Nahum Zeev Williams purchased Bank Ha'olim in 1938 and on his death the bank passed into the hands of a group headed by his family, associated with the Mizrachi movement.
By 1961 it had branches in Tel Aviv, Jerusalem, Haifa, Netanya, Jaffa, and London.
In July 1974 the bank collapsed, owing British investors £46.6 million.
[2][3][4] Although the Israel-British Bank was headquartered in the United Kingdom, the majority of its stockholders were Israeli.
Still, in mid-1975 the Israeli government agreed to permit the pooling of the London subsidiary's remaining assets with those of the parent to satisfy creditors.
