Parliament Speaker Mohammad Bagher Ghalibaf—collapsed over disagreements surrounding the future of Iran’s nuclear programme.Speaking on Sunday, Trump signalled indifference to reviving diplomacy, claiming Washington had already achieved key military objectives, including degrading Iran’s missile and drone capabilities.“If they don’t come back, I’m fine,” he said.Earlier, he struck a more aggressive tone, declaring the US was “locked and loaded” and ready to “finish up” what remained of Iran’s military capacity. He also warned of retaliation against any resistance, saying any attack on US forces or commercial vessels would be met with overwhelming force.The developments threaten to prolong a war that has already killed thousands and disrupted global energy markets. Oil and gas prices surged on Monday, with Brent crude jumping over 9% to near $104 a barrel, while European gas futures spiked sharply. Traders and refiners worldwide are scrambling to secure immediate crude supplies as physical flows tighten.The Strait of Hormuz—through which roughly a fifth of the world’s oil and liquefied natural gas passes—remains the most critical artery for global energy. A full blockade would severely constrict remaining shipments and intensify pressure on already volatile markets.According to Bloomberg, while blockades can be strategically decisive, their economic impact is rarely immediate. The current ceasefire is due to expire on April 22, though tensions threaten to unravel it sooner. Iran’s Islamic Revolutionary Guard Corps warned that any foreign military presence near the strait would be viewed as a violation.Since US and Israeli strikes began in late February, traffic through Hormuz has already slowed significantly, with Iran tightening control and imposing conditions on passage. While the US has the capability to enforce a blockade, analysts warn it carries serious risks—including direct exposure of American warships to Iranian missile and drone attacks, and the possibility of escalation involving Iran-backed groups such as the Houthis.With allies hesitant to join the operation and global markets on edge, the blockade threat itself may prove as consequential as any action on the water—raising the risk of miscalculation while narrowing the already shrinking space for diplomacy.
