This menu item contains the most important information for registering with and using MACCs. All the files mentioned in the text can be downloaded from the thematic list at the bottom of the page.
Information for new customers
It is necessary to have a collateral account at the Deutsche Bundesbank to be able to use MACCs.
If such an account has already been set up, there are only a few steps that need to be taken to be able to submit credit claims using the MACCs application:
- the completed contact form needs to be sent by fax or email to the support team credit claims;
- all required participation documents must be signed with a legally binding signature and submitted by post;
- the mandatory customer test needs to be carried out following registration in the MACCs test environment;
- the MACCs users need to be registered in the Deutsche Bundesbank’s ExtraNet;
- the registration needs to be approved by the Deutsche Bundesbank.
Further information on registering for ExtraNet can be found under the menu item “User management”.
The ExtraNet is the Deutsche Bundesbank’s e-business-platform. Each counterparty wishing to use MACCs must first register users with the relevant roles in ExtraNet. The link provided at the bottom of the page can be used for this purpose. The application form, once signed with a legally binding signature, can be submitted as an original document by post or scanned and sent as a PDF file via email to firstname.lastname@example.org.
As a general rule, the initial registration of a future MACCs user must be made using the link below. However, this initial registration is not required if the user is already registered for the IT applications OMTOS, BBS, EBS or CAP in ExtraNet. In these cases, a secondary registration is possible via the link below.
Please note that the Special Terms and Conditions for submitting credit claims as collateral (MACCs Terms and Conditions) expressly prohibit the changing of the first and last names of a user to transfer a user ID, even though this is technically possible in ExtraNet and the procedure is also described in the ExtraNet terms and conditions. The same applies to the use of a functional user, which can technically be set up in ExtraNet.
All counterparties have two options for submitting credit claims: the online procedure and the file-transfer procedure. There is also a backup procedure for both types of submission.
The online procedure can be carried out via the Deutsche Bundesbank’s ExtraNet and requires a MACCs login as a first step. Counterparties can submit credit claims and retrieve reports in the MACCs application. A distinction is generally made between the submission of debtor data and credit claims data. Counterparties that have selected their own IRB rating system as the credit assessment procedure must also record the IRB rating of the respective debtors in MACCs before they can submit credit claims from these debtors. The system only allows the submission of debtor data for first-time entries, which is why changes to debtor data, such as changes in the address or a change of legal form, must be sent by email to email@example.com immediately after they become known.
The submission of credit claims is broken down by business type: new submission, update and voluntary return. In order to minimise the frequency of errors, the principle of dual control is generally applicable for entries in MACCs. The evaluation functions provide counterparties with extensive information on current and historical submissions and stocks of credit claims (for information on the use of historical data from KEV, see the relevant section entitled “Current issues and circulars”). In addition, counterparties can access written confirmations, the evaluation list and the debtor search function under the “Evaluations” menu item.
More information on the online procedure can be found in the MACCs documentation.
File transfer procedure
Like the online procedure, the file transfer procedure takes place via the Deutsche Bundesbank’s ExtraNet. The procedure for the submission (upload) and receipt (download) of files is described in detail in the MACCs documentation. The file transfer procedure is particularly useful for submitters who wish to assign a large number of credit claims to the Deutsche Bundesbank. The procedure for transferring a large number of data records for submissions, updates and returns of credit claims in a single file is largely automated, but requires the submitter to have appropriately programmed implementation routines in place in order to create the files to be transferred to the Deutsche Bundesbank and to ensure that the receipt and stock files received by the Deutsche Bundesbank are readable.
Counterparties need to apply for the file transfer procedure separately. For this purpose, Deutsche Bundesbank provides templates for the structure and content of the files.
The templates are described in detail in the “Explanatory notes on the files in the MACCs file transfer procedure”, including a comprehensive description of the plausibility checks implemented for the submission file.
When MACCs was designed, great importance was attached to high availability. In the event that access to MACCs is not possible during operating hours, the backup procedure is generally employed after consultation with the support team credit claims. This allows for the submission, updating and return of credit claims as well as the updating of ratings via email or fax.
More information on the backup procedure can be found in the MACCs documentation.
Should you experience any problems or disruptions in relation to MACCs or accessing ExtraNet, you are advised to contact the support team credit claims immediately. The operating and support hours can be found at the top right-hand side of this page.
The MACCs documentation contains important information on the submission of debtor and rating data as well as on the submission and administration of credit claims. The description of the evaluation function will be updated in a timely manner. If any special documents are required (such as forms for ExtraNet user management), the relevant links are provided.
The MACCs documentation consists of the following:
- general description of the procedure;
- online procedure – user instructions;
- file transfer – user instructions;
- backup procedure – user instructions.
Current issues and circulars
Below we provide a selection of previous customer information letters, guidance notices and other information on the MACCs procedure. Customer information letters relating to KEV will generally retain their validity after the launch of MACCs. Any regulations or procedures that deviate from those listed in the documents are explained, where necessary. Only in German.
Note on accessing data which have not been migrated from KEV
When MACCs was launched, current data required for the operation of the application were initially migrated.
In order to ensure that old KEV data can be used without any difficulties until the final migration of historical data from KEV takes place, counterparties will retain their ExtraNet access to KEV. However, this is restricted to read-only access and can be used for evaluation purposes only.
It is envisaged that the entire KEV data history will be transferred to MACCs by 31 January 2021.
For participation in the MACCs procedure, the following forms are available for download, depending on the type of connection. Partly in German.
