How Online Banks Can Drive Customer Growth in Uncertain Times

‍Turning Uncertainty into Opportunity

‍

Retail and business banking in Germany isn’t what it used to be. Changing consumer expectations, rising international competition, and economic uncertainty have made customer acquisition more difficult—and retention even tougher. While many players are struggling, others continue to grow, capturing market share and deepening customer relationships.

‍

What works nowadays is not just bigger marketing budgets. Growing banks use sustainability for customer growth and loyalty - not as a PR move, but as a powerful business strategy.

‍

"Sustainability is no longer just a ‘trend’ – it’s a standard consideration influencing consumer behavior."

“Our global 2024 study confirms this, with 71% of consumers viewing sustainability as equally crucial as last year. This growing interest in sustainability, the willingness to pay for green alternatives, and the proactive approach to verifying businesses’ claims indicate an urgent need for businesses to understand changing consumer sustainability perceptions.” Simon-Kucher, Sustainability Study 2024

Winning Customers Through Sustainability

‍

The old approach—meeting regulatory requirements and making occasional donations—is no longer enough. Growing banks do things differently. They make sustainability a core part of their brand and use sustainability in marketing to attract eco-conscious consumers.

‍

Here’s how this works:

✅ Beyond Greenwashing
Simply mentioning sustainability on a website or offering donation options isn’t enough. The most successful banks create entire brand experiences around sustainability—experiences customers can feel, engage with, and participate in.

✅ Turning Purpose into Profit
Sustainability is no longer a cost center—it’s a revenue driver. Forward-thinking players integrate high-impact initiatives directly into the customer journey, from tree planting to plastic collection to coral reef restoration. The result? Higher revenue, stronger loyalty, and increased customer engagement.

✅ From Claims to Proof
The era of vague sustainability statements is over. Banks seeing real growth today track, measure, and showcase their impact—right down to the last kilogram of plastic collected or tree planted. And customers? They love it.

‍

This shift isn’t just good for the planet—it’s transforming how customers connect with brands.
