In my
previous post, I invited investors’ attention to the impact of banking sector
underperformance on their portfolios and a need to carefully assess the challenges
being faced by the Indian banking sector presently, particularly from the
growth and valuation viewpoints.
The
following points, for example, make this review pertinent in my view.
At
first glance, the credit data is impressive. Bank credit grew at 16%
year-on-year to reach Rs 219 lakh crore as of March 31, 2026. Deposit growth
came in at 13.4% to reach Rs 267.8 lakh crore. The headline numbers are
healthy.
But
dig a little and the picture gets more complicated. As recently as mid-FY26,
the credit-deposit gap had widened to 263bps, with credit growing at 12% while
deposit growth slipped to just 9.35%. The credit-to-deposit ratio, which stood
at 53% in 2000-01, has now climbed to 82% — a multi-decade high. This means
banks are increasingly stretching their deposits to fund lending.
More
importantly, look at where the stress is building. Unsecured personal loans and
credit card borrowings, which had been growing at CAGRs of 22% and 25%
respectively in the three years to FY24, have slowed sharply — to 11% and 18% —
after the RBI tightened risk weights. That is the right policy move, but it
means the high-margin, high-growth engine of retail banking is now running at a
lower speed. Stress in unsecured retail loans accounted for roughly 52% of new
bad retail loans in the first half of FY25.
The
home loan market is stable and growing, but competition has crushed spreads.
Every major bank now offers floating rate home loans linked to the repo rate,
with 50–75 basis point cuts being passed on almost immediately. In the rush to
grow the mortgage book, margins on this segment are getting thinner every year.
Real
estate sector lending has picked up, but commercial real estate and
construction loans carry higher provisioning requirements under the Expected
Credit Loss (ECL) framework that banks are now transitioning to. This
transition is a key monitorable that the market seems to be ignoring.
Banking
is supposed to be an operating leverage play — as business grows, costs grow
slower, and profits grow faster. That story worked beautifully from 2020 to
2023. It is now becoming complicated.
Employee
costs remain sticky. The top private banks have been expanding branch networks
aggressively — including HDFC Bank’s massive post-merger expansion — and with
that comes increased headcount, salaries, and retirement benefit obligations.
Wage settlements with unions at public sector banks add another layer of fixed
cost increases every few years.
“Despite
a nearly five-times increase in information technology spending of banks over
the last decade, actual productivity gains for Indian banks have been just 1%.”
— BCG Report, August 2025.
The AI
and technology cost story is particularly worth examining closely. Banks are
spending heavily — the Indian banking sector’s IT spending is projected at
$14.5 billion in 2025. A BCG report noted that IT costs have grown at a CAGR of
17.4% over the decade to FY25, leading the pack in operating expense growth. In
other words, tech spending is rising fast, but the productivity payoff is still
modest.
Generative
AI adoption is now accelerating in earnest. Banks are deploying voice bots,
workflow automation, AI-powered credit underwriting, and fraud detection. The
EY-estimated productivity gain from GenAI is 34–46% by 2030 — a promise, not a
delivered result. Until then, banks must spend to build these capabilities. The
incremental IT capex through FY27–28 will be substantial before the savings
materialize. Think of it as a valley before a hill.
The
net effect: operating expense ratios are unlikely to compress meaningfully in
FY27. Margins from efficiency gains remain a story for later.
Indian
banks have done extraordinary work cleaning up their balance sheets. Gross
NPAs, which peaked at a distressing 11.2% in FY18, have fallen all the way to
2.0–2.1% by March 2026 — a near two-decade low. Net NPAs are at just 0.5%.
These are genuinely good numbers.
But
here is the investment catch: when you start from a place of historically good
asset quality, where exactly do you go from here?
Crisil
projects gross NPAs will be range-bound at 2.0–2.2% by March 2027. MSME stress
from global trade disruptions (including the West Asia conflict and US tariff
volatility) is already being flagged. The RBI’s own stress tests indicate NPAs
could inch back toward 3% in adverse scenarios. Recovery-driven earnings
tailwinds are now largely behind us.
For
years, banks benefited from lower credit costs — the money set aside for
potential loan losses. As NPAs fell, provisioning requirements fell with them,
giving a boost to profitability that was not really “operational” in nature.
That one-time tailwind from improving asset quality has now run its course.
Meanwhile,
the transition to Expected Credit Loss (ECL) norms — a more forward-looking
provisioning framework that the RBI is phasing in — means banks will be
required to set aside provisions for loans that are still performing but carry
elevated risk. This could require a meaningful one-time uplift in provisions
and suppress near-term profitability, even if banks’ underlying credit health
is fine.
In the
retail segment, stress from over-leveraged borrowers holding multiple unsecured
loans is clearly visible. Borrowers with three or more personal loans are
showing higher default rates. Credit cards outstanding and small ticket
personal loans — the highest-yield part of banks’ retail books — are also the
highest-risk segments today.
The
RBI has been on a rate-cutting cycle, with cumulative cuts of 125 basis points
in 2025 alone and further cuts likely in FY27. Lower rates are good for
borrowers and for credit growth — but they compress what banks earn on their
loan books.
NIMs
(Net Interest Margins — the difference between what a bank earns on loans and
what it pays on deposits) have already been under pressure. ICRA noted that the
December 2025 rate cut delayed NIM recovery to at least Q1 FY27. HDFC Bank’s
CASA ratio dipped to 34.14%, down from 34.79% last year — indicating that
cheaper deposits are getting replaced by higher-cost term deposits as savers
chase better rates from fixed deposits.
In
this environment, the NIM compression story is unlikely to reverse quickly.
Banks will see some relief as deposit repricing happens on the way down, but
this takes quarters to fully work through. Meanwhile, competitive pressure in
lending rates — especially in home loans and corporate credit — keeps
asset-side yields under check.
Simply
put: margins have seen their best levels. The next 12 months are likely to see
flat to marginally lower NIMs, which directly hits the profitability narrative.
Banks
have historically supplemented their interest income with a wide range of fees
— distribution of mutual funds and insurance, processing fees, forex income,
card-related charges, and the like. Many of these are now under regulatory
pressure.
UPI
transactions carry zero MDR — neither the merchant nor the bank earns a fee on
these. As UPI volumes have exploded into the billions of transactions per
month, this zero-MDR policy has effectively eliminated a significant revenue
pool. RuPay debit card transactions also carry no MDR. Banks absorb the
infrastructure cost of maintaining these payment networks without a
corresponding fee income.
There
is ongoing debate about whether a modest MDR should be introduced for
large-value UPI transactions. But the political economy of reversing zero-MDR —
a policy celebrated as a win for digital inclusion — is very difficult.
The
RBI has also been tightening the screws on mis-selling of insurance and
investment products, bancassurance practices, and customer fee disclosures.
Each of these tightening moves reduces the scope for high-margin fee income
that banks had been growing aggressively over the past decade.
This
is perhaps the most structural and underappreciated risk of all.
Think
back to the 1990s and early 2000s. ICICI Bank was known for project finance and
capital markets. HDFC Bank was the pioneer in salary accounts and consumer
banking. Kotak was the equipment financing specialist. Foreign banks like
Citibank dominated private banking and credit cards. Each institution had a
genuinely differentiated identity.
Now
visit the website or app of any of the top 15 banks. They all offer:
• Credit cards with airport lounge
access and cashback
• Personal loans in under 60 seconds
• Home loans at competitive floating
rates
• MSME loans with digital underwriting
• Savings accounts with high interest
rates (with conditions, of course)
• Mutual fund and insurance
distribution
• AI chatbots and digital-first
platforms
When
financial products are commoditized, the competitive edge shifts to cost of
funds, distribution scale, and brand trust — all of which tend to favor the
largest players and erode the pricing power and growth premium of mid-sized
private banks. The niche differentiations that once justified large private
banks trading at 4-5x their book value are rapidly disappearing.
The
AI/tech convergence is actually accelerating commoditization, not reversing it.
Every bank has cloud infrastructure. Every bank has a chatbot. Every bank has
instant loan disbursal. Technology was supposed to be the moat — instead, it is
becoming a minimum requirement, a table stake rather than a differentiator.
The
investment question then becomes: if banking is increasingly a commodity
business, why should private banks trade at 3x–4x price-to-book when global
banking peers trade at 1x–2x? The valuation premium is a legacy of the
differentiation era. As that era fades, so should the premium.
Bank
Nifty already underperformed Nifty during the period 2021 to 2024. The Nifty
Bank rose 41% from September 2021 to September 2024, against a 47% rise in
Nifty 50 — this despite banking sector EPS growing 135% versus 77% for Nifty
companies. Superior earnings, inferior stock performance. That is a classic de-rating
play book — the market awarded a lower multiple to the same rupee of bank
earnings.
The
setup for the next twelve months is similar, and in some ways worse:
• Earnings growth for banks is likely
to moderate as NIMs stabilize at lower levels and credit cost tailwinds dry up.
• The sectors most likely to outperform
Nifty — capital goods, infrastructure, pharmaceuticals, defence, new-age
technology — carry earnings growth visibility that banks simply do not have
today.
• Global tariff and trade uncertainty
disproportionately hurts MSME credit quality, a growing portion of bank books
• Regulatory tightening (ECL norms, fee
income restrictions, UPI zero-MDR) keeps compressing profitability without a
clear reversal in sight.
• The valuation premium for private
banks, while partially corrected, still has room to compress as commoditization
plays out.
To be
clear — I am not arguing that bank stock may correct sharply, or that their
fundamentals are broken. Indian banking is structurally sound. Credit demand is
real. NPA levels are the best in two decades. Capital adequacy is comfortable
at 17.24% system-wide. These are not the conditions for a banking crisis.
I am making
a narrower, more specific argument: the easy money in banking stocks has been
made. The sector is now priced for outcomes that will be hard to deliver. In a
market where capital flows will increasingly chase sectors with genuine
earnings acceleration — and banking might not be among them in FY27 — Bank
Nifty’s relative underperformance versus Nifty 50 is the most likely outcome.
Banking
stocks had their moment — and it was a good one. Clean balance sheets. Record
profitability. Massive re-rating. But each of those drivers has now run most of
its course.
What
lies ahead is a period where deposit growth lags credit, margins are flat at
best, AI spending front-runs the productivity savings, fee income is regulated
away, and the valuation premium for differentiation gets questioned because the
differentiation itself is fading.
If
you’re holding a Nifty index fund, you’re indirectly holding about 25–30% of
your money in banks and financial companies. That’s probably fine. But if
you’re actively overweight Bank Nifty or banking stocks relative to Nifty —
this might be a good time to ask yourself: what is the specific catalyst that
will drive banks to outperform from here?
I
failed to find a compelling one over the next twelve months.
