QuoteOriginally posted by: DavidJNTo understand what is possible one needs to consider the relevant legal documentation. The set of available currencies for collateral movements is defined in legal terms in the Credit Support Annexes (CSAs) to the ISDA Master Agreements signed between counterparties. Once that documentation is in place the only guiding principle for collateral choice should be the cheapest-to-deliver notion described by Martinghoul. Any other kind of decision criterion is financially suboptimal.So, if you are positing some kind of systematic preference for the collateral movement currency for a specific counterparty, that preference would be have to show up in the CSA documentation. You would also have to believe in less than optimizing behaviour, unless of course the currency preference just happens to be the cheapest-to deliver currency. Seeing as the collateral currency choice is presumably available to both counterparties, a given counterparty can only control what currency they use to post collateral, they cannot choose the currency in which they receive collateral.Thanks David for the reply.This is all true. In my perception, multi-currency CSA in western hemisphere are mostly USD+EUR+GBP based. But I am pretty sure that Australian banks negotiated also AUD in their CSAs as well as Japanese banks negotiated JPY. The question is what they actually currently prefer when they have a choice of 4 currencies?
