Singapore, 23 April 2026 – Cybersecurity threats have emerged as the biggest concern for Tan Su Shan, as the head of Southeast Asia’s largest bank warns that rising digital risks are becoming more pressing than traditional market volatility.
Speaking to CNBC, Tan highlighted that cyberattacks are the issue that keeps her “up at night,” underscoring the growing threat landscape facing financial institutions in an increasingly digital and AI-driven environment.
Cybersecurity Overtakes Traditional Financial Risks
Tan’s remarks reflect a shift in risk priorities within the banking sector.
While macroeconomic factors such as inflation, interest rates and geopolitical tensions remain relevant, cyber threats are now seen as more immediate and potentially disruptive to operations.
Banks are increasingly vulnerable due to:
- Large volumes of sensitive customer data
- Complex digital infrastructure
- Expanding use of AI and automation
This makes cybersecurity not just an IT issue, but a core strategic risk for financial institutions.
AI Accelerating Both Opportunity and Risk
The rise of artificial intelligence is amplifying the cybersecurity challenge.
While AI enhances efficiency and customer experience, it also enables more sophisticated cyberattacks, including automated fraud, phishing and system exploitation.
Tan has previously emphasised that technological transformation is essential for growth, but it must be matched with robust safeguards to prevent vulnerabilities from escalating.
Banking Sector on High Alert
Financial institutions globally are ramping up investments in cybersecurity infrastructure, talent and monitoring systems.
The increasing frequency and sophistication of attacks are forcing banks to:
- Strengthen real-time threat detection
- Enhance customer protection measures
- Improve resilience of digital platforms
For DBS, maintaining trust and system reliability remains central to its strategy as a leading digital bank in Asia.
Leadership Perspective on Risk Management
Tan’s comments highlight a broader leadership challenge, balancing innovation with risk control.
As banks adopt new technologies at speed, executives are required to ensure that governance frameworks, security protocols and operational resilience evolve in tandem.
The growing complexity of cyber threats means that risk management is becoming a board-level priority across the financial sector.
The Ledger Asia Insights
The rising focus on cybersecurity signals a fundamental shift in how risk is perceived in the digital economy.
For Asian investors, three key implications emerge:
1. Cybersecurity Becomes Systemic Risk
Digital threats are now central to financial stability and operational resilience.
2. AI Raises Both Efficiency and Vulnerability
Technological advancement must be matched with stronger security frameworks.
3. Banks Increase Investment in Digital Defence
Cybersecurity spending is set to rise as institutions prioritise protection and trust.
Tan’s warning underscores a new reality for global finance, where the greatest risks are no longer just economic, but digital, evolving rapidly alongside the technologies shaping the future of banking.
