Who is Madhabi Puri Buch, the markets regulator under attack from Hindenburg?

SEBI chief Madhabi Puri Buch faces Hindenburg Research allegations, known for tough regulatory stance and data-driven decisions.

The chief of India's markets regulator, Madhabi Puri Buch, who is under attack from Hindenburg Research following its accusations against the Adani Group, is renowned as a no-nonsense leader who is used to difficult situations.

The first woman at the helm of the Securities and Exchange Board of India, Ms. Buch has a tough, businesslike approach to her work, people who know her say.

On Saturday, Hindenburg alleged she had a conflict of interest in the Adani matter because of a previous investment in an offshore fund used by the Adani Group.

Ms. Buch countered saying the investments pre-date her term at SEBI and that all necessary disclosures were made.

She termed Hindenburg's allegations as an attempt at "character assassination" following the regulator's enforcement action and "show cause" notice to the U.S. based shortseller for violating Indian rules. A show cause notice signals an intention to take disciplinary action if satisfactory explanations are not provided.

If Ms. Buch made the requisite disclosures and met the compliance requirements, nothing more should be expected of her, said Hetal Dalal, chief operating officer at Institutional Investor Advisory Services, a proxy advisory firm in India.

“Nevertheless, the allegations made by Hindenburg have made her and SEBI vulnerable," Ms. Dalal said. "A regulator must ring fence itself from the public onslaught."
