# Market Talk | Volatility Returns As Diesel Surges And Global Supply Chains Tighten

> Diesel futures surged on September 30, with November ULSD up more than 21 cents on the day and the expiring October contract back above $5/gal. Three tankers were reportedly attacked near the Strait of Hormuz, and crude rose more than $1/bbl. Analysts said oil flows were nearing pre-war levels, but diesel supply was still tight.

## Why it matters

Renewed attacks in Hormuz raise the risk of renewed supply loss and higher fuel costs for feed logistics. The diesel tightness suggests fuel prices could stay elevated even if crude eases.
