At first glance, this appears to be a setback, especially when expectations were building around India overtaking more advanced economies.

Global GDP rankings are typically calculated using nominal GDP, which measures the total value of goods and services produced within a country at current prices and converts it into US dollars.

This conversion introduces a crucial variable, the exchange rate. Over the past year, the Indian rupee has depreciated significantly against the US dollar. As a result, even though India’s economy has grown in real terms, its value appears smaller when expressed in dollars.
