It is this "eligible collateral profile" that enables the repo buyer to define their risk appetite in respect of the collateral that they are prepared to hold against their cash. For example, a more risk averse repo buyer may wish to only hold "on-the-run" government bonds as collateral. In the event of a liquidation event of the repo seller the collateral is highly liquid thus enabling the repo buyer to sell the collateral quickly. A less risk averse repo buyer may be prepared to take non investment grade bonds or equities as collateral, which may be less liquid and may suffer a higher price volatility in the event of a repo seller default, making it more difficult for the repo buyer to sell the collateral and recover their cash. The tri-party agents are able to offer sophisticated collateral eligibility filters which allow the repo buyer to create these "eligible collateral profiles" which can systemically generate collateral pools which reflect the buyer's risk appetite.
