Thresholds represent an agreed-upon level of unsecured exposure a party is willing to accept before requiring collateral. A higher threshold indicates a higher tolerance for unsecured exposure based on the counterparty’s creditworthiness. On the other hand, independent amounts (initial margins) are security deposits required to protect against potential future exposure arising from market movements that could occur from the time of the last collateral call until the positions can be closed out or replaced in the event of a counterparty’s default. They are set independently of the current exposure and are aimed at mitigating potential future risk.

These two concepts operate based on different principles and serve distinct purposes in the management of credit risk in derivative transactions. While thresholds are about tolerating a certain level of current unsecured exposure based on trust and credit assessment, independent amounts are about proactively securing against potential future exposure regardless of current levels of trust or creditworthiness. Therefore, their movements or adjustments are not aligned in a manner where one could say they move in the same direction, are equal, or that one is always less than or equal to the other.

Things to Remember

• In a Credit Support Annex (CSA), thresholds and independent amounts serve different purposes and move in opposite directions in terms of their impact on collateral requirements.
• A threshold is the level of exposure above which collateral must be posted. It acts as a buffer before collateral requirements are triggered.
• An independent amount, often resembling a form of initial margin, is usually required to be posted upfront, regardless of the current exposure level.
• The relationship between thresholds and independent amounts is critical in understanding the overall collateral arrangement in derivative transactions.
• These components of the CSA are tailored to the creditworthiness and risk profiles of the counterparties, affecting the liquidity and credit risk management strategies.
