Iranian strategy has evolved from military strikes to economic warfare. Professor Mohammad Marandi, an adviser to Tehran, told Breaking Points the goal is to push the global economy toward a 1929-style depression. This approach uses control of the Strait of Hormuz as a lever. The immediate target is not just oil but the foundation of the global food system.
About 30% of globally traded fertilizer transits the strait. The disruption is more pernicious than the 2022 Ukraine crisis, argues Avantika Chilkoti on The Intelligence. That conflict involved direct sanctions on agricultural goods. Iran’s blockade targets farming inputs, not just harvests. Energy constitutes up to 50% of farm costs in rich nations. With planting seasons underway, some farmers are already leaving land fallow because fertilizer math no longer works.
“By maintaining control over the Strait of Hormuz, Iran can push the global economy toward a 1929-style depression.”

The physical shock is on a delayed fuse. Macro analyst Luke Gromen notes on Macro Voices that it takes roughly 45 days for a VLCC tanker to reach Asia from the Gulf. The last giant ship passed on February 28th. Its cargo won't arrive until mid-April. This creates a six-week air pocket in global energy supply that markets have not yet priced. Once the lag ends, the price spike will be nonlinear.
This strategy directly challenges US domestic politics. Iranian negotiators are using social media to taunt the Trump administration over $6-a-gallon gas, as reported on The Daily. The White House is betting its naval blockade will bankrupt Iran's Revolutionary Guard Corps before American voters revolt at the pump. The blockade itself is an act of war. It aims to intercept the 90% of Iranian oil bound for China.
“This isn't a speculative risk; it’s a math certainty.”

The fertilizer shortage creates a delayed humanitarian crisis. Gromen points to data showing half the world's population relies on synthetic fertilizer to survive. Missing the spring planting window in the Northern Hemisphere locks in harvest failures for 2027. Governments will then print money for food subsidies they cannot afford, triggering an inflationary feedback loop of currency devaluation and higher prices.
The long-term impact is structural. The Daily reports that even if the blockade ends, the Strait of Hormuz will never return to being a frictionless waterway. Global energy players are now seeking permanent overland pipelines to bypass the chokepoint. Iran has demonstrated that regional control is a weapon. The world is learning to function without the strait, permanently altering the geography of global trade.
