What is a megabank?

Written by Editorial Team | Last Updated: August 2026

A megabank is an informal financial industry term used to describe massive, multinational commercial and investment banking institutions that possess global scale, enormous balance sheets, trillions of dollars in assets, and extensive branch or digital networks spanning multiple continents. Prominent global examples include JPMorgan Chase, Bank of America, Citigroup, and HSBC. These institutions operate as universal banks, offering comprehensive financial services ranging from retail checking accounts and mortgages to complex corporate underwriting, global wealth management, and institutional trading. Because of their systemic importance to the global economy, megabanks are subjected to stringent international regulatory oversight, capital reserve mandates, and regular stress tests.
