Legacy systems are quietly breaking Islamic banks
31 July 2025
The anticipated growth of the Islamic finance industry cannot be understated. With global Islamic finance assets projected to reach $3.8 trillion in 2025, and up to 2 billion Muslims remaining underserved, Islamic banks are in a unique position to capitalise on opportunities and spearhead the vanguard of the Islamic banking industry's future.
Islamic finance is driven by principles
Islamic banking is founded upon guided moral principles embodied through trust, fairness, transparency, and ethical responsibility.
In a global landscape that is increasingly dependent on the digital foundations upon which it is built, banks cannot expect to uphold those principles through simple governance alone. They must deliver them through technology.
But what happens when ageing technology fails? What should you do when the technology that was once your safeguard is becoming a liability?
The core system that forms part of your foundation is beginning to crack, creating fractures — a disconnect between those principles and your responsibilities towards your customers.
Obviously, it may seem negligent to continue to allow such fractures to manifest, let alone persist. Surprisingly, however, many institutions aren't quite ready to accept the current reality and the challenges it poses.
Those who embrace change sooner rather than later, will have a substantial advantage.
Legacy systems are undermining Islamic banking values
Across the Middle East and Africa (MEA) and Asia-Pacific (APAC) regions, many Islamic banks are struggling with outdated core systems. While the intention to provide Shari'ah-based, inclusive financial services remains clear, their infrastructure is making mere intentions consistently difficult to commit to in practice.
According to a handful of insights in our latest Islamic banking report.
70% of large banks in the Middle East are still running on technology built before smartphones became mainstream, technology that wasn’t even built for this era.
In APAC, a whopping 68% of IT budgets are spent just maintaining these outdated systems, leaving little financial room for any form of innovation or transformation.
So, how does this effectively translate to your customer experience?
Well, over the last 2 years, 76% of complaints in Islamic banking were tied directly to digital failures, outages, login issues, and even billing errors.
These aren't isolated incidents. They're consistent signals that the core systems supporting Islamic banks are no longer fit for purpose. It's a problem that's often invisible on the surface but is silently eroding customer satisfaction, operational agility, and, vitally, that reputational trust at the core of relationships.
