Understanding Kenya’s Banking Market Share Rankings
The Central Bank of Kenya does not rank commercial banks using total assets alone.
It uses a weighted composite index that considers five important measures:
- Net assets: The total value of a bank’s assets after accounting for relevant liabilities.
- Total deposits: The money held by customers in bank accounts.
- Capital and reserves: The financial resources available to support the bank and absorb losses.
- Deposit accounts: The number of customer deposit accounts.
- Loan accounts: The number of customer loan accounts.
The CBK uses these indicators to classify banks into three peer groups.
| Bank Category | Market Share Index | Number of Banks in 2025 |
|---|---|---|
| Large banks | 5% and above | 8 |
| Medium banks | 1% to below 5% | 11 |
| Small banks | Below 1% | 20 |
The eight large banks controlled a combined 69.7% of the market in December 2025. Medium banks accounted for 23.2%, while small banks held 7.1%.
This shows that Kenya’s banking industry has a high level of concentration among its largest institutions.
The Size of Kenya’s Banking Industry
Kenya’s banking sector continued to grow in 2025.
According to the CBK Bank Supervision Annual Report 2025, the industry recorded the following figures:
| Banking Sector Indicator | December 2025 |
|---|---|
| Total commercial banks | 39 |
| Total net assets | KSh 8.35 trillion |
| Total deposits | KSh 6.385 trillion |
| Capital and reserves | KSh 1.404 trillion |
| Industry profit before tax | KSh 306 billion |
| Market share of large banks | 69.7% |
| Market share of medium banks | 23.2% |
| Market share of small banks | 7.1% |
Total banking sector net assets increased from KSh 7.568 trillion in December 2024 to KSh 8.35 trillion in December 2025.
This represented growth of approximately 10.3%.
The increase shows the important role of banks in supporting household finances, business investment, government activities, and economic development.
