## Diesel hits record high
Diesel reached $6.40 per gallon this morning, up 73 percent from a year ago. The price surge affects far more than just truck drivers.
## Why diesel affects everything
Semis, tractors, excavators, freight trains, cargo ships, and garbage trucks all run on diesel. That means diesel costs touch virtually every part of the economy.
## What caused the spike
The US war with Iran started the rise. Then an attack on Saudi Arabia's pipeline and Ukrainian drone strikes on Russian refineries made things worse.
## Trump's response so far
President Trump asked Ukraine to stop targeting refineries and relaxed labor rules for fuel truck drivers. He's considering invoking the Defense Production Act.

> Not on the solution list, notably: winding down the war in Iran, which kickstarted this whole thing.
## The hidden cost to households
Brown University researchers estimate the extra diesel costs since the Iran War began work out to roughly $374 per US household.
## Why businesses can't cut back
Diesel demand is inelastic. A farmer halfway through harvest can't just stop running a combine because fuel gets expensive.
## Where you'll feel it first
Expect higher grocery bills, especially on perishable products that travel long distances. Milk, meat, fruits, and vegetables will cost more.
## Key takeaway

Diesel price spikes affect nearly every product you buy because trucks, trains, and farm equipment can't easily cut back on fuel use.
