The digital edge in small-business banking
Banking | Digital
September 30, 2025 – Micro-, small, and medium-size enterprises (MSMEs) represent a crucial and growing market for banks, as they represent 90 percent of all companies and more than a fifth of global banking revenue pools. But banks face stiff competition from digital-first entrants and integrated software vendors that offer convenience and speedy services, note Partner András Havas and coauthors. Traditional banks that rely on manual processes and fragmented coverage models risk leaving MSMEs underserved. Banks can strengthen their market position by, for instance, prioritizing the digitization of the customer journey and offering data-driven recommendations and hyperpersonalized outreach campaigns.

Visual form
Stacked bar chart paired with a stacked share chart and a CAGR callout list.
Layout / body structure
The chart is a two-part layout read left to right. The left half shows total global banking revenues by segment across four years, the center lists CAGR values for each segment, and the right half shows the segment mix as 100 percent stacked bars.
What is being compared
It compares global banking revenues for retail, large corporations, and small and medium-size enterprises from 2019 through 2024, then compares how much of the total revenue pool each segment represents in each of those years.
Measurement system
The left chart uses dollars in trillions, the right chart uses percentage share, and the center labels give CAGR percentages for 2019 to 2024. The color scheme stays consistent across both charts so the same segment can be tracked through totals, growth, and mix.
Visible structure inside the graphic
The left panel uses stacked vertical bars for 2019, 2021, 2023, and 2024, with each bar divided into retail, large corporations, and MSMEs. Thin connector lines trace the rising top of each segment between years. The middle column lists CAGR values of 6, 6, and 7. The right panel repeats the same colors in 100 percent stacked bars labeled 52, 28, 20 in 2019; 53, 26, 21 in 2021; 52, 28, 20 in 2023; and 52, 28, 21 in 2024.
Main takeaway from the visual
The visual shows that MSME banking is growing fastest while still remaining a smaller slice than retail or large-corporate banking. Total revenue pools rise across all three segments, but the fastest growth sits in the light-blue MSME layer.
Key standout values or extremes
Total global banking revenues rise from 4.27 trillion dollars in 2019 to 5.77 trillion in 2024. Retail remains the largest segment at about 52 percent of the mix, large corporations stay near 26 to 28 percent, and MSMEs hold around one-fifth of the pool while posting the highest CAGR at 7 percent.
