# Heat wave hits Argentina, threatening corn and soybean crops

> A heat wave pushed temperatures near 40°C in Argentina while key agricultural regions need 70-80 mm of rain, with no significant relief expected until February. Forecasters expect corn yield cuts, with early-planted corn hit hardest, and sorghum yields reported at 2.5 t/ha versus 7 expected. Some areas received 60-70 mm of rain over the weekend.

## Why it matters

Expected corn and sorghum yield losses from Argentina, the third-largest corn supplier, tighten export supplies and support feed grain prices, while pasture losses could boost feed demand for livestock.
