Hrvatska poštanska banka was established in October 1991 in the ownership of the Croatian Post. In 29 years of business, the ownership structure has changed, always within state ownership, with ups and downs, but with time the Bank remained the only Croatian-owned bank with a market share of more than 1 percent.
In 2015, the Bank was recapitalized by predominantly private shareholders. The reorganization was carried out in parallel, resulting in the two most profitable years since the establishment of the Bank, along with a strong growth in market shares and several awards from the field of digital banking.
During 2019 Hrvatska poštanska banka completed the merger of Jadranska banka and of HPB-Stambena štedionica.
