The largest US banks hold trillions of dollars in loans, securities, cash and other assets, but the ranking depends on the entity being measured. A bank holding company can include investment banking, markets, wealth management and other subsidiaries beyond the consumer bank most customers recognise.

American Commerce Review uses Federal Reserve and FDIC data as the starting point, then looks at the business mix behind the balance sheet. Assets are useful for scale, not for deciding which bank is strongest or most profitable.

JPMorgan sits at the top of the system

JPMorgan Chase combines one of America's largest deposit franchises with corporate banking, markets, asset management, credit cards and investment banking. That diversification helps explain why its consolidated balance sheet is much larger than a simple branch-network comparison would suggest.

Bank of America also combines a major consumer franchise with wealth management and corporate banking, while Citigroup's international and institutional operations create a different asset mix.

Assets and deposits answer different questions

A bank can hold large trading assets and securities without having the largest domestic deposit base. Conversely, a retail-heavy institution may rank very highly by deposits while sitting lower by consolidated assets.

For consumers, deposits and branches may be the more intuitive measures. For financial stability and capital analysis, consolidated assets are more informative.

The ranking changes through mergers and balance-sheet growth

Bank acquisitions, loan growth, securities portfolios and changes in market activity can alter the order over time. The most useful evergreen approach is therefore to maintain the methodology and refresh the underlying figures rather than present a permanent fixed number.
