Fitch warns El Niño could strain sovereign credit profiles

June 16, 2026 (MLN): Fitch Ratings has flagged heightened risks of economic disruption across multiple sovereigns as a newly formed El Niño weather phenomenon is projected to persist into early 2027, with lower-rated countries seen as most exposed to resulting fiscal, growth, inflation, and external liquidity pressures.

The US National Oceanic and Atmospheric Administration (NOAA) confirmed on June 11 that El Niño conditions had taken hold in the tropical Pacific, with forecasters assigning a 63% probability that sea surface temperatures could breach the threshold for a rare "very strong" El Niño.

The US Climate Prediction Center's projections from June 8 put the likelihood of the phenomenon continuing through the December 2026–February 2027 window at 96%.

Fitch said it was unlikely to link rating actions directly to El Niño unless its effects were clearly reflected in sovereign credit metrics.

However, the agency cautioned that environmental stresses stemming from the phenomenon could compound existing vulnerabilities, particularly for sovereigns in the 'B' category or below with limited market access or a history of rising debt during crisis periods.

El Niño typically brings drier-than-normal conditions to some regions while triggering heavier rainfall in others dynamics that can weigh on agricultural output and broader economic activity.

Fitch noted, however, that certain regions could benefit where elevated rainfall supports crop production.

The ratings agency also flagged a compounding risk on the food inflation front.

Global crop yields are already under pressure from elevated fertilizer prices linked to supply disruptions stemming from the US-Iran war.

Fitch warned that sustained shortages could amplify the upward pressure on globally traded food commodity prices that El Niño may trigger a risk it said could affect inflation prospects even in highly rated sovereigns.
