Bank 3.0 by Brett King: Why Banking Left the Building
Book: Bank 3.0: Why Banking Is No Longer Somewhere You Go But Something You Do Author: Brett King ISBN: 978-1-118-58963-2 Publisher: Wiley (2013)
So I picked up this book called Bank 3.0 by Brett King. It was written in 2013. And honestly, reading it now feels a bit like finding someone’s predictions about the future and realizing they got most of it right.
The subtitle says it all: “Why Banking Is No Longer Somewhere You Go But Something You Do.”
Back in 2013, that was a bold claim. Most people still walked into bank branches to open accounts. Mobile banking apps were clunky. And the idea that you’d manage your entire financial life from your phone felt like something out of a tech demo, not real life.
But here we are.
Why This Book, Why Now
I’m starting this series because Bank 3.0 is one of those books that saw what was coming before most people in the industry did. Brett King wasn’t just guessing. He was connecting real dots.
The book is actually an updated version of his earlier Bank 2.0. He wrote that one before the financial crisis fully played out. By the time Bank 3.0 came around, the crisis had already exposed how disconnected traditional banks were from regular people.
And that disconnect created an opening.
PayPal started handling payments better than most banks could. Square gave every small business a card reader. Simple (remember Simple?) tried to build a bank that actually made sense to use. These weren’t banks. They were tech companies that happened to do banking things.
King saw all of this happening and asked a simple question: if these companies can do banking better than banks, what happens to banks?
What the Book Covers
Bank 3.0 has 14 chapters split into three parts:
Part 1: Changes in Customer Behaviour (Chapters 1-2) How consumers changed. What they expect now. Why the old model of “come to our branch and wait in line” stopped working.
Part 2: Rebuilding the Bank (Chapters 3-8) The practical stuff. How banks need to rethink branches, the web, mobile, social media, and their whole approach to customers.
Part 3: The Road Ahead (Chapters 9-14) Where things are going. New payment systems, the death of cash, regulation, and what banking looks like when it’s built around the customer instead of the branch.
The “De-Banked” Generation
One of the most interesting ideas in the book is what King calls the “de-banked.” These are people who just stopped using traditional banks altogether.
Not because they couldn’t afford bank accounts. But because they found better options.
Prepaid debit cards. PayPal accounts. Mobile payment services. In 2011, the US alone had over $200 billion loaded onto prepaid debit cards. That’s a lot of money flowing outside the traditional banking system.
King saw this as a warning sign. People weren’t leaving banks because they hated them. They were leaving because banks weren’t keeping up.
Bill Gates once said something that King quotes in the book: “Banking is necessary, banks are not.” That line pretty much sums up the whole argument.
Why It Still Matters
Look, some parts of the book are obviously dated. King talks about technologies and companies that either evolved into something else or disappeared entirely. That’s what happens with any book about technology.
But the core ideas held up. Banking did become mobile. Branches did shrink. Fintech companies did force traditional banks to actually think about their customers.
The predictions about mobile payments, about banking becoming invisible and just part of your daily routine, about customers expecting the same experience from their bank as they get from Amazon or Google. All of that happened.
And some of it is still happening. We’re still in the middle of the shift King was writing about.
How This Series Will Work
I’m going to go through the book chapter by chapter. Each post will cover what King argued, what he got right, what he missed, and what still applies today.
This isn’t a summary. It’s more like a conversation with the book. I’ll pull out the ideas that matter and skip the parts that don’t hold up anymore.
If you work in banking, fintech, or just want to understand how your phone became your bank, this series should be useful.
Let’s get into it.
