In the aftermath of a significant service disruption on October 14, DBS Group (OTC:) Holdings Ltd and Citigroup Inc (NYSE:). are taking measures to enhance their technology risk management systems and controls. The incident saw roughly 810,000 failed attempts by customers to access the banks’ digital platforms, and approximately 2.5 million incomplete payment and ATM transactions in Singapore.
The service outage was pointed out by Alvin Tan, Minister of State for Trade and Industry, in Parliament. He criticized both banks for not meeting the Monetary Authority of Singapore’s (MAS) IT system resilience standards. Despite conducting annual recovery tests at backup data centers, these tests failed to identify the issues that led to the disruption.
In response to the incident, DBS extended its branch hours to assist affected customers. The minister emphasized that banks are directly accountable to their customers, with compensation matters being resolved directly between them.
MAS has instructed both DBS and Citibank to investigate the root causes of the October 14 incidents and implement measures to reduce future disruptions and enhance recovery. DBS, which had five disruptions in the last eight months, is under stricter MAS action. It is prohibited from making non-essential changes or starting new business ventures for six months in order to focus on restoring its digital banking services’ resilience.
Mr. Tan underscored the importance of accountability and remediation measures to ensure reliable banking services. He noted that MAS uses regulatory tools including fines consistent with local penalty regimes to address risk management lapses.
The government is also looking into ways to bolster data center security, which houses not just bank IT systems but also other critical sectors. The minister advised customers to plan for contingencies and have alternative payment options to avoid over-reliance on one provider for time-sensitive transactions. He acknowledged that while the digitalization of financial services brings significant conveniences, financial institutions are expected to recover from any disruption within a reasonable period.
