Bank PBKS was one of nine banks spun off in the late 1980s from the
National Bank of Poland, the culmination of a sequence of reforms during the 1980s that brought an end to the country's
single-tier banking system. On , Bank PBKS was transformed into a
joint-stock company, fully owned by the Polish State Treasury. By the mid-1990s it was one of the two smallest of the nine regional banks separated from the NBP, together with
Bank Depozytowo-Kredytowy (Bank BDK) in
Lublin. In 1996, a government decision brought together
Polska Kasa Opieki with Bank PBKS and two of its peers established in 1989, Bank BDK and the much larger
Bank PBG in
Łódź. On , the four banks were merged into Bank Polska Kasa Opieki SA, or
Bank Pekao. ==See also==
