Something big is happening in the boardrooms of South Africa’s largest banks, and it has nothing to do with retail customers or home loans. The country’s most powerful lenders are quietly pivoting their growth strategies toward a segment they once overlooked: medium-sized companies. And the prize on the table is enormous.
Faced with growing competition for large corporates and squeezed retail banking margins in a sluggish economy, lenders including Nedbank, Investec, FirstRand’s First National Bank and Standard Bank are targeting the mid-corporate sector with dedicated teams and tailored services. This market covers companies with annual revenue of R100 million to around R1.5 billion, spanning sectors from manufacturing and mining services to agriculture, retail and logistics. These are not startup ventures or informal businesses. They are established, revenue-generating companies that form the backbone of South Africa’s productive economy.

The reason banks are scrambling for this segment comes down to one compelling number. Standard Bank estimates that Africa’s mid-corporate segment represents a potential revenue pool of R150 billion, with 85% of that concentrated in South Africa, Nigeria, Ghana, Kenya, Uganda and Tanzania. That is not a figure any serious financial institution can afford to walk past, and none of the big players intend to.
Bank executives say these businesses are often cash-rich, fast-growing and steadier, and provide more attractive returns than more volatile retail and small business portfolios. Mid-corporate clients tend to maintain larger deposits, require more complex financial products, and generate steadier fee income across treasury, trade finance, and business transactional services.
For Standard Bank, Africa’s largest lender by assets with around 28% of South Africa’s mid-corporate market, the opportunities extend beyond the continent’s most industrialised economy.
Bill Blackie, the bank’s chief executive of Business and Commercial Banking, signaled at the March capital markets day that the mid-corporate push is not just a domestic play but a pan-African growth strategy. “Today our customers trade more across the continent than they do with any other single trade bloc, be it China or the U.S.,” Blackie told Reuters. The bank is targeting deposits above R725 billion by 2028 in its business and commercial banking division, up from R514 billion in 2025.
Nedbank is not standing still. “This is a strategic growth vector for Nedbank. We’re scaling the operation,” Marlon Davids, the head of mid-corporate coverage at Nedbank’s Business and Commercial Banking unit, told Reuters. The bank has created a dedicated mid-corporate unit with its own credit committees and commercial bankers, targeting up to 30% of South Africa’s estimated mid-corporate client base. Giving the unit its own credit committees is a deliberate move to speed up decision-making and offer more tailored lending terms to businesses that often found the big banks too slow or too rigid to work with.
FNB is approaching the opportunity differently. The bank, which already serves over 20,000 medium-sized companies, combined its mid- and large corporate client units into a single division in March, allowing it to sell more sophisticated banking products to fast-growing firms and retain clients as they scale.
The timing of all this is not accidental. South Africa’s five biggest lenders raked in nearly R150 billion in combined profits in 2025, a year that signaled a genuine turnaround in sentiment towards the economy. With balance sheets strengthened and a more optimistic outlook following the country’s removal from the Financial Action Task Force grey list, the banks now have both the appetite and the firepower to compete aggressively for new growth segments.
The mid-corporate segment is fragmented, underserved, and sitting on a revenue pool that few banks bothered to quantify until now. The intensifying competition is likely to benefit medium-sized businesses directly, with companies in this bracket set to enjoy more competitive pricing, faster credit approvals, and access to products previously reserved for larger clients.
The gold mine is R150 billion. The race has already started, and every major bank in the country wants a share of it.
