AI Trends in Banking: What Financial Institutions Need to Know

The banking industry is no stranger to technological disruption. From ATMs to online portals to mobile apps, financial institutions have always adapted to stay competitive. But the pace of change is accelerating — and artificial intelligence (AI) is leading the charge.

2023 marked the moment generative AI burst into the mainstream. In 2024, many institutions shifted from exploration to early deployment. Now, the focus is squarely on strategic scaling. 

According to McKinsey, AI could unlock $200 billion to $340 billion in value across the banking sector, with forward-thinking financial institutions already using it to drive personalization, operational efficiency, and proactive risk management.

Simply put, opportunity abounds. To help you prepare for what’s ahead, we’ve compiled nine essential AI trends in banking. Each represents a unique opportunity for growth, transformation, and improved customer experience.

1. Voice AI Becomes the New IVR

Traditional interactive voice response (IVR) systems rely on rigid menu trees and numeric inputs, often frustrating callers and increasing call abandonment rates. Voice AI augments these systems with conversational intelligence powered by natural language processing (NLP).

NLP is a branch of artificial intelligence that enables machines to understand, interpret, and generate human language. In the context of the banking sector, NLP allows AI-powered Voice Assistants to comprehend customer requests phrased in everyday speech, not just predefined commands. 

This means instead of pressing '1' for account balance or '2' for loan information, users can simply say, "What’s my current checking balance?" or "I need help applying for a car loan," and the system will recognize the intent.

NLP systems rely on large language models trained on vast datasets. These models identify linguistic patterns, analyze sentence structure, and factor in contextual cues to determine the user’s intent. As the system interacts with more customers, it continues learning and refining its accuracy. 

Combined with speech recognition and text-to-speech capabilities, NLP enables voice AI to carry out dynamic, intelligent conversations, making the customer experience smoother, faster, and more natural.

Key advantages of voice AI include:

• 24/7 Availability: Customers can access support anytime without being restricted by business hours.
• Conversational Clarity: AI understands intent, handles follow-ups, and routes calls more effectively than rule-based menus.
• Scalability: Institutions can manage call surges without increasing headcount — a benefit that also supports cost efficiency. 

For example, Posh’s Voice Assistant automates 91% of inbound requests and can cut call abandonment by up to 93%. Not only does that improve customer experience, but it also frees agents to focus on more complex tasks. As voice AI continues to improve, it will become the default for inbound banking support.

2. Hyper-Personalization Through Predictive AI

Globally, 64% of consumers prefer to buy from companies that tailor their experience to their unique wants and needs — and that goes for financial services, too. 

It means going beyond generic greetings or one-size-fits-all product suggestions. Hyper-personalization involves customizing experiences, communications, and recommendations to each individual based on their behaviors, preferences, and goals. 

This is made possible through predictive AI, which uses machine learning algorithms to analyze large volumes of customer data — including transaction history, spending habits, preferred channels, and even engagement patterns with past communications. From there, the AI can anticipate customer needs and deliver timely, relevant recommendations or support.

With predictive analytics and machine learning, banks can:

• Analyze transaction patterns, device behaviors, and interaction history.
• Deliver personalized recommendations for savings, investment, and credit offers.
• Send proactive nudges (e.g., reminders for upcoming payments or overdraft risk alerts).

What sets this apart from traditional personalization is the proactive and adaptive nature of AI-driven insights. Rather than simply responding to customer actions, the system forecasts what a customer might need next — enabling financial institutions to serve as true partners in financial well-being.

According to Accenture, generative AI is helping to restore the emotional connection that customers used to associate with in-person banking — now delivered digitally, at scale. Banks that invest in hyper-personalization not only deepen loyalty but also uncover new cross-sell and upsell opportunities through smarter engagement.

3. Omnichannel AI Integration

Today’s customer journey is nonlinear. A user might start a mortgage application on mobile, ask a question via chatbot, and finalize it in a branch. If those touchpoints don’t connect, the customer experience suffers.

Disconnected channels often mean customers have to repeat themselves, re-enter information, or start over entirely — wasting time and eroding trust. In contrast, customers increasingly expect their bank to "remember" their context across every channel. Whether they’re interacting via mobile app, website, voice call, or in person, they want the experience to feel seamless, intelligent, and continuous.

Omnichannel AI addresses this by synchronizing context and data across:

• Voice and Chat Channels: Ensuring conversations move fluidly from automated bots to live agents without losing context.
• Mobile and Desktop Digital Banking Portals: Allowing customers to pick up where they left off across devices.
• In-Branch and Contact Center Interactions: Giving staff real-time visibility into the customer’s digital journey.

With omnichannel AI, every interaction feels like a continuation, not a restart.

4. AI-Powered Cybersecurity and Fraud Prevention

Fraud tactics are evolving fast — and so are defenses. According to EY, attackers are using artificial intelligence to craft more sophisticated and convincing scams. 

Deepfake audio can mimic a customer’s voice to bypass identity checks. Phishing emails generated by large language models are harder to detect because they mirror real communication styles. AI can even analyze call center procedures to identify the best points of attack.

The best defense? Ironically, it’s also AI systems.

Modern financial institutions are turning to AI-powered cybersecurity and fraud detection tools to counteract these advanced threats. Key applications include:

• Anomaly Detection: Machine learning models continuously monitor account activity and flag deviations from typical behavior — such as sudden overseas logins or unusually large transfers. These systems operate in real time and improve with each data point, helping identify fraud as it happens, not after.
• Synthetic Fraud Simulation: Generative AI can create hypothetical fraud scenarios, enabling teams to stress-test their systems and train models against novel threats before they occur. This proactive strategy helps banks stay ahead of emerging tactics, rather than merely react.
• Behavioral Biometrics: Instead of relying solely on credentials like passwords, AI can analyze how a user interacts with digital platforms — including typing speed, device angle, and navigation habits. These subtle biometric patterns create a unique behavioral fingerprint, making it harder for imposters to break in.

For instance, JPMorgan Chase used AI to reduce account validation rejections by 20% while improving fraud prevention and cost savings. 

5. Knowledge AI Empowers Internal Teams

Banking employees are often overwhelmed by the volume of tools and documentation they need to navigate. Policies, procedures, product details, and compliance protocols may live across disconnected systems or documents, leading to wasted time, inconsistent answers, and employee frustration.

That’s where knowledge AI comes in. These intelligent assistants integrate with a financial institution’s internal knowledge base and use natural language processing to deliver real-time, accurate answers to employee queries — no searching through PDFs or message threads required.

Knowledge Assistants solve this by:

• Offering instant answers to policy, product, or system questions.
• Reducing onboarding time for new hires.
• Unifying siloed information into a single interface.

For example, Posh’s Knowledge Assistant helped Hudson Valley Credit Union save 143 hours of employee time per month. The result? A more confident workforce, fewer escalations, and a better customer experience at every touchpoint.

As banks roll out new services, update compliance protocols, or merge operations across locations, Knowledge AI will become a critical tool for scaling expertise and ensuring institutional agility.

6. Agentic AI Takes Over Complex Workflows

Agentic AI is a step beyond traditional automation. Instead of following fixed workflows, it dynamically plans, adapts, and executes tasks based on goals and context.

Examples of agentic AI in banking include:

• Processing a loan application end-to-end (from intake to approval).
• Escalating support requests based on tone and urgency.
• Updating customer records while syncing with multiple back-end systems.

As IBM explains, agentic AI combines the intelligence of AI with the autonomy of decision-making. It turns manual processes into smart, adaptable workflows that require little to no human input.

7. Scalable AI Infrastructure for Demand Spikes

Banking isn't always steady-state. 

Institutions regularly face service spikes — whether predictable (like tax season or new product launches) or sudden (like interest rate changes, fraud events, or system outages). During these high-demand periods, legacy systems and human-only support models struggle to keep up, often resulting in long wait times, frustrated customers, and overwhelmed staff.

Scalable AI infrastructure addresses these challenges by providing elasticity — the ability to scale support capacity in real time without the need to onboard and train temporary staff.

Here’s how AI helps banks stay responsive and resilient:

• Automated Load Balancing: AI-powered Voice and Digital Assistants can absorb large volumes of inquiries, routing only the most complex or urgent issues to live agents.
• Instant Availability Across Channels: Whether customers call, chat, or use a mobile app, AI tools offer consistent, around-the-clock support — no queue required.
• Efficient Resource Allocation: With AI handling common questions, human agents can focus on high-value interactions like loan disputes or fraud resolution.

Case in point: Citadel Credit Union deployed Posh’s AI tools during a core conversion — a notoriously stressful time for both customers and staff. The AI system handled more than 4 million interactions and saved $663,000 in operational costs, all while maintaining service quality during a period of major change.

8. AI-Driven Forecasting and Risk Management

Predictive AI is also transforming how banks assess risk management and forecast trends. Capabilities include:

• Churn Prediction: Identifying customers likely to leave and suggesting retention offers.
• Delinquency Risk Scoring: Proactively flagging loans that might default.
• Behavioral Segmentation: Grouping customers based on needs and likelihood of conversion.

McKinsey notes that leading institutions use these insights to intervene early, personalize outreach, and reduce losses, ultimately improving financial outcomes for both the bank and the customer.

9. Conversational AI for Digital Self-Service

Customers want fast, accurate answers — without having to call a contact center. AI-powered website assistants like Posh Answers turn static sites into dynamic, searchable knowledge hubs.

Key features include:

• Conversational Search: Users can ask natural-language questions (e.g., “How do I reset my password?”) and get clear, contextual responses.
• Automated Issue Resolution: Answers handles routine inquiries about loan applications, routing numbers, business hours, and more.
• Real-Time Updates: Institutions can instantly update content without IT involvement, ensuring consistent, accurate information.

Whether helping customers find answers at midnight or guiding them through complex topics, AI initiatives like Posh Answers are redefining online self-service.
