Deep Dive of the Week


How Bank of America Built a $40B Consumer Banking Machine

Bank of America’s consumer banking division is a massive, integrated machine that produces over $41 billion in annual revenue and $10.8 billion in net profit as of 2024, accounting for roughly 37% of the bank’s revenue. This operation spans everything from basic checking accounts and credit cards to digital platforms and wealth management tie-ins. What follows is a first-principles breakdown of how BofA’s consumer banking model works end-to-end, from gathering deposits and making loans to the technology stack, loyalty mechanics, and distribution strategy that bind it all together. We’ll also compare Bank of America’s approach to peers like JPMorgan Chase and Citibank, and tease out hidden fragilities and lessons for fintech operators and banking strategists.

Most banks think they are doing personalisation. Customers strongly disagree.

I have been digging into recent research from Quinlan & Associates and Synpulse, and the data makes one thing very clear. The personalisation is measurable, widening, and expensive.

✅ Start with expectations.

Around 74 percent of retail banking customers say personalisation is important or critical to their banking experience. Yet only 44 percent say they have actually experienced any form of personalised service. And even among those, 52 percent say they were not satisfied with what they received.

That means more than 70 percent of customers who care about personalisation either never experienced it or were disappointed when they did.

✅ This is not because banks lack data.

Most banks already hold years of transaction history, life-stage signals, product usage data, and behavioural patterns. Despite that, customer journeys are still largely generic. Marketing campaigns remain broad. Emails and push notifications ignore past behaviour. Product onboarding is rigid. Post-sale engagement barely changes whether someone has been a customer for six months or six years.

The result is that every bank sounds the same and treats customers the same, regardless of context.

Digital banks have made progress, but even there, the ceiling is low. Many offer surface-level personalisation like tailored dashboards or basic insights. Truly embedded personalisation, where products, pricing, advice, and support dynamically adapt to the customer’s situation, is still rare.

And the consequences show up in loyalty.
