The Central Government has appointed former Indian Space Research Organisation Chairman S Somanath to the Central Board of the Reserve Bank of India, bringing a career rooted in space technology and public institutions into the country’s central bank governance structure.
The appointment took effect on August 20, 2026, and will run for four years or until further orders, whichever comes earlier, according to an official announcement issued by the Reserve Bank of India.
In a separate order issued on the same day, the government also reappointed Mahindra Group Chairman Anand Gopal Mahindra as a part-time Non-Official Director on the RBI Central Board. His new term will also run for four years from August 20, subject to the same condition. The RBI confirmed the reappointment through a separate press release.
For the RBI, that mix is part of how its Central Board is structured. The board includes the Governor, Deputy Governors, government nominees and directors drawn from fields outside the central bank.
From ISRO to RBI: Somanath Takes On a Different Public Role
Somanath served as ISRO Chairman and Secretary of the Department of Space from January 2022 to January 2025.
His tenure covered a period in which India completed the Chandrayaan-3 lunar landing, put the Aditya-L1 solar mission into operation and moved ahead with work related to Gaganyaan, launch vehicles and the opening of the space sector to private companies.
ISRO’s profile of Somanath says he spent close to four decades working in space technology and launch vehicle systems. Before becoming ISRO Chairman, he headed the Vikram Sarabhai Space Centre and the Liquid Propulsion Systems Centre.
He is currently a Vikram Sarabhai Distinguished Professor at ISRO, according to the space agency’s official profile of its former chairman.
His RBI appointment is therefore not a continuation of his space-sector responsibilities. It places him in a board-level role at an institution responsible for banking regulation, currency management, payment systems, financial supervision and other parts of India’s financial system.
What Does a Non-Official Director on the RBI Central Board Do?
The term "Non-Official Director" can easily create confusion.
Somanath has not been appointed as an RBI Deputy Governor. He has also not been appointed to the Monetary Policy Committee simply because he has joined the Central Board.
The Central Board is the body responsible for the general direction and oversight of the Reserve Bank’s affairs.
The RBI’s description of its organisation structure says the board is appointed by the Government of India under the Reserve Bank of India Act, 1934. It includes the Governor and up to four Deputy Governors as full-time officials, along with directors nominated by the government and representatives linked to the RBI’s Local Boards.
The Central Board deals with the governance of the institution. The Monetary Policy Committee, on the other hand, has a separate legal structure and is responsible for deciding the policy repo rate and the monetary policy stance.
Why Somanath’s Appointment Stands Out
The choice of a former space agency chief for the central bank board cuts across institutional boundaries that usually remain separate.
Somanath’s career has largely been built around engineering, programme management, launch systems and public technology missions rather than finance.
At ISRO, he was involved not only in missions but also in the changes taking place in India’s space sector, including engagement with private companies and start-ups.
That experience comes at a time when the financial system itself is becoming more dependent on technology.
News4Bharat recently explained several of these changes in its guide to RBI and NPCI UPI rules in 2026, including biometric authentication and payment security requirements.
Somanath’s appointment should not be read as a signal that he will personally run these areas. The government and RBI have not assigned any such specific responsibility to him. But his presence adds a technology and systems background to the board at a time when such questions form a growing part of financial regulation.
Anand Mahindra Gets Another Four Years
Alongside Somanath’s appointment, the government has given Anand Mahindra another four-year term on the RBI Central Board.
Mahindra was first nominated to the board in June 2022 along with other part-time Non-Official Directors.
His reappointment means he will continue on the board from August 20, 2026, for another four years unless the government issues further orders before the end of the term.
Mahindra chairs the Mahindra Group, whose businesses span automobiles, farm equipment, financial services, technology and other sectors.
The reappointment also provides continuity on the board at the same time that Somanath enters it.
Mahindra Group has itself been making changes to its leadership structure.
News4Bharat recently reported on Shveta Arya joining Mahindra as Group Strategy Chief as the group works across its automotive, farm, finance, technology and services businesses.
Who Sits on the RBI Central Board?
Under the RBI Act, the Central Board combines full-time central bank officials with directors nominated by the government.
The RBI says the structure can include:
- the RBI Governor
- up to four Deputy Governors
- ten directors nominated by the Central Government from different fields
- two government officials
- four directors linked to the four Local Boards
The board’s role is broader than setting interest rates. RBI documents describe its responsibility as the general superintendence and direction of the central bank’s affairs.
This covers the institution that supervises banks, manages currency, regulates payment systems, manages foreign exchange functions and carries out several other responsibilities under different laws.

What Happens Next?
Both appointments are already in effect from August 20, 2026.
Somanath begins a four-year term as a part-time Non-Official Director, while Mahindra begins another four-year term following his reappointment.
There has been no announcement giving Somanath a separate executive function inside the RBI or a seat on the Monetary Policy Committee.
The immediate change is at the level of the Central Board itself.
For Somanath, it marks a move from leading India’s space agency to participating in the governance of its central bank. For the RBI board, it adds another professional background to a body designed to bring together central bankers, government representatives and people from outside the institution.
