Diesel pass-through lag
What it is
Fuel is typically 30-40% of a road transporter's operating cost, and contracts pass diesel price changes through with a lag of a quarter or by formula
Spot and small-operator freight has no formal mechanism at all
Impact on industries
- The lag means margin compresses whenever diesel rises quickly, and the transporter funds the gap until the reset
- Small operators without contracts absorb the full move immediately, which is why fuel spikes drive informal capacity out of the market
- The mechanism reverses when diesel falls, so the transporter retains the benefit until the next reset
- Administered retail fuel pricing means diesel does not always follow crude, so the exposure is to policy as much as to commodity markets
