The TellerScore is our own summary of the figures this institution reports publicly; it is not issued or endorsed by any government agency. It is not a prediction, and deposits within insurance limits are protected either way.

The score has been essentially flat from Q2 2025 to Q2 2026 (63 → 64).

Percentile against banks of similar size nationwide (100th = best among peers; for ratios where lower is better, the scale is flipped).

Over the last three years, the CFPB forwarded 183 consumer complaints about BOK FINANCIAL CORP to the company (75 in the last 12 months). 100.0% received a timely response. That is 4.6 complaints per $1 billion of deposits, versus a median of 8.5 among institutions with complaint data.

Complaint counts reflect volume, not validity: the CFPB does not verify complaints, and large institutions receive more because they serve more customers. Complaints are filed under the parent company name, which may cover affiliates.
