After World War II, the bank's Berlin seat found itself in the Soviet occupation zone, but the bank was able to maintain legal continuity through a Thuringian office it had created in 1943, which was relocated to Erlangen in 1945 and eventually to Frankfurt in 1948, then allowed by special legislation in 1954 o assume the full BHG legacy.

Following German reunification, the former BHG building was repurposed to become the Berlin office of KfW, on a design by Frankfurt-based ABB Architects.
