The title of the number one bank in the world depends heavily on whether institutions are evaluated by total assets or market capitalization. When measured by total assets, the Industrial and Commercial Bank of China (ICBC) holds the top spot globally, managing multi-trillion-dollar portfolios backed by the massive Chinese commercial economy. Conversely, when evaluated by market capitalization—reflecting total public equity value and investor valuation—American financial giant JPMorgan Chase consistently ranks as the largest bank in the world.
