Business Model & Revenue Streams
The four-pillar universal-bank architecture, the revenue streams across net interest income and fees, and the unit economics and digital cost advantage.
5.1 Four-Pillar Universal Bank Architecture
OptimaBank is structured around the four-pillar architecture proven
by large African universal banks, integrated on a single platform and
shared customer data layer:
- Personal & Private Banking (PPB): Personal
accounts, transactional banking, savings, home loans, credit cards,
unsecured lending and digital wealth. - Business & Commercial Banking (BCB): SME and
mid-market working-capital finance, merchant services, asset finance,
trade finance and embedded digital business tools. - Corporate & Investment Banking (CIB):
Large-corporate and government financing, infrastructure and project
finance, trade and commodity finance, and markets / treasury — typically
the highest-revenue segment for African universal banks. - Insurance & Asset Management (IAM): Life and
short-term insurance, retirement and pension products, investment and
asset-management services and wealth structuring.
5.2 Revenue Streams
OptimaBank generates revenue across four principal streams, balancing
capital-intensive net interest income with capital-light fee and
commission income:
- Net interest income (NII): Interest earned on
retail, SME, corporate and mortgage lending, net of funding cost — the
core engine of the bank. - Fee & commission income: Transaction and
payment fees, merchant and card interchange, FX spreads and payment
processing. - Corporate & investment banking income:
Structured finance, advisory, trade-finance fees and capital-markets
income. - Insurance & wealth income: Insurance
premiums, investment-advisory fees and asset-management fees.
The build-up of total operating income across the planning horizon,
split between net interest income and non-interest revenue, is shown
below. Non-interest revenue rises from approximately 62% of NII in Year
1 to roughly 82% by Year 5 as the transactional, CIB and insurance
franchises mature — evidencing a diversified, resilient revenue mix.
5.3 Unit Economics & Cost Advantage
The economic heart of the model is a structurally low cost-to-serve.
By automating onboarding, servicing and credit decisioning on a
cloud-native core, OptimaBank targets a mature-state cost-to-income
ratio of approximately 49% — below the incumbent major-bank average. In
the early years this ratio exceeds 100% as fixed platform and
acquisition costs precede revenue scale; it then falls rapidly as income
compounds against a largely fixed cost base, driving operating leverage
and rising returns on equity.
