MoSPI organized Third Pre-release Consultative Workshop on the Base Revision of GDP, IIP and CPI on 30th January 2026 at Chennai

1. At a Glance

• MoSPI organised the third Pre-release Consultative Workshop on the Base Revision of GDP, IIP, and CPI at Chennai on 30 January 2026 [1][2].
• Part of a stakeholder-consultation series preparing for India's biggest macro-data overhaul of the decade: shifting base years of three flagship indicators [1][3].
• Examinable for UPSC — touches national income accounting, statistical system reforms, NSC, and CPI/IIP methodology.

2. Why in the News

• Workshop concluded the three-city pre-release consultation cycle ahead of release of new GDP series on 27 Feb 2026, new CPI series on 12 Feb 2026 and new IIP series in May 2026 [3].
• Marks transition of GDP/IIP base from 2011-12 → 2022-23 and CPI base from 2012 → 2024 [3].

3. Background & Evolution

• Base year revision is a periodic exercise to keep macro indicators aligned with the current structure of the economy; the prior GDP base (2011-12) had run for over a decade [3].
• First workshop: 26 November 2025 at Mumbai; Second workshop: 23 December 2025 at Bharat Mandapam, New Delhi; Third: 30 January 2026 at Chennai [1][2].
• Revision guided by Advisory Committee on National Accounts Statistics (ACNAS) — a standing committee advising MoSPI on data sources & methodology for NAS [2].
• New surveys feeding the revision: PLFS (Periodic Labour Force Survey), HCES (Household Consumption Expenditure Survey), ASUSE (Annual Survey of Unincorporated Sector Enterprises) [3].

4. Core Static Facts

• Organising Ministry: Ministry of Statistics and Programme Implementation (MoSPI) [1].
• Venue/Date: Chennai, 30 January 2026 [1].
• Key dignitaries:
• Dr. C. Rangarajan — Chairman, Madras School of Economics; former Chairman, EAC-PM; ex-Governor, RBI [1].
• Prof. Rajeeva Laxman Karandikar — Chairman, National Statistical Commission (NSC) [2].

• Dr. Saurabh Garg — Secretary, MoSPI [2].

• Participants: ~150 — economists, RBI, Barclays, Goldman Sachs, academia, C.R. Rao AIMSCS [2].

• New base years: GDP & IIP → 2022-23; CPI → 2024 [3].
• Release dates: CPI new series – 12 Feb 2026; GDP new series – 27 Feb 2026; IIP new series – May 2026 [3].
• Guiding committee: ACNAS for NAS; separate Technical Advisory Committees (TACs) with experts from academia, Centre, States, RBI for CPI/IIP [3].

5. Multi-Dimensional Analysis

Economic

• Updated weights will recalibrate GDP composition (services share, digital economy, gig sector) and recompute growth/inflation trajectories [3].
• New CPI basket from HCES 2022-24 will alter weight of food vs. services — directly affecting RBI's 4% (±2%) inflation target under flexible inflation targeting [3].

Administrative / Statistical Governance

• Demonstrates institutionalised pre-release consultation — MoSPI engaging users before data release rather than after, strengthening credibility [1].
• Use of PLFS, HCES, ASUSE data marks shift toward survey-driven, less proxy-dependent estimation [3].

Ethical / Governance

• Rangarajan's emphasis: "Reliable and transparent data is key to sound policy-making" — addresses long-standing critique of India's statistical credibility [1].
• Brings non-government users (foreign banks, rating agencies) into pre-release dialogue — a transparency-and-trust measure [2].

Federal

• Workshops rotated Mumbai → Delhi → Chennai to capture regional/state-level stakeholder feedback, relevant since State DESs feed into NAS compilation [1][2].

Plausible question stems

1. "A robust statistical system is the foundation of evidence-based policymaking." In light of the recent base year revision of GDP, IIP and CPI, examine MoSPI's reform initiatives. (15 marks)
2. Discuss the significance of updating the base year of macroeconomic indicators. What methodological improvements have been incorporated in India's 2022-23/2024 base revision? (10 marks)
3. How will the revision of the CPI basket affect the conduct of monetary policy under India's flexible inflation targeting framework? (10 marks)

9. Related Topics to Study Next

• National Statistical Commission (NSC) — Rangarajan Commission recommendation; oversees statistical system.
• PLFS / HCES / ASUSE — input surveys; standalone Prelims hooks.
• Flexible Inflation Targeting & MPC — CPI base change directly impacts.
• SNA 2008 / SNA 2025 — international System of National Accounts framework MoSPI aligns with.
• GVA vs GDP, deflators, chain-linking — methodology basics.
• IIP — eight core industries, weights — closely linked indicator.
• Economic Advisory Council to PM (EAC-PM) — Rangarajan link.
• Periodic Labour Force Survey & unemployment debate — uses same MoSPI survey infrastructure.

10. Common Errors / Trap Areas

• Wrong base year: GDP/IIP move to 2022-23, not 2023-24; CPI moves to 2024, not 2022-23 [3].
• Wrong ministry: It is MoSPI, not NITI Aayog or Ministry of Finance, that revises base years [1].
• NSC ≠ ACNAS: NSC (Karandikar) is the apex statistical advisory body; ACNAS is the specific committee for National Accounts methodology [2].
• Mixing up workshop venues: Mumbai (1st) → Delhi (2nd) → Chennai (3rd); not the reverse [1].
• Rangarajan is currently Chairman of Madras School of Economics, not RBI or EAC-PM (those are former positions) [1].
