What’s holding your team back from embracing this change?

Define Legacy Systems in Banking

Legacy frameworks in banking are often referred to as banking legacy systems, representing outdated technology platforms that persist within financial institutions, typically constructed with older programming languages and architectures. These frameworks are vital to core banking functions, encompassing transaction processing, customer account management, and compliance reporting. Key features of banking legacy systems include:

• Age: Many banking legacy systems are decades old, leading to significant challenges in maintenance and connection with contemporary technologies.
• Inflexibility: Banking legacy systems often lack the agility necessary to adapt to evolving business requirements or regulatory changes, hindering innovation.
• High Maintenance Costs: The upkeep of banking legacy systems can consume a substantial portion of IT budgets, primarily due to the need for specialized skills and resources.
• Connection Challenges: Operating in silos, banking legacy systems complicate data sharing and interoperability with newer applications, creating barriers to efficient operations.

As of 2025, approximately 70% of banks still rely on banking legacy systems, which exacerbates economic and operational costs. The longer organizations maintain these banking legacy systems, the more pronounced these costs become. Expert opinions emphasize that the incorporation of generative AI can alleviate some of these challenges. For instance, Gustavo Estrada, a customer, noted that Avato simplifies complex projects and delivers results within desired time frames and budget constraints. This combination guarantees thorough testing of new frameworks and automatically produces compliance-related documentation, addressing gaps caused by personnel turnover in the banking sector.

We believe Avato’s hybrid platform empowers businesses to future-proof their operations by seamlessly linking legacy frameworks with modern applications, enhancing data flow and operational efficiency. Case studies illustrate that organizations implementing business process automation strategies can achieve notable improvements in efficiency and agility, leading to enhanced financial outcomes. Particularly, the incorporation of automation in finance has transformed operational workflows, underscoring the pressing requirement for financial institutions to update their banking legacy systems to remain competitive in a swiftly changing environment. Moreover, generative AI aids knowledge transfer by offering thorough documentation, which is essential in tackling the difficulties presented by banking legacy systems.

Recognize the Need for Modernization

The necessity for modernization in banking is underscored by several critical factors:

• Competitive Pressure: Fintech companies and neobanks are leveraging advanced technologies to deliver superior services, compelling traditional banks to modernize their systems to retain customer loyalty. Notably, 22% of executives recognize economic uncertainty as a barrier to executing digital transformations, highlighting the urgency for financial institutions to innovate. Our proficient unification services, encompassing enterprise architecture and project management, can assist financial institutions in navigating these challenges by providing experienced collaboration partners who understand the intricacies of updating outdated frameworks.
• Regulatory Compliance: As regulations become increasingly rigorous, financial institutions must ensure their frameworks can swiftly adapt to new compliance demands. This adaptability is essential for avoiding penalties and maintaining operational integrity. Our hybrid integration platform is designed to simplify this process, enabling financial institutions to meet compliance requirements effectively.
• Operational Efficiency: Operational efficiency is compromised by banking legacy systems, as outdated technologies often lead to inefficiencies, resulting in elevated operational costs and sluggish responses to market dynamics. Many conventional financial institutions struggle to integrate new digital technologies with their banking legacy systems, with over 70% of industry leaders acknowledging the significance of embedded finance, yet only 20% currently offering such solutions. Furthermore, a 2023 survey revealed that 67% of financial institutions cited difficulty in hiring qualified tech talent as a major obstacle to their digital transformation efforts. We address these challenges by providing a specialized hybrid integration platform that streamlines the connection of diverse networks, enhancing operational efficiency.
• Customer Expectations: Today’s consumers demand seamless, digital-first banking experiences. Banking legacy systems often hinder financial institutions’ ability to meet these expectations, making updates essential for customer satisfaction and loyalty. Our client-focused solutions empower financial institutions to connect traditional frameworks with contemporary demands, thereby enhancing B2B customer experiences.

Given these challenges, upgrading banking legacy systems has become a necessity for survival in an increasingly competitive environment, rather than just a choice. As Vikram Bhat, a leader in the financial services sector, emphasizes, “Nurturing talent and adopting innovation are essential for financial institutions to manage these pressures effectively.” Additionally, cloud migration and robust data infrastructure are vital components of core framework enhancement, further supporting operational efficiency and regulatory compliance. Consequently, financial institutions must prioritize these elements to remain competitive.
