Money Managers Brace for Historic 'Super' El Niño as Climate Risks Rattle Global Markets

Economists and investors are preparing for what is expected to be the most extreme El Niño cycle in history, revising inflation and deficit estimates as droughts, floods, and rising food prices threaten global asset markets.

Money managers and economists are preparing for a potential "super" El Niño cycle that is widely expected to be the most extreme in recorded history. The climate phenomenon, which originates in the Equatorial Pacific Ocean, is already causing crop-damaging droughts and floods that disrupt agriculture, raise food commodity prices, and force revisions to inflation and deficit estimates worldwide.

Katie Self, a portfolio manager at Pictet Asset Management, which oversees the US$5.1 billion Pictet Global Environmental Opportunities fund, stated that it has become almost a full-on certainty that this will be the most extreme El Niño in history. Economists are now revising their estimates for inflation and deficits due to the prospect of this unprecedented weather cycle.

Investors warn that no global asset market will be fully shielded from these effects, particularly given existing stresses such as high debt levels and rising interest rates. In July, Man Group warned that grid infrastructure, metals, and fertilizer could be impacted by El Niño. To protect its US$165 billion portfolio of emerging-market debt and equities, T. Rowe Price has turned to custom-made models designed to account for the climate event's financial fallout.

Analysts Kamesh Korangi and Rose Choy identified Indonesia, Brazil, and Colombia as the sovereigns most vulnerable to El Niño impacts. These nations face increased risk due to their reliance on debt, compounding the economic strain caused by severe weather. Across South America, severe floods and a lack of rain are disrupting farming operations.

The physical toll of the weather pattern is already visible across multiple regions. Southeast Asia is experiencing extreme air pollution driven by forest fires, while India recorded its weakest monsoon in more than a decade. Jonathan Dean, who leads BNP Paribas Asset Management’s natural capital strategy, is monitoring carbon-credit projects affected by the forest fires in Indonesia. The private equity strategy overseen by Dean has secured more than US$560 million in commitments from the International Finance Corporation and other development finance institutions.

Market participants are adjusting their strategies to navigate the volatility. Approaches include betting on interest rate changes driven by inflation, trading energy commodities, and investing in adaptation technologies such as smart irrigation and flood protection systems. Zulfiqar Ali, founder of ZAMS Asset Management, stated that winter is when climatic, geopolitical, and structural forces are likely to converge most intensely, signaling further turbulence ahead for global markets.
