How Credit Unions Can Grow in 5 Different Interest Rate Environments

Written by Preston Packer | Jan 23, 2025

Economic conditions are constantly changing. Interest rates rise and fall, often unpredictably, and each shift can feel like navigating uncharted waters.

What worked last year—or even last quarter—might not be the best approach today.

So, how can credit unions thrive in such unpredictable conditions? By aligning strategies to the economic climate, it’s possible to turn rate fluctuations into opportunities for sustainable growth.

This blog explores actionable ways to attract members, grow deposits, and maintain loan performance—no matter where interest rates are headed. Let’s dive in.

Key Takeaways

  • Adapt to Interest Rate Changes: Tailor strategies for rising, falling, or stable rates to ensure sustainable growth and profitability.
  • Focus on Member Engagement: Whether rates are high or low, strengthening relationships and offering valuable services is essential for retention.
  • Optimize Operations: Streamline processes and manage costs to stay efficient, regardless of economic conditions.

 

What is the Relationship Between Credit Union Growth and Interest Rates?

Interest rates play a pivotal role in the growth and sustainability of your credit unions.

They impact nearly every facet of operations, from member borrowing behavior to the ability to maintain competitive savings products.

To truly understand this relationship, let’s break it down into three critical components: net interest margin, asset and liability mismatch, and liquidity management.

Net Interest Margin

The net interest margin (NIM) is the difference between the income a credit union earns on loans and the interest it pays on deposits.

This metric directly correlates with interest rates:

  • In rising interest rate environments, credit unions may experience a widening NIM as loans reprice at higher rates faster than deposits.
  • In falling rate environments, the reverse is true, with NIM compressing as deposit rates lag loan repricing.

Managing NIM is essential to maintaining profitability and reinvesting in member services. 

Asset and Liability Mismatch

One of the biggest challenges for credit unions is the mismatch between the maturity of assets (e.g., loans) and liabilities (e.g., deposits). This mismatch becomes especially pronounced when interest rates change quickly.

For example:

  • Fixed-rate mortgages held during a period of rising interest rates lose value because they yield less compared to new loans issued at higher rates.
  • On the flip side, variable-rate loans adjust more quickly, allowing credit unions to adapt to rate changes more effectively.

Balancing short- and long-term assets with corresponding liabilities is crucial to mitigating this risk and ensuring long-term stability.

Liquidity Management

Liquidity—the availability of funds to meet member demands—is another area influenced by interest rates. High or rapidly changing rates can cause:

  • Decreased deposit inflows: Members may move funds to accounts offering better returns or alternative investments.
  • Higher costs of funding: Credit unions may need to offer more competitive deposit rates to retain members, tightening margins further.

Effective liquidity management ensures that a credit union can navigate periods of market uncertainty without sacrificing service quality. 

 

How to Grow in Each Different Interest Rate Environment

Your credit union must adopt tailored strategies to thrive in varying interest rate environments. Whether rates are climbing, falling, or holding steady, the ability to adapt is key to sustaining growth and delivering value to members.

 

Rising Interest Rates

In a rising interest rate environment, your credit union faces the dual challenge of increased borrowing costs and heightened competition for deposits.

However, this environment also offers opportunities for growth through strategic lending, member-focused deposit strategies, and operational efficiency.

1. Attract and Retain Deposits

Rising rates create competition among financial institutions for deposits as members seek higher returns. To stay competitive:

  • Offer attractive rates on high-yield savings accounts or share certificates (CDs) to draw in deposits.
  • Consider creating tiered deposit products that reward members for higher balances or longer terms.
  • Leverage member education to highlight the safety and reliability of credit union deposit accounts compared to riskier investments.

2. Streamline Operations

Operational efficiency is critical in a rising rate environment to offset increased borrowing costs and competitive deposit rates. To improve margins:

  • Invest in technology to automate back-office tasks and improve service delivery.
  • Regularly review operational expenses to identify cost-saving opportunities without sacrificing member experience.

3. Promote Loyalty through Rewards Programs

Members are more likely to remain loyal to institutions that demonstrate value beyond rates.

Consider implementing or enhancing rewards programs for loans, credit cards, or member referrals to encourage continued engagement with your credit union.

By focusing on these strategies, your credit union can grow even as interest rates rise, ensuring continued financial strength and member satisfaction.

 

Falling Interest Rates

In a falling interest rate environment, credit unions face reduced loan yields but can also benefit from increased loan demand and opportunities to attract new members.

Strategic planning and member-focused solutions can help offset the challenges and leverage the opportunities presented by lower rates.

1. Expand Loan Portfolios with Targeted Offers

Lower interest rates tend to drive borrowing activity. This is the time to promote high-demand products like mortgages, auto loans, and refinancing options.

For example, launching limited-time offers on personal loans or home equity lines of credit (HELOCs) can help your credit union capture this momentum.

Case in point: A well-timed mortgage refinancing campaign, paired with streamlined application processes, can attract both existing and potential members eager to lock in lower rates.

2. Invest in the Member Experience

Falling rates provide an opportunity to shift focus toward enhancing the member experience. Now’s the time to upgrade your digital offerings or improve operational efficiency.

For example, enhancing mobile banking features or incorporating AI-driven personalization tools can elevate your credit union above competitors.

Additionally, streamlined automation can reduce costs while improving service quality.

3. Differentiate Your Credit Union’s Value

As borrowing costs decline across the board, it’s critical to stand out in a crowded financial landscape. Position your credit union as a partner in your members’ financial journeys by emphasizing your unique strengths:

  • Showcase your commitment to the community through partnerships and volunteer efforts.
  • Appeal to younger members with campaigns that focus on first-time home or car buyers.

4. Diversify Revenue Streams for Long-Term Stability

With compressed margins, diversification is key. Explore alternate revenue sources such as fee-based services like financial planning or investment advice. Collaborations with fintech partners can also expand your offerings, such as digital budgeting tools or insurance products.

 

Stable Interest Rates

When interest rates are stable, credit unions can use the predictability of the market to focus on long-term strategies that build a strong foundation for sustainable growth. Here are key approaches to consider:

1. Strengthen Member Relationships

A stable rate environment is the perfect time to deepen member engagement. With fewer dramatic shifts in lending or deposit costs, credit unions can focus on nurturing trust and loyalty.

  • Conduct financial wellness check-ins: Use this period to proactively engage members with personalized advice. For instance, recommend savings products or debt repayment strategies tailored to their unique needs.
  • Develop loyalty programs: Offer incentives for members who use multiple services, such as linking savings accounts, credit cards, and loans into a bundled rewards program.

2. Optimize Operational Efficiency

With reduced urgency to adapt to shifting rates, your credit union can focus on improving internal processes. This could involve:

  • Streamlining workflows to reduce overhead costs.
  • Upgrading digital platforms to create smoother, more seamless member experiences.
  • Investing in staff training to enhance service quality and boost productivity.

By cutting costs while enhancing service, your credit union can improve margins and retain satisfied members.

3. Plan for Future Market Shifts

Stability provides a unique opportunity to prepare for future rate changes. By building reserves, assessing risk exposure, and optimizing asset-liability management strategies, your credit union can be better positioned for an eventual rise or fall in rates.

 

Low Interest Rate Environment

A low interest rate environment presents both opportunities and challenges for credit unions. While reduced borrowing costs can boost loan demand, declining margins may pressure profitability. Here’s how credit unions can navigate these dynamics to achieve growth:

1. Promote Loan Products Aggressively

Low rates are attractive to borrowers, making this the ideal time to boost loan volumes.

  • Mortgage and Auto Loans: Highlight competitive fixed and variable-rate options to encourage members to refinance or purchase new homes and vehicles.
  • Personal Loans: Promote affordable personal loans for debt consolidation, home improvements, or other needs, providing members with a cost-effective solution.

Example: Offer limited-time promotions like no origination fees or discounted rates for members who meet specific criteria, such as automatic payments.

2. Expand Lending to New Segments

Use low rates to attract members who might not have borrowed in a higher-rate environment.

  • Younger Members: Tailor loan products to first-time homebuyers or students seeking affordable borrowing options.
  • Small Businesses: Offer competitive business loans to support growth initiatives in your local community.

3. Control Operational Costs

Slimmer margins mean credit unions must optimize efficiency without sacrificing service quality.

  • Technology Investments: Automate high-volume tasks like loan processing, member account updates, or fraud detection. This reduces staff workload while improving turnaround times.
  • Optimize Branch Operations: Shift to a digital-first model, reducing reliance on physical branches. Offer virtual consultations and prioritize digital onboarding for members who prefer online interactions.
  • Data-Driven Decision Making: Use analytics to pinpoint inefficiencies and target cost-saving measures effectively.

In a low interest rate environment, managing operational costs is crucial for maintaining financial stability and growth.

These strategies not only protect margins but also position your credit union for long-term success in an ever-changing economic landscape.

 

High Interest Rates

Periods of high interest rates can present unique challenges, including reduced borrowing demand and increased member caution. 

However, these times also provide opportunities to strengthen relationships with members and enhance long-term financial stability.

Here's how your credit union can thrive in a high-interest-rate environment:

Emphasize Deposit Products with Competitive Rates

High interest rates create an opportunity to attract deposits by offering competitive returns. Members looking for safe, high-yield savings options will turn to accounts like:

  • Certificates of Deposit (CDs): Highlight longer-term CDs with attractive rates, emphasizing security and guaranteed returns.
  • Money Market Accounts: Offer flexible options with higher yields for members who want both returns and liquidity.

Position these products as valuable tools for members to grow their savings and safeguard against inflation.

Prioritize Risk Management

High interest rates can increase exposure to credit risk. Proactively managing risk ensures your credit union remains resilient:

  • Monitor loan portfolios closely for signs of stress, particularly among borrowers with variable-rate loans.
  • Tighten underwriting standards while maintaining accessibility for members with strong financial profiles.

Building robust risk management systems will protect the credit union’s financial health during volatile periods.

Enhance Member Retention Efforts

In challenging economic conditions, maintaining strong relationships with members is essential. Focus on enhancing retention through:

  • Exceptional Service: Train staff to proactively address member concerns and offer personalized financial solutions.
  • Member Benefits: Strengthen loyalty programs, offering rewards for deposit growth or long-term membership.

Keeping your members engaged and supported will help your credit union navigate high-rate periods successfully.

By implementing these strategies, your credit union can capitalize on the opportunities presented by high interest rates while mitigating potential risks.
