Every bank has a deposit ecosystem. Every individual branch has one as well. It is already there, already functioning, already influencing every number on every report. Most bankers don’t see it because it has always been in motion, it acts like a tide that rises and falls with market conditions. It’s shaped by customer habits, relationship history, daily flows, internal culture, pricing decisions, and even the personalities of the people inside the branch.
For example, a dollar could enter the system, say, by a business client making a sale. Once that dollar is in the bank, a strong deposit ecosystem moves it through its natural course of life in your system. So, the dollar would go into business checking, then to business payroll, then to the employee on pay day.
But that is where most banks lose the deposits. A characteristic of a strong ecosystem would be that the employees bank with you too, as does the hardware store down the street, the roofer, the painter, the accountant, and even the employees’ babysitter.
The name of the game becomes “how long can you hold the money in your ecosystem?”
This is a very powerful concept.
I have learned that when a bank wants to grow low-cost and core deposits, and stabilize or lower its cost of funds, the starting point for many might be a new product or a promotion. But the secret is that the starting point is understanding what is already happening in the system and then pulling the right levers.
Early in my career, I thought deposit growth came from the same places most bankers assume. Rates. Promotions. Marketing campaigns. All of those are important levers. Over time, working inside and around dozens of institutions, speaking with countless bank and credit union CEO’s and Retail Deposit experts, I realized the best growth actually comes from how well a bank understands the quiet movements of money already within its walls.
How the money comes in, what it does while it’s here, and most importantly, where does it go when it leaves?
When a bank sees the ecosystem clearly, it understands which customer groups are stable, which are price-sensitive, which products hold balances longest, and where deposits tend to evaporate without warning. Until you see that picture, every strategy is a guess.
I have also found that once a bank understands its ecosystem, it becomes easier to spot the simplest, lowest-cost opportunities. Often the most impactful changes are not expensive. They are behavioral and emotional. They are powered by employees who know what to pay attention to, when to listen, when to talk. They know what to say & how to say it. Without this understanding, many banks end up chasing external trends that never stick, or are investing in expensive efforts that simply do not align with their true deposit base.
When banks take the time to understand their deposit ecosystem, something powerful happens. Decisions become clearer. Priorities sharpen. Strategies become more rooted in reality than in wishful thinking. And rather than constantly reacting to market waves, banks can begin shaping the current inside their own four walls.
Below are some of the best lessons, and most powerful secrets I’ve collected over the years that help community banks and credit unions build profitable deposit relationships and strategies.
1. Align Banking Employee Incentive Plans With the Right Products and Behaviors
Over the years, I have seen tons of incentive plans. They are always well-intentioned yet unintentionally rewarded the wrong behaviors. Some even created ways for employees to skirt the system. Many were presented by executives in a way that was too confusing for the team, and hard for an employee to calculate how to reach their personal goals via the plan. A plan may look logical on a spreadsheet, but it ended up producing short-term bursts instead of long-term results. In most, employees were rewarded for volume instead of value, or for product pushes. This disconnect quietly shapes the culture more than leadership realizes.
The most effective incentive plans that I have seen rewarded behaviors that genuinely create long-term value. Those behaviors tend to involve relationship development, customer retention, deepening accounts, and identifying opportunities that fit the bank’s strategic goals. When incentives acknowledge thoughtful, customer-centered behavior, employees stop chasing the wrong carrots and begin acting in ways that strengthen the entire ecosystem. If you want to lower your cost of funds, why incentivize growing high-rate CD promotions?
One of the biggest secrets that I learned is that incentives do not always need to be financial. Employees often appreciate time more than money. If a bank offered extra PTO days as rewards, the motivation that generates is remarkable. One more day with family, one more long weekend, one more day to breathe—these things create enthusiasm and commitment in ways a small cash bonus never will. Those rewards also cost the bank far less than a recurring monetary bonus structure.
I have also seen how incentive plans influence collaboration. When rewards are structured in a way that encourages teamwork instead of individual wins, employees begin sharing information, supporting each other, and identifying opportunities across the organization.
A team meeting where each person shares their vision and goal of what they want to achieve can be tremendously motivational. The bank benefits from a unified approach rather than internal competition. A well-designed incentive plan doesn’t just influence performance, it shapes culture. And culture, more than anything else, determines how money and people flow in and out of a bank.
2. Rate Repricing with Honesty and Respect
Repricing is one of the most sensitive strategies in banking, yet it is often handled in the most impersonal way possible. I spent years watching institutions quietly lower rates and hope customers wouldn’t notice. What a missed opportunity. That approach almost always backfires. Customers eventually notice, and when they do, the trust has already been damaged. What I’ve learned, is that honesty and proactive communication create the opposite effect.
This may shock you, and you may roll your eyes, but personally calling individual customers when rates needed to be lowered is one of the most powerful activities a bank can do. It sounds daunting at first, it was one of the most impactful cultural shifts I was ever part of. During these calls, we explained what was happening in the rate environment and why their account was being adjusted. We walked them through the math. We treated them with respect. Not just their money- them. What surprised me was how willing customers were to have that conversation. Most appreciated the transparency because very few institutions take the time to show that level of regard and genuine concern.
Over time, I learned another valuable lesson: those honest conversations often led to more deposits, not fewer. After explaining the change, we would ask whether they had other accounts elsewhere that were underperforming or being neglected. I was amazed at how frequently customers responded by moving over additional money. Some said they were rewarding honesty. Others said they trusted us more because we were willing to make the uncomfortable phone call instead of hiding.
These experiences taught me that repricing is not simply a transactional change. It is a relationship building opportunity. Customers do not leave because a rate was adjusted. They leave because they were placed in the dark about their own money. When repricing is handled with respect, clarity, and transparency, it can become a loyalty-building event instead of a withdrawal trigger.
3. Growing Core Deposits Through Unexpected Value
I have watched many banks chase rates, or fee-sensitive customers because of urgent loan funding needs, instead of keeping their eye on this prize. The banks that consistently build strong deposit bases do something different. They create value far beyond rate.
I have seen branches become true community hubs. Not because they held events, but because they provided meaningful access and support to local businesses and residents. Some offered their conference rooms for business owners who had nowhere else to meet. Others provided technology for customers who needed help with presentations, interviews, or virtual meetings. These actions cost almost nothing and yet, created an emotional connection that no competitor could easily replicate.
The branches that embraced this approach discovered that customers kept significantly more deposits with that bank and gave them the first crack at their loan opportunities.
When a business owner sees the bank as a partner rather than a vendor, deposits stick. When a family sees the branch as a friendly place where real people help them solve real problems, balances grow. I have seen this happen repeatedly, in both small towns and large suburban communities.
I have also learned that providing a great idea is one of the most valuable gifts a banker can offer. When bankers share insights about cash flow, seasonal trends, fraud prevention, payroll timing, or operational efficiencies, customers begin seeing the bank as a source of guidance. When that happens, they no longer compare institutions purely on rate. Their relationship with the bank becomes deeper, more personal, and far more stable.
Ultimately, the banks that understand the idea of becoming the most trusted and valuable entity that clients have in their lives, then massive growth in low-cost deposits usually follows. That value becomes the anchor that keeps the ecosystem stable.
4. New Client Bonus Promotions vs. Loyalty Programs
New client cash bonuses have become increasingly common in banking. Over time, I have come to believe they do more reputational harm than good. One lesson stands out above the rest: whatever brings a customer in the door, if left unchecked, is usually the same thing that eventually sends them out. When customers join for rate, they will leave for a better rate. When they join for a $300 bonus, they leave for a $400 bonus. Many even track these promotions like a side business.
I have watched banks pour enormous budgets into these promotions, only to see deposits disappear the moment the required minimum period ends. Now I know there are studies out there that show pure profitability, and many times, the net result is a positive one on the balance sheet. Yet, these promotions create the reputation and the brand of a community bank. Not only does this create volatile and hollow relationships, it anchors the bank’s reputation to the idea that it needs to pay people to join them. That is not the message an institution wants to project in a competitive market.
The banks that avoid this trap invest their dollars into loyalty-building programs instead. They create experiences that rate-sensitive banks cannot match. They strengthen the emotional ties that customers feel toward the institution. These efforts stabilize balances and create deeper long-term value. Customers who join for the right reasons stay for the right reasons.
I have also learned that when a bank stops chasing promotions, its internal data becomes more accurate. Average balances stabilize. Forecasting becomes easier. The roller-coaster effect disappears. Everything becomes more predictable. Stability, as I’ve seen it, is one of the most underrated competitive advantages in banking.
5. The Stabilizing Power of “Bank at Work”
Of all the tools available to community banks, “Bank at Work” may be the most underestimated and underutilized. Payroll is a company’s largest expense, and every payday, a wave of low-cost deposits leaves the bank. When a bank builds strong “Bank at Work” relationships, that wave of deposits out, slows for long periods of time.
I have conducted “Bank at Work” sessions in offices, warehouses, break rooms, parking lots, and everywhere in between. I learned that employees appreciate individualized attention far more than promotions or new customer bonuses. Most do not need cash incentives to move their accounts. They need to understand exactly how little time and effort it will take on their part to switch. And they need to know that someone from the bank will take the time to understand their financial situation and offer practical guidance, in many cases, direct them and hold their hand during the switch.
During these sessions, we would sit together, one-on-one, and review the employee’s financial picture. Many were not looking for a rate. They were looking for clarity and strategy. Advice. Confidence. Reassurance. Those conversations turned into trust, which turned into relationships, which turned into long-term clients. And those employees told their families, which brought in more households.
Over time, I began seeing “Bank at Work” not as a product, but as a relationship engine. It builds stories that customers carry with them. Stories they share with people who need a new bank. These stories become the quiet, organic growth that no marketing budget can ever purchase.
The institutions that reinvest in “Bank at Work” often discover that it becomes one of the most reliable sources of stable, low-cost deposits in their entire ecosystem.
Bringing All Five Levers Together
When these levers operate together, I have seen deposit ecosystems transform. Balances rise. Loyalty strengthened. Your cost-of-funds decreases steadily. The bank becomes far less dependent on unpredictable external tides. Instead of reacting to market waves, it begins shaping its own internal current.
After nearly three decades in this work, I’ve seen community banking reaches its highest potential when people (clients and employees alike) feel connected to something meaningful. When a bank understands its ecosystem, respects its customers, supports its employees, and fosters real relationships, it creates long-term profitability that cannot be outbid, undercut, or out promoted.
In the end, a well understood and healthy deposit ecosystem is the most powerful engine of growth a community institution will ever have. I hope these tips, tricks and concepts provide a small blueprint for quality deposit growth.
