CBK List of Banks With the Cheapest Banks
Citibank N.A. Kenya is the most affordable lender, with an average lending rate of 10.52 percent as of August 2025.
This rate is nearly five percentage points below the market average, offering a considerable advantage to corporate clients and high-value borrowers, who form Citibank’s primary customer base.
On the other hand, Stanbic Bank Kenya ranked second with an average rate of 11.94 percent, while Standard Chartered Bank Kenya came in third at 12.33 percent.
Guaranty Trust Bank (GTBank) and Ecobank rounded out the top five cheapest lenders, with rates of 12.91 percent and 13.44 percent, respectively.
On the deposit side, Stanbic also stood out for savers, offering the highest average return of 7.70 percent. Citibank paid 7.56 percent, while Gulf African Bank, Prime Bank, and Standard Chartered all posted 7.50 percent, offering competitive choices for depositors seeking to grow their savings.
Banks With the Most Expensive Loans
On the other hand, borrowers at Credit Bank and Access Bank (Kenya) PLC faced the highest costs.
Credit Bank had the highest average lending rate at 19.87 percent, while Access Bank was close behind at 19.52 percent. These figures are nearly double what Citibank charged, showing the difference in the credit market.
Middle East Bank, Commercial International Bank (CIB) Kenya, and SMEP Microfinance Bank also ranked among the most expensive, with lending rates averaging above 18.70 percent in August.
For many small businesses and individual borrowers, these high costs could limit access to credit and increase the risk of default.
Deposit rates at the expensive lenders were less attractive, with some banks paying under 7 percent, making them less competitive for savers.
Smaller and regional banks often price loans higher to offset perceived risks, limited capital bases, and narrower customer pools.
