Reminder, changes in the Calculation of the National Securities Clearing Corporation’s Excess Capital Premium Charge take effect TODAY.

The Excess Capital Premium (ECP) charge is a component of the Clearing Fund that is designed to mitigate the heightened default risk a member could pose to NSCC if it operates with lower capital levels relative to its margin requirements.

From FiveEggHeads in one of the linked posts for background:

We’re putting a cap on excess capital, evaluating your positions based on net, if you are drowning, we are not going to come to the rescue and waive the premium charges like we did from January 28th to February 1st, 2021.
The counterpoint that’s buried deep in the doc to waiving or reducing the premium charges – they will accept members position statements to determine the appropriate charges to apply, but even they call out if they don’t have updated statements they will use what they have available .
