Sidian Bank has officially earned classification as a mid-sized bank in Kenya’s financial sector after a period of rapid expansion in assets, deposits and overall market presence. According to a communication from the Central Bank of Kenya, the bank met the regulatory thresholds for a Tier 2 institution at the end of September 2025, based on criteria such as asset size, total deposits, shareholder funds and account numbers. This marks the first time Sidian has risen above its former status as a small lender, positioning it alongside other mid-tier banks such as Family Bank, National Bank of Kenya and SBM Bank.
The upgrade to mid-sized lender reflects significant growth across key financial indicators. Sidian’s asset base grew to about KSh 94.8 billion by September 2025, up from approximately KSh 60 billion at the end of 2024, representing a notable increase in scale relative to the broader banking industry. During the same period, customer deposits rose sharply from KSh 45.7 billion to around KSh 78.1 billion increasing the bank’s share of total industry deposits to nearly 1.83 percent from 0.7 percent a year earlier.
Sidian’s momentum was supported by strategic capital injections through a rights issue aimed at raising KSh 3 billion, bringing total new equity raised over the past 18 months to about KSh 6 billion. This infusion of capital has strengthened the bank’s balance sheet and supported its drive toward higher regulatory capital thresholds expected of mid-tier lenders. Ownership has also diversified, with new investors entering as previous majority stakeholder Centum Investment Company reduced its position over time.
Growth in deposits and assets translated into strong profitability gains in 2025, with the bank’s after-tax profit expanding markedly compared to the prior year. While Sidian’s loan book has grown more slowly, a substantial proportion of new deposits has been invested in government securities and other low-risk instruments, contributing to earnings stability. The bank has also strengthened its leadership and governance structures as it transitions into this next stage of development.
The reclassification is likely to improve Sidian’s ability to attract larger corporate accounts, which often prefer banking with institutions that have broader capitalization and risk capacity. It also signals confidence among investors and depositors in the bank’s strategic direction and operational performance.
