WHY IS THIS IN NEWS?
- IMF’s Article IV Consultation (2025) assessed India’s national accounts and gave a Grade ‘C’ for the quality of GDP data.
- Grade ‘C’ = “shortcomings that hamper surveillance” → second-lowest level.
- IMF highlighted:
- Periodic sizeable discrepancies between production and expenditure GDP estimates.
- Use of an outdated base year (2011–12).
- Over-reliance on Wholesale Price Index (WPI) for deflating nominal values.
- Need to expand expenditure-side data and informal sector coverage.
- Assessment is significant because India is expected to release Q2 FY2025–26 GDP numbers, and concerns affect global investor confidence.
Relevance
GS3 – Economy / Growth Measurement
• Quality of GDP estimation under MOSPI/NSO scrutiny.
• Discrepancies between production vs expenditure GDP.
• Outdated base year (2011–12) and need for rebasing.
• Deflator issues (WPI–CPI divergence).
• Statistical system reforms: MCA-21 data, GSTN integration.
GS2 – Governance / Institutions
• Role of IMF’s Article IV surveillance.
• Credibility of official statistics as a governance issue.
• Transparency norms and reforms in data architecture.
• Centre–State coordination for data collection (industries, services, informal sector).
• Strengthening statistical autonomy & capacity.
HOW GDP IS MEASURED ?
Three Approaches
- Production Approach (GVA method)
- Sum of value added by agriculture, industry, and services.
- Income Approach
- Sum of wages, profits, rents, and mixed income.
- Expenditure Approach
- GDP = C + I + G + (X – M).
- Should converge with production-side figures.
Ideal Condition
- All three approaches should produce near-identical results.
- Persistent divergence = data quality problem, structural inconsistencies.
WHAT EXACTLY IMF FLAGGED ?
A. “Sizeable Discrepancies” Between GDP Approaches
- Large, recurrent differences between:
- Production-side GDP (GVA-based)
- Expenditure-side GDP (C+I+G+X−M)
- Economists flagged this over the past 5 years:
- Private consumption growth often inconsistent with household survey indicators.
- Investment (GFCF) estimates occasionally contradict credit data & corporate filings.
- IMF classifies this as a methodological weakness affecting reliability.
B. Base Year Too Old (2011–12)
- Structural shifts in 13 years:
- Digitisation, GST rollout, UPI-led formalisation.
- E-commerce, gig economy, platform work.
- Deflation of manufacturing due to global price changes.
- Outdated base year → wrong weights → distorted GDP.
C. Over-Reliance on Wholesale Price Indices
- WPI used to deflate:
- Manufacturing GVA,
- Nominal capital formation,
- Some components of GFCF and inventories.
- Issues:
- WPI excludes services (57% of GDP).
- Highly sensitive to commodities, making real GDP volatile and inaccurate.
- CPI-based deflators are more reflective of consumer reality.
D. Limited Expenditure-Side Data
- India primarily uses Income Approach for GDP.
- Expenditure estimates (C, I, G, NX) rely on:
- Sparse household surveys,
- Small-sample enterprise surveys,
- Rough extrapolations.
- IMF wants expenditure-side to be strengthened and independently robust.
E. Informal Sector Under-Coverage
- Informal sector = ~45–50% of employment (varies by survey).
- GDP estimation largely model-based:
- Uses outdated NSS data.
- Limited real-time surveys post-2011–12.
- IMF says this reduces reliability and timeliness.
IMF’s GRADING SYSTEM
| Grade | Meaning |
| A | High-quality data; internationally comparable |
| B | Broadly adequate; minor weaknesses |
| C | Shortcomings hamper surveillance (India gets this for National Accounts) |
| D | Severe deficiencies |
India’s Overall Score
- Overall: Grade B (across all data categories)
- National Accounts: Grade C → primary area of weakness.
IMPLICATIONS OF THE ‘C’ GRADE
A. Policy-Making Impact
- If GDP reliability is weak:
- Monetary policy signals (RBI) become less precise.
- Fiscal policy targeting becomes less credible.
B. Investor Confidence
- Foreign investors use GDP data for:
- Valuation of Indian markets,
- Assessment of macro stability,
- Pre-investment risk modelling.
- ‘C’ grade may raise caution, particularly among sovereign funds.
C. International Comparability Issues
- Difficulty comparing India with:
- OECD economies,
- Asian peers (Indonesia, Vietnam, Philippines),
- China (despite opacity).
D. Domestic Credibility
- Economists have long critiqued:
- Back-series revisions,
- Post-2017 manufacturing volatility,
- Divergence between GDP and ground-level indicators (PLFS, ASI, credit data).
GOVERNMENT’S POSITION
- India argues:
- GVA-based method is robust and widely used.
- Discrepancies normal in developing economies with large informal sectors.
- Revised base year planned after new household surveys (2022–23, 2023–24).
- Transition to supply-use tables (SUTs) is ongoing.
STRUCTURAL CAUSES OF GDP DISCREPANCIES
A. Informal Sector Dominance
- Difficult to track productivity and incomes in real time.
B. Data Gaps
- Large gaps in:
- Household consumption,
- Unincorporated enterprises,
- Self-employment earnings,
- Small manufacturing units.
C. Outdated Surveys
- Key datasets:
- NSS 2011–12 consumption survey,
- Unincorporated enterprise surveys,
- ASI and IIP with limited representativeness.
D. Weak Price Deflation Mechanism
- Correct deflation = accurate real GDP.
- WPI-based deflation induces errors.
REFORMS IMF EXPECTS
- Update base year to 2017–18 or 2020–21 (debate ongoing).
- Increase frequency of:
- Household consumption surveys,
- Enterprise surveys,
- Service sector surveys.
- Expand use of:
- GST data,
- Corporate filings (MCA-21),
- Digital payments data.
- Strengthen expenditure-side GDP with more granular monthly/quarterly data.
