Meaning
Contractual frameworks established among a borrower, a lender, and an independent third-party agent govern the custody, valuation, and settlement of collateralized transactions. Within a triparty agreement, the agent takes responsibility for verifying that the collateral posted by the borrower meets the risk criteria and value thresholds set by the lender. This arrangement reduces the operational burden on the transacting counterparties by automating margin calls and asset substitutions.
Custody Service
Securitized assets are held in segregated accounts managed by the triparty agent to protect them from the insolvency of either counterparty. The agent performs daily valuations and ensures that the total value of the assets, adjusted for haircuts, exceeds the outstanding transaction exposure. This segregation minimizes the risk of collateral rehypothecation or loss.
Risk Monitoring
Automatic margin matching systems monitor the collateral pool constantly to trigger adjustments when values decline. If the borrower fails to maintain the required margin, the system generates automated margin calls to restore the required coverage levels. This proactive surveillance protects the lender from sudden borrower default.
Operational Flow
Settlement of these transactions relies on the automated infrastructure provided by the agent bank. This automation reduces the administrative cost of managing complex collateral pools.
