Lloyds Banking Group Hit by Technical Glitch Exposing Customer Data On the morning of March 12, 2026, customers of Lloyds, Halifax, and Bank of Scotland reported a serious technical issue in their mobile banking apps. Users were shown other customers’ account details, including names, sort codes, spending histories dating back to December, and unfamiliar transactions. Lloyds Banking Group acknowledged the incident as a "technical glitch" and stated that no unauthorized access or financial theft occurred. The bank assured customers that account balances remained accurate and advised logging out and back in to resolve the issue, which worked for many. However, some users continued to experience problems as investigations proceeded. Despite the bank’s reassurances, the brief exposure of sensitive data sparked privacy concerns. Social media reactions highlighted frustration, with one user, Matt Doogue, calling it a "huge data breach" after seeing transactions from other accounts. The incident underscores the risks of technical failures in digital banking systems.
