Like the car industry, the bank credit card industry is coming down to three major players, namely Chase, Citi, and BofA. The recently announced merger of Bank of America and MBNA will raise the U.S. market share of the top three general purpose credit card issuers from 49% to 58%, based on card loans. Based on gross dollar volume charged, the share of the big three will approach 70% or more. Basically, each of the top three issuers will have at least $100 billion in credit card outstandings and $300 billion in annual gross dollar volume. The next largest issuer, Discover, has about $50 billion in credit card loans and $100 billion in annual charge volume.
