Nevertheless, we may soon witness an acceleration in adoption rates, as Generative AI has already proven successful in banking and fintech.

How can Generative AI drive success and revenue in this sector? What risks are associated with these implementations, and how can they be mitigated? How can businesses ensure that generative AI delivers the desired outcomes in such a demanding and regulated environment? In our article, we delve into the subject of Generative AI in banking and finance industries, examining successful use cases, statistics, and emerging trends. The future of AI in fintech and banking is now – but what does it mean for the sector?

What is generative AI in banking and finance?

Generative AI leverages machine learning models, particularly deep neural networks, to create new content based on patterns learned from large datasets. This process often involves models such as Generative Adversarial Networks (GANs) or transformers. In GANs, two neural networks—the generator and the discriminator—compete with one another. The generator attempts to create realistic outputs (like images or text), while the discriminator seeks to determine whether the output is real or generated. Through this ongoing competition, the generator improves its ability to produce highly convincing data.

AI vs. generative AI in financial institutions and banking

While traditional AI is already prevalent in today’s banking and financial sectors, Generative AI is just starting to make waves. Though it may not yet be reliable for complex financial tasks, such as predicting stock prices or market trends—where accuracy and historical data modeling are crucial—it excels in simplifying data interpretation.

Surprisingly, many tasks in finance involve creativity and significant time and effort, making them ideal candidates for Generative AI. The technology can generate new data, simulate scenarios, and automate content production, even in real-time.

Key use cases of generative AI in banking and finance

With the increasing demand for fintech and banking services, Generative AI has become instrumental in covering many traditionally labor-intensive tasks. From customer service to personalized app features, sharing information, and generating insights, Generative AI is emerging as a cornerstone of growth. Here are some key ways companies are integrating this technology into their processes.

Streamlining customer service with generative AI assistants and chatbots

Generative AI assistants are becoming increasingly common across industries, facilitating more natural and effective interactions that allow customers to resolve their issues without hassle. While traditional chatbots relied on rigid scenarios that often frustrated users, Generative AI chatbots can handle any query and carry conversations forward in a more natural, human-like manner.

Given that many requests involve stressful situations—such as account blockages or suspicious activity—Generative AI significantly improves the experience, making interactions seamless without requiring customers to phrase their questions in a specific way.

Moreover, Generative AI chatbots can also empower customers in the highly regulated finance industry, where complex jargon can create additional hurdles. These AI-driven tools can help ensure compliance by providing clear information about regulatory changes, offering legally compliant advice, and ensuring that documentation processes are followed correctly.

It’s no surprise that many banks globally have already transitioned to Generative AI assistants or are planning to do so in the near future. In Europe, ING has been a pioneer in this field, while in Asia, Singapore’s OCBC Bank is leading the way.

Extracting insights for credit risk assessment and scoring

Traditional credit scoring systems rely on static models and predefined metrics, such as income, credit history, or debt-to-income ratio. In contrast, deep learning models can analyze more complex and diverse data sets, including non-traditional financial information such as transaction patterns, spending behaviours, and even social data. This approach enables a more nuanced and personalized assessment of a borrower’s creditworthiness.

McKinsey notes that certain banks employ modular credit decision models, which allow them to integrate diverse data streams, such as open banking data and customer behaviour patterns, to derive more accurate credit signals. This flexibility helps banks to react faster to market disruptions, make more precise lending decisions, and target new customer segments efficiently​

Generative AI models also provide enhanced insights into customer data, streamlining credit scoring processes. Analysts can generate visualizations of specific insights, improving their understanding of the often complex habits and patterns that could impact a customer’s reliability as a credit payer and influence overall credit risk.
