India's PPI reform half-made

India's new price index faces gaps despite 50-year delay from WPI.

In brief

India's new price index faces gaps despite 50-year delay from WPI. India's producer price index (PPI) has gaps in collection, trial status, and services coverage that may take five years to fix. Originally reported by Financialexpress.

India replaces WPI with PPI

India published its first producer price index (PPI) and began retiring the wholesale price index (WPI) it has relied on since 1942.

50-year delay

India's WPI was first published on January 10, 1942, and the Office of the Economic Adviser has since found registers suggesting compilation as early as 1915.

PPI vs WPI

PPI vs WPI

A PPI measures what a producer actually receives at the factory gate, net of taxes and trade margins, and covers services which the WPI does not.

Collection gaps

The government has not explained how it secured cooperation from Indian companies despite GST e-invoicing providing transaction-level B2B records.

Trial index status

India's input PPI (IPPI) is labeled a 'trial index' with no criteria for graduation or date by which it is expected to become a full index.

Services coverage

The new services PPI covers only seven sub-sectors: banking, securities transactions, insurance, pension fund management, railways, air passenger transport, and telecom.

Five-year deadline

With the WPI due to be discontinued in five years, gaps in the PPI must be closed within five years or contracts will rely on an incomplete index.

Why it matters

The WPI remains the reference point for indexation, cost escalation, and contract pricing across industry, determining cash flows and tariff revisions.

What happens next

India must close gaps in PPI collection, trial status, and services coverage within five years to avoid contract issues.

Here's the gist

India's producer price index (PPI) has gaps in collection, trial status, and services coverage that may take five years to fix.
