Kotak Bank Gets RBI Nod for 9.99% Stakes in Three Mid-Banks

Kotak Bank's Triple Stake Play: What the RBI Approval Actually Means The Reserve Bank of India, in a communication dated May 6, 2026, approved [Kotak Mahindra Bank](/stock/KOTAKBANK) (NSE: KOTAKBANK) to acquire stakes of up to 9.99% each in [City Union Bank](/stock/CUB) (NSE: CUB), [Jammu & Kashmir Bank](/stock/J&KBANK) (NSE: J&KBANK), and [South Indian Bank](/stock/SOUTHBANK) (NSE: SOUTHBANK). Three approvals at once is not standard housekeeping. This is a coordinated positioning move, and markets will price it that way when trading opens Monday. A sub-10% stake keeps Kotak below the RBI threshold that triggers mandatory disclosure as a 'substantial acquirer' under takeover regulations — and below the level that requires prior approval for further acquisition in most cases.

City Union Bank (NSE: CUB) is a Kumbakonam-based lender with a tight MSME franchise in Tamil Nadu, trading at approximately 1.1x price-to-book as of its last close. South Indian Bank (NSE: SOUTHBANK) has been rebuilding asset quality after a rough 2021-2023 cycle and trades closer to 0.7x book — cheap by most measures, but cheap with reason given its legacy NPA overhang. J&K Bank (NSE: J&KBANK) is a different animal entirely: government-inf...
