Who is the current Finance Secretary of India?

"Finance Secretary" is not a standalone post in the Government of India — it is a coordinating designation conventionally given to the senior-most among the five secretary-level officers within the Ministry of Finance (heading the Departments of Economic Affairs, Expenditure, Revenue, Financial Services, and Investment & Public Asset Management / DIPAM). Which of the five actually holds it changes whenever the government reassigns seniority, so answering this question means pinning down WHO carried the title on the exam's reference date, not just who worked somewhere in the Finance Ministry.

For this Coal India 2020 (Electrical branch) paper, the reference date falls in the window when Rajiv Kumar, Secretary of the Department of Financial Services, carried the coordinating "Finance Secretary" designation — from around August 2019, when he succeeded Subhash Chandra Garg, until his retirement at the end of February 2020.

• Rajiv Gauba was Cabinet Secretary of India during this period, having taken charge in August 2019 — the apex, all-ministry coordinating post, distinct from and senior to any single ministry's own secretary.

• Subhash Chandra Garg held the Finance Ministry's coordinating designation earlier (as Economic Affairs Secretary) but was moved out to the Ministry of Power in July 2019, and later retired from service, so he was not in the role at the exam's reference point.

• Atanu Chakraborty became Secretary, Department of Economic Affairs, within the Finance Ministry around this period — one of the five secretary-level charges, but not the officer carrying the coordinating title in this window.

So, for the period this exam refers to, the current Finance Secretary of India was Rajiv Kumar.
