Mumbai: The Securities and Exchange Board of India (Sebi) has waived margin requirements for trades using proceeds from sales under the early pay-in (EPI) mechanism, a move aimed at easing margin-funding requirements. In a circular issued on Thursday, the capital markets regulator said clearing corporations must, in real time, refrain from collecting margin from trading members and clearing members on subsequent positions taken by clients, up to the value of EPI accepted by the clearing corporation.
