Corn futures declined on Monday as traders positioned ahead of a USDA report expected to show US corn inventories swelled to the highest level since 1988. The prospect of ample supply, driven by favorable weather and large planted acreage, pressured prices. Market participants also weighed export demand concerns amid trade tensions.
