AUC/A figures for individual banks are taken from their quarterly earnings releases. While BNY Mellon reports only total AUC/A figures as a part of its quarterly earnings, JPMorgan and Citigroup exclude assets under administration from their reporting – providing only AUC numbers. State Street details its AUC/A as well as AUC figures at the end of each quarter. Notably, the four largest custody banks are all based in the U.S., and are responsible for nearly half the industry. While BNY Mellon and State Street are primarily focused on custody banking services to make money (with these services contributing 45-50% of their values, according to our estimates), JPMorgan and Citigroup have extremely diversified business models, with custody banking services being responsible for less than 5% of their valuation.
