In late July 2024 Australian officials warned that the country's fertilizer supply was becoming vulnerable to geopolitical shocks. The Australian Fertiliser Corporation highlighted the risk of sustained Houthi attacks on Red Sea shipping and Iran's blockade of the Strait of Hormuz, which could lengthen transit times and raise freight costs for ammonium phosphate and super‑phosphate. At the same time, global phosphate prices hovered near US$900 per tonne because of severe sulphuric‑acid shortages linked to Persian Gulf hostilities, prompting a A$160 million loan to support the Phosphate Hill plant.

Growers responded by exploring on‑farm storage options for urea and visiting Koch Fertiliser Australia's Brisbane facility to assess sheds and silos, reflecting recent price volatility and the perception that similar supply shocks could recur. Analysts broadened the view, describing fertiliser as a strategic commodity whose supply chain is exposed to conflicts such as the Ukraine war, sanctions on Belarusian potash, and tensions near the Strait of Hormuz.

A new analysis dated 5 August 2026 warned that the Strait of Hormuz is a critical global chokepoint: its closure pushed urea prices up 60‑70%, affected roughly 30% of world urea output, and raised ammonia and phosphorus prices by 20‑30%. Saudi Arabia’s road rerouting of product added cost, while emerging sulphur shortages further strained supply. The report underscored that these Middle‑East freight disruptions pose a significant risk to Australian fertilizer imports and the broader agricultural sector.
