> Rosario cut its 2026/27 Argentine soybean harvest estimate by 200,000 tons to 47.8 million tons, citing weaker margins versus corn. It raised its corn forecast to 67.5-70.5 million tons and its wheat estimate by 2.4% to 21 million tons.

## Why it matters

A smaller soybean crop with acreage shifting to corn tightens soymeal and soyoil export supply while adding corn availability. The net effect is mildly supportive for soy products and bearish for corn.
