Counterparties have various options for connecting to the Deutsche Bundesbank's collateral management system. The specialized procedure CAP (Collateral Management Access Portal), which can be accessed via ExtraNet, offers U2A (user-to-application) access to various collateral management functionalities. You can use it to query the collateral pools for BBk own-account transactions or for deposit protection purposes. You can receive important notifications relating to these collateral pools in paperless form in your ExtraNet mailbox. In addition, two A2A (application-to-application) connections are available to you via SWIFT and XML, which enable automated communication with the Deutsche Bundesbank system.
