Problems
Problem 1: Counterparty Exposure
Repo counterparty relationships reveal funding dependencies and credit relationships. Public exposure enables competitors to target funding sources or exploit perceived credit weakness.
Requirements:
- Must hide: Counterparty identities, transaction amounts, collateral details, rates
- Public OK: Aggregate market statistics, general market rates
- Regulator access: Systemic risk monitoring, counterparty exposure aggregation, collateral sufficiency
Constraints:
- Same-day (often intraday) settlement requirements
- Collateral eligibility and haircut calculations
- Netting and novation for clearing
- Central bank facility access requirements
Problem 2: Funding Cost Arbitrage Prevention
Visible funding costs and patterns enable competitors to undercut pricing or front-run funding needs.
Requirements:
- Must hide: Specific rates obtained, funding frequency, rollover patterns
- Public OK: Reference rates (SOFR, repo indices)
- Regulator access: Rate surveillance, market manipulation monitoring
Constraints:
- Real-time pricing requirements
- Integration with existing repo infrastructure
- Tri-party vs bilateral repo differences
Recommended Approaches
Approach TBD. Consider:
- Privacy-preserving collateral verification
- Atomic settlement with privacy (similar to DvP patterns in Private Bond Issuance & Trading)
- Integration with existing clearing infrastructure
Open Questions
- How do intraday settlement requirements interact with privacy mechanisms?
- What's the migration path from centralized repo infrastructure?
- How to handle collateral substitution with position privacy?
