How Banks Make Money: Culture. Not Kidding.

I recently spoke at a banking conference with a session titled: Profit Drill Down-How Banks Make Money. Below is a summary of my comments.

Core Thesis

Banks improve performance when executive-level KPIs are systematically translated (“waterfalled”) down to every level of the organization—so that individual roles, units, products, and customers all align to the same economic drivers. When done well, this creates a self-reinforcing culture—an “invisible hand” guiding behavior without constant top-down pressure.

1. The Problem: Strategy Doesn’t Reach the Front Line

• Banks typically track high-level KPIs (e.g., Net Interest Margin, ROE, efficiency ratio). 

• But these metrics often don’t translate meaningfully to frontline staff: 

Example: What does a 3.80% NIM target actually mean to a relationship manager?

Without translation, KPIs remain abstract, disconnected, and ineffective as drivers of behavior.

2. Culture as the Missing Link

• The presentation defined culture as: 

1. An“invisible operating system”
2. An alignment mechanism
3. A value creation engine 

Strong performance isn’t just about strategy—it’s about embedding that strategy into everyday decisions.

3. The Solution: KPI Waterfalling

The key idea is to decompose bank-level financial outcomes into actionable drivers at every level:

Example Cascades

• Net Interest Margin (NIM) → Branch KPIs (deposit mix, deposit spreads (%), deposit spread growth); Lender KPIs (loan spreads (%), loan spread growth) 

• Return on Equity (ROE) → Marketing KPIs (campaign ROEs); Lender KPIs (portfolio ROEs); Relationship KPIs (ROE hurdle rates) 

• Efficiency Ratio / Expense Control → Support function KPIs (opex/loans serviced), opex/deposits serviced)

Result: Each employee sees how their actions directly affect enterprise outcomes.

4. Extending to Products and Customers

• The framework emphasizes profitability at the product and customer level, not just the bank level by understanding: 

1. Which products generate the most risk-adjusted revenue
2. Which customers create or destroy value

Banks can allocate effort, pricing, and strategy more effectively.

5. Performance Insight: Variation Matters

• Benchmarking across banks shows wide dispersion between top- and bottom-quartile performers. Benchmarking within the bank can also be powerful, i.e. which Lender demonstrated the best improvement in loan spreads among our team of lenders?

• Trend compares apples-to-apples: how did the Market Street branch deposit spread improve over time? 

This highlights: 

o Execution—not just strategy—is what differentiates performance

o Proper alignment and accountability can close that gap

6. Cultural Impact: Turning KPIs into Behavior

When KPI waterfalling is done correctly:

• Everyone shares the same goals, not just executives

• Employees feel: 

1. Connected to the strategy
2. Supported rather than policed 

• Decision-making becomes: 

1. Faster. There is greater empowerment, less policing
2. More consistent
3. Economically aligned

7. Key Takeaways

• Tie strategy → KPIs → compensation → daily activities across all levels

• Make KPIs relevant and actionable for each role

• Use alignment to create a performance-driven culture without constant oversight

• Culture becomes the“invisible hand” that drives sustained improvement 

Bottom Line

The presentation argued that financial performance is not just a function of strategy—it’s a function of alignment.

When banks successfully cascade KPIs from the boardroom to the frontline and down to individual customer decisions, those KPIs stop being metrics and instead become shared goals that shape behavior, ultimately driving superior, consistent performance.
