Global fertiliser disruption threatens food security as Iran conflict blocks key shipping lanes

The ongoing hostilities between the United States, Israel and Iran have severely disrupted global agricultural supply chains by blocking shipping through the strategic Strait of Hormuz. Svein Tore Holsether, chief executive of Yara, one of the world's largest fertiliser producers, states that this interruption has caused fertiliser prices to soar by 80% since the conflict began. The closure of this critical chokepoint, through which approximately a third of global fertiliser traffic normally passes, has created immediate bottlenecks for essential inputs including urea, potash, ammonia and phosphates.

According to Holsether, the shortage of nitrogen fertiliser is currently preventing the production of around 500,000 tons globally. He warns that this reduction in input availability could slash global crop yields by up to 50% in the first season, equating to a loss of up to 10 billion meals every week. The fertiliser market is highly interconnected, meaning that disruptions in the Gulf are rapidly affecting destinations across Asia, South East Asia, Africa and Latin America. Holsether notes that regions already suffering from under-fertilisation, such as several countries in sub-Saharan Africa, face the prospect of significant drops in crop yields that could exceed the global average.

While the United Kingdom is unlikely to face immediate food shortages, the economic pressure on producers is expected to translate into higher consumer bills within the coming months. The Food and Drink Federation forecasts that food inflation could reach 10 per cent by December, with the Bank of England predicting a rise to 4.6 per cent in September. Farmers worldwide are currently squeezed by rising costs for energy, diesel and fertiliser without corresponding increases in the prices they can command for their produce. This financial strain threatens to reduce the volume of food available to the market even if physical stocks remain stable.

The consequences for Asian food markets will not be fully visible until the end of the year, when harvests planted this spring fail to materialise or arrive in smaller quantities. Professor Paul Teng, a senior fellow in food security in Singapore, indicates that while some nations may manage their immediate planting seasons, a prolonged crisis will inevitably impact rice crops in the coming months. Analysts suggest that the delay in price reflection for Asian consumers masks the severity of the situation, as the failure of spring harvests will only emerge later in the year.

The United Nations estimates that the combined fallout from the Middle East conflict could push an additional 45 million people into acute hunger by 2026. Food insecurity in the Asia-Pacific region is expected to rise by 24 per cent, representing the largest relative increase of any global region. Holsether cautions that a continuation of the conflict could trigger a bidding war for food between richer and poorer nations, leaving the most vulnerable populations in developing countries to pay the highest price for basic sustenance.
