Core banking is mid-sized banks’ greatest handicap. Thousands of smaller banks are stuck on outdated infrastructure. And yet very few players are paying attention to this multi-billion gap.
 
𝗖𝗼𝗿𝗲 𝗯𝗮𝗻𝗸𝗶𝗻𝗴: 
 
• Core banking systems are back-end software that banks use to manage their most critical processes, from transactions to accounts and to all kinds of day-to-day operational needs.
 
• Originally developed in the 1960s and 1970s, they are instrumental for banks: they influence costs, time-to-market, operational efficiency, and product sophistication. In essence the ability to innovate.
 
• Initially seen as the banks’ competitive edge, they have gradually turned into a handicap as their performance and sophistication can no longer match the needs of a digital world and competition from challenger players.
 
Today, core banking transformation is the jargon used by banks to modernize their infrastructure. Three shifts stand out:
 
1)   The move from in-house systems to the cloud
2)   The adoption of open, modular microservices (breaking the core into small, independent building blocks)
3)   AI as a foundational layer
 
𝗠𝗶𝗱-𝘀𝗶𝘇𝗲𝗱 𝗯𝗮𝗻𝗸𝘀: 
 
For the largest banks, transformation is a multi-billion, multi-year journey. At the other end, fintechs can build greenfield platforms. Small and mid-sized banks sit in between: too complex to rely on lightweight fintech platforms, too small to justify the cost and risk of mega-projects.
 
What smaller banks need instead:
 
• Modular cores they can adopt step-by-step
• OPEX-friendly delivery with fast payback, vs heavy upfront CAPEX with delayed value.
• Real ecosystems: APIs, partners, and embedded finance options out of the box.
 
𝗧𝗿𝗲𝗻𝗱𝘀:  
 
That gap is both smaller banks’ main pain point and the industry’s biggest opportunity.
 
And specialised players are stepping in.
 
Natech is a good example. It has long served regional banks with reliable core systems, but with its recent funding round it aims to become the go-to choice for mid-sized banks and FIs.
 
The playbook is absolutely spot-on and shows what the industry should be doing:
 
• Leverage AI to give smaller banks the same advanced capabilities their largest peers have enjoyed — out of the box and in a way they can roll out incrementally and affordably: mass personalization on the distribution side, smarter credit decisioning, real-time fraud detection, and automated compliance and reporting — all without multi-million IT budgets.
 
• Growth for mid-sized banks has long been confined to their own branches and apps. Natech’s API-first, cloud-native core unlocks embedded finance — allowing banks to distribute payments, lending, and deposits directly through retailers, fintechs, and digital platforms.
 
The next generation of core banking transformation will increasingly be customized and segment specific.
