If you mark a collateral hold on your shares on T day,  you can release it on the same day in case you have not sold such shares or have not taken any position against them. Such shares will be released to the same Demat account from where you have marked hold on them. From T+1 day onwards, you can partially or fully withdraw such shares (subject to margin availability) and the same will be released back to your Demat account at the end of the day.  In case you are maintaining a running account with us, shares which you hold as collateral will be released at the end of the month or the quarter depending upon the settlement preference selected by you.

Note - In case you have mapped multiple Demat accounts to your trading account, such shares will be released back to your default Demat account at the end of the day in case you have given withdrawal request online. Also in case of monthly or quarterly settlement of securities, shares lying unused in collateral account are released back to default Demat account
