AI in banking: Transforming finance for the digital age

Discover how AI is transforming the banking sector through automation, enhanced customer service, and improved risk management.

A customer opens their banking app and sees exactly what they need: A gentle nudge about that subscription they forgot to cancel; a heads-up about an unusual spending pattern; a perfectly timed suggestion for a savings product that makes sense for their financial goals. This is AI in banking, and it's already happening at leading financial institutions worldwide.

For tech leaders in financial services, artificial intelligence can now represent something far more practical than buzzword-heavy promises. The applications of AI in banking can help financial institutions to spot fraudulent transactions in milliseconds, predict which business loans might run into trouble before they do, or help treasury teams forecast cash flow with unprecedented accuracy. Generative AI technology can handle much many complex financial workflows, augmenting human judgment.

Let’s take a look at how generative AI in banking is making a difference to both financial organizations and their customers.

##### AI in banking and finance: how does it work?

The role of AI in banking is to take huge amounts of raw data and turn them into insights within secure environments and in accordance to regulatory mandates. Banks already collect a vast trove of sensitive information—from customer transactions, credit histories, market data, and their own operations—and it’s often not used to its maximum potential. Using secure AI in banking means this data can be used to customize and fine-tune large language models (LLMs) to deliver tailored and unique solutions. For example, to spot trends and suggest ways forward, be that in fraud detection, customer experience, potential new products, or even the big-ticket strategic decisions that help drive growth.

AI in financial services can play multiple roles to help drive productivity and growth, including pattern identification, decision support, and continuous learning.

###### Pattern identification

Different AI techniques work to support different banking jobs. For example, neural networks can pair well with complex data. These deep learning models can find connections between dozens of factors that traditional statistical models may miss completely.

Natural language processing (NLP) can turn text into useful information. NLP algorithms read customer service conversations to spot emerging problems, scan regulatory documents to find compliance requirements, and monitor social media to measure brand sentiment. Advanced NLP models could even pick up on subtle emotional signals in customer messages that predict when someone might close their account or when they're ready to buy something.

Computer vision handles visual information from check images, ID documents, and customer behavior in bank branches. Optical character recognition pulls data from handwritten forms and documents. Video monitoring tracks the number of people visiting branches to help with staffing decisions.

In all of these uses of AI in banking, the models are deployed to recognize patterns that can support more productive banking operations.

###### Decision support

AI can bring together multiple data streams in coordinated workflows. Take fraud detection. AI can analyze multiple data streams, such as transaction records, customer behavior data, and social media posts, to identify anomalous transactions and high-risk customers. By coordinating these workflows, banks can detect and prevent fraud more effectively, protecting customers and optimizing revenues.

###### Continuous learning

AI gets better by looking at what happened and learning from it. Was that fraud alert correctly labeled? Did the customer like that product recommendation? Did the loan go as predicted? This feedback loop, called reinforcement learning, helps to make AI smarter over time.

Advanced AI is able to change its approach based on results, so it can keep up with changing customer needs and market conditions. A customer service AI that solves problems well reinforces those approaches, while failed interactions trigger adjustments to improve future performance.

##### Generative AI in banking versus traditional AI in banking

Traditional AI has been working behind the scenes in banking for longer than you may realize. Credit scoring algorithms look at loan applications using statistical models to check income, debt ratios, and payment histories. Algorithmic trading platforms execute millions of trades based on market data and input rules. Risk management departments use predictive models to figure out which loans might default, and to set interest rates.

These conventional AI tools are great at processing data and making predictions. They look at historical information to spot problems, assess risks, and make decision recommendations like approve or deny, buy or sell.

Generative AI in finance works differently. Instead of looking at existing data to make predictions, it can create new content based on what it learned during its training and with connections to real-time knowledge hubs. Generative AI is able to write human-like text, create personalized financial reports, and build tailored investment recommendations that explain complex concepts in simple language.

The differences between generative AI and traditional AI in banking show up clearly in real applications. Traditional AI might catch a fraudulent transaction, but generative AI can write a personalized explanation for the customer about why the transaction was flagged. Where traditional...
