Disruption doesn’t announce itself. It accumulates in the background — in the small frustrations, the workarounds, the things customers learn to tolerate — until one day an alternative shows up and the tolerance evaporates.

That’s the story of European retail banking over the past twenty years, and it’s worth telling properly because the people living through it often can’t see the pattern until it’s behind them.

Start with what the traditional banks were actually doing. Since the early 2000s, they’ve been occupied with three enormous projects, all running simultaneously. First, the regulatory avalanche: the Euro introduction, SEPA rollout, prudential supervision under Basel III, AML directive after AML directive, GDPR, MiFID. Each one a multi-year programme. Each one mandatory. None of them customer-facing in any way that customers would notice or appreciate.

Second, digitalisation — and I use the word with some hesitation, because what most banks actually did was digitise existing processes rather than rethink them. They took paper forms and put them on screens. They took branch workflows and replicated them in apps. The underlying architecture remained what it was in the 90s: COBOL on mainframes, siloed systems that don’t talk to each other without middleware that nobody wants to touch. If you’re a computer science graduate under 30, this is not the environment that makes you jump out of bed in the morning.

Third, the cultural shift to “customer centricity.” Around 2010, every consultancy in Europe was selling some version of outside-in thinking. The idea was sound — start with what the customer needs, work backwards to the product. But for a retail bank carrying thirty years of regulatory infrastructure and organisational complexity, customer centricity was the hardest transformation of the three. You can’t just decide to be customer-centric. You have to become it, and that means changing incentive structures, decision-making processes, and the fundamental question your product teams ask every morning.

Now look at what walked through the door while the incumbents were busy with all of that.

N26 launched in Germany with a proposition that was, at its core, disrespectful to the established order. Their #nobullshit campaign in 2018 declared “Bank Branches are soooooo 90’s” — and in the German market, where the Sparkassen network is practically a civic institution, that was a genuinely provocative thing to say. By 2019, they’d exceeded one million customers in France, making it a top priority market. Revolut, TransferWise (now Wise), Bunq — each one scratching a different itch that the incumbents had been too busy to notice.

The neobank advantages aren’t mysterious. They carry just enough regulatory burden — most got their licences when their businesses were already well established, so compliance scales alongside revenue rather than preceding it. They’re born digital, which doesn’t just mean they have apps. It means they don’t have non-digital workflows. There’s no branch process to digitise because there was never a branch. And customer centricity isn’t a transformation programme for them — it’s the founding premise. They scratch the itch first, then figure out the compliance and operations around it.

This is the classic disruption pattern. The incumbents aren’t stupid or lazy. They’re occupied. They’re dealing with genuinely important things — regulatory obligations, infrastructure modernisation, risk management. But while they’re occupied, someone else notices that the customer hasn’t been asked what they actually want in years.

The interesting question isn’t whether disruption is happening — it clearly is. The interesting question is what happens next. The neobanks are starting to feel the weight of the same regulatory machinery that slowed the incumbents. N26 had to build actual branches in multiple markets to offer local IBANs — the very thing their marketing said was obsolete. Revolut’s journey to a full banking licence has been a multi-year education in why banks are the way they are.

The revolution is real. But revolutions have a habit of creating new establishments that look surprisingly like the old ones. The question is whether this generation of challengers can hold onto what made them different while absorbing the complexity that comes with scale.
