The article says El Niño-related rainfall contrasts and drought could affect Brazilian crops into the first half of 2027. In Paraná, excessive rain reduced winter-grain yields and quality; the state projects total winter-grain production at 2.84 million tonnes, down 28% from 2025, including wheat output of 1.9 million tonnes, down 34%.
Lower Paraná wheat and other winter-grain output can tighten domestic supply and support prices, while weather risks to other crops may add further uncertainty. Excess rainfall has also impaired quality, potentially limiting wheat’s suitability for milling and increasing feed-use availability of downgraded grain.
