# U.S. grains: Corn, soy drop; soyoil limit-down - Grainews

> U.S. corn and soybean futures eased and soyoil futures fell by their daily limit on June 11, 2021, after reports that the EPA was considering relief from biofuel blending mandates for oil refiners. Rain forecasts for the U.S. Midwest and northern Plains added pressure, and palm oil dropped 4-5% overnight. Soybeans posted their sharpest weekly drop since January.

## Why it matters

Expected weaker biofuel feedstock demand from possible mandate relief pulls soyoil and soybean prices lower. Palm oil weakness reinforces the downside across vegetable oils.
