Federal Bank: RBI clears Kotak 9.99% stake in 2026

Overview of the RBI approval

Federal Bank on Thursday said the Reserve Bank of India (RBI) has approved Kotak Mahindra Bank to acquire an aggregate holding of up to 9.99% in the private lender. If Kotak moves towards the permitted limit, it could become one of Federal Bank’s largest institutional shareholders. The approval is closely tracked because RBI clearances for shareholding in banks can signal a strategic intent even when the stake remains below control thresholds. The disclosure, however, leaves open key questions on how and when Kotak may build the position. The development comes amid tighter and more specific RBI directions on acquisition and holding of shares in commercial banks.

What Federal Bank disclosed to exchanges

In an exchange filing dated May 7, Federal Bank said it received an intimation from the RBI on May 6. The intimation granted Kotak Mahindra Bank approval to acquire up to 9.99% of the paid-up share capital or voting rights of Federal Bank. The filing did not state whether Kotak has already started accumulating shares. It also did not specify whether the acquisition would happen through open market purchases, block deals, or another route. As a result, the next set of shareholding disclosures will be important for investors tracking any movement towards the 9.99% ceiling.

Why the 9.99% threshold matters

The 9.99% level is significant in bank shareholding because it sits just below 10%, a line that typically attracts higher scrutiny and may require additional approvals. Federal Bank’s filing referenced the concept of “aggregate holding,” indicating the permitted limit applies to the total stake acquired under the RBI’s approval framework. Market participants often interpret such approvals as enabling flexibility to build a sizeable minority stake without triggering more stringent thresholds. At the same time, it does not, by itself, confirm that purchases will be executed immediately or in full.

Conditions attached to the approval

Federal Bank said the approval is subject to compliance with multiple regulatory frameworks. These include provisions under the Banking Regulation Act, 1949, and the RBI’s Commercial Banks – Acquisition and Holding of Shares or Voting Rights Directions, 2025. The bank also cited foreign exchange regulations, Sebi rules, and other applicable laws. The explicit list of conditions underlines that even minority stake-building in banks is governed by layered requirements covering ownership limits, disclosures, and the manner of acquisition.

Unknowns: route and timing of share purchases

A notable gap in the exchange filing is the absence of details on the acquisition route. The bank did not disclose if Kotak has already acquired any shares in Federal Bank or whether purchases will be staggered over time. It also did not state whether the stake would be built via on-market buying, negotiated transactions, or other structures. Because such moves can influence liquidity and trading patterns, investors typically watch for subsequent disclosures that clarify the pace and method of accumulation. For now, the approval functions as a regulatory green light rather than a confirmed transaction schedule.

Parallel approval for AU Small Finance Bank

Separate disclosures referenced that the RBI has also permitted Kotak Mahindra Bank to acquire up to 9.99% in AU Small Finance Bank (AU SFB). AU SFB’s filing stated that Kotak Mahindra Bank Ltd, along with its subsidiaries and the funds or schemes managed by those subsidiaries (collectively referred to as the “Kotak Mahindra Group”), received approval to acquire an aggregate holding up to 9.99% of AU SFB’s paid-up share capital or voting rights. The same reporting also noted that both AU SFB and Federal Bank acknowledged receipt of the approval letter dated May 6.

Early market reaction and what investors will track

Reports described the market reaction as mild. In early trade referenced in the material, AU Small Finance Bank was seen trading at ₹1,021.60 on the BSE, down 0.18% (₹2.85), while Kotak Mahindra Bank was seen at ₹379.35, up 0.84% (₹3.15). Beyond price moves on the day, investors are likely to focus on periodic shareholding pattern updates to see whether Kotak moves quickly towards the permitted threshold. In addition, the market will watch whether the stake-building is accompanied by any further regulatory communication or strategic disclosures.

How RBI shareholding rules shape bank stakes

The RBI’s shareholding approvals are closely watched when one large private sector bank seeks to build a stake in another listed lender. Even when the stake is capped at 9.99%, approvals can affect investor expectations around long-term partnerships, strategic investment intent, or portfolio positioning. However, Federal Bank’s disclosure did not indicate any strategic agreement, board role, or operational linkage. It simply communicated that the RBI has granted permission, subject to compliance, for holding up to the specified limit.

Kotak’s broader compliance and group-structure moves

Separately, Kotak Mahindra Bank has said it will streamline its group structure by bringing the business of its wholly owned subsidiary, Kotak Mahindra Investments Limited (KMIL), within the bank from April 1, 2026. The bank said the move is aimed at complying with the RBI’s Commercial Banks – Undertaking of Financial Services Directions, 2025. It also said the transition would result in KMIL’s business activities being conducted departmentally within Kotak Mahindra Bank going forward. While this is distinct from the stake approvals, it reflects the broader compliance context in which banks are aligning structures and investments with updated RBI directions.

Key facts at a glance

What comes next

The next set of shareholding disclosures will be the main source of clarity on whether Kotak has begun building a position in Federal Bank and at what pace. Investors will also watch for any further updates that explain the acquisition route or any additional regulatory steps if holdings approach key thresholds. For AU SFB, market participants will similarly look for changes in disclosed holdings by Kotak Mahindra Bank and its group entities. For now, the filings establish the RBI’s permission framework, while the execution and timing remain to be seen through subsequent disclosures.
