Commonwealth Bank of Australia (ASX: CBA) has just given investors another look at the strength of its banking franchise.
For me, three parts of the business stood out from its FY26 result and support the long-term investment case.

A broad franchise
CBA's scale across Australian banking remains one of its biggest strengths.
The bank says it is the main financial institution for one in three Australians and one in four Australian businesses. During FY26, it also grew at or above the wider banking system across home lending, business lending, consumer finance, household deposits, and business deposits.
I think the range of that growth is particularly encouraging.
CBA has relationships with customers across everyday banking, savings, mortgages, credit cards, business finance, and investing. Those relationships give it plenty of opportunities to serve customers as their financial needs change over time.
A customer might begin with a transaction account before eventually taking out a home loan, opening an investment account, or starting a business.
The more products customers use, the deeper that relationship can become.
For me, this enormous customer base provides CBA with a strong foundation to keep growing alongside the Australian economy.
Business banking continues to impress
I also like what CBA is building in business banking.
Around one in four Australian businesses now considers CBA its main financial institution, and the bank continued increasing its share of business lending and deposits during FY26.
This gives CBA exposure to another large part of the economy.
Businesses need funding to buy equipment, expand premises, manage working capital, and pursue new opportunities. They also need transaction accounts, payment services, and other banking products to run their day-to-day operations.
CBA can build much broader relationships with these customers than simply providing a loan.
I think the bank's ability to serve businesses of varying sizes gives it a considerable opportunity as Australian companies grow and invest over the years ahead.
Its strong position in this market also complements the enormous retail franchise, giving CBA several avenues for long-term growth.
Technology remains a major strength
CBA has spent years building one of Australia's strongest digital banking offerings, and I think this remains an important competitive advantage.
The CommBank app sits at the centre of the relationship for millions of customers. The bank continues adding tools that help people manage spending, savings, home loans, investments, and other parts of their finances.
It is also pushing further into artificial intelligence. CommBank Companion is being developed to help retail and business customers interact with their financial information conversationally, while the bank is investing in AI across areas such as customer service, productivity, and fraud detection.
I think technology can help CBA make banking easier while strengthening customer relationships.
It can also improve how quickly the bank makes decisions and handles routine processes. For example, CBA says around 70% of proprietary home loan applications are now automatically decided on the same day.
Continuing to invest heavily in these capabilities could help CBA protect its leading position as customer expectations keep changing.
Foolish takeaway
CBA's FY26 result reinforced several of the reasons I like the business for the long term.
Its enormous customer franchise gives it plenty of opportunities to grow existing relationships, business banking continues to strengthen, and its technology investment could keep making the bank more valuable to customers.
Those are three qualities I would be happy to back for many years.
