Collateral arrangements

Describe common collateral arrangements for listed, cleared and uncleared equity derivatives transactions.

When a person effects a listed equity derivatives transaction, he or she must deposit clearing margin (which is calculated by deducting the total amount of the net option value from the Standard Portfolio Analysis of Risk Requirement, which is calculated via a risk simulation based on current portfolio values).

Clearing participants deposit clearing margin, which is the aggregate amount summing up the total margin amounts of all customers of the clearing participant.

Exchanging collateral

Must counterparties exchange collateral for some categories of equity derivatives transactions?

Yes, starting from September 2016, certain financial institutions must, in principle, exchange collateral when engaging in OTC derivatives transactions, including OTC equity derivatives transactions, with other financial institutions as counterparty. This obligation to exchange collateral is applied to any type of OTC derivatives transactions governed by the FIEA. Initially, this regulation is applied to the financial institutions with the larger volume of OTC derivatives and, gradually, the scope of this regulation is extended to the financial institutions with smaller volumes of OTC derivatives. The collateral to be exchanged is categorised into variation margin and initial margin. The amount to be exchanged as variation margin must be determined on a mark-to-market basis, and must be the current profit price that one party obtains. The amount of initial margin reflects the expected size of the potential future exposure to the other counterparty.

There are no statutes or laws that mandate an obligation to exchange independent amounts.
