The collection of the data required to draw up the balance of payments does not follow a standardised procedure, but instead is organised pragmatically in Germany as a modular system. External sector reporting is the core component, which as a general rule requires all resident banks, enterprises, households and public authorities participating in external transactions to report their transactions with non-residents. The legal basis is provided by section 11 (2) of the Foreign Trade and Payments Act (Außenwirtschaftsgesetz) together with section 67 et seq of the Foreign Trade and Payments Regulation (Außenwirtschaftsverordnung).
Data from other sources are used as supplementary components, the most significant of which are
- Foreign trade statistics from the Federal Statistics Office
- Household survey on travel expenses abroad
- External position of banks and non-banks and foreign direct investment stock statistics
- Deutsche Bundesbank’s internal accounting
- Other national and international statistics for reconciliation and as a basis for estimates
