Meaning
Documents governing the exchange of collateral between counterparties in over-the-counter derivative transactions mitigate the risk of financial loss. The isda credit support annex functions as a legal bridge that links the value of a trade to the security provided by the participants. If the market moves against one party, they must post cash or bonds to cover the potential debt.
This ensures that the surviving firm is protected if the other side goes bankrupt.
Collateral Requirement
Assets pledged under the agreement act as a safety net for the transaction. The isda credit support annex specifies which types of securities are acceptable for covering exposure. Most firms prefer cash or high grade government debt because these are easy to value and sell.
Valuation Frequency
Regular checks of the market price determine how much security must be held at any given time. Under the isda credit support annex, counterparties recalculate their exposure daily or weekly. This frequent monitoring prevents a large deficit from building up over time.
Threshold Management
Minimum levels of exposure must be reached before a margin call is triggered. The isda credit support annex defines these limits to prevent small, daily transfers that would be too expensive to process. Once the debt crosses the threshold, the borrower must send enough collateral to bring the balance back to zero.
