Northern Trust Deploys AI Agents for Institutional Client Onboarding with Microsoft
Vendor-reported results: institutional onboarding document mapping cut from about 2.5 weeks to 3 days, with 3.5% of documents escalated to human review.
Northern Trust, a major United States custodian bank, has published details of AI agents built with Microsoft's Frontier Company to process onboarding documentation for new institutional clients such as family offices, pension funds, and asset managers. According to the announcement, mapping a new client's transaction history and cash flows across multiple formats to the bank's internal platform, previously taking about two and a half weeks, has been reduced to approximately three days.
Vendor-reported results indicate a first-pass quality score of 96.5 percent, combining precision and recall, with the remaining 3.5 percent of documents escalated to human reviewers. The bank described keeping a human in the loop as an explicit design decision to avoid incorrect information. Routine reconciliation was run before go-live, and all client data remains within Northern Trust rather than being used to train external models. These performance figures have not been externally audited.
The bank reports 23,000 employees trained on Copilot and more than 15,000 internal agents created by staff. Northern Trust is now exploring agents for additional products.
