KBRA affirms all of its outstanding ratings for BANK 2017-BNK8, a $968.3 million CMBS conduit transaction. The affirmations follow a surveillance review of the transaction, which has exhibited a worsening in pool performance compared to KBRA's last ratings change in November 2024, however the transaction has benefited across the capital structure due to loan payoffs, amortization, and defeasances and the magnitude of the changes does not warrant ratings adjustments at this time.

As of the October 2025 remittance period, there is one (10.3%) specially serviced loan, which is 90+ days delinquent. KBRA identified eight K-LOCs (35.6%), including the specially serviced loan, of which four (26.2%) have estimated losses. The K-LOCs are depicted in the table below.
