A representative target audience simulation with Minds shows that 74 percent of German savers under the age of 25 cite a guaranteed local reinvestment of their deposits as the main reason for their loyalty to their regional bank. These results were validated against official data from the Statistisches Bundesamt and demonstrate the high relevance of regional sustainability concepts for Gen Z.

This study is based on a highly precise target audience simulation conducted via the Minds infrastructure. Minds is not a generic chatbot, but a specialized platform for professional target audience simulations that enables marketing, insights, and innovation teams to pre-test concepts, campaign claims, and product positionings. This protects valuable budgets and customer trust before physical panels or expensive field trials are even initiated.
The scientific foundation of Minds is based on a three-tier model that guarantees maximum alignment with real market conditions:
Level 01 (Data Anchoring): The foundation is built on real primary data, such as CRM data, internal customer surveys, or traditional market studies. No persona or simulation is based on pure assumptions.
Level 02 (Simulation Model): This is where a robust behavioral model comes into play, linking demographic anchors with in-depth consumer behavior.
Level 03 (Validation): The simulation results are continuously benchmarked against real panel data and established reference standards. This includes data from Kantar, Eurostat, the Statistisches Bundesamt, as well as established demographic and psychographic models.
Through this three-tier calibration, Minds achieves an average match of 85 to 95 percent with traditional physical panels regarding preferences, linguistic nuances, and objection structures. For specific questions and precisely anchored segments, the match can even reach up to 100 percent. Unlike traditional market studies, which often take several weeks, Minds delivers these deep insights in under an hour. Furthermore, the simulation is conducted at a fraction of the cost of a traditional panel and without the usual recruitment costs per participant. The platform is fully hosted on EU servers and operates in 100 percent compliance with GDPR, as no personal data of real participants is processed.
It is explicitly pointed out that Minds is not designed for clinical or regulatory studies, representative price elasticity analyses, or political surveys.
Regional banks, such as Sparkassen and cooperative banks, face a historic challenge: they must win over the next generation of savers to remain viable in the long term. This young target group, Generation Z, is characterized by a strong awareness of ecological and social sustainability. This presents a unique strategic opportunity for regional banks. They can leverage their traditional strength - local roots and the reinvestment of funds within the region - as their strongest argument for customer retention.
However, the simulation shows that global climate protection initiatives alone are no longer enough to secure the loyalty of savers under 25. Gen Z demands a concrete link between global goals and local action. They want to see their savings drive positive change directly on the ground. If a bank cannot provide this proof, they risk losing this valuable customer segment to agile neobanks and fintechs that advertise with transparent, though often less regional, sustainability claims.
I want my savings to fund wind turbines or daycare centers right here in the region, rather than flowing into fossil fuels. If my Sparkasse doesn't show this transparently, I will switch to a neobank.
The results highlight that for the younger generation, sustainability is not an abstract buzzword. It is a concrete decision criterion when choosing a financial partner. Regional banks must therefore learn to actively and digitally communicate their local investments - whether it is the construction of solar parks in the region, the energy-efficient renovation of municipal buildings, or the support of local social projects.
Although Gen Z is considered a digitally native generation that prefers innovative financial apps, their investment behavior reveals a surprising ambivalence. According to current market observations, as also described in studies by zeb or Tink, around 56 percent of young savers still keep their money in traditional savings accounts despite low interest rates. In times of global crisis, the need for security is extremely high. At the same time, the willingness to switch is higher than ever: 58 percent of respondents would switch banks without hesitation if a competitor offered a better digital experience or more convincing ESG features.
This creates a glaring perception gap. While many bank executives believe they understand the needs of the younger generation perfectly, the majority of Gen Z feels left behind by traditional offerings. They demand intuitive, mobile management of their finances that simultaneously makes the ecological impact of their deposits transparent. A simple savings account without digital proof of sustainability no longer meets the demands of this generation.

Security is extremely important to me, which is why I still keep my money in a savings account. But I expect my Volksbank to have an app that shows me exactly how my deposits are protecting the local climate.
The challenge for regional banks is therefore not to develop highly complex, high-risk investment products. Instead, they must digitally upgrade existing, secure forms of investment, such as savings accounts or traditional savings plans. A digital dashboard that shows the user in real time which local sustainability projects are supported by their deposits can make all the difference.
The quantitative simulation investigated how strongly a guaranteed local reinvestment influences the loyalty of young savers. The result is clear: 74 percent of respondents rate this factor as very important or essential to their decision to stay with their regional bank. Local reinvestment beats global climate protection initiatives when both are considered in isolation. However, the highest retention effect is achieved when both worlds merge.
Young savers want to know that their money is not flowing into anonymous, global corporations whose sustainability reports are often difficult to decipher. They prefer tangible projects in their immediate vicinity. This creates an emotional connection to the bank that cannot be achieved through pure yield promises or global marketing campaigns. In this way, regionality transforms from a perceived relic of the past into the most modern differentiator in the competition against neobanks.

Global climate goals are good, but often abstract. If my regional bank guarantees that every euro is reinvested locally and I can track that in real time, I will stay loyal.
For regional banks, this means they must fundamentally rethink their marketing and product strategy. Instead of advertising with abstract carbon offsetting in distant countries, they should focus on concrete projects within the region. The simulation shows that this form of transparent, local value creation is the most effective way to prevent churn among young customers while strengthening trust in the brand.
To successfully translate the insights of this study into practice, regional banks should pursue a three-step strategy:
First: Create digital transparency. The banking app must be expanded to include features that visualize the sustainability impact of deposits. A carbon tracker or an interactive map of regionally funded projects are excellent tools for this.
Second: Target-group-specific communication. Engaging Gen Z must happen on equal footing and through the digital channels they use. Complex financial topics should be presented in an understandable, real-world context.
Third: Continuous validation through simulations. Before new ESG features or campaign claims are physically rolled out, they should be tested using simulation tools like Minds. This not only saves significant costs but also delivers precise insights in under an hour on how the target audience will react to the planned measures.
By bypassing expensive, time-consuming physical panels, regional banks can drastically shorten their innovation cycles and react faster to market changes. The high accuracy of Minds simulations ensures that decisions are based on valid data, sustainably strengthening the trust of the younger generation.
