Surging Diesel and Freight Costs Drive October Grocery Price Spike Amid Iran War

Grocery prices rose across nearly every aisle in October, led by fresh food, as upstream energy and transportation costs surged.
According to the post, the increases are being driven by supply-chain shocks rather than monetary policy:
- Diesel prices have climbed more than 60% since the Iran war began.
- Truck freight costs are up over 17%, passing higher energy expenses through agriculture, shipping, and retail stocking.
The author characterizes the move as a temporary price shock rather than broad inflation, noting that elevated food costs should ease once crude oil supply normalizes.
