Diamond Trust Bank Kenya is one of the NSE’s oldest and most understated counters: a Tier One regional lender with roots stretching back nearly eighty years, built by the Aga Khan Development Network into a quiet powerhouse of East African SME banking. Here’s the full picture.

History and Founding Story

Diamond Trust Bank’s origins trace back to 1945 and 1946, when it was established as Diamond Jubilee Investment Trust (DJIT), headquartered in Dar es Salaam, Tanzania, with branches in Mombasa, Kenya, and Kampala, Uganda.

The institution was founded as one of the earliest financial entities linked to the Aga Khan Development Network (AKDN), the development arm associated with the Aga Khan, spiritual leader of Shia Ismaili Muslims, and it grew alongside the East African Ismaili community’s broader economic development efforts across the region.

Over the following decades, the business evolved from an investment trust into a full commercial bank, and its Kenyan operation, Diamond Trust Bank Kenya Limited, was incorporated in its present form on 15 November 1998, building on the original 1946 institution.

The bank grew steadily under the long serving leadership of Group CEO Nasim Devji, who was appointed in 2001 and helped guide the bank through decades of expansion.

A major consolidation came in 2017, when Diamond Trust Bank Group acquired 100% ownership of Habib Bank Kenya, merging it into Diamond Trust Bank Kenya effective 1 August 2017.

That same period saw the bank open a new corporate headquarters, DTB Centre on Mombasa Road in Nairobi, inaugurated in 2014 by Prince Rahim Aga Khan.

Today, under the leadership of Chairman Linus Gitahi and CEO Murali Natarajan, DTB describes itself as celebrating an “80 year legacy” as a leading Tier I banking franchise in East Africa.

Core Business Lines / Revenue Streams

DTB positions itself around a clear strategic focus: SME banking, ecosystem lending, and digital expansion, backed by a growing regional retail and corporate base.

• SME and trade finance banking (the core engine): DTB has built its brand around serving small and medium sized enterprises, positioning itself strategically within SME and trade corridors across Kenya, Uganda, and Tanzania, a focus reflected in the bank’s marketing and lending priorities.
• Retail and corporate banking: Standard offerings including loans, savings and checking accounts, mortgages, debit and credit cards, and electronic funds transfer services for individuals and businesses across its East African markets.
• Digital and agent banking: DTB has invested heavily in digital transformation as one of the three pillars of its “DTB 3.0” strategy (alongside customer reach and sustainability), running country specific digital lending products such as Kwasa Kwasa in Uganda and Mgodi in Tanzania, aimed at retail and MSME customers, supported by a network of over 4,800 agents.
• Regional banking network: Beyond Kenya, DTB operates in Uganda, Tanzania, and (through the wider DTB Group) Burundi, with a combined network of more than 150 branches. Group customer numbers grew sharply, up 44% year on year to 5.9 million as of mid-2026, reflecting an aggressive push into new customer segments.

Competitive Position in Its Industry

Diamond Trust Bank sits among Kenya’s recognised Tier One banks, though it operates at a noticeably smaller scale than the sector’s largest players like Equity and KCB.

Its total assets reached roughly KSh659 billion by the end of 2025, up 15% year on year, positioning it as a solid mid to upper tier institution rather than a market leader by size.

What differentiates DTB competitively is its consistency and its niche focus.

The bank has posted steady, often double digit profit growth in recent periods (profit after tax up 21% to KSh10.7 billion for full year 2025, with net interest income up 24% as deposit costs fell alongside easing interest rates), a track record that has made it a favourite among investors who prize stability over aggressive growth.

Its historical focus on SME and trade finance banking, rather than chasing the same mass retail customers as Equity or KCB, has given it a somewhat distinct competitive lane, reinforced by its AKDN affiliation and long standing relationships with institutions like the International Finance Corporation (part of the World Bank Group), with which it has collaborated on regional development finance.

Ownership Structure

DTB is privately founded and remains closely held relative to many of its NSE listed peers, with the Aga Khan Development Network and its affiliated institutions continuing to hold significant influence over the bank even decades after listing.

• Aga Khan Fund for Economic Development (AKFED): The largest shareholder, holding around 16.5% of the company, reflecting the bank’s origins as an AKDN affiliated institution.
• Habib Bank Limited: A major shareholder holding around 16.1%, a legacy of DTB’s long standing collaborative relationship with Habib Bank of the Aga Khan Fund for Economic Development network, further deepened after the 2017 Habib Bank Kenya merger.
• Jubilee Holdings Limited: Another significant shareholder, at around 9.95%, reflecting a broader web of cross ownership among AKDN linked institutions in East Africa (Jubilee Insurance also shares AKFED as a common shareholder).
• Institutional and public shareholders: The remainder is split between foreign institutional investors (such as Norges Bank Investment Management and Conifer Management), local institutions, DTB’s own Employee Share Ownership Plan, and a broad general public shareholding of just over half the register.

Why It’s Listed on the NSE Specifically

DTB’s shares have been listed on what is now the Nairobi Securities Exchange for decades, making it one of the longer standing counters in Kenyan banking, alongside its Group’s cross listings on stock exchanges in Uganda and Tanzania, reflecting the bank’s genuinely regional, multi country structure.

The listing has functioned as a way for DTB, a bank whose ownership and management remain closely tied to the Aga Khan Development Network and a relatively small group of long standing institutional shareholders, to still access public capital markets and subject itself to the disclosure, governance, and capital adequacy standards required of a listed Tier One bank.

Its NSE listing has also given Kenyan and regional investors direct access to a bank whose growth strategy deliberately differs from the mass market, high volume approach of some of its larger listed peers, instead emphasising SME lending, ecosystem banking, and steady, disciplined profit growth.

Current Stock Price

As of September 11, 2026, Diamond Trust Bank Kenya’s share price stood at around KSh185.25, having pulled back 2.50% on the day.

The stock has had a strong run over the past year, climbing from a 52 week low near KSh75.00 to a high of KSh170.00 and beyond, roughly doubling in value, supported by strong earnings growth (earnings per share rose to KSh33.65 for 2025, up from KSh27.33 the year before) and falling deposit costs as Kenyan interest rates eased through 2025 and 2026.
