Why Bank Size Matters

When researching the largest banks in the US, size often indicates stability and a wide range of services.

• Lower Fees: Online banks often have fewer overhead costs, passing savings to customers.
• Higher Interest Rates: Ally’s savings accounts, for example, often outpace the rates offered by traditional giants.
• Personalized Service: Regional banks like Fifth Third may offer more tailored customer support compared to national behemoths.
