At the NITI Aayog meeting on June 11, 2026, Tamil Nadu Chief Minister C. Joseph Vijay announced the goal of transforming Tamil Nadu into a $1.5 trillion economy by 2035-36. A similar view has also been expressed by others.

Tamil Nadu’s Gross State Domestic Product (GSDP) was ₹35.29 lakh crore in 2025-26. To achieve the target of $1.5 trillion in 10 years, Tamil Nadu would have to increase the size of its economy to ₹172.56 lakh crore by 2035-36, registering a 4.9-fold increase. This calculation is based on the assumption that the exchange rate of one dollar in terms of rupees will appreciate by 2% per annum from its present level, touching ₹115.38 per dollar in 2035-36. This implies that achieving the target would require a nominal growth rate of 17.2% and, assuming inflation of 5%, a real growth rate of 12.2% per annum continuously for 10 years.
