Are 2% Cash Back Cards Still King? a Deep Dive into 2026 Credit Card Offers

Uncover everything you need to know concerning Are 2% Cash Back Cards Still King? a Deep Dive into 2026 Credit Card Offers.

There is a major exception to the classic 2% ceiling, and it sits within institutional relationship banking. As Yahoo Finance noted in its 2026 coverage of premier banking networks, the Bank of America Preferred Rewards program fundamentally changes earning calculations for consumers who maintain investment or cash balances with the institution.

Cardholders who maintain qualifying deposits across Merrill investment accounts and Bank of America balances unlock graduated rewards tiers:

• Gold Tier ($20,000 to $49,999): Earns a 25% reward bonus, lifting a baseline 1.5% card to 1.87% cash back.
• Platinum Tier ($50,000 to $99,999): Delivers a 50% reward bonus, raising that baseline card to 2.25% cash back.
• Platinum Honors Tier ($100,000+): Unlocks a 75% reward bonus. The Bank of America Customized Cash Rewards jumps to 5.25% on chosen categories, while the Unlimited Cash Rewards card earns an uncapped 2.625% flat back on every single purchase.

For high-net-worth consumers seeking a zero-maintenance setup, this 2.625% flat-rate return completely sidelines standard 2% cards without forcing users into the point transfer ecosystem.
