Editorial 1: The Curious Case of GDP Data
Context:
India’s GDP growth in real GDP (which adjusts for inflation) has consistently outpaced expectations. Policymakers have pointed to these high growth rates as evidence of India’s economic resilience, even amid global slowdown concerns. However, a closer examination reveals several anomalies that make India’s GDP story rather puzzling.
Real and Nominal GDP:
- Gross Domestic Product (GDP) can be measured in two ways:
- Nominal GDP is the total value of goods and services produced, calculated at current market prices.
- Real GDP adjusts nominal GDP for inflation, reflecting growth in actual output.
- Normally, the difference between the two depends on the rate of inflation.
- If inflation is high, nominal GDP should grow faster than real GDP. Conversely, if inflation is very low, real GDP growth can sometimes appear stronger.
- But in India’s recent case, real GDP growth has been running significantly ahead of nominal GDP growth.
- For example, data from Q1 of 2025 shows that nominal GDP grew only modestly, while real GDP registered strong expansion.
- This mismatch raises concerns about how inflation is being measured and deflated.
The Role of the GDP Deflator:
- The key factor in this anomaly is the GDP deflator, a measure used to adjust nominal GDP to real terms.
- Unlike CPI (Consumer Price Index) or WPI (Wholesale Price Index), the deflator is a broad-based index of price changes in the entire economy.
- If the GDP deflator is very low, or even negative, it implies that inflation is negligible or prices are falling.
- This mathematically boosts real GDP growth, even if nominal GDP is not very strong. In recent quarters, India’s GDP deflator has been unusually low, driven by:
- Falling commodity prices (especially crude oil);
- Weak wholesale inflation, which pulled down overall price growth;
- Discrepancies between CPI, WPI, and the deflator.
- As a result, India has been reporting high real GDP growth numbers even though household consumption, tax collections, and corporate earnings suggest sluggishness.
Discrepancies in GDP data:
- While the headline GDP growth suggests robust expansion, several ground-level indicators point otherwise:
- Sluggish private consumption: Household spending has not kept pace with claimed growth.
- Muted investment demand: Corporate balance sheets remain stressed, and new investment activity is limited.
- Tax revenue shortfalls: Both GST and direct tax collections have underperformed, inconsistent with strong GDP growth.
- Industrial production and exports: These have shown only modest improvements.
- This disconnect has made many economists skeptical. If the economy is truly growing as fast as real GDP suggests, then businesses, jobs, and tax revenues should show similar momentum.
Implications for Policy making due to anomalies in GDP data:
- The anomaly matters because policymakers rely heavily on GDP data to guide decisions on fiscal spending, interest rates, and reforms. Overstated real GDP growth:
- It may create complacency in government policy, reducing urgency for reforms.
- It can lead to mismatches in welfare spending and tax targets.
- It risks misleading foreign investors who depend on headline growth numbers to assess opportunities.
- It is a mismatch between perception and reality can ultimately hurt credibility of India’s economic statistics.
Conflicting views among Economists:
- Some analysts argue that the Indian economy may genuinely be undergoing structural shifts, which traditional indicators fail to capture.
- For instance, rising digitization, new-age services, and informal-to-formal sector transitions may not show up in older measures like IIP or tax data.
- Thus, part of the high real GDP growth might reflect under-documented improvements.
- Still, the unusually low deflator remains the central issue. Unless price measurement improves, the reliability of real GDP will continue to be questioned.
Way Forward:
India’s GDP story is thus a paradox as real GDP growth looks spectacular, while nominal GDP and on-ground indicators look subdued. The divergence is explained mainly by the GDP deflator, which has been unusually soft. Policymakers need to address concerns around data quality, transparency of deflators, and alignment with real-world economic indicators.
