# Corn Futures Slide as Oil Selloff Triggers Profit-Taking

> Chicago corn futures closed lower Monday, with the December contract down 13.5 cents to $4.47 per bushel. The decline followed a sharp drop in crude oil after the US suspended airstrikes on Iran, which raised hopes for diplomacy and eased Strait of Hormuz shipping concerns.

## Why it matters

Roughly 40% of US corn goes to ethanol, so lower crude reduces the biofuel incentive for corn use and weighs on prices. Easing Iran tensions could keep energy and grain prices under pressure.
