Financial and technological innovation and changes in the macroeconomic environment have led to the growth of nonbank financial institutions (NBFIs), and to the possible displacement of banks in the provision of traditional financial intermediation services (deposit taking, loan making, and facilitation of payments). In this post, we look at the joint evolution of banks—referred to as depository institutions from here on—and nonbanks inside the organizational structure of bank holding companies (BHCs). Using a unique database of the organizational structure of all BHCs ever in existence since the 1970s, we document the evolution of NBFI activities within BHCs. Our evidence suggests that there exist important conglomeration synergies to having both banks and NBFIs under the same organizational umbrella.
