Division of Clearing and Risk staff issued an interpretation providing clarification that while regulation 22.2(d) prohibits an FCM from permitting a lien on Cleared Swaps Customer Collateral that it holds, regulation 22.2(d) does not prohibit a Cleared Swaps Customer from granting a lien on his or her own account at the FCM, nor does the regulation prohibit the FCM from taking action to foster the Cleared Swaps Customer’s grant of such a lien.
