In 2024, it would result as the 16th consecutive year for the demand of crude oil and petroleum products to be on a rise in India. The oil and gas sector is among the eight core industries in India and plays a major role in influencing the decision-making for all the other important sections of the economy. Thus, marginal changes in international trade or demand fro crude oil can have noticeable impacts on domestic diesel prices in Chennai as well.
Chennai is the largest city of Tamil Nadu with more residing population that any other city in India. As per the total passenger car sales made recently, most of the cars were bought by Chennai as the standard of living and earnings are quite high here than the neighbouring regions around. Two of the major car manufacturers in the country have notified that this year more than 90% of their top selling models were diesel engine cars, which indicates a strong potential for diesel prices in Chennai to have positive trend later.
In today's fast phased world with modern connectivity and strong trade dependencies, numerous aspects come into play while determining petrol rates in Tamil Nadu today and other parts of the country. Since the usage of diesel is mostly pushed towards transport vehicles and agricultural machineries in Tamil Nadu, the central and state government play major role to have stable petrol prices in Tamil Nadu today.

Indian government receives the highest contribution from fuel-tax from all corners of the country and revenue Generation is one of the significant reasons behind hike in diesel prices of Delhi today. If the government decides to increase the charges on the sector to infuse infrastructure investment, then a slight increase is evident in Delhi diesel rates today.
Apart from this, international aspects such as overall demand-supply scenario, trade agreements, geopolitical tensions, war escalations and regulations of crude oil exporting countries can contribute similarly to diesel prices locally. A disruption can cause the demand to increase, which would indirectly impact diesel rates in Delhi, while contradicting this, if recently there has been increase in supply by oil producing countries, a slight stability is also visible in diesel prices of Delhi today.
