Largest Banks by Market Cap in 2025

Market capitalization (market cap) is the total value of a company's outstanding shares of stock. For banks, it reflects investor sentiment, financial health, and growth expectations. It’s a key metric used by institutional investors to benchmark performance, assess size and stability, and identify potential investment opportunities within the global banking sector.

This list includes publicly traded commercial and investment banks across global markets, ranked by their total market capitalization as of 2025. It does not include private banks, central banks, or non-banking financial companies (NBFCs) unless they are publicly listed and primarily operate as banking entities.

Market cap changes each time the value of a stock changes, which means static lists of market cap rankings are generally unreliable. That’s why our market capitalization rankings are pulled directly from the AlphaSense platform and update dynamically in real-time — giving you the most accurate and up-to-date picture of the banking industry.

Banks’ market capitalization is influenced by several factors, including interest rate trends, earnings performance, regulatory policy, capital adequacy, net interest margins, asset quality, and investor sentiment. Macroeconomic trends and geopolitical events also play a significant role in valuation.
