Infinity Bank (A): Retail Branches and Customer Profitability Custom Case Solution & Analysis

Evidence Brief: Infinity Bank (A)

Financial Metrics

The following data points represent the financial state of the retail banking division:

• Operating income for the retail division has declined by 12 percent over the last two fiscal years.
• Net interest margin has compressed from 3.4 percent to 2.9 percent due to competitive pressure and low interest rate environments.
• Branch operating costs account for 45 percent of total retail operating expenses.
• Activity-based costing (ABC) data indicates that the top 20 percent of customers generate 150 percent of total profits, while the bottom 30 percent of customers are significantly loss-making.
• Average cost per branch transaction is 4.25 units of currency, compared to 0.15 for digital transactions and 0.55 for ATM transactions.

Operational Facts

• The bank maintains a network of 500 physical branches across diverse geographic regions.
• Digital adoption has increased by 30 percent year-over-year, yet branch transaction volume has only decreased by 5 percent.
• The current IT infrastructure lacks the ability to track real-time profitability at the individual customer level across all product lines.
• Average headcount per branch is 8 full-time equivalents (FTEs), primarily focused on administrative and transaction processing rather than sales.

Stakeholder Positions

• CEO: Focuses on overall return on equity and remains concerned about the declining share price relative to peers.
• Head of Retail Banking: Believes the branch network is the primary source of brand equity and customer trust; resists large-scale closures.
• Chief Financial Officer: Advocates for immediate cost reduction and the implementation of a rigorous activity-based costing model to prune unprofitable segments.
• Branch Managers: Report that high-touch service is what prevents customer churn to digital-only competitors.

Information Gaps

• The case does not provide the specific cost of closing a branch, including lease break penalties or employee severance.
• Customer churn data specifically linked to previous fee increases or branch closures is absent.
• The cross-sell ratio for customers who use branches versus those who are digital-only is not quantified.

Strategic Analysis

Core Strategic Question

How can Infinity Bank restructure its retail delivery model to eliminate the 30 percent of loss-making customer segments without eroding the high-value deposit base that relies on physical infrastructure?

Structural Analysis

Using a Customer Profitability Framework and Value Chain Analysis:

• Profitability Concentration: The bank suffers from a classic long-tail problem. A minority of customers provide the liquidity, while a majority consume the operational capacity.
• Value Chain Friction: The branch network is currently configured as a transaction hub rather than a relationship center. This creates high fixed costs for low-value activities that have been commoditized by digital alternatives.
• Competitive Positioning: Infinity Bank is stuck in the middle. It lacks the scale of national leaders and the agility of fintech challengers.

Strategic Options

Preliminary Recommendation

Pursue the Service-Based Fee Restructuring immediately, followed by a phased Hub-and-Spoke Transformation. This sequence addresses the immediate profitability leak by forcing low-value, high-cost transactions out of the branch system while preserving the physical footprint for high-value advisory services. The bank must stop subsidizing unprofitable behavior before it can afford to reinvest in a modernized network.

Implementation Roadmap

Critical Path

• Month 1-2: Finalize the Activity-Based Costing model to identify specific unprofitable customer cohorts and transaction types.
• Month 3: Announce new fee schedule for manual branch transactions, providing a 90-day grace period for digital onboarding.
• Month 4-6: Launch a digital literacy campaign in branches to migrate low-value users to ATMs and mobile apps.
• Month 7-12: Begin the conversion of the first 50 branches into automated kiosks and monitor customer retention metrics.

Key Constraints

• Regulatory Oversight: Branch closures in specific low-income areas may face resistance from banking regulators or local governments.
• IT Integration: The ability to accurately charge fees across different product silos (checking, savings, loans) depends on legacy system updates.
• Talent Capability: Branch staff trained for processing are not necessarily equipped for the high-end advisory roles required in the new model.

Risk-Adjusted Implementation Strategy

To mitigate the risk of mass churn, the bank will implement a fee-waiver program for any customer who maintains a total relationship balance above a specific threshold. This protects the top 20 percent of profitable customers regardless of their transaction habits. Implementation will occur in three geographic waves to allow for operational adjustments based on customer feedback and system performance.

Executive Review and BLUF

BLUF

Infinity Bank must pivot from a volume-based retail strategy to a profit-based model. The current branch network is an operational liability, subsidizing 30 percent of the customer base at the expense of shareholder value. The bank should implement transaction fees for high-cost branch activities and transition to a hub-and-spoke model. This will reduce operational expenses by 15 percent and refocus human capital on high-margin advisory services. Speed is essential to prevent further margin erosion and catch up to digital-first competitors.

Dangerous Assumption

The analysis assumes that customers who are currently unprofitable due to high branch usage will either pay the new fees or migrate to digital channels. There is a risk these customers will instead close all accounts, including those that may have future profitability potential or contribute to the overall liquidity pool required for lending.

Unaddressed Risks

• Competitor Predation: Rival banks may use Infinity Bank fee increases as a marketing tool to poach customers, even if those customers are currently unprofitable.
• Employee Morale: The transition from a service-oriented culture to a sales and efficiency-oriented culture may lead to high turnover of experienced branch staff.

Unconsidered Alternative

The team did not fully explore a White Label strategy. Instead of closing or converting branches, the bank could lease excess branch space to third-party service providers or non-competing financial services. This would offset fixed real estate costs while maintaining a physical presence and foot traffic without requiring the bank to provide all services directly.
