The rate of diesel in Tamil Nadu

A rise in the price of diesel means that you will shell out more on commuting. Since the majority of commercial vehicles run on diesel, a rise in price for this fuel will have an impact on the cost of transportation. This, in turn, can put upward pressure on the commodity prices, and taken together, can lead to an increase in the rate of inflation. In order to mitigate these inflationary pressures, the Reserve Bank of India (RBI) increases interest rates. This translates to higher cost of borrowing. Thus, a rise in diesel prices can have a cascading effect on the economy.
Diesel prices are governed by a host of factors, primary amongst them are the price of Brent crude and government levies. For instance, a rise in the price of Brent crude oil can lead to an increase in the price of domestic diesel.

How are diesel prices calculated in Tamil Nadu?

Diesel prices in Tamil Nadu are calculated by taking into account the price of Indian crude oil basket, dealer and refining margins, transportation costs, state value added tax and central excise duty. It is pertinent to note that state levy varies across states. This explains why diesel prices differ across states. Changes in central excise duties also affect diesel prices significantly. A cut in central excise duty helps in cooling off of elevated diesel prices. Besides, gyrations in the price of Brent crude oil can also affect the domestic price of diesel.
