Tamil Nadu Chief Minister C Joseph Vijay is run the state more like a CEO than a career politician. A new Niti Aayog report card reflects that approach. The report has drawn applause and a to-do list for Tamil Nadu and its new Vijay-led TVK government.
Tamil Nadu has been ranked as the third most investment-friendly state by Niti Aayog in its first Investment Friendliness Index 2026 report.
Behind the praise, however, are some reminders about aging airport infrastructure, gaps in wastewater management and other issues that continue to test Tamil Nadu’s investment ambitions. The question now is whether Chief Minister Vijay will turn these identified weaknesses into his next governance mission.
NITI Aayog’s Investment Friendliness Index 2026 report was released on July 18. The report cited Tamil Nadu’s strong performance as a result of its infrastructure, institutional capacity and political stability. Tamil Nadu ranked first among large states in infrastructure, backed by the country’s most efficient industrial corridors, better road connectivity linking Chennai, Coimbatore and Hosur, a broader railway network serving the automobile, textile and cement industries, and ports ranked first in terms of response time.
The state’s power sector also emerged as a key strength, posting power outages and transmission losses below average for large states, while drawing significant support from its growing wind and solar energy capacity.
But despite these criteria that have made Tamil Nadu an investment-friendly state, the report makes it clear that Tamil Nadu’s journey to becoming India’s most investment-friendly state is not an unfinished work.
Several indicators for Tamil Nadu continue to lag behind the country’s best-performing states, with deficiencies in areas such as airport infrastructure, wastewater management and other civic and logistical bottlenecks emerging as the next set of governance challenges. It is these gaps that now present CM Vijay with the opportunity to go beyond maintaining Tamil Nadu’s position and take the state to the top of the national rankings.
HOW TAMIL NADU CAN BECOME THE BEST STATE FOR INVESTMENT
The first half of Niti Aayog’s Investment Friendly Index 2026 report highlights Tamil Nadu’s success story, but the report also has some suggestions that could be read as a governance mission plan by the Tamil Nadu government to improve the state’s accreditation as investment friendly.
According to the Niti Aayog report, the financial health of Tamil Nadu is a major concern. The report reveals that the State’s outstanding liabilities amount to 31% of its Gross State Domestic Product (GDP).
Tamil Nadu’s GSDP is close to the national average (the average for large states is 30.3%), but it is high enough to affect the state’s financial health score.
Interest payments, which represent 3.4% of GDPD, have also been highlighted in the report as an area where fiscal discipline could improve the state’s investment credentials.
The report also identifies critical gaps in logistics even though Tamil Nadu ranks first in infrastructure among large states. It notes that the state’s container freight station (CFS) and inland container depot (ICD) capacity is 33% below the average of large states relative to their manufacturing output, creating a bottleneck in cargo movement.
Around the Chennai port, inadequate road infrastructure continues to cause severe congestion; Trucks reportedly wait up to 36 hours to enter or leave the port, increasing logistics costs for businesses in the state.
Another area that the Niti Aayog report says requires urgent attention is aviation infrastructure. The report reveals that the Chennai airport needs significant expansion to keep pace with the state’s growing industrial economy. He specifically points out the limited international connectivity, particularly the lack of direct flights to several European destinations, even though Tamil Nadu is home to many European multinational companies.
Water security also emerges as a long-term challenge for investors. The report highlights difficulties in securing industrial water supply in several parts of the state and notes the limited availability of treated wastewater for industrial reuse, especially in landlocked and landlocked regions. It suggests that improving wastewater treatment and expanding water recycling infrastructure would make industrial growth more sustainable.
FACTORS THAT MAKE TAMIL NADU FRIENDLY FOR INVESTORS
Niti Aayog has also credited Tamil Nadu for maintaining one of the strongest innovation ecosystems in India, backed by the second largest number of Atal Tinkering Labs, almost 100% conversion of investment MoUs into operational projects and a policy coherence that has earned the trust of investors over the years.
The electric vehicle policy was especially highlighted in the report as a model to attract global manufacturers through tailored incentive packages. These efforts were complemented by the state’s large pool of skilled talent produced by engineering colleges, ITIs and polytechnics, along with industrial infrastructure developed by SIDCO and SIPCOT and investor facilitation systems like Biz Buddy and Guidance Tamil Nadu Investor Facilitation Portal, which offers time-bound grievance redressal.
The state’s economic credentials are equally impressive. Tamil Nadu’s export-to-GSDP ratio is 36% higher than the large state average, while it attracted $2.436 billion in foreign direct investment (FDI) during FY24. It also topped the environmental resilience pillar, with air quality 22% better than the category average and strong stakeholder confidence in its disaster preparedness mechanisms.
Taken together, the shortcomings form the NITI Aayog’s roadmap for Tamil Nadu’s next phase of reforms. For Chief Minister C. Joseph Vijay, whose governance narrative has focused on efficiency, execution and results, the report offers more than a ranking. It sets out the specific tasks that could transform Tamil Nadu from a high-performing state to one of the most investment-friendly states in India.
