Československá obchodní banka, a.s. (ČSOB) is one of the largest commercial banks operating in the Czech Republic.

[3] ČSOB was established in 1964 in the former Czechoslovakia as the sole bank providing foreign trade, financing and convertible currency operations.

[5] Prior to acquiring its bankrupt competitor Investiční a poštovní banka in 1999, ČSOB was the fourth-largest bank in the Czech Republic.

The acquisition of Investiční a poštovní banka, at the time the third-largest Czech bank, brought an additional 3.3 million customers and a network of 179 branches.

[13] In 2019 ČSOB bought the remaining 45% of Českomoravská stavební spořitelna (ČMSS) from Bausparkasse Schwäbisch Hall (BSH) for 6.15 billion crowns.

ČSOB withheld the funds due to their unclear origins as the listed address of the headquarters of TEP Praha were leading to a run-down building that was auctioned off earlier in 2020 and because the company was not active in the years before the lawsuit.
