Fuel and Power WPI Inflation at 20.05%: Energy-Cost Pass-Through and Margin Stress Test
By Ravi Sisodia · Reviewed by CA Divyanshu Sengar · Updated 5 October 2026
2-minute summary
- Fuel and Power WPI inflation was 20.05% in July 2026, lower than 27.41% in June, while the group index fell to 105.4 from 111.1.
- Energy procurement needs its own sensitivity table because fuel-and-power inflation can remain elevated even when the group index falls sharply month to month.
- Use the August release to confirm the July comparator, but do not relabel the 20.05% July figure as a current August energy reading.
Current position
For July fuel and power, the useful signal is the combination of a high year-on-year rate and a lower group index than June. That combination points to base effects and recent price direction that should be separated in management commentary.
Control and evidence map
| # | Control / evidence requirement | |
|---|---|---|
| 1 | The combination of high year-on-year inflation with a month-on-month index decline shows why finance teams should track level, annual rate and recent direction separately. | |
| 2 | Match coal, gas, electricity and petroleum exposure to actual contracts. | |
| 3 | Create a pass-through matrix showing which customers absorb energy escalation and with what lag. | |
| 4 | Reconcile fuel surcharges in freight contracts rather than folding them into factory power cost. | |
| 5 | Stress-test EBITDA using invoice-level energy assumptions, not the broad index alone. | |
Worked example
A ceramics manufacturer can build an energy bridge using electricity, gas and freight contracts instead of assuming a 20.05% increase in every utility invoice.
Common mistakes
- Do not confuse a lower inflation rate with lower prices versus last year.
- Use actual tariff/fuel formulas where contracts exist.
- Separate direct energy from freight and supplier pass-through.
Frequently asked questions
Did energy prices fall 20.05%?
No. 20.05% is the year-on-year inflation rate for the group.
Why did the index fall while inflation stayed high?
Annual comparison and month-to-month direction measure different things.
Should every customer receive the same surcharge?
No; contract rights and product economics differ.
What is the best finance control?
An energy bridge tied to actual tariffs, fuel formulas and pass-through lags.
