Commercial banks and investment banks both play important roles in Kenya’s financial system but they differ significantly in functions, clientele, revenue models and regulation. These differences determine how each institution supports economic growth and responds to market conditions.
Commercial banks are the backbone of Kenya’s banking sector and are licensed and supervised by the Central Bank of Kenya (CBK) under the Banking Act. They accept deposits, provide loans to households and businesses and facilitate payments including electronic funds transfers and foreign exchange. As of 2025, Kenya has 38 licensed commercial banks including major players such as KCB, Equity Bank and Co-operative Bank, which together hold a large share of industry assets and customer deposits.
The sector’s economic significance is reflected in its profitability. According to a report by Kenya Bank Association, in 2024 Kenyan commercial banks reported a combined pre-tax profit of about KES 260.1 billion, driven by lending growth and operational efficiency. Their primary income comes from the interest rate spread between loans and deposits alongside fees for payments, trade finance, and account services. Due to their deposit-taking role, commercial banks are subject to strict capital and liquidity requirements to protect depositors and maintain financial stability.
Investment banks in Kenya operate mainly in capital markets and corporate finance rather than traditional lending. They are licensed and regulated by the Capital Markets Authority (CMA) under the Capital Markets Act, which ensures fair and orderly securities markets. According to the Capital Market Authority, there are 18 listed investment banks including notable ones such as Dyer & Blair, Equity Investment Bank and Faida Investment Bank. These firms provide services such as underwriting equities and bonds, brokerage, trading on the Nairobi Securities Exchange and advisory for mergers and acquisitions. Most of their revenue comes from fees and commissions on transactions rather than interest income.
Risk exposure also distinguishes the two. Commercial banks face credit risk from loan defaults and interest rate risk linked to macroeconomic changes. Investment banks are more exposed to market risk from securities price fluctuations and transaction risk associated with advisory deals. Regulation mirrors these differences as CBK oversight emphasizes depositor protection and systemic stability while CMA supervision focuses on market integrity and investor protection.
In conclusion, commercial banks in Kenya drive economic activity through deposits and credit while investment banks support capital formation and market efficiency. Their differing roles, income sources, risk profiles, and regulatory frameworks highlight the complementary nature of these institutions in Kenya’s financial system.
