Purchasing Power Parity (PPP)
Context: India is projected to become the world’s fourth-largest economy by 2025 in nominal GDP terms, but when adjusted for Purchasing Power Parity (PPP), it has already been the third-largest since 2009—though this does not necessarily reflect higher living standards or equitable development.
Important Pointers:
Definition: PPP refers to the equality of purchasing capacity between two currencies based on a common basket of goods.
Purpose: It allows for more accurate cross-country comparisons of economic productivity and living standards.
Exchange Rate Basis: PPP sets exchange rates based on the relative cost of a fixed basket of goods in different countries.
Market Exchange Rate vs PPP: Market rates are volatile and influenced by financial flows; PPP accounts for local price levels.
India’s GDP by Market Rates: According to IMF 2025 projections, India will be the 4th largest economy by market exchange rates.
India’s GDP by PPP: India has been the 3rd largest economy by PPP since 2009 and continues to hold that position.
Volatility Concern: Market exchange rates fluctuate and don't reflect domestic price levels, making them unsuitable for GDP comparison over time.
Impact on Poorer Countries: PPP inflates GDP figures more for countries with lower wages and prices like India.
Political Use: Governments may prefer market-rate rankings for political gain, despite PPP providing more realistic comparisons.
Per Capita GDP Reality: India’s per capita GDP was $2,711 (2024), ranking 144th by market exchange rates and 127th by PPP.
Big Economy Illusion: Large total GDP doesn't mean high well-being; per capita income and social indicators offer a truer picture.
PPP Limitations: Though useful, PPP can mislead if used without considering inequalities, informal sectors, or unpaid labour.
