Shares can reach your demat account before you pay in full. An attached pledge can keep them out of your freely available balance.
The revised framework was announced in July. Its main changes take effect on October 31, 2026.
The Breakdown
The existing mechanism credits unpaid shares outside the Margin Trading Facility directly to the client’s demat account with an automatic pledge to the broker’s Client Unpaid Securities Pledgee Account, or CUSPA. The broker must communicate the payment obligation and its right to sell on default.
Fully paid shares cannot be marked as unpaid through this mechanism. Its rules should not be applied to every ordinary margin pledge or financed holding.
Five days is a ceiling
The broker’s payment deadline cannot exceed five trading days from securities payout, but it can be shorter. On default, the broker can invoke the pledge and liquidate the shares after reasonable notice.
So a demat credit does not make the shares freely transferable or guarantee that they can be sold without the applicable pledge process. Nor may the broker offer further trading exposure against these unpaid holdings, even when their value counts in margin reporting.
Release has its own rules
Under the revised framework, a pledge left neither invoked nor released within five trading days after payout is automatically released at the end of the sixth trading day. These are trading days counted after payout, not calendar days from the purchase.
Brokers must also assess the permissible pledge daily and release excess holdings by the next trading day.
Separate provisions for extending pledges when liquidation is prevented by specified exceptional circumstances begin on January 3, 2027. They should not be treated as available under the October implementation.
The Crunch
The useful check is the holding’s status alongside the broker’s payment policy. An account balance alone cannot tell you whether the shares are available for another transaction.
Context added October 30, 2026
NSE’s inspection observations, updated on October 28, list fully paid securities being pledged in CUSPA among irregularities found in trading members’ books for October 2025 to March 2026. The page does not identify the brokers involved or quantify how often this occurred. It therefore cannot establish whether a particular investor’s holdings are affected.
