Following the complete nationalization and reorganization of the banking sector in 1948, the Postal Savings Bank was abolished and its assets (including its iconic building) taken over by the
Hungarian National Bank (MNB). The distribution of rudimentary savings services through the post office network was entrusted to the Hungarian National Savings Bank Company (), one of the country's four main financial institutions alongside the MNB, the Hungarian Investment Bank (renamed the State Bank for Development in 1972 and liquidated in 1987), and the
Hungarian Foreign Trade Bank. A successor entity named Postabank was established in 1988 to offer financial services through the Hungarian post office network, majority-owned by
Magyar Posta with a 20-percent stake sold to foreign investors in 1990. It grew rapidly until 1996, then experienced severe deposit withdrawal in 1997 and had to be bailed out by the government in 1998. It was sold to
Erste Group in 2003. ==See also==
