BMO Bank, N.A.

What the CFPB Complaint Record Shows for BMO Bank, N.A.

The CFPB Consumer Complaint Database has logged 6,428 complaints against BMO Bank, N.A. overall, with 1,257 of those filed in the trailing 12 months. Reports have come from consumers in 53 states and territories, making this a nationwide complaint footprint. The single largest complaint category is "Checking or savings account," which consistently leads the product-level breakdown and signals where consumer friction is most acute. Within that category, the most frequently cited specific issue is "Managing an account" — a useful starting point for anyone trying to understand what goes wrong most often in the company's consumer interactions.

BMO Bank, N.A.'s timely response rate stands at 99.9%, meaning that share of CFPB-forwarded complaints received a company reply within the 15-day window the Bureau expects. That figure is at or above the industry benchmark and suggests the company's intake and escalation processes are functioning as designed. Consumers formally disputed the company's response in 23.8% of resolved cases, a signal of how often the initial resolution failed to satisfy the complainant. Of complaints that were resolved, 24.8% closed with some form of monetary or non-monetary relief to the consumer.

Complaint counts alone do not tell the full story — larger institutions with more customers will naturally generate more complaints in absolute terms. The more informative signals are the direction of the yearly trend shown above, the state-level concentration (which hints at regional servicing issues or regulatory exposure), and the ratio of monetary-relief closures to closed-without-relief outcomes. Taken together, these fields give consumers a reasonable empirical basis for deciding whether to escalate a dispute, and give researchers a starting point for investigating institutional patterns.
