Because farmers are forced to plant with fewer inputs, crop yields are expected to drop over the next six to 12 months, resulting in global food shortages and severe inflation, as per ReliefWeb.

The warning breaks down the supply chain into a step-by-step crisis:

The Chokepoint

The Strait of Hormuz, a narrow waterway connecting the Arabian Gulf to the open ocean, acts as a global artery for both energy and agriculture. It facilitates the trade of up to of internationally traded fertilizers and a significant portion of the sulfur required to manufacture them, as per FAO

The Chain Reaction

Energy epikes: A prolonged closure drives up oil and gas prices. Energy is required to physically move and operate the global food system.

Input shortages: Ships carrying vital materials (like nitrogen and phosphate) remain idle. Farmers facing shortages or prohibitively high costs for these nutrients cannot maintain optimal soil fertility.

Reduced yields: With fewer agricultural inputs available, crop yields per acre drop. This particularly threatens staples like wheat, rice, and maize.

The 6-to-12-month lag

Because the world has some existing food reserves, a "buffer" period prevents immediate panic.

However, during this 6-to-12-month timeframe, planting seasons will inevitably pass without the necessary inputs, FAO warns.

When these lower-yield harvests materialize down the line, global food supplies tighten, culminating in skyrocketing retail food prices and widespread inflation.
