Abstract

Movements in the Indian Rupee against the US Dollar have important implications for macroeconomic stability in India. Exchange rate depreciation affects inflation, trade balance, and overall economic performance. This study examines the key macroeconomic and global factors influencing the depreciation of the Indian Rupee against the US Dollar using quarterly time-series data from 2010Q1 to 2024Q4.

The study applies an Autoregressive Distributed Lag (ARDL) approach to analyse short-run and long-run relationships between the exchange rate and selected variables, including crude oil prices, inflation differential, interest rate differential, and the US Dollar Index. Stationarity of the variables is examined using the Augmented Dickey–Fuller test, and the ARDL bounds testing approach is used to assess the existence of long-run relationships.

The empirical results indicate that crude oil prices and global dollar strength have a statistically significant impact on the depreciation of the Indian Rupee in the short run. In contrast, inflation and interest rate differentials do not show significant effects. The bounds test does not provide strong evidence of long-run cointegration, suggesting that exchange rate movements are largely driven by short-term external shocks rather than stable long-run fundamentals. The findings highlight India’s vulnerability to global economic conditions and underline the importance of external sector management for maintaining macroeconomic stability.
