MUFG Taps Generative AI for Retail Banking with New ChatGPT App Integration

Mitsubishi UFJ Financial Group (MUFG), its retail banking arm MUFG Bank, and consolidated subsidiary Moneytree have rolled out a generative AI-backed service integrated with OpenAI’s "Apps in ChatGPT," the companies announced Thursday.

The rollout marks a concrete step in MUFG’s broader retail AI strategy originally unveiled in November 2025. By embedding Moneytree’s financial data infrastructure (Moneytree LINK) into ChatGPT, the partnership aims to streamline retail asset management, letting users check balances and view categorized spending logs directly via natural language prompts instead of shifting between separate banking apps.

Existing Moneytree users can link their accounts within ChatGPT using current credentials. To ease data privacy concerns surrounding AI-driven FinTech, Moneytree stated it will enforce strict data limitations, ensuring only essential financial records are accessed, alongside maintaining ongoing transparency and access controls under its privacy guidelines with OpenAI.

Management indicated that initial operations will prioritize data legibility and user access, with iterative functional expansions scheduled in subsequent phases.
