Summary

Financial institutions have extensively experimented with virtual assistants and chatbots, but few initiatives have achieved sustainable scale. Consumers are increasingly willing to engage with conversational AI for financial queries, with a growing number using these tools for product comparisons, financial concepts, and guidance. Notably, a significant portion of these interactions occur outside banks' proprietary channels. Forrester data from March 2026 indicates that 31% of consumers in the US, Canada, and the UK use conversational AI for personal finance questions, and 24% of these users rely on third-party tools like ChatGPT or Gemini. This trend poses a risk of interface-level disintermediation, where external AI assistants become the primary gateway for customer financial interactions, potentially shifting customer relationships away from bank-owned channels. Scaling conversational banking requires intentional design across technology, data, and operating frameworks, with trust, explainability, and accountability embedded from the start.

Key takeaway

For Product Managers and CTOs evaluating digital engagement strategies, recognize that the shift to third-party conversational AI for financial queries presents a significant disintermediation risk. You must move beyond basic chatbots to design comprehensive conversational banking experiences that integrate trust and accountability, ensuring your bank remains a primary interface for customer financial interactions rather than being bypassed by external AI tools.
