How to improve efficiency: An integrated approach to transforming organizations in the banking sector

In an environment marked by pressure on margins, increasingly high customer expectations, and rising regulatory requirements, operational efficiency has become a strategic priority for the banking sector. Reducing the cost-to-income ratio remains a central goal, but approaches based solely on cost-cutting tend to yield limited results that are difficult to sustain.

Improving operational efficiency in banks requires a deeper transformation of the operation. This means simplifying processes, eliminating non-value-added activities, improving resource use, strengthening end-to-end accountability, and using technology to accelerate already redesigned operations. Simultaneously, it is essential to maintain quality, compliance, and the customer experience.

The most efficient organizations do not approach productivity, digitization, and cost reduction in the banking sector as isolated initiatives. They develop an integrated vision that combines operational excellence, team development, organizational agility, innovation, and customer centricity. It is this systematic approach that makes it possible to increase productivity sustainably and turn efficiency into a real competitive advantage.

What is operational efficiency in banking?

Operational efficiency is often associated with cost-cutting strategies in the banking sector, such as closing service counters or reducing the number of employees. However, being operationally efficient means making the best use of the available resources to deliver more value, faster, with more quality and more predictability. This means eliminating non-value-added activities, reducing rework and waiting time, simplifying processes, improving coordination between departments, and ensuring clear accountability throughout the entire flow. The goal is not just to do the same with fewer resources, but to rethink how the work is done.

This approach is especially relevant in a sector in which efficiency must coexist with high standards of compliance, safety, and service quality. A truly efficient operation can meet regulatory requirements and customer expectations without adding unnecessary complexity. Therefore, the reduction in the cost-to-income ratio should be seen as the result of a broader transformation, rather than an isolated cost-control goal.

Indicators for assessing a bank’s efficiency

Assessing a bank’s efficiency requires combining financial indicators with metrics that reveal how the operation actually works. Aggregate ratios make it possible to compare performance over time and against other institutions, but they do not, on their own, explain where inefficiencies lie or which actions are needed to eliminate them.

A cost reduction can temporarily improve financial indicators, even when processes remain fragmented, response times remain high, or teams face a growing volume of rework. Therefore, banks need to supplement the financial overview with a detailed analysis of productivity, quality, speed, and customer experience.

Cost-to-income ratio or banking efficiency ratio

The cost-to-income ratio, also referred to in some cases as the bank efficiency ratio, is one of the most widely used indicators for assessing cost efficiency in banking. It compares operating costs with net operating profits and indicates the percentage of the profits absorbed by the organization’s operations:

Cost-to-income ratio = Operating costs ÷ Net operating profit × 100

The lower the ratio, the smaller the profit proportion needed to support the operational structure. Its progress allows banks to assess whether they are increasing profits faster than costs and whether their transformation initiatives are having a financial impact.

The designation and components used in the calculation can vary between institutions. In some cases, the indicator considers operating costs relative to operating income; in others, it uses non-interest expenses and different income components. For this reason, any comparison should ensure that the same accounting criteria, analysis periods, and income and cost components are applied.

Despite its relevance, the indicator should be interpreted with caution. Its improvement may result from a one-off increase in income, accounting changes, or cost reductions that do not structurally transform the operation. In addition, a positive aggregate result can mask significant differences between areas, coexisting with critical processes that are slow, costly, or excessively manual.

Operational performance beyond financial indicators

To understand the causes that affect financial performance, it is necessary to look at the processes that drive it. This involves tracking operational indicators at the level of the main value streams, such as account opening, credit granting, payment processing, complaint management, or compliance with know-your-customer requirements.

Productivity should be assessed based on the volume processed per employee or per unit of time, but always together with quality. An increase in the number of completed transactions will have little value if it is accompanied by more errors, rework, non-compliance, or additional customer contacts.

The lead time reveals the total time elapsed between the request and the completion of a service. It should be analyzed together with actual execution time, since a significant part of that time may result from waiting, transfers between areas, successive approvals, or missing information. This distinction makes it possible to identify opportunities that would not be visible through financial indicators.

Other relevant metrics include first-contact resolution, the percentage of processes completed correctly the first time, service-level compliance, cost per transaction, the degree of automation, customer satisfaction, and complaint volume. Capacity utilization, workload distribution, and team versatility also help show whether resources are aligned with demand.

Efficiency becomes visible when financial and operational results evolve consistently. This is the vision behind KAIZEN™ in banking: lower costs, faster processes, fewer errors, better use of resources, and a superior customer experience.

Why it is difficult to improve operational efficiency in banking

Improving operational efficiency in banking is particularly difficult because processes span across multiple areas, channels, and systems, under strict regulatory requirements. Even when each team optimizes its own part of the process, overall performance can still be limited by handoffs, successive approvals, task duplication, missing information, and a lack of end-to-end accountability.

Depending on outdated or poorly integrated technology systems adds to this complexity. Many teams continue to switch between different applications, re-enter data, and rely on spreadsheets or manual controls. At the same time, new regulatory requirements are frequently added to existing processes without an overall redesign, building up validations, exceptions, and control points.

In this context, banking process automation, including back-office automation, often emerges as the most immediate response, together with artificial intelligence and digital platforms. These solutions can increase productivity, reduce errors, and speed up processing. However, when applied to fragmented processes, they often end up simply digitizing existing waste. For this reason, before automating, it is necessary to simplify processes, eliminate non-value-added activities, reduce exceptions, clarify responsibilities, and improve workflow.

Only then can technology function as a true accelerator of operational efficiency and contribute sustainably to reducing the cost-to-income ratio.

How to improve operational efficiency in banks: An integrated approach to transforming organizations in the financial sector

Improving operational efficiency in banking should not be treated as an isolated initiative. The most sustainable results emerge when the transformation brings together the customer experience, organizational performance, technology, and sustainability. These dimensions are interconnected: simpler processes reduce costs and improve service; more skilled teams solve problems faster; and technology amplifies the benefits when applied to operations that have already been optimized.

An integrated approach therefore makes it possible to act across several complementary areas: customer experience, organization and management of teams and processes, and innovation and sustainability. Together, these dimensions make it possible to improve quality, reduce costs, accelerate delivery, promote growth, and strengthen the organization’s impact.

Excellence in customer experience

Improving customer experience in banking starts by reducing the need for contact and resolving requests at the first point of interaction. This requires analyzing the reasons for contact, eliminating their causes, improving the quality of the information provided, and routing each request to the most appropriate channel. The transition to digital or asynchronous channels should increase convenience and speed without compromising human support at moments when it adds value.

On the commercial side, improvement involves better understanding the needs of each segment and using data to personalize products, offers, and interactions. An omnichannel strategy should ensure consistent experience across branches, contact centers, apps, and digital channels. In this context, the transformation of the branch network must redefine the role of branches, freeing teams from administrative tasks, increasing branch productivity, and strengthening their ability to provide advice and develop customer relationships.

At the same time, the sales force must have the skills, data, and tools needed to identify relevant cross-selling and upselling opportunities. The goal is not just to increase conversion rates but to build relationships better suited to each customer’s profile and moment, improving growth and satisfaction at the same time.

Organizational excellence

Operational excellence in banking begins with creating flow in processes and using resources efficiently. This means standardizing ways of working, eliminating non-value-added tasks, reducing handoffs and waiting, ensuring that work is done right the first time, and establishing clear accountability throughout the entire process. Resource efficiency should be analyzed in parallel, balancing capacity with demand and freeing up teams from administrative or repetitive tasks.

This transformation also requires a management model that connects strategic objectives to daily work. Teams need clear indicators, follow-up routines, mechanisms for reacting to deviations, and structured problem-solving processes. Leaders should spend less time firefighting and more time developing people, improving performance, and removing obstacles.

Organizational agility complements this vision. Less hierarchical structures, multidisciplinary teams, and greater autonomy enable faster decision-making and the faster implementation of new solutions. However, autonomy must be accompanied by clear priorities, defined responsibilities, and metrics that ensure alignment with the organization’s goals.

Innovation and sustainability

Digital transformation should be seen as a catalyst for improvement. Automating repetitive tasks, digital management of workflows and work queues, data integration, and advanced analytics can increase productivity, reduce waiting times, and support faster decisions.

In this context, data also plays a central role in creating new products, anticipating trends, assessing risk, and personalizing the customer experience. To generate value, it is necessary to ensure the quality and integration of information, define priority use cases, and develop teams’ skills to work with new technologies and analytical models.

In turn, sustainability should cover internal operations, the product portfolio, and the value chain. This includes reducing the organization’s own environmental and social impact, ensuring compliance with ESG requirements, developing sustainable financial solutions, and helping customers, partners, and suppliers adopt best practices. In this way, sustainability stops being just a regulatory obligation and starts contributing to differentiation, risk management, and long-term value creation.

How to turn the vision for improvement into operational results

An integrated vision only creates impact when it is translated into a clear implementation plan and carried out with the teams. The transformation should start with the processes and areas that have the greatest influence on strategic objectives, focusing resources where there is the greatest potential to improve service, productivity, quality, and costs.

More than launching isolated initiatives, lean management in banking requires a structured approach that connects diagnosis to implementation, involves the people who do the work, and tracks the benefits over time.

Analyze the current state and develop a future state vision

The first step is to build a high-level view of the organization’s main processes, clarifying their scope, the areas involved, and their impact on key indicators. This view makes it possible to assess processes in an integrated way and select those that should be analyzed first.

Priority processes are analyzed end-to-end, combining detailed flow mapping with operational data and direct observation of the work. This approach makes it possible to objectively identify the main points of inefficiency, including waiting times, handoffs between areas, rework, non-value-added activities, and technological, organizational, or capacity constraints.

Based on this diagnosis, the organization can define a future-state vision for processes that are simpler, more agile, more reliable, and more customer-oriented. This vision should translate into a clear operating model, supported by quantified expected benefits and an implementation roadmap with priorities, owners, and deadlines.

This way, initially scattered opportunities are converted into a structured, achievable transformation plan that is directly linked to the intended strategic and operational results.

Implement improvements and sustain outcomes

Implementing the future-state vision should be carried out in close collaboration with the teams, through improvement workshops aimed at turning the opportunities identified into concrete solutions. With the participation of multidisciplinary teams, these sessions make it possible to detail the new process, test approaches, define standards, clarify responsibilities, and structure the implementation plan. The involvement of the people who know and execute the processes enhances the quality and applicability of the solutions, reduces resistance to change, and builds the necessary internal capabilities to ensure their continuity.

As improvements are implemented, performance indicators should be tracked regularly. Whenever deviations arise, they should trigger a structured analysis of the causes and the definition of the necessary countermeasures.

To sustain the results, new ways of working must be embedded in daily management. This means consolidating standards, clarifying decision-making and problem-escalation mechanisms, establishing follow-up routines, and empowering leaders to support their teams and promote continuous improvement in banking.

In this way, the transformation stops depending on a temporary project and becomes embedded in the organization’s management model, making it possible to sustain the gains achieved and continuously improve performance.

Sustainable efficiency as a competitive advantage

In banking, sustainable efficiency doesn’t come from one-off cuts or isolated automation initiatives. It is built through continuous process improvement, the intelligent use of technology, team development, and management focused on the customer and on results.

When this transformation is well-managed, the benefits go far beyond reducing the cost-to-income ratio. Processes become faster and more reliable, capacity is used more effectively, errors and rework decrease, and teams are able to devote more time to higher-value activities. At the same time, the customer experience improves, and the organization’s ability to respond to new regulatory, technological, and market demands increases.

Banks that integrate these dimensions develop operations that are more resilient, agile, and ready to grow. Efficiency therefore stops being just a cost-control measure and becomes a real competitive advantage, capable of sustaining banking profitability, strengthening customer trust, and supporting long-term value creation.

Reducing the cost-to-income ratio only becomes lasting once the operational gains become part of daily management. This is the work Kaizen Institute does with banks: transforming processes, developing teams, and embedding continuous improvement into the management model, through our consulting services for the financial sector.

Still have some questions about operational efficiency in banking?

How can a bank improve its operational efficiency in a sustainable way?

Sustainable improvement requires an integrated approach that combines process simplification, better use of resources, team development, and the careful application of technology. The goal should be to eliminate the structural causes of inefficiency, not just reduce costs in the short term.

How can the optimization of the branch network improve operational efficiency?

Optimization of the branch network is not limited to closing branches. It involves analyzing demand, location, customer profile, productivity, and the role of each branch, while adjusting formats, hours, capacity, and activities. The goal is to strengthen advisory services and the commercial relationship, reduce administrative tasks, and ensure more efficient use of resources.

What role does automation play in banking efficiency?

Robotic process automation in banking can reduce repetitive tasks, errors, and processing times. Intelligent automation in banking expands this potential by combining automation, artificial intelligence, and data analysis. However, these solutions should be implemented after processes have been simplified and redesigned.

How can the onboarding process and KYC automation be improved?

KYC, short for Know Your Customer, refers to the identification, verification, and customer-knowledge processes required to prevent fraud, money laundering, and other financial risks.

Improving customer onboarding in banking involves reducing duplicate information requests, integrating data and systems, automating validations, and managing exceptions in a structured way. KYC automation can speed up verifications, strengthen control consistency, and improve the customer experience without compromising compliance requirements.

Is the modernization of core banking essential for increasing efficiency?

Core banking refers to the set of core systems that support a bank’s main operations, such as account management, deposits, payments, loans, and customer data.

Its modernization can facilitate data integration, process automation, and the launch of new services, but it should not be seen as a stand-alone solution. Significant gains can be achieved through process improvement, branch network optimization, and the progressive integration of existing systems.
