Following the successful deployment of TCS BaNCS for Treasury across Indian Bank's operations in India and at GIFT City in Gujarat, the platform is now being extended to the Bank's Colombo branch, reinforcing a unified approach to treasury operations across geographies. With this expansion, Indian Bank marks a new milestone platform-led transformation with TCS. As part of the collaboration, TCS will help Indian Bank modernize its overseas treasury operations across money markets, investment management, and foreign exchange. The transformation will enable Indian Bank’s Colombo branch to move to a single, integrated treasury platform that supports unified deal processing, real-time position visibility, stronger risk and limit controls, and compliance-ready reporting. The Bank will be able to reduce manual intervention, improve straight-through processing, and strengthen audit and regulatory readiness through a single source of truth. S Viswanathan, CEO, Indian Bank, Sri Lanka Operations, said, “As our treasury operations in Sri Lanka evolve, we need a platform that can support growth with greater control, transparency and operational agility. We are happy that we have chosen TCS BaNCS for Treasury which has already proven its capability for Indian Bank’s India and GIFT City operations. The platform provides us with a modern foundation to address evolving banking requirements. We look forward to working with TCS as we continue to build a more resilient and scalable treasury operation.” Venkateshwaran Srinivasan, Global Head, Financial Solutions, Tata Consultancy Services, said, “Treasury transformation today is about more than automation—it is about enabling banks to operate with speed, insight, and confidence in dynamic market environments. With TCS BaNCS for Treasury, we are proud to support Indian Bank’s overseas business in Sri Lanka with a solution that brings together deep treasury functionality, operational resilience, and regulatory confidence. This partnership reflects TCS’ commitment to helping financial institutions modernize core operations and build future-ready platforms for growth.” With seamless deployment and continued maintenance, TCS will help the bank accelerate time-to-value while ensuring smooth integration with its existing systems and international market infrastructure. For the Bank’s Colombo branch, the platform will provide greater control over foreign exchange and market risk exposures, faster deal execution and settlement cycles, and improved regulatory reporting. It will also support strategic decision-making by giving treasury teams a consolidated view of positions, limits, liquidity, and exposures across instruments and currencies.
