Earlier this month, NSE announced the induction of Chawla and Dharmishta Raval into its board as public interest directors.
The exchange is now awaiting nod from the Securities and Exchange Board of India (Sebi) for appointing Chawla as the chairman.
When contacted, the exchange's spokesperson said its Nomination and Remuneration Committee (NRC) has proposed the name of Chawla as chairman and is awaiting Sebi's approval.
An experienced civil servant, Chawla retired as Competition Commission of India (CCI) chairman in January after being at the helm for nearly five years. He has also served as Finance Secretary and Civil Aviation Secretary, among other posts.
At NSE, four public interest directors -- S B Mathur, Y H Malegam, K R S Murthy and S Sadagopan -- completed their terms recently. Mathur was the bourse's chairman.
A leading exchange, NSE has been in existence for 20 years and its flagship index Nifty50 is used extensively by investors in India and overseas.
