Blockchain-Based Repo Markets
Blockchain-based repo markets represent an innovative evolution of traditional repurchase agreements, leveraging distributed ledger technology to automate collateral management, enhance settlement efficiency, and reduce counterparty risk. These systems use smart contracts to execute repo transactions with real-time settlement and automated margin calls.
How blockchain transforms repo markets
Traditional repo markets face several operational challenges, including manual processes, settlement delays, and complex collateral management. Blockchain technology addresses these issues through:
- Automated collateral management
- Real-time settlement
- Smart contract-driven margin calls
- Transparent transaction records
Key components of blockchain repo platforms
Smart contract automation
Smart contracts govern the entire repo lifecycle, automatically executing:
- Initial collateral transfer
- Interest payments
