This research article examines the difference between tradable and non-tradable sectors and their insinuations for economic variables for example relative prices, nominal and real exchange rates. The study delivers an inclusive analysis of price indices employed to measure tradable and non-tradable goods, drawing on earlier studies. It investigates four indices for tradable goods: the wholesale price index (WPI), consumer price index (CPI) for main trading partners, export price index (EPI), and import price index (IPI). On the other hand, for non-tradable goods sector, the domestic CPI and GDP deflator are examined. These indices are employed to gauge the real exchange rate, a crucial variable for measuring a country's price competitiveness.
