Source of information for determining percentage of market share of Payment services to non-MFIs split into segments (RESOL2 - Template Z 07.01.3 FUNC 1 PAY)

Where can we find source of information for determining percentage of market share of Payment services to non-MFIs split into segments (consumers, non-consumers - SME, and non-consumers - non-SME)?

In template  Z 07.01.3 it is necessary to provide market shares of banks in credit transfers by client segments (consumers, non-consumers - SME, and non-consumers - non-SME). In the available CNB statistics, payment transaction data are presented according to the division into consumers and non-consumers, while the resolution requirements imply a more detailed segmentation of non-consumers into SME and non-SME. We kindly request information on whether statistics or internally aggregated data on credit transfers by the specified client segments are available at the CNB level, or recommendations on how an acceptable regulatory estimate of market shares can be made for the purposes of resolution reporting. We have checked with colleagues from the payment transactions department in CNB and there is no more detailed aggregated segmentation of non-consumers into SME and non-SME, neither with us nor at the ECB.
