Meteorologists warn that a developing El Niño event could become one of the most intense recorded in several decades [1].

This climate shift matters because it drastically alters rainfall patterns worldwide, posing a direct threat to global food security and crop yields. In Brazil, the phenomenon is expected to impact key agricultural regions, potentially driving up inflation as production costs rise.

The Australian Bureau of Meteorology said the event could be the most intense in seven decades [1]. Other meteorologists have provided a wider range of historical context, suggesting the event could be the strongest since 1950 [2] or even the worst in 140 years [3].

This natural climate cycle is expected to intensify during the second half of 2026 [4]. While El Niño is a recurring cycle, experts note that its combination with ongoing climate change can amplify its effects, leading to more severe droughts or floods.

In Brazil, the economic stakes are high. An analyst from the Copom said El Niño has officially entered the radar as a high risk for inflation [5]. The shift in weather patterns often disrupts the production of staples such as soy, and coffee, which are critical to the Brazilian economy.

Agricultural specialists note that while the alarm regarding a "super El Niño" is significant, the actual damage to the agro-sector depends on the precise timing and intensity of the rainfall shifts [6]. The Tropical Pacific Ocean remains the center of the phenomenon, where warming sea surface temperatures trigger the atmospheric changes felt globally.

Government agencies and farmers are now monitoring the Pacific to prepare for the volatility expected in the coming months [4].

“El Niño could be the most intense in seven decades.”

The convergence of a high-intensity El Niño with existing global warming creates a multiplier effect on weather extremes. For global markets, this means increased volatility in commodity pricing, as major agricultural exporters like Brazil face unpredictable harvests. The wide variance in meteorological projections—ranging from a 70-year to a 140-year peak—underscores the uncertainty and the high potential for systemic economic shocks in the latter half of 2026.
