Bank of America is a formidable financial titan with a $3.5 trillion balance sheet and a cornerstone of the American economy, holding the second-largest deposit market share in the United States. While the firm has maintained its stronghold among middle-market and retail clientele domestically, Bank of America has continued to hold its own on the global stage, as evidenced by its fourth-largest global trading operation and an investment banking division that regularly finishes in the top four in global league tables. The firm is organized across four segments: consumer banking, global wealth and investment management, global banking, and global markets.

Citigroup is a global financial powerhouse that orchestrates the movement of $5 trillion in daily transaction volume, serving as the essential connective tissue for the world's most complex multinational corporations. The firm remains a leader on the global stage, servicing 90% of the Fortune 500 through a proprietary network that includes direct membership to over 270 cash-clearing centers and a footprint that spans 94 countries. After a checkered history operating as an overly complex, disjointed firm, steps have been taken to streamline operations, resulting in organization across five segments: services, markets, banking, wealth, and US personal banking.
