Differentiate between a “Title Transfer” CSA and a “Security Interest” CSA.
A Title Transfer CSA legally transfers the ownership (title) of the collateral from the pledgor to the secured party. The secured party can then re-use (rehypothecate) the collateral.
A Security Interest CSA does not transfer title; the pledgor retains ownership, and the secured party receives a security interest (lien) over the collateral, which limits the secured party's ability to re-use it.
