A Playbook for Defending Your Deposits

Deposit growth remains a priority for the vast majority of banks in 2026. However, in the current rate environment, deposit competition has intensified, forcing banks to look beyond rates to differentiate their deposit offerings.

Banks and fintechs are using a range of tactics to attract new customers, including cash incentives to persuade depositors to move their primary relationships. These offers can be a powerful driver of switching, but they also add to the cost of acquiring new customers.

For community banks, this makes retaining existing relationships increasingly important — and potentially more cost-effective than replacing deposits once they leave. Here are five strategies to help defend your deposit base.

1. Identify at-risk deposits.
The first step is understanding which customers and balances are most vulnerable to competitor offers. Community banks can do this by segmenting deposits by customer type, account type, balance, tenure and rate sensitivity. Segmentation can help identify patterns that indicate which customers and deposits are most likely to leave — like those with large, rate-sensitive balances or newer relationships with limited activity — allowing institutions to focus retention efforts where they are most needed.

Institutions should also look at declining volume or value in account activity to identify the risk of ‘soft switching.’ Customers do not always close an account when they move their primary relationship, so a gradual reduction in activity can be an early warning sign that the account is becoming secondary.

2. Assess deposit stickiness.
Not all at-risk deposits are equally valuable. Community banks should distinguish genuine relationship-based balances from deposits primarily attracted by rates, promotional offers or other incentives, while considering the broader profitability of each customer relationship. Reviewing transaction behavior ­— such as using the account for payroll, bill payments, debit-card purchases and recurring transfers — is a useful way to assess stickiness.

A deposit may carry significant value when it contributes to a profitable, multi-product relationship, while a rate-sensitive balance may offer less value once the cost of retaining it rises. This distinction can help community banks decide where to focus their retention efforts, rather than simply matching a competitor’s rate.

3. Reward primary account behavior.
Once community banks have assessed deposit stickiness, they can reinforce it to increase retention. Accounts exhibiting the transaction patterns described above are typically functioning as a customer’s primary financial relationship, and therefore harder to disrupt.

Institutions should structure retention offers that reward and reinforce these behaviors rather than simply offering a flat rate bump. A pricing concession tied to direct deposit enrollment, for example, can both retain the balance and deepen the relationship, making the customer less likely to move, and more costly to poach.

4. Empower frontline teams.
Retention decisions are often made in real time, when a customer signals that they are considering moving their relationship.

Frontline teams therefore need timely visibility into which customers may be at risk, along with clear parameters for when and how to intervene. This could include access to pre-approved retention offers or some discretion to tailor an offer to the value of the relationship. Lengthy escalation processes can mean the opportunity to retain the customer has already passed by the time approval is secured.

Giving frontline teams the right information and appropriate authority will enable community banks to respond quickly, while keeping retention decisions within defined parameters.

5. Plan for likely deposit runoff.
Finally, retention strategy needs to connect to balance sheet management. Deposit outflows can force community banks to replace lower-cost funding with more expensive sources, affecting both liquidity and profitability.

Institutions should therefore factor expected attrition into deposit forecasts, liquidity stress testing and asset-liability committee (ALCO) reporting, particularly for balances showing signs of rate or promotional sensitivity.

By segmenting deposits according to their likelihood of leaving and modeling the timing and cost of potential outflows, ALCO can assess how much funding could leave, how quickly the community bank would need to replace it and what that replacement might cost.

Parting Advice
Together, these strategies can turn deposit retention from a reactive, rate-driven scramble into a disciplined strategy. The goal is not to retain every deposit at any cost, but to protect the relationships worth keeping while preparing the balance sheet for those that may leave. Bringing retention into strategic and balance-sheet decision-making helps community banks respond more effectively to competitive pressure and build greater funding resilience.
