SEBI proposes uniform pricing for illiquid stocks across exchanges
Synopsis
Key Takeaways
The Securities and Exchange Board of India (SEBI) on Thursday, 11 June released a consultation paper proposing a new cross-exchange pricing mechanism to prevent the same stock from trading at materially different prices on different platforms. The proposal primarily targets illiquid and small-cap stocks that do not trade regularly across all exchanges.
The Core Problem SEBI Is Addressing
Under the current framework, each exchange independently calculates circuit limits based on its own previous closing price. When a stock goes inactive on one exchange while continuing to trade on another, the inactive platform's price and circuit bands freeze — creating two divergent market prices for the same security. This structural gap can restrict trading and distort price discovery for retail and institutional investors alike.
What SEBI Has Proposed
SEBI's consultation paper recommends that when a stock is inactive on one exchange but active on another, the inactive exchange should adopt the active exchange's closing price as the base price for the next day's pre-open session and apply price bands accordingly. The regulator stated: 'The previous day closing price of the scrip is taken as the base price for the pre-open session of a scrip and the price bands as discussed above are applicable on the said base price.'
Additionally, if a stock trades on more than one exchange but remains inactive on one of them, the inactive exchange should adopt the closing price from the exchange recording the highest trading volume. To operationalise this, exchanges would be required to establish formal arrangements for sharing closing-price data with each other.
Who Is Affected
The proposed changes are expected to have the most significant impact on illiquid and small-cap stocks that do not see consistent activity across all listed exchanges. Actively traded, large-cap securities are unlikely to be materially affected, as they typically maintain price parity across platforms through continuous arbitrage.
Broader Market Infrastructure Goals
SEBI framed the initiative as part of its wider effort to strengthen market infrastructure by improving price discovery and eliminating structural inefficiencies. Notably, this follows a broader regulatory push in recent years to tighten oversight of thinly traded securities, which have historically been susceptible to price manipulation and artificial circuit-limit exploitation.
If adopted, the mechanism could make trading in illiquid stocks more seamless for investors while reducing artificial price gaps and execution hurdles across exchanges.
Timeline and Next Steps
Public comments on the consultation paper are open until 2 July. SEBI will review stakeholder feedback before deciding on final implementation. Market participants, exchange operators, and investor associations are expected to submit responses ahead of the deadline.
