Executive Summary
Lower rates didn't lift bank profits—they compressed margins as deposit costs remained stubbornly high.
Cheap deposits are no longer abundant. Household savings are steadily moving towards mutual funds, insurance and other financial assets.
Private banks remain strong businesses, but higher funding costs have eroded the valuation premium investors once paid.
The next winners won't be the cheapest banks—they'll be those with durable deposit franchises, pricing power and disciplined capital allocation.

The Deposit War — A Shrinking Share of a Shifting Pie
Start with the counter-intuitive part. The RBI cut the repo rate by 125 bps through 2025 to 5.25%, then paused. Rate cuts are supposed to help banks. For India's private banks, they did the opposite, because of howtheir books are wired.
A large share of private-bank loans are floating and linked to the repo (external benchmark, or EBLR). When the RBI cuts, those loan yields reprice down almost immediately.Deposits, especially fixed deposits already booked at high rates, reprice down only slowly, with a lag of several quarters. So in a cutting cycle the asset side falls first and the liability side stays stuck, and the margin gets crushed in between.

Investor Insight - Rate cuts don't always boost bank profits. When loans reprice faster than deposits, the benefit initially goes to borrowers, not shareholders.

Key Takeaway
Banks are no longer competing only with each other. They are competing with mutual funds, insurance and every other financial product for the same household savings.

Margins have compressed, funding has become structurally more expensive and the premium valuation has followed.

The uncomfortable truth.
For the sector as a whole, the era of super-normal, cheap-CASA-fuelled RoEs is normalising toward global levels, which means the valuation convergence with JPMorgan is, largely, deserved, not a mispricing.
But there is another aspect – a positive Black Swan event.
Deposits Come Home
A sharp market correction could drive savers back to bank deposits. Lower deposit costs, stronger CASA and treasury gains would help restore bank profitability.
Weaker Rivals Exit
Aggressive lenders and weaker NBFCs are hit hardest in downturns, reducing competition and allowing stronger private banks to gain market share.
Survivors Take the Pie
Well-capitalised banks with strong deposit franchises emerge stronger after crises, driving earnings recovery and potential valuation re-rating.
05
Beneficiary — Franchise
ICICI-type deposit leaders
Low-cost CASA + fee/wealth income; defends RoA as margins normalise.
Beneficiary — Fee Engine
Banks with AMC / wealth / distribution arms
Monetise the SIP and insurance flows that drain deposits.
Turnaround Watch
HDFC Bank
Cheapest vs history, but needs delivered RoA; merger digestion near-term.
Caution — Wholesale-funded
Banks reliant on CDs / bulk deposits
Structurally higher cost of funds; margin-taker, not maker.
Caution — High Yield NBFCs
Unsecured / microfinance lenders
Credit-cost risk; first to crack in a downturn.
Macro Watch
RBI rate path
A pause repairs NIMs; fresh cuts delay the recovery.

Ametra’s Read
The world's best banks did not stop compounding because they became weaker—they stopped because their cheapest raw material, deposits, stopped being cheap. India's private banks now face a similar structural shift. While the current margin pressure should ease with the interest-rate cycle, the competition for household savings is unlikely to reverse. The next winners will therefore be defined not by how much their valuations have fallen, but by the strength of their deposit franchise, fee income and execution. The opportunity remains, but it is increasingly a story of owning the right banks—not simply owning the sector.
