IBIS (Historical Balance Sheet Data) is an IT procedure that combines in a single environment the accounting data currently available in various Bank of Italy publications, facilitating their retrieval and increasing their usability.
In particular, IBIS makes available data drawn from the Bank's annual accounts from 1894 to the present day and, since 1999, the historical series of monthly financial statements. Since 1999, the year in which the European System of Central Banks (ESCB) was launched, the balance sheet and profit and loss account data, supplemented by detailed information, have been processed in accordance with the formats and presentation methods currently in force in order to provide a historical data series that is homogeneous and comparable over time. Again, since 1999, a historical data series drawn from the notes to the accounts and from the management reports has also been available.
The data can be exported in Excel and PDF formats and, for some sections, average data and average and precise incidence ratios can be calculated. In sections where the formats are not homogeneous over time, the calculation of average data and incidence ratios is only possible within the periods in which the data reporting formats remain unchanged.
