Banks, insurers, and other financial services organisations in Asia Pacific have plenty of tech challenges and opportunities including cybersecurity and data privacy management; adapting to tech and customer demands, AI and ML integration; use of big data for personalisation; and regulatory compliance across business functions and transformation journeys.
Modernisation Projects are Back on the Table
An emerging tech challenge lies in modernising, replacing, or retiring legacy platforms and systems. Many banks still rely on outdated core systems, hindering agility, innovation, and personalised customer experiences. Migrating to modern, cloud-based systems presents challenges due to complexity, cost, and potential disruptions. Insurers are evaluating key platforms amid evolving customer needs and business models; ERP and HCM systems are up for renewal; data warehouses are transforming for the AI era; even CRM and other CX platforms are being modernised as older customer data stores and models become obsolete.
For the past five years, many financial services organisations in the region have sidelined large legacy modernisation projects, opting instead to make incremental transformations around their core systems. However, it is becoming critical for them to take action to secure their long-term survival and success.
Benefits of legacy modernisation include:
- Improved operational efficiency and agility
- Enhanced customer experience and satisfaction
- Increased innovation and competitive advantage
- Reduced security risks and compliance costs
- Preparation for future technologies
However, legacy modernisation and migration initiatives carry significant risks. For instance, TSB faced a USD 62M fine due to a failed mainframe migration, resulting in severe disruptions to branch operations and core banking functions like telephone, online, and mobile banking. The migration failure led to 225,492 complaints between 2018 and 2019, affecting all 550 branches and required TSB to pay more than USD 25M to customers through a redress program.
Modernisation Options
- Rip and Replace. Replacing the entire legacy system with a modern, cloud-based solution. While offering a clean slate and faster time to value, it’s expensive, disruptive, and carries migration risks.
- Refactoring. Rewriting key components of the legacy system with modern languages and architectures. It’s less disruptive than rip-and-replace but requires skilled developers and can still be time-consuming.
- Encapsulation. Wrapping the legacy system with a modern API layer, allowing integration with newer applications and tools. It’s quicker and cheaper than other options but doesn’t fully address underlying limitations.
- Microservices-based Modernisation. Breaking down the legacy system into smaller, independent services that can be individually modernised over time. It offers flexibility and agility but requires careful planning and execution.
Financial Systems on the Block for Legacy Modernisation
Data Analytics Platforms. Harnessing customer data for insights and targeted offerings is vital. Legacy data warehouses often struggle with real-time data processing and advanced analytics.
CRM Systems. Effective customer interactions require integrated CRM platforms. Outdated systems might hinder communication, personalisation, and cross-selling opportunities.
Payment Processing Systems. Legacy systems might lack support for real-time secure transactions, mobile payments, and cross-border transactions.
Core Banking Systems (CBS). The central nervous system of any bank, handling account management, transactions, and loan processing. Many Asia Pacific banks rely on aging, monolithic CBS with limited digital capabilities.
Digital Banking Platforms. While several Asia Pacific banks provide basic online banking, genuine digital transformation requires mobile-first apps with features such as instant payments, personalised financial management tools, and seamless third-party service integration.
Modernising Technical Approaches and Architectures
Numerous technical factors need to be addressed during modernisation, with decisions needing to be made upfront. Questions around data migration, testing and QA, change management, data security and development methodology (agile, waterfall or hybrid) need consideration.
Best practices in legacy migration have taught some lessons.
Adopt a data fabric platform. Many organisations find that centralising all data into a single warehouse or platform rarely justifies the time and effort invested. Businesses continually generate new data, adding sources, and updating systems. Managing data where it resides might seem complex initially. However, in the mid to longer term, this approach offers clearer benefits as it reduces the likelihood of data discrepancies, obsolescence, and governance challenges.
Focus modernisation on the customer metrics and journeys that matter. Legacy modernisation need not be an all-or-nothing initiative. While systems like mainframes may require complete replacement, even some mainframe-based software can be partially modernised to enable services for external applications and processes. Assess the potential of modernising components of existing systems rather than opting for a complete overhaul of legacy applications.
Embrace the cloud and SaaS. With the growing network of hyperscaler cloud locations and data centres, there’s likely to be a solution that enables organisations to operate in the cloud while meeting data residency requirements. Even if not available now, it could align with the timeline of a multi-year legacy modernisation project. Whenever feasible, prioritise SaaS over cloud-hosted applications to streamline management, reduce overhead, and mitigate risk.
Build for customisation for local and regional needs. Many legacy applications are highly customised, leading to inflexibility, high management costs, and complexity in integration. Today, software providers advocate minimising configuration and customisation, opting for “out-of-the-box” solutions with room for localisation. The operations in different countries may require reconfiguration due to varying regulations and competitive pressures. Architecting applications to isolate these configurations simplifies system management, facilitating continuous improvement as new services are introduced by platform providers or ISV partners.
Explore the opportunity for emerging technologies. Emerging technologies, notably AI, can significantly enhance the speed and value of new systems. In the near future, AI will automate much of the work in data migration and systems integration, reducing the need for human involvement. When humans are required, low-code or no-code tools can expedite development. Private 5G services may eliminate the need for new network builds in branches or offices. AIOps and Observability can improve system uptime at lower costs. Considering these capabilities in platform decisions and understanding the ecosystem of partners and providers can accelerate modernisation journeys and deliver value faster.
Don’t Let Analysis Paralysis Slow Down Your Journey!
Yes, there are a lot of decisions that need to be made; and yes, there is much at stake if things go wrong! However, there’s a greater risk in not taking action. Maintaining a laser-focus on the customer and business outcomes that need to be achieved will help align many decisions. Keeping the customer experience as the guiding light ensures organisations are always moving in the right direction.
When the FinTech revolution started, traditional banking felt the heat of competition from the ‘new kid on the block’. FinTechs promised (and often delivered) fast turnarounds and personalised services. Banks were forced to look at their operations through the lens of customer experience, constantly re-evaluating risk exposures to compete with FinTechs.
But traditional banks are giving their ‘neo-competitors’ a run for their money. Many have transformed their core banking for operational efficiency. They have also taken lessons from FinTechs and are actively working on their customer engagements. This Ecosystm Snapshot looks at how banks (such as Standard Chartered Bank, ANZ Bank, Westpac, Commonwealth Bank of Australia, Timo, and Welcome Bank) are investing in tech-led transformation and the ways tech vendors (such as IBM, Temenos, Mambu, TCS and Wipro) are empowering them.

In this Insight, guest author Anupam Verma talks about the technology-led evolution of the Banking industry in India and offers Cloud Service Providers guidance on how to partner with banks and financial institutions. “It is well understood that the banks that were early adopters of cloud have clearly gained market share during COVID-19. Banks are keen to adopt cloud but need a partnership approach balancing innovation with risk management so that it is ‘not one step forward and two steps back’ for them.”
India has been witnessing a digital revolution. Rapidly rising mobile and internet penetration has created an estimated 1 billion mobile users and more than 600 million internet users. It has been reported that 99% of India’s adult population now has a digital identity in the form of Aadhar and a large proportion of the adult Indians have a bank account.
Indians are adapting to consume multiple services on the smartphone and are demanding the same from their financial services providers. COVID-19 has accelerated this digital trend beyond imagination and is transforming India from a data-poor to a data-rich nation. This data from various alternate sources coupled with traditional sources is the inflection point to the road to financial inclusion. Strong digital infrastructure and digital footprints will create a world of opportunities for incumbent banks, non-banks as well as new-age fintechs.
The Cloud Imperative for Banks
Banks today have an urgent need to stay relevant in the era of digitally savvy customers and rising fintechs. This journey for banks to survive and thrive will put Data Analytics and Cloud at the front and centre of their digital transformation.
A couple of years ago, banks viewed cloud as an outsourcing infrastructure to improve the cost curve. Today, banks are convinced that cloud provides many more advantages (Figure 1).
Banks are also increasingly partnering with fintechs for applications such as KYC, UI/UX and customer service. Fintechs are cloud-native and understand that cloud provides exponential innovation, speed to market, scalability, resilience, a better cost curve and security. They understand their business will not exist or reach scale if not for cloud. These bank-fintech partnerships are also making banks understand the cloud imperative.
Traditionally, banks in India have had concerns around data privacy and data sovereignty. There are also risks around migrating legacy systems, which are made of monolithic applications and do not have a service-oriented architecture. As a result, banks are now working on complete re-architecture of the core legacy systems. Banks are creating web services on top of legacy systems, which can talk to the new technologies. New applications being built are cloud ready. In fact, many applications may not connect to the core legacy systems. They are exploring moving customer interfaces, CRM applications and internal workflows to the cloud. Still early days, but banks are using cloud analytics for marketing campaigns, risk modelling and regulatory reporting.
The remote working world is irreversible, and banks also understand that cloud will form the backbone for internal communication, virtual desktops, and virtual collaboration.
Strategy for Cloud Service Providers (CSPs)
It is estimated that India’s public cloud services market is likely to become the largest market in the Asia Pacific behind only China, Australia, and Japan. Ecosystm research shows that 70% of banking organisations in India are looking to increase their cloud spending. Whichever way one looks at it, cloud is likely to remain a large and growing market. The Financial Services industry will be one of the prominent segments and should remain a focus for cloud service providers (CSPs).
I believe CSPs targeting India’s Banking industry should bucket their strategy under four key themes:
- Partnering to Innovate and co-create solutions. CSPs must work with each business within the bank and re-imagine customer journeys and process workflow. This would mean banking domain experts and engineering teams of CSPs working with relevant teams within the bank. For some customer journeys, the teams have to go back to first principles and start from scratch i.e the financial need of the customer and how it is being re-imagined and fulfilled in a digital world.
CSPs should also continue to engage with all ecosystem partners of banks to co-create cloud-native solutions. These partners could range from fintechs to vendors for HR, Finance, business reporting, regulatory reporting, data providers (which feeds into analytics engine).
CSPs should partner with banks for experimentation by providing test environments. Some of the themes that are critical for banks right now are CRM, workspace virtualisation and collaboration tools. CSPs could leverage these themes to open the doors. API banking is another area for co-creating solutions. Core systems cannot be ‘lifted & shifted’ to the cloud. That would be the last mile in the digital transformation journey. - Partnering to mitigate ‘fear of the unknown’. As in the case of any key strategic shift, the tone of the executive management is important. A lot of engagement is required with the entire senior management team to build the ‘trust quotient’ of cloud. Understanding the benefits, risks, controls and the concept of ‘shared responsibility’ is important. I am an AWS Certified Cloud Practitioner and I realise how granular the security in the cloud can be (which is the responsibility of the bank and not of the CSP). This knowledge gap can be massive for smaller banks due to the non-availability of talent. If security in the cloud is not managed well, there is an immense risk to the banks.
- Partnering for Risk Mitigation. Regulators will expect banks to treat CSPs like any other outsourcing service providers. CSPs should work with banks to create robust cloud governance frameworks for mitigating cloud-related risks such as resiliency, cybersecurity etc. Adequate communication is required to showcase the controls around data privacy (data at rest and transit), data sovereignty, geographic diversity of Availability Zones (to mitigate risks around natural calamities like floods) and Disaster Recovery (DR) site.
- Partnering with Regulators. Building regulatory comfort is an equally important factor for the pace and extent of technology adoption in Financial Services. The regulators expect the banks to have a governance framework, detailed policies and operating guidelines covering assessment, contractual consideration, audit, inspection, change management, cybersecurity, exit plan etc. While partnering with regulators on creating the framework is important, it is equally important to demonstrate that banks have the skill sets to run the cloud and manage the risks. Engagement should also be linked to specific use cases which allow banks to effectively compete with fintech’s in the digital world (and expand financial access) and use cases for risk mitigation and fraud management. This would meet the regulator’s dual objective of market development as well as market stability.
Financial Services is a large and growing market for CSPs. Fintechs are cloud-native and certain sectors in the industry (like non-banks and insurance companies) have made progress in cloud adoption. It is well understood that the banks that were early adopters of cloud have clearly gained market share during COVID-19. Banks are keen to adopt cloud but need a partnership approach balancing innovation with risk management so that it is ‘not one step forward and two steps back’ for them.
