Harnessing Data and Large Language Models for Strategic Growth

November 4, 2025

For years, business banking teams have worked hard to understand their commercial clients, but the tools haven’t kept pace. Relationship managers still rely on spreadsheets, static reports and periodic check-ins to gauge whether a business might need new treasury services, lending solutions or better account structures.

Why Financial Institutions Are Missing Opportunities
Much of the answer lies in the data banks and credit unions already collect. Account statements, for example, contain rich insights into cash flow patterns, revenue cycles and payment behavior. Yet most institutions lack the bandwidth or technology to extract these insights at scale. Without the ability to analyze this data efficiently, banks and credit unions risk losing competitive advantage to institutions and fintechs that can.

The Role of Large Language Models
Large language models (LLMs) are advanced machine learning systems designed to understand context and patterns in unstructured data. Applied to commercial account data, LLMs can help banks and credit unions:

1. Categorize transactions automatically. LLMs can identify payroll, vendor payments and merchant deposits, creating a dynamic financial profile of a business.
2. Spot treasury and lending opportunities. Recurring cash shortfalls or spikes in vendor payments may highlight potential needs for cash management, lockbox or working capital solutions.
3. Identify risk and growth trends. Unusual transaction activity may signal exposure, while rapid deposit growth could indicate a scaling business that requires proactive engagement.

The value is not in replacing human relationship managers but in equipping them with faster, more accurate insights.

Strategic Considerations for Executives
Before adopting LLM-powered strategies, leadership teams should consider:

• Partnerships over in-house development. Not all institutions have the resources or expertise to build artificial intelligence (AI) solutions internally. Partnering with experienced firms can accelerate time-to-value and reduce complexity.
• Outcome-driven adoption. Focus on insights that inform business decisions, not just technology deployment.
• Integration with existing workflows. New capabilities should enhance, not disrupt, existing processes.
• Talent and cultural alignment. Teams need data literacy and comfort with AI-assisted decision-making to realize value.

Learning From the Consumer Side
Consumer banking has already demonstrated how technology can reshape customer behavior. Beyond simplifying direct deposit switching, automation now enables personalized budgeting, instant notifications, predictive insights and frictionless digital payments. These innovations have raised customer expectations for speed, convenience, and proactive guidance. Business banking is poised for a similar transformation. By combining institutional data with intelligent systems, financial institutions can deliver tailored, anticipatory service at scale; making interactions faster, more relevant and more valuable for commercial clients; allowing institutions to act proactively rather than reactively.

Competition and Strategic Urgency
The commercial banking landscape is evolving quickly. Megabanks, fintechs and neobanks are investing heavily in AI-driven insights to win market share. Regional banks and credit unions that embrace intelligent data analysis and strategic fintech partnerships can avoid playing catch-up.

The organizations that move thoughtfully and deliberately are more likely to capture primary banking relationships, enhance loyalty and strengthen long-term revenue growth. Those that delay investment may find themselves at a disadvantage in an increasingly competitive market.

Key Takeaways for Executives

• Prioritize understanding your commercial clients’ data. Insight drives action.
• Consider partnerships carefully. Leverage external expertise without overcommitting internal resources.
• Focus on workflow integration. Technology is most effective when it enhances existing processes.
• Build internal capabilities. Data literacy and AI adoption are critical to long-term success.


The Competitive Edge Is in the Partnership
The commercial banking landscape is evolving rapidly, with big banks and fintechs investing heavily in AI-driven insights. Regional banks and credit unions, however, don’t need to play catch-up; they can advance by strategically partnering with firms that specialize in emerging technologies. Leveraging data effectively and tools like large language models enables institutions to understand clients more clearly, anticipate needs, reduce friction and deliver value faster, positioning them to compete and thrive in a fast-moving market.
