Bold thought

If ripping out core banking systems were the answer, more banks would have done it by now.

Snapshot

Across global banking, something doesn’t quite add up. Profitability is strong, balance sheets are resilient, and digital ambition is high – but still, frustration with infrastructure is boiling over.

That tension showed up repeatedly in conversations at Money20/20 Middle East 2025. Bank leaders weren’t asking whether legacy cores work, but they were asking why it’s still so hard to launch a product, integrate a partner, or respond to new customer behaviour without months of internal negotiation and technical compromise.

The pressure is coming from multiple directions at once: AI-driven distribution models, faster fintech competitors, and customers increasingly comfortable letting third parties sit between them and their bank. 

According to McKinsey, failure to adapt operating and technology models to this shift could erode up to USD $170 billion of global bank profit pools over the coming decade.

In MENA, the challenge is more intense because banks are strong. IMF analysis shows GCC banks remain well capitalised and resilient – which gives incumbents time to modernise deliberately, but also more to lose if they get it wrong.

Voices

Hatem Ali Hachicha (Expert in Finance Innovation, SVP at a leading bank in the Middle East and Africa):

“Legacy banks don’t need to rebuild their core to move faster… they need to decouple it. By layering modern, API-driven capabilities and partnering with fintechs at the edge, banks can accelerate decision-making and innovation while keeping risk, resilience, and trust anchored in the core.”

What to watch and do

  • Watch: how many banks shift investment away from headline-grabbing core replacements and towards orchestration layers, APIs, and internal platform teams.
  • Do: if you’re inside a bank, ask which parts of your stack are built to change – and which are blocking growth.
  • Do: if you’re a fintech founder, tap into the opportunity in helping institutions modernise – without destabilising the trust they’re built on.
