# Closure of the Strait of Hormuz causes urea, diesel prices to spike as planting season begins in Arkansas

> Shipping through the Strait of Hormuz has stalled due to the conflict, with more than 200 vessels stranded and insurers cancelling cover for Persian Gulf shippers. Arkansas urea dealer quotes rose from the upper $500s to as high as $700 per ton, and diesel prices also spiked as spring planting began.

## Why it matters

Higher urea and diesel costs raise the cost of growing feed grains and transporting feed, while the closure of a key chokepoint lifts crude and freight costs across the feed chain.
