Top Use Cases of Artificial Intelligence in Banks

Hello!

AI is constantly evolving. Financial institutions are already leveraging AI technology to detect fraud and unusual transactions, personalize services, automate credit decisions, and apply natural language processing to text documents.

Banks have steadily improved customer service by adopting technology tailored to their operations. The first ATMs appeared in 1960, followed by payment and transaction cards a decade later.

Online banking emerged at the beginning of the century, with mobile banking arriving in 2010. Today’s digital era continues to unlock new opportunities for the financial system.

Artificial intelligence is now widely deployed across banks and financial institutions. By adopting AI applications, banks are projected to save $447 billion annually. Here are some prominent examples.

Mobile Banking

AI-powered mobile apps are becoming increasingly personalized, proactive, and sophisticated. For instance, a Canadian bank has integrated Siri into its iOS app, allowing users to send money with a simple voice command such as “Hey Siri, send $20 to Alex!” and confirm the transaction via Touch ID.

AI has enabled banks to generate 66% more revenue through mobile banking compared with traditional branch visits. To enhance service quality and remain competitive, banks continue to monitor emerging technologies closely.

AI Chatbots

Chatbots are AI-enabled conversational interfaces and represent the most common application of AI in banking. They allow banks to engage with customers at scale without significant additional costs. Research indicates that chatbots save financial institutions an average of four minutes per interaction.

Banks integrate chatbot services directly into mobile apps, where customers frequently conduct transactions. This approach helps capture user attention and strengthens brand recognition.

The Australian Commonwealth Bank launched its Cuba ChatBot, which has successfully assisted more than 500,000 customers with tasks such as card activation, balance checks, and cash withdrawals.

Bank of America introduced a chatbot that sends balance notifications, offers personalized saving recommendations, and provides credit-report updates, helping clients make more informed financial decisions.

Data Collection and Analysis

Banks process millions of transactions daily, generating vast amounts of information. Organizing and analyzing this data manually is challenging, especially when identifying patterns across thousands of clients.

The traditional approach of inviting clients to in-person meetings with relationship managers familiar with their financial history is becoming outdated.

Banks now harness transaction data to develop innovative products and refine risk-management strategies. AI-driven applications collect and analyze this information to enhance user experience, support lending decisions, and detect fraud. Companies that have implemented Big Data analytics report an average revenue increase of 8% and a 10% reduction in costs.

Risk Management

Extending credit remains a core challenge for banks. Lending to customers who later default can create serious financial difficulties. In 2026, U.S. credit card delinquencies rose by 1.4% over six months.

AI-powered systems can accurately evaluate customer credit histories to help prevent defaults. By analyzing transaction patterns within mobile banking apps, banks can anticipate risks such as potential bankruptcy or fraudulent activity before issuing loans.

Transaction Data Enrichment

Both financial institutions and consumers benefit from clearer financial insights. AI and machine learning transform cryptic transaction strings into readable details, displaying the merchant’s name, address, and city—reflecting the actual location of purchase rather than corporate headquarters.

This clarity reduces customer-service inquiries and fraud investigation costs, as customers can easily recognize their purchases.

Improved descriptions also enable developers to place financial data in context, simplifying categorization for budgeting, credit scoring, and spending analysis.

Data Security

According to the Federal Trade Commission’s 2026 report, credit card fraud remains the most common form of personal data theft.

AI-based systems help counter such threats by monitoring customer behavior, spending patterns, and location data, triggering security alerts when anomalies are detected. ABI Research projects that the cybersecurity analytics and AI market will reach $96 billion by 2026.

Amazon acquired the AI cybersecurity startup harvest.AI and launched Macie, a machine-learning service that automatically detects and classifies data stored in Amazon S3.

Closing Note

AI offers numerous applications in the finance sector. According to an OpenText survey, nearly 80% of banks recognize AI’s benefits, 75% already use the technology, and approximately 46% plan to implement AI-based systems in the near future.

AI-powered solutions have become integral to banks’ development strategies, helping them stay competitive while reducing operating costs, improving customer service, and automating routine processes.
