RBI's deputy governor flags growing reliance on shared cloud and AI vendors as a systemic banking risk.
Reserve Bank of India deputy governor Rohit Jain warned in Mumbai, in remarks reported on September 9, 2026, that Indian banks and financial institutions face rising concentration risk because most depend on a small number of cloud, technology and model providers, according to the Times of India.
Jain's Three Core Concerns
Jain framed his warning around three themes as emerging technologies embed deeper into finance: speed, concentration and opacity, the Times of India reported. He said financial institutions increasingly rely on a narrow set of cloud providers, technology vendors and model providers, often using overlapping datasets and similar infrastructure. This clustering, he cautioned, means the failure of a common provider could become a financial-system problem rather than an isolated institutional failure. Jain added that the core concern is not simply one institution failing, but the possibility that a common dependency could transmit disruption or error across many institutions simultaneously.
The remarks did not detail specific incident scenarios in the reported coverage, but they align with RBI's broader concern that shared technology architecture across banks could allow a single vendor outage or flawed system update to cascade through the wider financial sector.

Part of a Wider RBI Pattern
Jain's comments extend warnings previously voiced by other senior RBI officials. Deputy governor M Rajeshwar Rao had earlier cautioned banks about vendor lock-in, citing a Microsoft cloud outage that disrupted operations at banks and airlines, according to the Times of India. RBI has also flagged Big Tech's expansion into financial services as a governance and stability concern, and its Financial Stability Report has separately identified AI-enabled cyber threats and AI-linked market concentration as top emerging risks facing banks and NBFCs.
RBI issued technology-focused Master Directions on July 31, 2026, setting expectations for governance, cybersecurity and resilience, according to a KPMG summary of the directions. No specific new policy measure was announced alongside Jain's Mumbai remarks, but the speech reinforces a consistent institutional message from RBI leadership urging banks to reduce dependence on shared vendors and strengthen oversight of automated and AI-driven systems.
