MFI data collection

The Bank of Finland collects statistical data on credit institutions. The RATI survey covers required data for the following: ECB’s and national balance sheet and interest rate statistics, balance of payments and financial accounts statistics, and the Bank for International Settlement’s (BIS) banking statistics.

Under the ECB regulation, the data can also be used for other-than-statistical purposes. Balance sheet data are also used to calculate credit institutions’ reserve requirements. The Financial Supervisory Authority (FIN-FSA) has the right to use the statistical data for supervisory purposes.


MFI data collection (RATI)

All credit institutions are obliged to provide statistical data to the Bank of Finland. Small credit institutions can be granted derogations. Such credit institutions are required to submit statistical data on a quarterly basis.
