Singapore lender Oversea-Chinese Banking Corporation Ltd. said it has fully restored all services after a disruption affecting consumer and business banking customers earlier Monday.

OCBC is investigating the cause of the technical glitch that hit both physical and online services at 8:33 am local time, the city-state’s second-largest lender said. Branch, ATM and card services were first to recover, while Internet and mobile-based banking, as well as the Velocity business services were later fixed, a spokesperson told Bloomberg in an emailed statement.

In May, DBS Group Holdings Ltd. was slapped with higher capital requirements by the Singapore regulator following a pair of digital banking disruptions.
