Information on reporting

Obtaining survey documents

The SNB informs the reporting institutions in writing about which survey documents are needed. Please use the release as indicated in the letter, i.e. the published release relevant for the reference date for which you are reporting.

You will find the survey documents on the relevant page of the survey. Here you will find survey documents for data deliveries and pdf files with notes and additional information. The survey documents are packaged in ZIP files containing all the documents relating to a particular survey. We recommend downloading the ZIP files and then extracting to a folder. This ensures that any links between Excel files continue to work.

If you only require one document, this can be downloaded from the subpage on the survey in question.

If you are unable to download the documents, the requisite survey documents can be ordered by e-mail at

Reporting institutions registered in eSurvey can also download the survey documents there.

Technical rules on transmission methods for statistical data

Reporting institutions are called upon by the SNB to take part in surveys and are required to provide information using one of the methods prescribed by the SNB. These technical rules set out the details with regard to the methods by which statistical data are to be reported, in particular as concerns their transmission by e-mail. The rules are aimed at making reporting as easy and efficient as possible, while also ensuring the confidentiality, authenticity (origin) and integrity (immutability) of the reported data.

Submission via eSurvey (online reporting system)

Reporting institutions have the possibility of submitting their data to the Swiss National Bank (SNB) via eSurvey, the SNB’s online reporting system. The range of surveys that can be submitted using eSurvey is continuously expanding. Reporting institutions will be informed when surveys in which they participate can be submitted via eSurvey.

Institutions which have already received access details can log in to eSurvey by means of the following link:

Data security

The transmission of data takes place via a secure channel (https). SSL encryption ensures that the recipient is the SNB and that submissions cannot be intercepted by third parties. In addition, reporting institutions are no longer responsible for the installation and periodic updating of security certificates necessary for e-mail encryption.


eSurvey contains a range of functions to support reporting companies when submitting their statistical data:

  • Overview of submissions due
    eSurvey offers users an overview of submissions that are due with the corresponding deadlines, as well as each submission’s status (e.g. outstanding, overdue).
  • Upload and download
    For each outstanding survey, eSurvey users can download the current version of the corresponding survey forms. Uploading xls, xlsx and xml files is easy and secure, and confidentiality is guaranteed.
  • User administration
    Companies can manage access to eSurvey themselves by creating their own users and administering the responsibilities for the submission of individual surveys.
    Companies must make use of the user administration system if they wish to use eSurvey for transmitting statistical banking data.
  • Viewing contact details:
    In eSurvey, users can view their own contact details in the system.  Reporting institutions ensure that their details are constantly kept up-to-date.

Survey material also available on surveys webpage

The survey documents on eSurvey are identical to those found on the SNB website. These are electronic forms in Excel format. Depending on the survey, there may be additional documentation on the SNB website.

Submission by e-mail

All reports delivered to the SNB via e-mail must be sent to Excel files or XML files should be delivered as an attachment in an encrypted e-mail. To ensure that the e-mail can be processed automatically, the structure of the e-mail must be maintained. Further information on this can be found here (pdf).

Faulty deliveries/repeat deliveries

Data deliveries that are incomplete, that cannot be processed for technical reasons, that do not comply with the specifications or that contain validation errors are deemed to be faulty. In such cases, a repeat delivery may be required. Repeat deliveries – i.e. corrected deliveries – must be designated as such and must contain the entire survey.

Submission deadlines and reminder procedures

If the deadline falls on a Saturday, Sunday or a public holiday recognised under federal law or by the canton of Zurich, it will be postponed until the following working day.

If a submission deadline for a survey is not complied with, the reporting institution will receive a reminder. In the event that it fails to report, penalties are provided for by law.

It may transmit data to the appropriate offices (art. 14 para. 2 and art.16, para 4 NBA). If the duty to provide information is breached, the SNB will file a complaint with the Federal Department of Finance (art. 22 para. 3 NBA), which may result in a penalty according to art. 24 NBA.
