Crossing Network / Dark Pool
A dark pool or crossing network is a private venue where large orders are matched without pre-trade transparency, allowing institutions to trade size without revealing intent, a model tightly limited in India.
In developed markets, dark pools let institutions cross large blocks anonymously to avoid market impact. India does not permit lit-market-style dark pools; instead, large trades use the regulated block-deal window and negotiated deals, which provide post-trade disclosure rather than fully dark execution.
Understanding dark pools helps Indian investors interpret global market structure debates around transparency and fragmentation. The Indian approach favours on-exchange transparency, channelling block liquidity through disclosed mechanisms rather than off-exchange dark venues, with SOR operating only across the lit NSE and BSE.
