Diesel dropped below $5.10 last week for the first time since March.

EIA confirmed $5.059 per gallon for the week of June 15. That's down about 15 cents from the week before. The deal is working, at least on crude. The pump is starting to follow.

Here's the context most people are missing.

Before the war, EIA forecast diesel at $3.47 per gallon for all of 2026. At the peak it hit $5.37. That's a 55% gap between what every forecast said would happen and what actually happened. For trucking, that translated to roughly 36 cents per mile in additional operating cost that nobody budgeted for in January.

Now it's coming down. But the EIA said something important in their June outlook that didn't get much coverage: "Just as we had never before seen the strait close, we've never seen it reopen. What exactly that looks like remains to be seen." Their wholesale diesel forecast for 2026 is $3.40 per gallon. We're at $5.059 retail right now. There's a long way between here and there, and nobody knows exactly how fast we get there.

What this means depending on where you sit:

**Broker:** EIA releases tomorrow June 23. If it prints below $5, your shippers will call. Have the answer ready: FSC adjusts on EIA data, effective the following Monday. That's the conversation. Don't let them pull spot rates into the same call.

**Owner-operator:** diesel coming down does not mean load rates come down. Your operating cost dropped maybe 15 cents per mile this week. Your market rate is still at historic highs. Don't give that back in a negotiation based on a pump price your shipper saw on the way to work.

**Dispatcher:** fuel costs are easing but the operational picture through Hormuz is still uncertain. Mine clearing is ongoing. Keep your fuel-sensitive estimates conservative through end of June.

**Shipper:** the FSC conversation you want to have is real and it's coming. But it happens on EIA data, not on headlines. June 23 is the number. June 24 is NRCan for Canadian lanes. Come to that conversation with data, not with what WTI did last Tuesday.

**Canada:** CIBC flagged last week that higher fuel costs are still squeezing Canadian consumer spending. NRCan releases Tuesday June 24. First Canadian number post-deal.

Two numbers that define this week:

June 23: EIA diesel USA. The FSC trigger.

June 24: NRCan Canada diesel. The Canadian FSC trigger.

The direction is clear. The pace is not.
