India’s new closing auction reveals market pressure but exposes gaps in liquidity and data transparency; structural reforms are needed to optimise its effectiveness and stability.
India’s new closing auction is doing what auctions often do: exposing the market’s true pressure at the end of the session. On its first day, benchmark indices finished far from their 3.15pm levels, and trading desks spent the evening trying to work out who had traded and at what price. Since then, the last 15 minutes have drawn far more attention, especially around weekly derivatives expiry, as market participants test whether the mechanism can reliably produce a stable close.
That uncertainty is not necessarily a flaw. As Nasdaq’s auction framework shows, a closing cross is designed to match supply and demand, then publish an indicative equilibrium price and imbalance data so traders can respond to the same information at the same time. The trouble in India is less the auction itself than the supporting market structure around it. The current rules provide a price band, a randomised close and a published close price, but they do not yet give the market enough tools to absorb one-sided order flow.
One missing piece is an order type built to lean against imbalances rather than create them. Nasdaq’s imbalance-only close orders are designed to interact only with excess supply or demand already in the book, and they are part of a wider set of closing-cross order types that help liquidity providers participate without worsening the squeeze. On the New York Stock Exchange, closing discretionary orders have become increasingly important, and the exchange says they accounted for more than 46% of closing-auction volume by August 2024. Reuters and exchange data both point to the same lesson: late liquidity matters, but it has to be channelled in a way that does not distort the close.
Transparency is the next requirement. Nasdaq disseminates paired volume, imbalance and indicative price information at regular intervals before the close, while the New York exchange has moved to faster updates and earlier inclusion of discretionary orders in the imbalance feed. For India, the lesson is that the same data must reach retail terminals and co-located traders simultaneously, with clear timing and content. Without a shared view of the imbalance, the market is forced to guess rather than price.
The deeper structural problem is on the sell side. Buying into a buy-heavy auction is mostly a question of cash, which participants can arrange relatively easily. Selling requires stock, and in India the securities lending and borrowing framework is still too narrow to support the job the auction is being asked to do. As the article notes, lending is available for only a small fraction of listed companies, collateral demands are heavy and recall rights are limited. That means the close can remain lopsided unless borrowing becomes easier and more widely available.
The right response is not to abandon the auction, but to complete it. India now needs an imbalance-absorbing order type, real-time auction data for all participants, a liquidity scheme tailored to the close, and a deeper lending market that can actually supply sellers. Without those additions, the auction will keep revealing pressure that the market cannot yet absorb.
