Economies of scope in financial intermediation continue as a focal point in strategic and regulatory debates. In this paper, we summarize the theoretical research on the value of diversification in financial services firms, and survey the empirical research so far on the conglomerate discount in US and international financial services businesses. We also review research on the internal capital market efficiency in universal banks and financial conglomerates. The paper provides new empirical evidence on the conglomerate discount in US financial intermediaries and how that changes between non-crisis and crisis periods, showing a decline in the discount under turbulent conditions.
