# Market Talk | Volatility Returns As Energy Markets Grapple With Strait Of Hormuz Shutdown

> Energy markets rebounded as the Strait of Hormuz remained effectively shut despite optimism about a ceasefire. ULSD futures rose about 20 cents/gallon after a record-scale drop the previous day, and Iranian drones struck a Saudi East/West pipeline. US crude inventories rose for a seventh straight week while the SPR declined slightly.

## Why it matters

Continued strait closure and the attack on Saudi pipeline capacity keep crude and diesel supply tight, supporting energy costs for feed milling and transport. High volatility suggests elevated price risk for buyers.
