Inflation Lessons – RBI needs to improve accuracy in its predictions

Context:
India’s retail inflation for September 2025 stood at 1.54%, the lowest in 99 months, signalling a phase of disinflation with significant implications for the Reserve Bank of India’s (RBI) monetary policy strategy and forecasting accuracy.

Key Highlights / Details:

  • Trend in Inflation:
    • Average retail inflation for the first half of FY2025–26 is 2.2%, just within the RBI’s comfort band of 2–6%.
    • Except for August, inflation has been declining consistently each month in the current fiscal year.
  • Sectoral Insights:
    • The clothing and footwear category reported 2.3% inflation in September 2025, reflecting oversupply and weak demand.
    • Inflation has remained subdued across multiple sectors for nearly two years.
  • Demand and Policy Measures:
    • The government has attempted to boost demand through income-tax rebates and GST rate reductions.
    • However, consumers are focusing on saving and debt reduction rather than increasing consumption.
  • Monetary Policy Implications:
    • With inflation persistently below the 4% target, there is an argument for the RBI to reassess its inflation projection methodology.
    • The central bank may need to adjust policy rates more dynamically to support growth while maintaining price stability.
  • Forecasting Challenges:
    • In April 2025, RBI had projected annual inflation at 4%, later revising it down to 2.6% — a sharp divergence suggesting forecasting inaccuracies.
    • A more data-driven and adaptive model is needed to capture shifts in consumption and global demand patterns.

Relevant Prelims Points:

  • Inflation Targeting in India: Adopted under the Monetary Policy Framework Agreement (2016); target = 4% ± 2%.
  • CPI (Consumer Price Index): Main measure for retail inflation in India, compiled by NSO, MoSPI.
  • RBI’s Monetary Policy Tools: Repo rate, reverse repo, CRR, SLR, and Open Market Operations (OMOs).

Relevant Mains Points:

  • Economic Stability: Importance of accurate inflation forecasting in ensuring monetary policy credibility.
  • Policy Transmission: Role of rate cuts and fiscal stimulus in boosting private consumption.
  • Macroeconomic Coordination: Balancing low inflation with sustainable growth in a post-pandemic, low-demand economy.
