Modernization of legacy systems in banking

Modernization of legacy systems in banking

To compete in the digital age, banks and financial institutions need to become customer- centric, with processes driven by data and powered by open and agile systems.

46% of bankers see the legacy systems as the biggest barriers to the growth of commercial banks.

Everywhere you turn digital innovations are disrupting the marketplace, leaving the legacy systems in banking behind. Today, customers’ expectations and demands from banks have grown multifold and they demand the same kinds of features and services they routinely receive from companies on the leading edge of digital innovation.

It might come as a surprise, but a large number of banks that were started back in the 1970s or even 1980s relied on a few obsolete technologies within their core banking processes. But with time, and the evolving market scenario, the need for digital solutions and agile software architecture has replaced traditional systems. There is constant  development in the  technology space, and today we have  Artificial Intelligence, Machine Learning, Data Analytics, Connected devices, Open APIs morphing into the mainstream business processes.

Since the legacy systems are unable to support the rising expectations and there is a visible slump in revenue, banks and other financial institutions are looking to modernize their systems. The traditional legacy systems also weigh heavily on the overall operational cost and maintenance, combined with the dearth of experts who can resolve issues arising within them. 

The first two orders of business for banks looking to make sweeping changes, according to Deloitte’s 2019 Banking and Capital Markets Outlook, are updates to their digital capabilities and modernization of legacy systems. These two categories alone make up 51% of banks’ focus in the coming year.
