The Hormuz closure is disrupting fertilizer supply chains during the Northern Hemisphere's planting season. This ensures lower crop yields, creating a significant and unavoidable food inflation shock that will hit the global economy 6-12 months from now, after the harvest season.

The upcoming strong El Niño is not an isolated climate event but a potent amplifier of existing global problems. It is expected to exacerbate food insecurity in the Global South, a region already suffering from fertilizer shortages and supply chain issues caused by geopolitical conflicts like the war in Iran.

The world faces two simultaneous, unrelated threats to food security. Geopolitical conflict is disrupting fertilizer supplies needed for crop yields, while the El Niño climate pattern is predicted to bring droughts and extreme weather to vulnerable agricultural regions. The combination creates a compounding crisis that could be catastrophic.

The current disruption to time-sensitive fertilizer supply chains has already locked in lower crop yields globally. This will translate directly into rising food prices and a high probability of political instability in emerging markets, echoing the start of the Arab Spring.

Unprecedented ocean temperatures are fueling a Super El Niño. The resulting atmospheric energy release will cause extreme weather, leading to predictable crop failures in key agricultural regions like Brazil, Australia, and India. This may create severe food shortages and economic instability over the next 12 months.

In the 1970s, food inflation had a greater impact on CPI than energy. A similar pattern is emerging now, as the Strait of Hormuz disruption hits key fertilizer inputs like urea and sulfur. This creates a reliable six-month leading indicator for a major surge in food prices that markets are currently ignoring.

A significant shift is occurring where EM central banks, like in South Africa and Korea, are turning hawkish pre-emptively to combat inflation. This is happening even without the typical trigger of currency depreciation, indicating a proactive policy response to the inflation-growth mix rather than a reactive move to provide risk premia for a weakening currency.

Beyond traditional economic factors, climate change creates persistent inflationary pressure. Its impact on harvests drives up food and commodity prices, while increased natural disasters raise insurance and reinsurance rates. This is a crucial, often overlooked, long-term factor in macro analysis.

Despite its predictable patterns, the net economic effect of an El Niño year is profoundly uncertain. Economic models vary wildly, with some studies suggesting a neutral impact on global GDP while others predict losses on the order of several trillion dollars, highlighting the difficulty of forecasting the consequences of complex climate events.
