countries, and in a second step, the national BLS results are aggregated to euro area BLS results.
In the first step, banks’ replies can either be aggregated to national results by applying an
implicit weighting through the sample selection or, alternatively, banks’ replies can be
aggregated by applying an explicit weighting scheme based on the amounts outstanding of loans
to non-financial corporations and households of the individual banks in the respective national
samples. In the second step, since the number of banks in the national samples differs
considerably and does not always reflect the respective share in lending to euro area nonfinancial corporations and households, the national survey results are aggregated to euro area
BLS results by applying an explicit weighting scheme based on the national shares in the
amounts outstanding of loans to euro area non-financial corporations and households.
The option to aggregate individual bank results to national BLS results based on an explicit
weighting scheme was introduced in the April 2014 BLS survey round and led to some
revisions (including backward revisions) of the BLS results for France, Malta and Slovakia (the
three countries currently applying an explicit weighting scheme) and, in consequence, to overall
small revisions (including backward revisions) of the euro area BLS results.
Detailed tables and charts on the responses are provided in Annex 1 for the individual questions
and in Annex 2 for the ad hoc questions.
