Background: India’s GDP Base Year Revision
- The Government announced revising the GDP base year from 2011–12 to 2022–23, with MoSPI aiming for release by February 2026 .
- A 26-member Advisory Committee on National Accounts Statistics (ACNAS), chaired by Biswanath Goldar—including RBI, central/state officials, academia—was formed to guide methodology and incorporate new data sources .
Why Transparency is Critical
- Restoring Credibility: The 2015 revision faced criticism for over-reliance on corporate MCA-21 data, potentially overstating growth and eroding trust .
- Global Standards Alignment: Frequent (every 5–10 years) base year updates align with UN/IMF recommendations, ensuring data comparability and reducing inflation biases .
- Enhanced Policymaking: A reliable base year reflects actual economic structure—services, digital platforms, informal sector—vital for informed decisions .
Expert Recommendations for a Robust Process
Based on recent expert insights:
- Methodological Clarity
- Publish a technical white paper detailing:
- Sector weight computation,
- Deflator usage (preferably double deflation),
- Back series methodology
- Address past corporate bias and data gaps transparently .
- Publish a technical white paper detailing:
- Independent Third‑Party Reviews
- Engage IMF, World Bank, academic peers for impartial assessments.
- Encourage academic and civil society oversight .
- Regular Scheduled Updates
- Institutionalize base-year revisions every 5 years per National Statistical Commission norms—not skip cycles (like 2017–18) .
- Hybrid Data Sources
- Combine corporate (MCA‑21) and survey-based data (e.g., ASI, PLFS, CES).
- Integrate administrative digital indicators (UPI, GST, EPFO) to capture informal economy growth .
- Institutional Accountability
- Empower NSC or MoSPI to own transparent communication.
- Create a dedicated portal with:
- Methodology,
- Data releases,
- Peer reviews to reinforce public trust .
Implications for Policy and Credibility
- Economic Decision‑making: A transparent, accurate GDP base aids in setting budgets, evaluating sectoral growth, and calibrating fiscal/monetary strategy.
- Investor Confidence: Reliable macro-data is key to attracting global investment and improving India’s economic ratings.
- International Comparability: Aligning with global norms supports India’s positioning in G20, IMF, and multilateral dialogues.
