The differential treatment of large financial institutions has drawn substantial interest in recent financial regulatory discussions. In particular, several regulatory measures put in place after the 2008 financial crisis have singled out large banks as subjects of increased regulatory scrutiny. At the same time, the U.S. banking industry has experienced a secular increase in concentration: The total number of U.S. banks has dropped from 25,000 in the 1920’s, to 14,000 in the 1970’s, to less than 6,000 as of today, while the top 10 bank holding companies now control more than 50% of total bank assets. These developments suggest that concerns about too-big-to-fail banks are now more important than ever before.
