MAS Chief Warns AI Investment Boom Could Trigger Global Financial Stability Risks

Singapore's central bank has stepped into a growing global debate about whether the artificial intelligence investment boom is sustainable — and the answer, for now, is that nobody really knows. Speaking at the release of MAS's annual report on Tuesday, managing director Chia Der Jiun laid out a sobering two-scenario framework that every investor, tech executive, and policymaker in Singapore should pay attention to.

Chia warned that global growth, investment, and financial market performance have become dangerously dependent on projections of large and increasing spending in data centres and semiconductor chips, especially in the US and semiconductor-exporting Asian economies. If the AI investment boom continues — powered by accelerating revenue growth and broadening productivity gains — it will feed into income, demand, and inflation, affecting how central banks set interest rates. But if the boom cuts short, the fallout could be sharp: a fall in business investment and semiconductor demand, negative wealth effects, and a swift tightening of global financial conditions as equity, credit, and loan markets reprice unsustainable business models.

"Given the high growth that we've experienced, it can be quite a sharp turn, and that can be quite damaging to growth and damaging to financial markets," Chia said. His remarks come at a time when markets are increasingly scrutinising whether the massive capital deployed into AI infrastructure will translate into commercial revenue growth. The key test, he noted, is whether early signs of AI productivity gains at the firm level broaden across the economy and deepen into transformative applications.

On the same day, MAS and the Association of Banks in Singapore announced the AI-Driven Cyber and Technology Risk Taskforce, bringing together DBS, OCBC, UOB, the Singapore Exchange, Nets, and Banking Computer Services. The task force aims to strengthen collective resilience against frontier AI and quantum computing threats — including personalised phishing at scale, deep-fake impersonation, and automated vulnerability exploitation. Chia also flagged quantum computing as a medium-term risk to financial data security and confirmed MAS will issue supervisory expectations later this year with clear milestones for financial institutions to build resilience as they migrate toward quantum-safe systems.

Why it matters for Singapore: As a global financial hub whose portfolio is deeply tied to semiconductor-driven Asian economies and US tech markets, Singapore is uniquely exposed to both sides of the AI investment equation. MAS's dual move — warning about macro risks while simultaneously building industry-level defences — signals that the regulator sees AI not just as a technological opportunity but as a systemic factor that now demands central-bank attention. For anyone watching Singapore's financial sector, the message is clear: AI is no longer just a tech story, it's a macro story.
