Projected Loss: Experts estimate that a total blockade could strip Iran of $25 billion to $35 billion in annual oil revenue.

Budget Deficit: With oil accounting for a massive portion of the state budget, the government would struggle to pay civil servant salaries and fund its internal security apparatus.
2. Food Security and Social Unrest
Iran is not self-sufficient in several critical food categories. The country imports millions of tons of soybeans, corn, and vegetable oils annually.

The Price of Isolation: Cutting off sea routes would force Iran to rely on overland trade through Turkey or Iraq—routes that are significantly more expensive and lower in capacity.
-
Inflationary Pressure: The cost of basic staples could double within weeks, potentially sparking widespread social unrest similar to the protests seen in previous years.
3. The Collapse of the Non-Oil Sector
Iran has spent the last decade trying to diversify its economy through petrochemicals, steel, and mining. However, these industries require heavy maritime shipping for export.
“A blockade isn’t just about stopping what comes in; it’s about trapping what’s inside,” says a Middle East trade analyst. “Iran’s warehouses would overflow with products that have no buyers, leading to massive layoffs in the industrial heartlands.”
