Whether CRTs have enough in common with this type of scenario to create a need for reform is a matter of debate. The commission's comments do make specific reference to synthetic securitization transactions involving special purpose entities, which suggests they might, but in other ways they are dissimilar.
"In these kinds of deals, you do have a SPE that's selling credit protection to a bank or a GSE for some reference pool of mortgages or other financial assets, and the bank or GSE is getting a premium for that," said Horn. "But that credit protection buying and selling feature is intrinsic to the deal and doesn't bear any family resemblance to the sorts of conflicts of interest that Section 27B was meant to address."
Credit risk transfers do have a selection process that may make them vulnerable to potential conflicts of interest, according to Calabria.
"Fannie and Freddie pick which loans go into those deals," said Calabria. So it's theoretically possible that someone on the GSE side, which is packaging the credit risk for sale, could purposefully put loans more likely to go into default into the reference pool.
However, DeMarco said the selection process for CRT pools has not been hidden as it was in the subprime mortgage transaction referenced in the proposal.
Originally, CRT reference pools aimed to match a particular GSE's distribution of different loans. Later, they were pegged to specific securitized pools, he noted.
"All that is disclosed," said DeMarco.
