The global financial crisis, and the ensuing Dodd-Frank Act, identified size and complexity as determinants of banks’ systemic importance, increasing the potential risks to financial stability. While it’s known that big banks haven’t shrunk, the question that remains is: have they simplified? In this post, we show that while the largest U.S. bank holding companies (BHCs) have somewhat simplified their organizational structures, they remain very complex. The industries spanned by entities within the BHCs have shifted more than they have declined, and the countries in which some large BHCs have entities still include numerous “secrecy” or tax-haven locations.
