A bank can remain solvent and well-capitalized yet be unable to process customer payments if a shared digital service fails for multiple institutions at once, elevating common technology dependencies to a top global financial-stability concern.

At the IMF–World Bank meetings in Bangkok, officials launched an anti-fraud blueprint amid IMF and FSB warnings on cyber and AI-related risks from concentrated providers of cloud, identity, and payment tools; Europe’s DORA already oversees critical ICT firms while the US has proposed updated third-party guidance, but neither fully addresses simultaneous multi-bank failures.

Regulators are urged to run controlled cross-border exercises that measure “safe-payment throughput”—the volume and value of legitimate payments completed without weakening required controls—after simulated shared-service outages, recognizing that operational disruption can mimic financial distress and that separate bank plans do not guarantee joint resilience.

At the IMF–World Bank meetings in Bangkok, financial leaders are confronting digital fraud. Their next test should be what happens when banks depend on the same broken technology provider.

A bank can be solvent, well capitalized and open for business—and still be unable to process a customer’s payment. Now imagine several banks encountering that problem at once, not because each has suffered a separate attack, but because all depend on the same unavailable technology service.

That is a scenario, not a report of an incident. Yet it belongs near the top of the global financial-stability agenda.

At this week’s IMF–World Bank meetings in Bangkok, officials launched the Bangkok Blueprint for Fraud-Resilient Financial Services, a new framework for fighting cyber-enabled fraud through cooperation across the financial ecosystem. It addresses a genuine threat. But preventing fraudulent payments is not the whole challenge. Financial systems must also prove that they can continue processing legitimate payments when the shared digital services on which banks depend suddenly fail.

The warnings are unusually current. In its October 13 Global Financial Stability Report briefing, the IMF identified cyber incidents capable of disrupting financial services or weakening confidence as a significant source of risk. A day earlier, the Financial Stability Board (FSB) renewed its warning about vulnerabilities connected to artificial intelligence and the increasingly interconnected financial system.

Those statements should lead to a practical question: what would remain safe and functional if several otherwise healthy financial institutions needed the same broken supplier at the same moment?
