BankUnited (BKU) Q2 2024: Non-Broker Deposit Growth Surges $1.3B, Reshaping Funding Mix
BankUnited’s transformation of its deposit base accelerated in Q2, as non-broker deposits climbed $1.3 billion and cost of deposits declined, further strengthening margin and funding stability. The bank’s multi-year investments in commercial, title, and HOA banking are now driving broad-based relationship growth, despite persistent office CRE risk and expense headwinds. Management signals continued focus on core DDA growth, but warns that seasonality and market conditions will moderate the pace in the back half of 2024.
Summary
- Deposit Mix Transformation: Non-broker DDA growth and lower funding costs drive margin expansion and balance sheet resilience.
- Commercial Lending Pivot: C&I and CRE growth offsetting legacy residential and leasing runoff, with targeted risk management in office exposure.
- Capital Deployment Watch: Management eyes organic growth but signals board-level capital return discussion for H2.
Business Overview
BankUnited (BKU) is a commercial bank focused on relationship-based lending and deposit gathering across Florida, New York, and select national verticals. The bank’s core business model combines commercial and industrial (C&I) lending, commercial real estate (CRE) financing, specialty deposit solutions (notably in title and HOA banking), and treasury management. Revenue is primarily generated from net interest income, supplemented by fee-based services such as commercial card, derivatives, and syndication. BKU’s strategic focus is on growing low-cost, non-interest-bearing demand deposits (DDA), optimizing asset mix, and managing credit risk, especially in office CRE.
Performance Analysis
Q2 marked a significant inflection in BankUnited’s funding profile, as non-broker deposits surged $1.3 billion, with $826 million in non-interest DDA—an 11% sequential increase—driving the cost of total deposits down for the first time in the rate cycle. This shift enabled a 15-basis-point net interest margin (NIM) expansion to 2.72%, fueled by both deposit mix improvement and the continued runoff of higher-cost wholesale funding. The bank’s asset mix also evolved, with $589 million of growth in core C&I and CRE loans offsetting a $212 million decline in residential mortgages and continued leasing runoff, reflecting a deliberate pivot toward higher-yielding, relationship-driven commercial lending.
Credit quality remained stable overall despite a $69 million increase in criticized and classified CRE assets, concentrated in office loans. Management proactively built reserves, with the office CRE reserve rising to 2.5% of balances, and emphasized that recent non-performing loan increases were fully anticipated and reserved. Non-interest income saw early benefits from recent investments in commercial card and capital markets, though lease income declined in line with the shrinking portfolio. Expenses were flat sequentially but are guided to rise mid-single digits year-over-year, partly due to planned railcar refurbishment costs.
- Deposit Cost Decline: Total deposit cost fell to 3.09%, reversing a multi-quarter uptrend and improving funding stability.
- Wholesale Funding Reduction: Brokered and FHLB funding dropped by $1.2 billion, returning to pre-rate cycle levels and lowering balance sheet risk.
- Commercial Lending Expansion: C&I and CRE loan growth was broad-based, with seven of the largest C&I segments and targeted CRE asset types (industrial, multifamily, grocery-anchored retail) all contributing.
While office CRE remains a watchpoint, the bank’s overall portfolio is characterized by strong sponsors and manageable exposure levels relative to peers. Management’s ability to grow DDA and commercial relationships at scale, while containing credit and funding risk, underpins the current margin and earnings trajectory.
Executive Commentary
"Deposit growth, which is the big story here, non-broker deposits grew by $1.3 billion this quarter, and off that $1.3 billion, $826 million was non-interest DDA, which is just a very, very solid number...That transformation...to the right side of the balance sheet is well underway."
Raj Singh, Chairman, President, and CEO
"We continue to expect the NIM to expand over the back half of 24, although I don't think we'll see 15 basis points per quarter...But still continue to expect NIM to end the year in the high twos."
Leslie Lunak, Chief Financial Officer
Strategic Positioning
1. Funding Mix Overhaul
BankUnited’s most decisive strategic lever this quarter was the acceleration of non-broker DDA growth, which enabled a reduction in costly wholesale funding and improved margin resilience. This shift is the result of multi-year product, technology, and relationship investments, not short-term rate chasing or producer hiring. The bank’s ability to drive DDA as a percentage of total deposits toward pre-pandemic highs (now 29%, up from 27% last quarter) is a key differentiator in the current rate environment.
2. Commercial Lending Focus
The bank is intentionally pivoting away from legacy residential and leasing exposures, redeploying capital into higher-yielding C&I and select CRE segments. Core commercial loan growth was broad-based, with targeted emphasis on industrial, multifamily, and grocery-anchored retail. Office CRE is being tightly managed, with new originations focused elsewhere and active monitoring of submarket risk.
3. Credit Risk Management
While office CRE risk remains elevated, management’s proactive reserving and asset-specific monitoring have limited portfolio deterioration. Office exposure is concentrated in Florida and New York, with strong sponsors and low loan-to-value (LTV) ratios (portfolio LTV 56%). The reserve build reflects anticipated lease-up and abatement challenges, but management signals that ultimate loss content is manageable and within modeled expectations.
4. Fee Income Diversification
Recent investments in commercial card, capital markets, and HOA banking are beginning to yield fee income growth, diversifying revenue streams and supporting relationship stickiness. While these contributions are still emerging, management expects a gradual increase in non-interest income, albeit with quarterly volatility.
5. Capital Deployment and Shareholder Returns
With capital levels building and organic growth opportunities robust, management is prioritizing loan and relationship growth over immediate capital returns. However, a board-level discussion on capital deployment (including potential buybacks) is planned for August, with the outcome dependent on sustained growth visibility and market conditions.
Key Considerations
This quarter’s results underscore BankUnited’s successful execution on funding, asset mix, and risk management, but the outlook is shaped by both internal discipline and external forces.
Key Considerations:
- Seasonality Impact on DDA: Management cautions that first-half DDA growth benefited from seasonality, with H2 expected to see slower or even negative seasonal effects.
- Office CRE Remains a Risk Hotspot: While reserves are robust and exposure is manageable, further migration in office loans is possible as lease abatements roll off and economic occupancy recovers.
- Expense Discipline vs. Investment Needs: Non-interest expense is guided to a mid-single-digit increase, with railcar refurbishment and compensation volatility as drivers; ongoing investment in technology and talent remains a strategic priority.
- Capital Allocation Flexibility: Any decision on share buybacks or capital returns will be balanced against growth opportunities and regulatory/rating agency considerations.
Risks
Key risks include further deterioration in office CRE markets, which could drive additional reserve needs or impairments, as well as margin compression if deposit growth slows or funding costs reaccelerate. Seasonality and macro uncertainty (especially around mortgage and title activity) may dampen DDA momentum in H2. Expense pressures, particularly from compensation and one-time costs, could outpace revenue growth if not carefully managed. Regulatory scrutiny on funding and capital deployment remains a background constraint.
Forward Outlook
For Q3 2024, BankUnited management guided to:
- Continued, but more modest, DDA growth as seasonality turns negative
- Ongoing margin expansion, with NIM expected to finish the year in the high 2% range
For full-year 2024, management maintained guidance:
- Mid-single-digit to low double-digit net interest income growth
- Mid-single-digit increase in non-interest expense (excluding FDIC assessments)
Management highlighted pipeline strength in commercial lending and deposit relationships, but reiterated that balance sheet growth will be flat for the year overall. Capital deployment decisions will be revisited at the August board meeting, with a bias toward organic growth if market conditions allow.
- H2 DDA growth expected to moderate due to seasonality
- Office CRE risk and reserve trajectory will remain a key watchpoint
Takeaways
BankUnited’s Q2 results reflect the payoff of long-term strategic investments in deposit gathering, commercial banking, and risk management, positioning the bank for continued margin resilience and funding stability.
- Funding Mix Shift: The acceleration of non-broker DDA growth and reduction in wholesale funding are reshaping the bank’s risk and earnings profile, with clear benefits to NIM and capital flexibility.
- Commercial Focus, Risk-Aware Growth: Asset mix is shifting toward higher-yielding, relationship-driven commercial loans, while office CRE risk is proactively managed with targeted reserving and asset-level monitoring.
- Watch H2 Seasonality and Capital Actions: Investors should monitor the pace of DDA growth as seasonality turns, as well as any board decisions on capital deployment or buybacks in the second half of the year.
Conclusion
BankUnited’s multi-year strategy to build a relationship-driven, low-cost funding base is now delivering tangible margin and earnings leverage, even as credit and expense risks persist. The bank’s disciplined approach to asset mix, funding, and capital deployment provides a solid foundation, but execution on commercial growth and risk management will remain critical as market conditions evolve in H2 2024.
Industry Read-Through
BKU’s experience this quarter provides a clear read-through for regional and commercial banks navigating the late-cycle environment: Relationship-driven DDA growth and funding mix optimization are key differentiators as wholesale funding costs plateau and deposit competition intensifies. The pivot away from residential and leasing toward C&I and select CRE is increasingly common, but requires disciplined risk management, especially in office exposures. Margin expansion is possible for banks that can grow core deposits and reprice assets, but expense discipline and capital flexibility are essential as credit normalization and regulatory scrutiny increase. For peers, BKU’s success with specialty deposit verticals (title, HOA, corporate banking) underscores the value of targeted investment and technology in driving sustainable relationship growth.
