The Reserve Bank of India (RBI) has officially approved Kotak Mahindra Bank Limited to acquire an aggregate holding of up to 9.99% in AU Small Finance Bank and Federal Bank Limited. This strategic move allows the Kotak Mahindra Group to expand its influence across well-established mid-sized and specialized banking players in the Indian financial market. The acquisition is subject to stringent regulatory compliance and aims to utilize the bank’s surplus capital for inorganic growth.
RBI Approval for Strategic Stake Acquisition
The Reserve Bank of India (RBI), through a formal communication on May 6, 2026, granted its approval to Kotak Mahindra Bank Limited (KMBL) for acquiring an aggregate holding of up to 9.99% of the paid-up share capital or voting rights in AU Small Finance Bank and Federal Bank Limited. This approval extends to the broader Kotak Mahindra Group, which includes the bank, its subsidiaries, and various funds or schemes managed by its arms.
The regulatory clearance follows separate applications made by Kotak Mahindra Bank to the central bank. The targeted lenders, Federal Bank and AU Small Finance Bank, subsequently confirmed the receipt of this approval through official stock exchange filings. The approval serves as a significant milestone for Kotak, allowing it to consolidate its position as a major institutional shareholder in these high-performing banks.
Understanding the 9.99% Regulatory Threshold
In the Indian banking sector, shareholding is strictly regulated by the RBI to ensure stability and prevent concentration of control. Under the Banking Regulation Act, 1949, any individual or entity seeking to acquire a 5% or more stake in a bank, known as a Major Shareholding, must obtain prior approval from the RBI. The central bank conducts a rigorous fit and proper assessment of the investor before granting such permission.
The specific limit of 9.99% is strategically significant. While the RBI allows non-promoter institutional investors to hold up to 10% in a bank, exceeding this threshold often triggers a more complex regulatory layer. This includes mandatory lock-in periods, typically for five years, and more exhaustive disclosures regarding the group structure. By capping the approval at 9.99%, Kotak Mahindra Bank gains substantial exposure and voting rights while remaining just within the primary tier of non-promoter shareholding limits.
Strategic Rationale for Kotak Mahindra Bank
Led by CEO Ashok Vaswani, Kotak Mahindra Bank has been proactively seeking inorganic growth opportunities to deploy its strong capital reserves. The bank’s capital adequacy ratio remains comfortably above regulatory requirements, providing it with the financial flexibility to make such investments. By acquiring stakes in Federal Bank and AU Small Finance Bank, Kotak is not necessarily aiming for a complete takeover but is rather securing a seat at the table of two of India’s most promising mid-market lenders.
This opportunistic investment strategy allows Kotak to benefit from the growth trajectories of these banks. Federal Bank has a strong presence in Southern India and a robust digital ecosystem, while AU Small Finance Bank is a leader in the specialized small finance banking segment with a deep reach in Western and Northern India. These investments could lead to future synergies in treasury operations, product distribution, or strategic partnerships.

Regulatory Framework for Bank Shareholding in India
The regulatory landscape for bank shareholding is primarily governed by Section 12B of the Banking Regulation Act, 1949. In November 2025, the RBI issued updated Master Directions titled ‘Commercial Banks – Acquisition and Holding of Shares or Voting Rights’. These directions provide a clear framework for various categories of investors:
- Non-Promoters: Can hold up to 10% of a bank’s capital. Higher limits of up to 15% are available for supranational institutions, public sector undertakings, and the Government.
- Promoters: Are generally required to cap their long-term shareholding at 26% of the paid-up equity.
- Approval Process: Any acquisition exceeding 5% requires the RBI to evaluate the integrity and financial standing of the applicant through the PRAVAAH portal.
The RBI’s focus remains on ensuring that banks are ‘widely held’ and that no single entity exerts disproportionate influence unless they are promoters with a long-term commitment. This regulatory caution is intended to protect the interests of depositors and maintain the overall integrity of the Indian banking system.
