CAS chaos triggers liquidity spiral: Nuvama says higher participation needed to break cycle
Economic Times 1 hr ago·22 Aug 2026, 9:28 am
BSE’s new Closing Auction Session is facing a liquidity crisis, with Nuvama reporting a sharp drop in option premium volumes and contracts. This decline in participation is creating a self-reinforcing cycle where thin liquidity makes it harder for market makers to operate, further discouraging traders from participating.
The situation is being compounded by early confusion among retail investors and heightened scrutiny following allegations of CAS manipulation. For investors, this means the new closing-price mechanism may not function as intended, potentially leading to wider bid-ask spreads and increased volatility in the market.
Market participants are now closely watching the volume trends to see if the liquidity spiral can be broken. The success of the session will depend on whether brokerages and exchanges can address the concerns and encourage higher participation to stabilize the mechanism.
