BKU Q1 2023: $1.8B Deposit Outflow Triggers Strategic Shift Toward Core, Relationship Deposits
BKU faced a sudden $1.8B deposit outflow, catalyzing a pivot away from price-sensitive, non-strategic funds in favor of granular, relationship-driven core deposits. Management’s focus is now on deposit quality, funding mix, and margin stabilization, while capital remains robust and loan growth is recalibrated for risk and return. Investors should watch for execution on deposit pipeline conversion and the pace of balance sheet remixing as key levers for future profitability.
Summary
- Deposit Quality Pivot: BKU is actively shifting away from lumpy, price-sensitive deposits to build a granular, core-funded franchise.
- Margin Compression Persists: Funding mix pressure and wholesale reliance continue to weigh on net interest margin.
- Relationship Banking Emphasized: Strategic focus turns to full-service, operating account clients over transactional lending or CRE expansion.
Business Overview
BankUnited (BKU) is a regional commercial bank operating primarily in Florida and select growth markets such as New York, Atlanta, and Dallas. BKU generates revenue through traditional banking activities—primarily lending (commercial & industrial (C&I), commercial real estate (CRE), residential mortgage, and specialty finance) and deposit gathering, with a business model increasingly centered on relationship-based, operating accounts. Major segments include C&I, CRE, residential mortgage (Resi), and specialized verticals like title services.
Performance Analysis
BKU’s first quarter was defined by acute deposit volatility, with $1.8 billion in outflows concentrated among 10 institutional clients during the March banking turmoil. While deposit flows normalized quickly, the event exposed the fragility of large, price-sensitive balances, prompting management to deprioritize efforts to reclaim these funds. Loan growth was effectively flat, in line with seasonal patterns, with C&I balances up and residential mortgage shrinking, reflecting a strategic remix toward higher-return lending.
Net interest margin (NIM) came under renewed pressure, driven by a mix shift away from non-interest-bearing deposits and increased reliance on high-cost wholesale funding. Management estimates this mix shift compressed NIM by 14 basis points sequentially. Operationally, the bank absorbed $4.2 million in unusual losses tied to fraud and check-kiting, and non-interest income was hit by losses on preferred equity investments. Expense discipline is in focus, but investment in producer talent and growth markets remains a priority.
- Deposit Outflow Concentration: The $1.8B outflow was isolated to 10 clients, mostly fiduciary-driven institutional accounts, with little impact on the broader customer base.
- Funding Mix Headwind: Increased use of wholesale and reciprocal funding raised deposit costs and diluted margin, with average deposit cost jumping from 1.42% to 2.05%.
- Balance Sheet Remix: Ongoing reduction in residential and securities portfolios, with C&I targeted for growth and CRE kept flat, signals a pivot to relationship-driven lending.
BKU’s capital ratios remain robust, even under adverse mark-to-market scenarios, and liquidity coverage of uninsured deposits is strong at 128%. However, the earnings trajectory is closely tied to the pace of deposit pipeline conversion and the effectiveness of remixing the asset base.
Executive Commentary
"Our business is stable and growing. Our liquidity position is strong and our capital base is robust. March 13th was certainly disruptive. It cost us about a billion eight in deposit balances, but deposit flows basically the week after that returned to normal."
Raj Singh, Chairman, President and CEO
"Given the starting point and the fact that we're still holding a higher than normal level of cash on the balance sheet, the NIM will be under pressure again next quarter... If we keep deposits and the funding mix flat over the remainder of the year, see the strategic shift in loans that Raj described, I'd expect an NIM for the year in the 250s. We think we can do better than that."

Strategic Positioning
1. Core Deposit Growth as Top Priority
Deposit pipeline health is now the primary strategic lever. Management is focused on granular, operating account relationships—especially middle market and small business—rather than large, price-sensitive institutional funds. The current pipeline is $1.5–2 billion, with conversion expected over several quarters. The bank is investing in digital capabilities, onboarding new teams (notably from HSBC and in Dallas), and launching new consumer checking products to support core deposit growth.
2. Relationship-Driven Lending and Asset Remix
BKU is shifting away from transactional, credit-only lending, particularly in CRE, and emphasizing full relationship banking (including treasury and deposit services). The residential mortgage portfolio, built up during the pandemic, is being allowed to run off, with C&I as the designated growth area. CRE exposure is being tightly managed, especially in New York, with office and rent-regulated multifamily held flat or reduced.
3. Margin and Funding Mix Management
Margin recovery will hinge on improving the funding mix, reducing reliance on wholesale borrowings, and remixing deposits toward lower-cost, core sources. Management is working to optimize the FHLB advance portfolio and expects to lower its cost structure over time. Non-interest-bearing deposit balances are likely to remain under pressure, but a return to pre-pandemic lows is not anticipated.
4. Capital and Liquidity Strength
Capital ratios remain well above regulatory minimums, even if unrealized losses are included. Liquidity coverage is strong, and the bank has ample capacity to add brokered deposits if needed, though management prefers organic growth. The buyback remains suspended, with capital expected to accrete until visibility improves.
5. Disciplined Expense Management with Selective Growth Investment
While expense control is being tightened, investment in revenue-producing talent and new market expansion continues. Management is clear that long-term profitability will be driven by revenue and asset mix, not cost cuts alone.
Key Considerations
This quarter marks a strategic inflection point for BKU, with management openly pivoting toward sustainable, relationship-based funding and away from opportunistic, volatile deposits. The ability to execute on this strategy will determine the pace of margin recovery and long-term return improvement.
Key Considerations:
- Deposit Pipeline Execution: Success in converting the $1.5–2 billion pipeline to sticky, operating deposits is critical for margin and funding stability.
- Margin Sensitivity to Funding Mix: Wholesale and reciprocal funding remains expensive; improvement here is necessary for NIM recovery.
- Loan Portfolio Remix: Shrinking Resi and securities portfolios, with C&I growth, should support higher returns but may be slow depending on rate and economic conditions.
- Expense Discipline vs. Growth Investment: Management is prioritizing investments in producer teams and new geographies, with cost control focused on non-revenue areas.
- Buyback Suspension and Capital Accretion: Share repurchase remains paused, with capital expected to build until the macro and regulatory environment stabilizes.
Risks
BKU faces ongoing risks from funding cost volatility, especially if deposit pipeline conversion lags or market rates remain elevated. Further shifts in deposit mix toward interest-bearing accounts could prolong margin pressure. Regulatory changes may raise capital or liquidity requirements for regional banks. While the CRE portfolio is diversified and stress-tested, any macro downturn or sector-specific stress could elevate credit losses. Execution risk around talent onboarding and new market entry also remains.
Forward Outlook
For Q2 2023, BKU expects:
- Continued NIM pressure, with margin likely in the 250s if funding mix holds flat.
- Flat to modest loan growth, as C&I expansion is offset by Resi runoff and flat CRE.
For full-year 2023, management maintained guidance:
- Expense growth at the high end of prior mid- to high-single-digit guidance.
Management cited several factors affecting outlook:
- Deposit pipeline conversion and funding mix improvement are key to margin and earnings recovery.
- Loan growth will be relationship-driven, with a focus on C&I and core operating accounts.
Takeaways
Investors should recognize BKU’s deliberate pivot to a more resilient, relationship-driven deposit and lending model, but must weigh the near-term headwinds from margin compression and funding mix. The speed and quality of deposit pipeline execution and asset remix will determine the trajectory to targeted returns.
- Deposit Quality Over Quantity: Management’s refusal to chase back lumpy, non-strategic deposits signals a long-term shift to sustainable funding, but may slow near-term growth.
- Margin Recovery Hinges on Execution: NIM is under pressure until core deposit growth and funding mix improve, with wholesale reliance a key watchpoint.
- Balance Sheet Remix Pace Is Critical: The runoff of Resi and securities portfolios, and C&I growth, will dictate the timeline to normalized ROA and ROE.
Conclusion
BKU’s Q1 was a stress test of its deposit franchise, exposing vulnerabilities but also catalyzing a strategic reset toward core, relationship-based banking. Execution on deposit pipeline and asset remix will be the decisive factors for margin recovery and long-term value creation.
Industry Read-Through
BKU’s experience underscores the vulnerability of regional banks to sudden deposit outflows from institutional clients, especially during sector-wide crises. The rapid normalization of flows post-crisis, combined with management’s shift away from price-sensitive funds, highlights the industry-wide imperative to build granular, core-funded deposit bases. Funding mix and NIM pressure remain central themes for regionals, with capital and liquidity strength providing only partial insulation. Relationship banking and operating account focus are emerging as key competitive differentiators, while transactional or credit-only lending is being deprioritized. Other regionals should expect continued scrutiny of deposit composition, margin resilience, and the pace of balance sheet remixing as the sector recalibrates to a new funding and regulatory reality.
