Speaking at the Global Fintech Fest 2026, Jain said deeper use of technology can improve banking but also amplify familiar risks. A limited error can spread rapidly across the financial system, leaving little time for people to intervene.

On speed, he pointed to automated systems that process information and act faster than bank officers can respond. Building resilience therefore requires more than trying to prevent every mistake: banks need to spot trouble promptly and contain it before it becomes larger.

Concentration creates another vulnerability when several banks rely on the same small group of technology or cloud providers. A disruption at one shared supplier could affect multiple institutions together. Opacity adds to the challenge, as complex models can produce decisions that are difficult to explain. Using an outside firm for calculations does not remove a bank's responsibility for the outcome.

Jain also cautioned that technology cannot eliminate borrower defaults or liquidity pressures, while quantum computing could pose future security challenges. He highlighted the difficulty of choosing when to regulate: acting prematurely may discourage innovation, but waiting can allow risky systems to become entrenched. Customer safety and fair treatment must remain central.
