The Electronic Secondary Securities Market (HDAT) is the regulated market (initial Government Gazette, Β 998/27.05.09) for Greek government securities and bonds or other fixed-income debt securities issued by corporations and other entities with the guarantee of the Greek government.
HDAT is operated and managed by the Bank of Greece. Its operation, organisation and management are regulated by Operating rules. HDAT is a quote-driven market where assets are traded at “bid” and “ask” prices quoted by participants/dealers. The HDAT technical platform is also used for auctioning Greek Government securities in the primary market and for end-of-day buy/sell back transactions in securities within the Book-Entry Securities System of the Bank of Greece (BOGS). HDAT has a real-time data service connection with Bloomberg and Refinitiv.
As from 15 March 1999, HDAT issues the official daily price bulletin for government securities under Law 2651/98.
