In recent years, the banking industry has witnessed a significant transformation with the advent of artificial intelligence in fintech. This article provides a comprehensive overview of the state of AI banking, highlighting the types of AI use cases, challenges, current use cases, and emerging trends.

The current state of AI in the banking sector

The banking industry has traditionally been the driving force behind implementing innovative solutions on a large scale — for instance, the introduction of ATMs in the 1960s or the adoption of mobile banking apps in the previous decade. As of today, disruptive artificial intelligence (AI) technologies enable banks to pursue four main goals:

  • Personalize customer experiences
  • Offer unique omnichannel interactions
  • Accelerate innovation cycles
  • Increase profitability

As of 2024, AI has transformed various aspects of banking, from customer service and risk management to fraud detection and personalized financial advice. A Business Insider report indicates that 75% of banks with over $100 billion in assets implemented AI-centered strategies and tools in 2022.

Conversational and generative AI in banking

Conversational AI (CAI) in banking encompasses the implementation of artificial intelligence technologies such as natural language processing (NLP), natural language understanding (NLU), and machine learning to enable human-like interactions between banks and their customers. Conversational AI involves using chatbots, virtual assistants, and voice-enabled systems that can understand and respond to customer queries, provide information, and assist with various banking services.

Conversational AI solutions in banking fall under three main types depending on their purpose.

  1. Virtual assistants: These are personal assistants (like Amazon Alexa, Google Assistant, and Siri) designed to interact with customers and assist them in various banking-related tasks, such as personalized customer support, account management, product recommendations, and appointment scheduling. 
  2. Virtual agents: Although somewhat similar to AI-powered assistants, virtual agents act as bank representatives to fulfill various business objectives. A prominent example of a virtual agent is Capital One's Eno, engaging with customers to provide banking-related services and support.
  3. Natural language processing (NLP) systems: NLP systems enable banks to interpret and analyze unstructured customer text data, such as emails, chat logs, or social media messages. NLP systems help extract the main intent from customer communications, allowing banks to identify customer needs and respond effectively.

Generative AI (GAI) in banking refers to the application of generative language tools and models (think ChatGPT or DALL-E) to create new and original data or content within the banking sector. Generative AI models can learn from existing data patterns and generate new outputs that mimic the characteristics of the training data.

Generative AI in banking falls into different types based on its specific applications and techniques.

  1. Generative adversarial networks (GANs): GANs are a popular type of generative AI model that consists of two components: a generator and a discriminator. GANs are trained in a competitive manner, meaning that the generator creates synthetic data samples and the discriminator distinguishes between real and generated data. Banks use GANs for tasks such as generating synthetic transaction data for fraud detection or creating synthetic market data for risk assessment.
  2. Language generation models: Language generation models, such as OpenAI's GPT, are widely used in banking for tasks related to content generation and natural language processing. These models are trained on large text corpora and can generate coherent and contextually relevant textual content. Banks use such models to offer personalized financial advice, automate reports, and improve customer communication.
  3. Market simulators: Market simulators leverage generative AI techniques to create synthetic market data that mimics real-world market conditions. These simulators generate market scenarios and data to assess portfolio performance, optimize investment strategies, and perform stress testing, enabling banks to evaluate the potential impact of different market conditions on their portfolios.
  4. Synthetic data generation: Generative AI for banking is used to create synthetic data that closely resembles real customer or transaction data while preserving privacy. This synthetic data allows banks to test and train AI models, conduct data analysis, or share data with their external partners without compromising sensitive customer information.

Key takeaways: 

Although both types can be applied independently, combining generative AI with conversational AI provides the maximum value. Conversational AI ensures seamless and guided conversations, providing essential boundaries for generative AI. Moreover, CAI enriches interactions with customized company-specific responses, offering valuable information such as operating hours, office locations, and protocols.

In turn, generative AI brings creativity, fluidity, and adaptability to the conversation. This dynamic interplay between these two AI approaches results in a transformative experience, empowering banks to achieve new levels of efficiency and engagement with their audience.
