MAS, banks test quantum key distribution to strengthen financial cybersecurity

It can securely transfer sensitive data.

The Monetary Authority of Singapore (MAS), together with DBS, HSBC, OCBC, UOB, SPTel, and SpeQtral, has completed a proof-of-concept sandbox testing quantum key distribution (QKD) for secure financial communications.

The initiative follows a memorandum of understanding signed in August 2024 to explore quantum-safe technologies in financial services.

The sandbox validated that QKD can securely transfer sensitive data and highlighted its potential to protect communication networks, including connections between data centres and bank premises.

The exercise also identified areas needing improvement, such as stronger security standards, better interoperability between QKD providers, and the need for senior management support and dedicated resources for quantum-safe initiatives.

MAS Chief Technology Officer Vincent Loy said, “The QKD sandbox is a major step in testing quantum-safe solutions. The insights gained help strengthen Singapore’s financial sector against future cybersecurity threats from quantum computing.”

A NOTE FROM SINGAPORE BUSINESS REVIEW

Reaching the people who run Asia's businesses is harder than it used to be.

Inboxes are crowded. Attention is short. The executives you most want to reach — the founders, CFOs, and operators who actually move budgets — are the hardest to find through the usual channels. If you're building a company, a category, or a reputation, you already know this.

We've spent twenty years building the room they read. Singapore Business Review is where senior decision makers in Singapore and across Southeast Asia come for business coverage they can't get elsewhere — in print, online, and in person at the summits and roundtables we host across seven markets.

If you have something these readers should know about — a point of view worth publishing, a product worth their attention, an event worth their time — we'd like to hear what you're trying to do.
