The optimal solution proposed is a collateral reporting mechanism between custodians and clearing members, wherein clearing corporations and exchanges agree on a mechanism to implement a pre-trade check that ensures that any trades that cross, say, 90 per cent margin utilisation will not be executed for lack of sufficient margin. To address any concerns from high-frequency trading clients on the latency of trade execution, pre-trade checks will be immediate and margin allocation will be on a ‘first come first served’ basis, with only the last trade that crosses the 90 per cent margin utilisation cap being rejected.
The second solution suggested is that confirmation on peak margin at various snapshots should be taken from the custodians instead of TMs on the basis of the custodial participant (CP) code allotted to clients. The penalty for shortfall in margin would be levied at CP level and collected from custodians. TMs should be responsible for the trade erroneously booked on behalf of clients and should be responsible for the shortfall and penalty once identified.
