US diesel prices just hit the highest level in American history, which is bad news for consumers because higher trucking costs get passed on to everything you buy.

• Diesel is now more expensive than at any point ever, topping the previous records set in mid-2022 after Russia invaded Ukraine and in mid-2008.
• Even if you don't drive a diesel vehicle, this hits you: trucking and shipping companies pay more to move goods.
• Those companies pass the higher costs down the chain, so prices rise on everyday items like burgers and groceries.

Outlook: Expect higher prices across the board as transportation costs work their way into stores and restaurants.
