Fresh updates from the financial markets indicate that Tata Chemicals shares hit 20% upper circuit on September 15 as notes stated Reserve Bank of India has rejected an application from Tata Sons to deregister as a non-bank lender, a decision that leaves the firm closer to a equity market stock-exchange debut.

Tata Sons had applied to the RBI to deregister as a core investment firm due to regulations that potentially require it to list.

The more than a century-old holding firm, which controls businesses including Tata Consultancy Services, Tata Motors, Tata Steel and Air India, has sought to stay privately held.

It is classified as a core investment firm and falls under RBI regulations for non-bank lenders, which require that firms with assets exceeding Rs 1 lakh crore, or those with direct or indirect access to public funds, must list.

As of March 2025, Tata Sons' standalone assets totalled Rs 1.75 lakh crore.

Shares of Tata Chemicals are locked in a 20% upper circuit, while those of Tata Investment Corporation are trading with upside of over 13% on September 15. Both stocks are the top two gainers on the Nifty 500 index on Tuesday. Shares of Tata Motors Passenger Vehicles are additionally trading with upside of 4.5%, while those of Tata Steel are trading with modest upside.

Among the listed Tata Group firms, Tata Steel and Tata Motors Passenger Vehicles have a 3.06% stake each in Tata Sons, while Tata Chemicals holds a 2.53% stake. Tata Power has a 1.65% stake, while Indian Hotels, Tata Consumer and Tata Investment own 1.11%, 0.4% and 0.25%, respectively.

The rejection was conveyed in a letter received by Tata Sons’ firm secretary and chief financial officer on Saturday, sources told PTI, closing out an application the firm filed in March 2024 seeking to deregister as a non-banking financial firm.

The decision means Tata Sons will stay classified as an Upper Layer NBFC, a category subject to enhanced regulatory requirements, including mandatory stock-exchange debut. The RBI first classified Tata Sons as an Upper Layer NBFC in September 2022, with such entities required to list within three years. The original deadline for Tata Sons was September 30, 2025.

Tata Sons had sought to exit the NBFC framework before that deadline. It repaid more than Rs 21,000 crore of debt in 2024 and applied to surrender its registration, effectively seeking to operate as an unregulated holding firm rather than comply with the stock-exchange debut requirement. The RBI kept the application pending and continued to include Tata Sons in its Upper Layer NBFC lists.

The central bank’s rejection now removes the key regulatory route Tata Sons had been pursuing to stay private. The firm has assets well above the Rs 1 lakh crore threshold under the RBI’s revised framework for automatically qualifying large NBFCs for the Upper Layer, making an exemption increasingly difficult.

A public stock-exchange debut would mark a fundamental change for the holding firm of one of India’s oldest and largest business groups. Tata Sons owns significant stakes in listed and unlisted Tata firms spanning information technology, automobiles, steel, consumer products, aviation, hospitality and financial services.

The move could additionally bring far greater scrutiny of Tata Sons’ finances, capital allocation and investments. A listed holding firm would face regular disclosure requirements and greater pressure from public shareholders for clarity on the value of its investments and returns on capital.

The roots of the current offering trace back to October 2021, when the RBI introduced a scale-based regulatory framework for NBFCs, sorting lenders into base, middle, upper and top layers with progressively stricter oversight.

In September 2022, the central bank placed Tata Sons – alongside firms including Bajaj Finance and Shriram Finance in the Upper Layer category, a classification that carries a hard three-year deadline to list on the bourses, originally due to expire on September 30, 2025.

Tata Sons pushed back. It repaid more than Rs 21,000 crore of debt in 2024, becoming debt-free, and filed to surrender its Core Investment Firm registration altogether – a move that, if approved, would have let it exit the NBFC framework entirely and stay privately held. The RBI left the application pending through 2025, even as it kept including Tata Sons on successive Upper Layer lists, each time noting the stock-exchange debut did not affect the outcome of the deregistration review.
