14 Nov 2025 : Urgent update

 Editorial 1 : ​​​Urgent update

Context

India must urgently overhaul its Consumer Price Index.

 

Introduction

Retail inflation data for October highlights how urgently India needs an updated Consumer Price Index (CPI)framework. Although headline inflation appears to have dropped sharply, this decline is largely a statistical distortioncreated by base effects rather than an actual easing of prices. The mismatch between the CPI’s reported figures and people’s real-world experiences raises serious concerns about the index’s reliability and relevance.

 

Inflation Drop: More Statistical Illusion Than Reality

  • October retail inflation fell to 0.25%, the lowest since 2012.
  • This sharp fall appears positive but is largely a statistical anomaly, not a real decline in prices.
  • The food and beverages category recorded a 3.7% drop, the steepest in the current CPI series.
  • The fall happened mainly because last year’s food inflation was extremely high (9.7%), creating a high base effect.
  • Despite CPI showing negative food inflation, market vegetable prices have actually risen recently.

 

How Food Weight Pulls Down Overall CPI

  • Food and beverages have a 46% weight in the CPI basket.
  • This heavy weight means the distorted food inflation reading dragged down the entire index.
  • Other major sub-groups — fuel and light, housing, tobacco, and miscellaneous — all recorded higher inflationthan last year.
  • Only clothing and footwear reflected a drop in inflation due to GST rate cuts.

 

Structural Problems in the Current CPI

  • The CPI still uses an outdated 2012 base year, making it poorly aligned with current consumption patterns.
  • Weightages no longer represent reality, often hiding trends rather than reflecting them.
  • A widening disconnect exists between CPI numbers and public experience — RBI’s September survey showed people perceived inflation at 7.4%, far higher than CPI estimates.

 

Policy Implications and Need for an Updated CPI

  • RBI’s Monetary Policy Committee relies on CPI for interest rate decisions.
  • The December meeting must interpret:
    • Growth data temporarily inflated by GST-related demand, and
    • Inflation numbers distorted by base effects and statistical noise.
  • These distortions complicate accurate monetary policymaking.
  • The Ministry of Statistics plans to release a new CPI series by the first quarter of the next financial year — an update that is urgently needed.

 

Conclusion

India’s current CPI framework, weakened by its outdated base year and misaligned weightages, no longer captures real inflation dynamics. As long as monetary policy relies on an index distorted by base effects, volatile food weights, and measurement gaps, policymaking will remain challenging. Updating the CPI is essential not only for statistical accuracy, but also for economic credibility, public trust, and sound policy decisions.
