India’s capital-markets regulator has fined BSE Ltd. ₹25 lakh after finding the country’s premier stock exchange failed to give all investors simultaneous access to price-sensitive corporate disclosures and was lax in monitoring frequent broker trade modifications. In a 45-page order released Wednesday, the Securities and Exchange Board of India said a system architecture flaw let BSE’s paid subscribers and its listing-compliance staff see company announcements before they were posted publicly on the exchange’s website. SEBI also flagged inadequate oversight of so-called client-code changes, saying BSE did not act against brokers that repeatedly altered trades. The regulator’s findings stem from an inspection covering February 2021 to September 2022. BSE said in an exchange filing that the order will have no material impact on its financial or operational activities.
