Digital banking platforms are increasingly becoming the new anchor to modern banking, providing the technology backbone for both conventional and Islamic banks to compete and grow in an increasingly digital marketplace. Statistics show that the global market for these platforms, valued at USD 12.94 billion in 2024 and projected to reach USD 39.6 billion by 2033, is expanding at 13.23% annually – a clear signal that banking infrastructure, from core banking systems to customer-facing channels, is undergoing a fundamental shift.
Global Digital Banking Platform Market:
But the pressure isn’t just from technology itself; it’s from every direction. Customers expect more, faster, and without friction. FinTechs are releasing products at a pace that makes annual product roadmaps look outdated before they launch. Regulators, once predictable, now move in step with emerging risks, forcing banks to adapt with the same speed as market entrants. In short, the industry’s much-discussed “dynamism” isn’t a trend to admire from afar; it is a reality that punishes hesitation.
In this blog, we take a closer look at banking platforms – where they’ve come from and the pressing case for core modernization, with a focus on Islamic core banking – through the lens of our Digibanc banking platform, which continues to power many banks with both conventional and Islamic cores.
What is a Banking Platform?
A banking platform is a complete technology stack that is comprised of all the components a bank needs to operate internally and serve its customers externally. At its foundation is the core banking system, which handles essential functions such as account management, deposits, withdrawals, and transaction processing. Built around this are additional products and systems that support lending, payments, card issuing, digital channels (mobile and internet banking), treasury management, compliance, fraud prevention, customer onboarding, analytics, and more. These components together form an integrated environment that allows a bank to deliver services seamlessly, manage risk, meet regulatory requirements, and scale as its customer base grows.
Digibanc is an example of such a platform, designed to provide banks with a full spectrum of capabilities within a unified technology backbone. Developed by Codebase Technologies, Digibanc offers a broad stack of products that can be implemented as needed, whether a bank is looking to modernize its core, implement Islamic core banking, launch new lending services, expand its payments network, enable digital onboarding, or offer other Shariah-compliant products. This enables banks to build new products, launch digital banks, and adapt to market changes with speed – all through a plug-and-play model, without reinventing the wheel.
The Evolution of the Banking Platforms
Banking platforms trace their origins to early mainframe-based systems used by institutions like Bank of America in the 1960s, such as the ERMA (Electronic Recording Machine, Accounting) system, which automated check processing and ledger updates, laying the groundwork for computerized banking operations. By the 1970s and 1980s, core banking technology had matured on platforms like Midas, deployed widely across global banks to support transaction processing and back‑office functions, albeit in siloed and batch‑oriented environments.
In the 1980s and 1990s, the shift to client‑server architectures brought performance and usability improvements. These systems introduced GUIs for bank staff and began supporting real-time transactions. The growing internet era then ushered in early digital banking: online portals and ATMs enabled basic services such as balance inquiry and fund transfer anytime, from anywhere. During the 2000s, banks began layering mobile banking, digital onboarding, and e‑commerce capabilities over their core platforms, although innovation remained limited by monolithic architectures.
From the mid-2010s to today, banking platforms evolved into fully integrated ecosystems. Core systems transitioned to cloud-native, API-first, microservices-based architectures built for real-time processing, flexibility, and fintech collaboration. Regulatory shifts and open banking frameworks further accelerated this change, enabling banks to expose services to third-party developers and embed financial products in broader platforms.
We are now seeing banking platforms implement artificial intelligence, machine learning, deep learning for predictive analytics, blockchain for secure and transparent transactions, and robotic process automation – extending these capabilities as deep into the banking technology stack as the core banking level.
Why Banks Need Modern Core Banking Systems
Banks know they need modern banking infrastructure. They need speed to compete, flexibility to innovate, and the agility to keep pace with shifting regulatory and customer demands. However, legacy systems remain their biggest setback. In fact, 55% of banks say core banking technology is their primary hurdle to achieving their business objectives. When you have a legacy core, there’s only so much you can do. New products, integration, or compliance requirements become costly workarounds rather than strategic steps forward.
Below are the key reasons why banks need modern core banking systems.
1. Legacy systems block digital transformation
Legacy core banking systems were built for stability, not adaptability. They rely on rigid architectures that struggle to connect with modern applications, often creating data silos and slowing down operations. More than half of banks still operating on legacy cores – about 53% – report difficulty scaling because of these silos and production bottlenecks. This not only restricts how quickly they can roll out new products or services, but also limits their ability to meet rising customer expectations for speed and personalization.
The industry understands the urgency of moving away from outdated cores. In one recent survey, 93% of banking leaders agreed that their institution’s future success depends on selecting the right core banking solution. Only 2% of respondents said they have no plans to retire their legacy core systems. The message is clear: keeping an old core is no longer a neutral decision; it’s an active choice to accept slower growth, reduced innovation, and declining market relevance.
2. Maintenance costs drain resources
Legacy core systems are expensive to keep running. They require constant patching, specialized skills, and ongoing hardware upkeep, costs that consume a disproportionate share of a bank’s IT budget. Research shows that banks can spend up to 70% of their technology budgets just maintaining legacy infrastructure, leaving only a fraction available for innovation, product development, or strategic initiatives. This imbalance slows down transformation projects and forces banks to choose between keeping the lights on and staying competitive.
The reliance on outdated programming languages and aging infrastructure compounds the problem. Skilled professionals who can support older systems are increasingly scarce, and the cost of retaining them continues to climb. This means that every year spent on a legacy core not only drains financial resources but also deepens the bank’s dependence on a shrinking talent pool, making modernization a matter of long-term viability, not just short-term efficiency.
3. Delayed product launches stifle innovation
In a market where fintech challengers can launch new offerings in weeks, banks tied to legacy cores face product timelines measured in months, and sometimes more than a year. Industry data shows that launching a new product on an outdated core can take anywhere from 6 to 18 months, compared with 3 to 6 months on a modern core. This lag makes it nearly impossible to respond quickly to customer demands, competitive threats, or sudden regulatory changes. Opportunities pass by, and market share shifts to faster, more agile competitors.
The problem is structural. Legacy systems were not built to support rapid development cycles or seamless integration with new technologies. Each new feature or channel often requires complex custom coding, lengthy testing, and manual intervention. In contrast, modern core banking systems are designed with flexible architectures, standardized integration points, and automation capabilities, enabling banks to roll out products faster, adapt to changing requirements, and innovate without the bottlenecks that slow legacy platforms.
4. Need to meet customer expectations for seamless digital experiences
Today’s customers want digital banking experiences as seamless as the ecosystems they live in – social media, streaming platforms, e-commerce, and other instant, personalized services. Failure to meet these expectations has real consequences: 47% of customers say poor digital experience is a top reason for switching banks. Legacy core systems make it difficult to deliver the speed, personalization, and ease customers expect, creating friction in what should be effortless interactions.
Better customer experience directly drives revenue. Research shows that 67% of customers spend more with companies that deliver great experiences, and 85% will switch brands after repeated bad experiences. Positive experiences also create powerful advocacy, with 60% of customers actively recommending brands based on satisfaction. Without the ability to innovate quickly, banks risk losing customers, revenue, and market relevance. Modern core banking systems provide the agility and integration needed to meet these expectations, protecting both customer loyalty and profitability.
5. Support integration with fintech and open banking ecosystems
Modern core banking systems, built on API-first architectures, enable seamless integration with fintechs and open banking platforms, capabilities legacy systems cannot match. This level of connectivity allows banks to adopt new technologies quickly, expand their product offerings, and collaborate with third-party innovators without the cost and delays of custom development. Breaking down legacy data silos also means banks can feed consolidated information into advanced analytics and AI, enabling personalized customer experiences, proactive risk management, and real-time decision-making.
6. Enhance security and regulatory compliance
Modern core banking systems strengthen security and simplify regulatory compliance through real-time monitoring, automated reporting, and built‑in controls aligned with industry standards. They are designed to adapt quickly to evolving regulations, integrate advanced fraud detection and cybersecurity tools, and provide a single source of truth for audit and compliance teams. This reduces the risk of breaches, penalties, and operational disruptions while giving regulators and customers confidence in the bank’s ability to safeguard data and transactions.

The Way Forward: Core Banking Modernization Approaches
Modernizing the core today is no longer a matter of competitive advantage; it is essential for survival. McKinsey estimates that only around half of banks globally generate returns above their Cost of Equity, with the rest falling behind due to structural inefficiencies and slow adaptation. Core banking modernization is one of the most direct levers to improve revenue growth, operational efficiency, and product speed-to-market.
There are three primary paths banks can take when modernizing their core, each with its own balance of risk, investment, and speed of transformation. The choice depends on factors such as the bank’s current technology landscape, regulatory environment, and long-term strategic priorities.
- Progressive Modernization: A phased upgrade strategy where new core components are introduced alongside existing legacy systems. About 40% of global banks take this route to reduce transformation risk while steadily replacing outdated functions. This approach delivers incremental improvements, allowing banks to realize benefits early without the disruption of a full-scale replacement.
- Total Replacement: A complete migration to a new core platform when existing systems are a critical barrier to growth, flexibility, or compliance. Only around 13% of banks pursue this option, trading higher initial investment for a clean slate that enables immediate adoption of modern capabilities.
- Hybrid Modernization: A blended model that retains select legacy functions while adding modular, cloud-based upgrades. This approach can lower infrastructure costs and enable faster rollout of new features, giving banks agility without a full system overhaul.
Whether conventional or Islamic, Digibanc supports all three modernization approaches. Its composable architecture allows banks to phase in capabilities progressively, execute a full core replacement, or implement a hybrid model that combines legacy stability with modern flexibility.

Conclusion
The banking industry stands at a pivotal moment. Market dynamics, regulatory demands, and customer expectations are moving faster than many institutions can keep up with, and the difference between those that lead and those that fall behind increasingly comes down to the strength of their core banking infrastructure. Modern platforms are no longer a competitive advantage. They are the foundation for agility, innovation, and sustained relevance.
Banks relying on legacy cores are already facing mounting costs, longer product cycles, and a shrinking competitive advantage – and these pressures will only intensify over time. Those that embrace modernization will gain the ability to launch faster, integrate seamlessly with fintech ecosystems, deliver exceptional customer experiences, and meet dynamic compliance requirements without disruption.
