Meaning
A financial institution category that holds a restricted license to access a central counterparty for the purpose of settling specific transaction classes without fulfilling the full capital requirements of a general clearing participant. An ancillary clearing member usually operates under a parent entity or within a defined niche such as energy derivatives or commodities. This arrangement ensures that specialized market players maintain direct access to clearing without overextending their balance sheets or assuming the mutualized risks of broader market segments.
Participation Limit
Risk exposure is restricted to the specific collateral pools or volume caps defined in the membership agreement. This status allows a firm to clear its own house trades while preventing it from offering clearing services to external clients or third parties.
Capital Requirement
Reduced liquidity buffers and lower default fund contributions characterize this tier of membership. Because the ancillary clearing member does not pose a systemic risk to the entire clearing house, the central counterparty applies a more granular margin model.
Default Allocation
Liability for the losses of other participants is strictly limited or entirely waived in exchange for the restricted trading scope. Should the clearing house face a liquidity crisis, this member contributes only to the specific waterfall segments it occupies.
