Co-op Bank customers hit by Sunday banking outage as App, USSD fail

On Sunday, November 15, 2026, Co-operative Bank of Kenya experienced a technical disruption that disrupted its digital banking services. Customers were unable to log into the MCo-opCash mobile banking application or access services through the bank's USSD platform, *667#. The issue came to light after customers shared their difficulties on social media platform X.

One customer, Felix Kaka (@kakafeliki), questioned the bank's official X account, stating he was unable to access his account or check his balance through either the app or USSD. "I am unable to access and transact on my account; both on the app and USSD? I can't even see my balance, what's the matter???" Kaka posted.

Co-operative Bank acknowledged the technical problem and stated that its support team was working to restore normal services. The bank did not disclose the cause of the disruption or the duration of the outage. It also did not specify the extent of the affected services.

The incident underscores the reliance on digital banking platforms, with customers using mobile applications and USSD services for financial transactions. Customers with pending transactions should contact the bank's communication centre or visit operational branches for assistance. Customers are advised to avoid initiating transactions with unclear status to prevent duplicate payments. The bank is expected to provide further updates once its technical teams have restored services.
