Monzo has confirmed that a technical fault which stopped customers from making card payments or transfers has been fixed, restoring full functionality across its app and backup services.
The digital bank first flagged the disruption on social media platform X, stating it had "identified some issues" and switched on its independent backup system, Monzo Stand-in, designed to keep essential banking functions running while the main issue was addressed.
What went wrong with the backup system?
Despite Monzo's assurances, several customers reported that the stand-in service failed to work as intended, leaving them unable to complete basic transactions.
Your "backup" bank does not have the functionality you state it does. I can't make bank transfers right now,
another user wrote, echoing similar frustrations posted publicly. One customer added:
I can't use my card for anything at the moment,
highlighting that the disruption extended beyond transfers to everyday card use.
How did Monzo respond?
Monzo acknowledged the shortfall, admitting under its original post that the stand-in system was "not working as expected" for some users. A short time later, a company spokesperson confirmed that services had been fully restored.
We're sorry for any inconvenience and thank customers for their patience,
the spokesperson said, adding that all systems were now "back up and running."
What is Monzo Stand-in and how does it work?
According to Crowdfund Insider, Monzo's stand-in backup system is built to maintain core banking functions—such as card payments, cash withdrawals, card freezes and bank transfers—during outages of the main platform. Monzo has previously stated that this backup infrastructure is capable of processing roughly 99.9 percent of payments even when its primary systems are down, according to LADbible. During the fault, Monzo said users would still be able to "make card payments, withdraw cash, freeze your card, send and receive bank transfers, and more" through the stand-in service, even if some experienced problems with it in practice.
How widespread was the disruption?
A live outage tracker referenced by the Daily Record recorded around 1,891 user reports of problems, with further complaints continuing to arrive on 19 August 2026, suggesting the issue affected a substantial number of customers before being resolved. Separately, a discussion thread on Monzo's official community forum, titled "Monzo has crashed" and dated 13 August 2026, pointed to customer conversations around a related recent incident, according to the Monzo community forum.
Has this happened before?
Monzo, founded in 2015 as a mobile-first alternative to traditional branch banking, has previously relied on its stand-in system during past technical difficulties. In an earlier incident, the bank said it temporarily activated the autonomous backup service while investigating a fault, before restoring normal access to its main app, according to a national broadcaster's report. The company now serves more than 16 million personal and business customers worldwide.
What happens next?
At the time of the most recent update, Monzo's official status page indicated the company was "continuing to investigate this issue," suggesting further updates on the cause and any long-term fixes may follow, according to a national broadcaster's report.
