India’s banking sector just printed a headline number that should have investors paying attention: systemic credit growth hit 17.7% year-on-year in the latest fortnight — a ten-year high. On the surface, that looks like an unqualified positive for the sector. Look underneath, and the picture is considerably more nuanced.
PSU Banks Are Eating Private Banks’ Lunch
The market share data tells a story that hasn’t fully registered in equity valuations. In home loans, private banks have lost nearly 15 percentage points of market share over four years — from 42.6% in FY22 to 28.1% in FY26. PSU banks have gone the other way, climbing from 34% to 45% over the same period. Auto loans paint a similar picture: private banks have ceded roughly 11 percentage points, falling from 38.1% in FY22 to 26.8% in FY26, while PSU banks have gained ground steadily, rising from 32.5% to 38.9%.
The mechanism is price. PSU banks are offering home loans at 7.10–7.25% and auto loans at around 7.75% — rates that private banks, with their higher cost structures and more expensive deposit franchises, cannot match without destroying margins. The result is a classic volume-for-margin trade: PSU banks are winning the business, but they are winning it at rates that compress their own net interest margins.

This is not a temporary promotional push. It reflects a structural shift in how PSU banks are deploying their balance sheets. Lower credit-to-deposit ratios give them more room to lend aggressively. CRR and SLR buffers are more comfortable. And with asset quality at multi-year bests — gross NPAs at systemic lows — the risk appetite is high. PSU bank managements are clearly making a strategic choice: sacrifice some margin to lock in market share while the cycle is favourable.
For private banks, the challenge is real. These are not peripheral product lines — home loans and auto loans are the secured lending backbone of retail franchises. Losing share in these segments doesn’t just compress revenues today; it weakens the cross-sell engine that drives fee income, insurance distribution, and long-duration customer relationships. The private banks that built their competitive moat on superior underwriting and distribution now face an environment where their government-owned competitors are simply undercutting them on price.
Set against this competitive backdrop is the broader credit cycle, which is running hotter than it has in a decade. Systemic loan growth at 17.7% is well above the ten-year mean of roughly 11.2%. The demand drivers are broad-based — retail, MSME, and a pickup in industrial and corporate borrowing are all contributing.
But here’s the tension: deposit growth continues to lag, running in the low-to-mid teens at around 12.2%. That loan-deposit growth gap — roughly 550 basis points — is widening, not narrowing. When credit grows materially faster than deposits for an extended period, the funding arithmetic forces banks into uncomfortable choices. Either they slow lending, or they pay up for deposits through higher term deposit rates, certificates of deposit, and wholesale borrowing. Most are choosing the latter, which shows up as margin pressure across the system.
This funding gap isn’t new, but its persistence is becoming a structural feature rather than a cyclical blip. Banks are competing for a share of the household savings pool that is shrinking relative to the credit demands of a fast-growing economy. That competition shows up directly in the cost of funds, and from there, in NIM trajectories.
The Investor’s Dilemma
The banking sector sits at an interesting juncture. Credit growth at a decade-high is unambiguously positive for the economy and, over time, for bank earnings. But the quality of that growth matters. PSU banks are gaining share through aggressive pricing that pressures their own margins. Private banks are defending profitability but losing the volume war in key secured lending segments. And the entire system faces a deposit growth challenge that constrains the pace at which credit expansion translates to earnings growth.
What makes this particularly relevant for large-cap equity investors is that these dynamics are not evenly distributed. The banks best positioned to navigate this environment — those with diversified funding bases, strong deposit franchises, and the ability to shift product mix toward higher-yielding segments — will separate from the pack. The ones relying on rate-driven volume growth or facing persistent deposit headwinds will find their earnings trajectory harder to sustain.
Where This Takes Us
Structural shifts in market share, funding dynamics, and competitive positioning don’t resolve in a quarter. They play out over cycles — and the investors who identify those shifts early, before they are fully reflected in earnings and multiples, are the ones who compound capital most effectively.
