Transport has already turned, a year ahead
The SDES monthly business survey in road freight publishes hauliers' opinion balance on the demand addressed to them. In June 2026 that balance stands at -26.4. In June 2025 it stood at -2.1. Twenty-four points and three tenths lost in twelve months, on a series that was still close to balance a year ago. Activity prospects follow, at -26.3 against -17.7 a year earlier. A third series from the same survey says where the pressure comes from: the price balance moves from +2.3 to +11.8. Hauliers raising prices while their demand collapses are not passing on market tension, they are passing on a bill. The diesel bill, whose INSEE consumer price index is up 37.1% year on year in August 2026. Crude explains only part of that rise, since Brent gains just 32.8% between the same two Augusts; the rest comes from refining, where quoted distillate almost doubles, at +98.3%. Diesel no longer tracks the barrel, it tracks the scarcity of what is drawn from it. The freight price index published by SDES confirms the rise is endured, not chosen: in the first quarter of 2026, road is the only mode whose prices are accelerating, at +2.4% year on year after +0.2% in late 2024, while sea freight drops from +24.4% to -14.3%, air from +12.2% to -1.8% and rail from +3.8% to -0.2%. Where the price is set on a world market, it collapses; where it has to cover a tankful, it rises. The outcome is on the court register: with 3,244 failures over twelve months to end-June, transport and warehousing sit 70.6% above their 2010-2019 average, far ahead of every other sector.
🔍 Focus: why the truck is decided before the round
A heavy truck is written off over five to seven years. A haulier who doubts 2027 does not start by cutting rounds, he postpones his fleet renewal: the decision costs nothing and can be undone. Vehicle orders therefore move before activity does, which is what makes them a leading indicator rather than a thermometer. Over the first eight months of 2026, France registered 28,313 new heavy trucks, 3.0% fewer than in 2025 and 29.3% fewer than in 2019, and 229,951 light commercial vehicles, down 4.9% year on year. The counter-test sits in the same SDES file: registrations of passenger cars, which mix households and company fleets, are up 2.9% instead. The vehicle used to produce is falling, the one used to travel is rising. That is the signature of a company's doubt, not a consumer's.
- Demand addressed to road freight loses 24.3 points in a year: a balance of -26.4 in June 2026 against -2.1 in June 2025.
- Failures in transport and warehousing stand 70.6% above their 2010-2019 average, first of the twelve sectors INSEE tracks.
- Road is the only freight mode whose prices are accelerating, at +2.4% year on year in the first quarter of 2026, while sea freight falls 14.3%.
- The signal to watch: diesel. As long as its price stays 37% above a year ago, a haulier's margin is decided in the indexation clause, not in the volume.
