City Union Bank Limited has informed stock exchanges that the Reserve Bank of India (RBI) has granted approval to Kotak Mahindra Bank Limited for acquiring an aggregate shareholding of up to 9.99% in the bank.

The development was disclosed by City Union Bank through a regulatory filing submitted to both the National Stock Exchange of India (NSE) and BSE Limited on May 7, 2026.

According to the filing, RBI issued the approval through a communication dated May 6, 2026.

The announcement has attracted market attention because strategic investments and stake acquisitions involving banking institutions are closely monitored by investors and regulators.

RBI Approval for Stake Acquisition

City Union Bank stated that the RBI has accorded its approval to Kotak Mahindra Bank Limited to acquire aggregate holding of up to 9.99% of the paid-up share capital or voting rights in the bank.

The approval was granted under applicable banking regulations and is subject to compliance with several legal and regulatory conditions.

The company’s filing clarified that the approval remains subject to adherence to:

• Banking Regulation Act, 1949
• RBI Directions on acquisition and holding of shares or voting rights
• Foreign Exchange Management Act, 1999
• SEBI regulations
• Other applicable laws and guidelines

The communication from RBI specifically referred to the Reserve Bank of India (Commercial Banks – Acquisition and Holding of Shares or Voting Rights) Directions, 2025.

Why the Development Is Important

Any investment or stake acquisition involving banking institutions generally attracts significant attention because the banking sector is heavily regulated.

Acquiring up to 9.99% stake in a bank is considered strategically important because:

• It may reflect investor confidence in the bank
• It can strengthen institutional relationships
• It may indicate long-term strategic interest
• It often influences market sentiment
• It requires regulatory scrutiny and approvals

In India’s banking system, shareholding beyond specified thresholds requires approval from RBI to ensure compliance with prudential norms and ownership regulations.

Understanding the 9.99% Threshold

The proposed acquisition allows Kotak Mahindra Bank to hold up to 9.99% in City Union Bank.

Under RBI norms, acquisition of substantial shareholding in banks is carefully monitored to ensure:

• Financial stability
• Proper governance
• Transparent ownership structures
• Prevention of excessive concentration of control
• Compliance with fit-and-proper requirements

The approval does not necessarily mean that the full 9.99% stake has already been acquired. Instead, it authorises Kotak Mahindra Bank to acquire shares up to the approved threshold, subject to compliance conditions.

Strategic Importance for Kotak Mahindra Bank

Kotak Mahindra Bank is one of India’s leading private sector banks with strong presence across:

• Retail banking
• Corporate banking
• Wealth management
• Investment banking
• Treasury operations
• Digital financial services

An approved stake acquisition in another banking institution could have strategic significance from multiple perspectives including:

• Financial investment
• Banking sector exposure
• Long-term strategic positioning
• Market opportunities
• Institutional collaboration possibilities

However, the filing does not specify the exact purpose or timeline of the proposed stake acquisition.

The Reserve Bank of India plays a critical role in regulating ownership structures in the banking sector.

Banking institutions are considered systemically important because they deal with:

• Public deposits
• Credit creation
• Financial stability
• Payment systems

Therefore, RBI approval is mandatory for significant shareholding acquisitions to ensure that ownership changes do not adversely affect banking stability or governance standards.

RBI evaluates multiple factors before granting approvals, including:

• Financial strength of acquirer
• Regulatory compliance history
• Governance standards
• Market implications
• Fit-and-proper criteria

FEMA Regulations

Foreign Exchange Management Act provisions apply where cross-border investment considerations arise.

SEBI Regulations

Market Perspective on Banking Investments

Strategic investments in banks are often evaluated carefully because banking institutions are highly sensitive to:

• Capital adequacy

• Regulatory compliance
• Shareholding patterns

Any change in institutional ownership can influence future market expectations.

However, investors generally wait for further details regarding:

• Actual acquisition timeline

before drawing long-term conclusions.
