This dataset provides a sectoral breakdown of all securities issuances of equity or debt by Irish resident entities. Data is published on a monthly basis and shows the trends in total issuance (stock) and transactions (flow). From December 2020, the Securities Issues data is published using data obtained via the ECBs Centralised Securities Database (CSDB). The CSDB Securities Issues Statistics (CSEC) is a harmonised approach that covers all 27 EU Member States and follows international standards for aggregated statistics found here. This is an advancement from the previous SIS process where aggregates were compiled nationally and submitted to the ECB through each National Central Bank. The compilation of each series in the CSEC uses a bottom-up approach and is aggregated from the most granular ISIN level data. A factsheet on the CSEC data can be accessed via this link: https://www.ecb.europa.eu/stats/financial_markets_and_interest_rates/securities/shared/pdf/CSEC_Factsheet.sv.pdf
