Template:Csa transaction versus credit support document
Profound onotological differences
Unlike a title transfer English law CSA, the 2016 NY Law VM CSA is not a Transaction under the ISDA Master Agreement, but is in fact a Credit Support Document: a standalone collateral arrangement that stands aloof and apart from the ISDA Master Agreement and all its little diabolical Transactions, and the reason for that is — and, spoiler: it’s not a very good one — because while a English law CSA, by being a title transfer collateral arrangement, reverses the indebtedness claim outright, an 2016 NY Law VM CSA (and, for that matter, an English law Credit Support Deed) does not: it only provides a security interest. The in-the-money counterparty is still in-the-money. It is just secured for that exposure. The outright exposure between the parties does not change.
This is deep, magical, bamboozling stuff and, at least where rehypoethcation is allowed under Paragraph 9(c) of a 2016 NY Law VM CSA — it pretty much always is — serves no real pupose at all, because even though you say you are only pledging the agreement, in the the greasy light of commercial reality, you are transferring title outright.
