SEBI proposes STP overhaul

India’s securities regulator has opened a market-plumbing debate that matters more than the phrase “straight-through processing” suggests. On May 19, the Securities and Exchange Board of India proposed replacing the current centralized STP hub used for institutional trades with a decentralized, API-based framework. SEBI said the change is meant to reduce delays, lower costs and cut concentration and operational risks in a part of the market that sits between trade execution and settlement. (sebi.gov.in) The proposal is still at consultation stage, but it points to a clear redesign of how post-trade instructions would move among brokers, custodians and other participants. (moneycontrol.com) Instead of routing through a single hub model, SEBI wants direct connectivity between STP service providers under common industry standards. (sebi.gov.in) ### What is SEBI actually trying to change in the current setup? SEBI’s May 19 consultation paper proposes scrapping the centralized STP Hub architecture that institutional market participants currently use for transaction processing. In its place, the regulator outlined a decentralized model based on application programming interfaces, or APIs, linking STP service providers directly. (sebi.gov.in) The current issue, as described in coverage of the proposal, is not only speed. SEBI also tied the redesign to concentration risk and dependence on a single infrastructure layer, alongside the need to improve service delivery for market participants. ### Why does an API-based model matter in a post-trade system? (sebi.gov.in) A decentralized API model changes the mechanics of how messages move after a trade is executed. Business Today and other reports summarizing the consultation paper said SEBI expects the shift to reduce costs, improve efficiency and speed up processing by removing the centralized hub from the middle of the workflow. For firms that build or maintain post-trade systems, that means the work moves from integrating with one central pipe to managing cleaner interfaces across multiple counterparties under a common rulebook. (sebi.gov.in) That is an inference from SEBI’s proposed design and from the regulator’s emphasis on operational standards, messaging formats and direct connectivity. (legal.economictimes.indiatimes.com) ### Who will write the operating rules if SEBI approves the redesign? The Industry Standards Forum, a body of market infrastructure institutions, has been tasked with developing the detailed framework in consultation with SEBI. Moneycontrol reported that the assignment covers standard operating procedures, messaging formats and operational standards for the new model. (businesstoday.in) That division of labor matters because SEBI is proposing the architecture, but the industry body would define much of the operating detail needed to make different systems talk to each other consistently. The consultation paper indicates those details would sit at the center of implementation. (sebi.gov.in) ### Where would firms feel the change first? Institutional transaction-processing teams would likely see the first impact in exception handling, reconciliation flows and interface management. SEBI’s proposal is aimed at institutional stock market transactions, and the redesign would affect the path those instructions take after a trade is executed. (moneycontrol.com) Technology teams at brokers, custodians and service providers would also need to align around common message formats and operating procedures if the framework goes ahead. That follows directly from SEBI’s plan to have the Industry Standards Forum draft those standards. ### What happens next, and when? (sebi.gov.in) June 9, 2026, is the immediate date to watch. SEBI’s consultation paper invites public feedback until then through its public-comment process. Any final framework would come after that consultation window and after the Industry Standards Forum’s work on procedures, messaging and operating standards. For now, the live document is SEBI’s May 19 consultation paper on easing the framework for straight-through processing of trades. (legal.economictimes.indiatimes.com) (sebi.gov.in) (moneycontrol.com)
