The severity of El Niño's impact stems from the simultaneity of disruptions across many regions. A single supply chain shock is manageable, but dozens happening at once overwhelm market forces and capital allocation, leading to a system-wide depression of growth.

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.

Despite El Niño being a predictable phenomenon for centuries, its ability to inflict trillions in economic damage demonstrates a widespread failure to adapt. This suggests societies are not resilient even to existing climate variability, let alone future changes.

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.

Previous models measuring climate event costs as one-time "level effects" were vastly wrong. By accounting for the permanent depression of economic growth, the 1997-98 El Niño's five-year cost was actually $5.7 trillion, over 150 times higher than prior estimates.

The current El Niño is not just a stronger version of past events; it's occurring in a world with significant background global warming. This combination makes it a truly novel phenomenon whose consequences are harder to predict, with damages estimated near $10 trillion.

Contrary to belief that economies rebound from weather shocks, research shows El Niño systematically lowers a country's growth *trajectory*. The damage is not a one-time level effect but a persistent drag, causing economic losses to compound over time.

Beyond typical macro factors, the Super El Niño is a major risk for frontier markets that rely heavily on domestic food production. Adverse weather could spike food and headline inflation, potentially forcing central bank action and putting upward pressure on bond yields, leading to a more neutral stance on rates.

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.
