Ajay Tyagi hit the ground running in his new assignment as chairman of the Securities and Exchange Board of India (Sebi). In less than a month in office, Sebi had passed the long-pending order against Reliance Industries in a 10-year-old case of unlawful gains. The market regulator imposed a penalty of over Rs 10 billion, including interest, on the country’s biggest company, sending a signal that the former bureaucrat would not shy away from taking bold decisions. Besides Reliance, Tyagi also had to deal with cases involving high-profile entities, including Tata Sons and Infosys, at the start of his tenure.
