Lists of the top banks in the world will come up with differing names, depending on whether you use assets, revenue, market capitalization, size of customer base or any one of the many other reference points that can measure the relative sizes to grade them. As a result, these usually come up with different results. As well, some banks use reporting methods that have to conform with their own countries’ regulations and so use a different basis for reporting.
To rank the top 50 banks in the world by market cap will give the most reliable answer, because this is a public and real measure, but it will leave out operating banks that are not themselves quoted on a stock exchange, but are wholly-owned subsidiaries either of a parent financial institution or of a private entity.
Of the 50 top banks in the world by market capitalization, 11 are located in the USA, headed by JPMorgan Chase, which is the largest bank in the world in this ranking.
Next in the list is mainland China with 9 banks, headed by Industrial & Commercial Bank, which is number two on the global list.
