Customers Bancorp (CUBB) — supplier relationships and what they mean for investors

Customers Bancorp operates as a progressive bank holding company that monetizes through net interest margin on lending (commercial real estate, mortgages, and commercial loans), fee income from treasury and payments services, and scale-driven deposit gathering via branch and digital channels. The firm expands its product set and accelerates time-to-market through third-party technology and payments partners while funding growth with a mix that includes long-term Federal Home Loan Bank (FHLB) and Federal Reserve advances. For readers evaluating supplier counterparty risk or partnership value, the payments relationships with Tassat/TassatPay are the most visible external technology tie-ins publicized to date.

How Customers Bancorp uses suppliers to extend its franchise

Customers Bancorp has structured its operating model to lean on third parties for both product innovation and back-office scale. Company disclosures and program descriptions make three operational characteristics clear:

• Outsourced core technology and processing functions: Customers leases and outsources major functions including data processing, loan servicing, deposit processing and money transfer systems to third-party service providers, which accelerates product rollout but concentrates operational risk with those vendors. (Company filings, FY2024–FY2025 disclosures.)
• Leasing posture for real estate: The bank leases its corporate and branch footprints from third parties rather than owning all real estate, creating predictable occupancy cost profiles but adding a counterparty exposure to landlords. (Customer disclosures on leased corporate and branch properties.)
• Long-term funding elements in the balance sheet: The company uses long-term FHLB and FRB advances as a stable funding sleeve, indicating a deliberate contracting posture for multi-year funding commitments rather than purely short-term wholesale reliance. (Long-term advances disclosures at December 31, 2024 and 2023.)

Collectively, these signals show a partnership-first operating model: Customers Bancorp trades some direct control for speed and capability through external vendors. That posture produces faster product launches plus vendor concentration risk and third-party operational criticality that investors must watch.

Why the Tassat relationships matter to the economic story

Customers has publicly tied its instant-payments ambitions to Tassat’s blockchain-enabled platform. Instant payments are both a product differentiator and a source of deposit stickiness and fee income, so the Tassat relationship is strategically meaningful. If the Tassat integration scales, Customers will convert payments flows into a competitive deposit and fee engine; if the integration encounters operational issues, reputational and revenue impacts follow directly.

Relationship-by-relationship: the two public supplier links

• TassatPay — Customers Bank launched a "soft launch" of a real-time, blockchain-based payments service powered by TassatPay in mid-October as part of its instant-payments push, showing the bank is live-testing a blockchain rails solution to deliver real-time settlement to clients. According to FinTech Magazine reporting on the announcement in FY2022, Customers began the soft launch of the TassatPay-enabled service. (FinTech Magazine, reporting mid-October / FY2022: fintechmagazine.com article.)
• Tassat — Earlier reporting noted that Customers Bank will utilize the TassatPay platform, confirming the use of Tassat’s technology as the underlying vendor for the instant payments product rather than an in-house rails development. PaymentsJournal documented Customers’ selection of the Tassat platform in FY2021. (PaymentsJournal, FY2021: paymentsjournal.com.)

Operational constraints and what they signal about risk and resilience

Company-level constraint excerpts and program descriptions indicate the following signals for investors evaluating supplier counterparty and operational risk:

• Contracting posture — long-term funding commitments exist. The presence of long-term FHLB and FRB advances indicates deliberate, multi-year funding relationships that stabilize liquidity but also create contractual repayment or covenants exposure. This is a corporate-level funding characteristic, not tied to any specific vendor.
• Service delivery model — substantial outsourcing. Customers explicitly outsources major technology and processing functions; that increases vendor criticality and the need for strong third-party risk management and business continuity programs.
• Relationship maturity and stage — active and operational. The company describes outsourcing as a live element of operations, indicating these supplier links are active components of day-to-day service delivery rather than exploratory pilots.

These constraints are company-level signals that shape how you should underwrite counterparty concentration, downtime risk, and the potential impact to revenue and reputation if a key vendor has an outage.

Investment implications: upside drivers and risk checklist

• Upside drivers: Successful roll-out and scaling of the Tassat/TassatPay integration creates a differentiated instant-payments capability that can increase non-interest fee income and deposit retention while broadening treasury services to commercial clients. That aligns with the bank’s strategy to serve underserved markets via modern digital channels.
• Key risks: Heavy outsourcing increases operational concentration and fourth‑party exposure; leasing strategy exposes the firm to landlord performance; long-term advance usage can amplify interest-rate and covenant sensitivities. Operational and vendor-governance execution is the single most important risk variable.
• What to monitor: vendor SLAs and uptime history, incident disclosures tied to payments processing, evolution of fee-bearing transactions on the Tassat rails, and any regulatory or compliance notices involving third-party payment processors.

Final read: where to focus diligence

Customers Bancorp’s approach is a deliberate trade-off: external partnerships accelerate product delivery and scale but centralize operational risk with a narrow set of suppliers. For investors and operators, the Tassat/TassatPay linkage is the most visible supplier dependency and should be evaluated for operational performance and revenue conversion potential. Simultaneously, the company-level practice of broad outsourcing and the use of long-term advances require ongoing scrutiny of vendor governance and balance-sheet covenants.
