Enhanced supervision clarifications: voluntary proprietary account naming, depository-only pledges, and tightened margin and reporting rules. The circular amends enhanced supervision requirements: naming of proprietary bank/demat accounts is voluntary while accounts not falling under specified client or third party categories are deemed proprietary; bank stock brokers need report only accounts used for broking; pledging of client securities is permitted only through the depository system in compliance with depository regulations; brokers must not grant further exposure when debit balances persist beyond the fifth trading day from pay in except under the prescribed margin trading facility; data upload frequency is monthly until the specified cut off and weekly thereafter; regional commodity exchanges are exempt until further notice.
