The board of Sebi on Saturday relaxed some of the guidelines for small not-for-profit organisations (NPOs) and non-government organisations (NGOs) to tap the social stock exchanges (SSEs) to raise funds, including halving the minimum fund-raising size to Rs 50 lakh. The board also approved a regulatory framework for index providers “with the objective of fostering transparency and accountability in governance and administration of financial benchmarks in the securities market,” the market regulator said in a release.
