The NIM Squeeze Spreads — Public Sector Banks Confirm Deposit-Cost Pressure
Six days of Q1 results reveal the deposit-cost compression story extends beyond large-caps to PSU banks and housing finance companies.
The deposit-cost story that emerged from large-cap bank results in early July has deepened. Within 72 hours last week, four systemically important PSU and mid-tier banks reported Q1 FY27 earnings that collectively underscore a sector-wide squeeze on net interest margins — even as profit growth headlines mask the underlying pressure. Punjab National Bank's standout +213.6% PAT growth, Punjab & Sind Bank's +23%, IDBI's +5%, and Can Fin Homes' +20% tell a tale of two forces working in opposite directions: a release of loan-loss provisions on the upside, but compression of spreads on the downside.
The outlier profit growth is not margin expansion—it's the release of pandemic-era provisions. The real story is what happens next, when that tailwind fades.
PNB Declares Q1 FY27 Results: Profit Surges on Provision Release
Punjab National Bank's net profit soared 213.6% year-on-year to ₹5,253 crore in Q1 FY27, driven largely by a material release of provisions. Global business grew 10.2% to ₹29.98 lakh crore, deposits rose 8.5%, and advances climbed 12.7%. Gross NPA ratio improved to 2.78% and net NPA to 0.28%.
Read:The exceptional profit growth masks underlying margin pressure. While the bank's size and capital cushion provide buffer, the magnitude of provision release—not operating leverage—is the key driver. Watch for NIM data in the full results filing.
BSE FilingPSB Reports Q1 FY27: Growth at 23% on Lower Provisions, Margin Pressure Visible
Punjab & Sind Bank's standalone net profit rose 23% year-on-year to ₹332 crore. Gross NPA fell to 2.21%, creating provision headroom, but deposit growth competed with loan growth, signaling rising funding costs in a tight liquidity environment.
Read:A mid-sized PSU bank's 23% growth is respectable but tempered by the deposit-cost dynamics visible in the business mix. The GNPA improvement is genuine, but margin expansion did not keep pace with profit growth—consistent with the sector narrative.
BSE FilingIDBI Bank Q1 FY27: Profit Growth Lags at +5%, Headwinds Pronounced
IDBI Bank's net profit grew only 5% year-on-year to ₹2,115 crore—the slowest of the four. While asset quality improved and provisions were rationalized, the lagging profit growth reflects IDBI's tighter margins and structural cost pressures. Loan growth remained in low-single digits as the bank prioritized quality.
Read:IDBI's muted 5% growth signals the limits of the provision-release tailwind. A bank with a smaller deposit base and higher cost of funds faces margin compression without offsetting profitability gains. This is a cautionary signal for other smaller PSU banks.
BSE FilingCan Fin Homes Q1 FY27: Housing Finance Sector Confirms Deposit Pressure
Can Fin Homes' net profit rose 20% year-on-year to ₹268 crore. The housing finance company's results highlight the broader sector trend: lending growth continues, but deposit costs and competitive disbursement rates are squeezing net interest margins and return on assets.
Read:Can Fin Homes' 20% profit growth masks the operational reality that the company is competing fiercely for retail deposits while loan pricing has flattened. For HFCs, which rely on low-cost deposits, this is a structural profitability headwind. The 20% headline hides cautionary margins beneath.
BSE FilingThe July 13 report, "Cheap Money Is Gone," established the deposit-cost compression story for large-cap banks (HDFCBANK, Kotak, Axis). The provision-release tailwind there was visible, but so was the NIM squeeze. This week's PSU and mid-tier results confirm the pattern is neither isolated nor temporary. Four banks across three tiers of the financial system all reported profit growth that outpaced operating leverage—a classic sign of provision release propping up headline numbers while underlying spreads narrow.
In a rising-rates environment, deposit costs have climbed faster than lending spreads. Retail deposits—the lifeblood of PSU banks and HFCs—now carry higher term premiums. Corporates can access wholesale funds; retail customers shop for the highest savings rates. Banks are forced to compete on price or accept slower deposit growth, throttling loan origination. Either way, the NIM contracts.

Years of Monetary Tightening LaggingBoth PNB and IDBI benefited from material provision reversals as COVID-era stress evaporated. This is real—non-performing assets have genuinely improved—but it is not repeatable. As the NPA cycle normalizes, the provision tailwind will fade. When it does, profit growth will depend entirely on operational leverage: either expanding NIMs or cutting costs. Given deposit competition, NIM expansion is unlikely. Cost pressures (technology, compliance, employee wages) are rising, not falling.
Profit growth rates and asset quality improvements reflect both provision normalization and operational performance. Deposit-cost pressures are not fully visible in headline profits.
nim_compression
PNBNIM trends in full results — Watch the Net Interest Margin (NIM) or spread metrics in consolidated filings. If NIM is flat or negative YoY despite healthy loan growth, the margin squeeze is confirmed. Target: NIM should widen in a falling-rate environment; stagnation signals structural deposit pressure.
deposit_growth
CFHLDeposit growth vs. loan growth — The next test is Q2 business figures. If deposit growth consistently lags loan growth (or slows materially), banks will face funding constraints or must pay more for deposits. PSU banks and HFCs are most vulnerable here.
rate_cuts
RBI rate-cut timeline — A sustained easing cycle could ease deposit pressure, but transmission to NIMs depends on how quickly banks lower lending rates. Early easing could even accelerate NIM compression if deposit rates fall slower than loan rates.

CFHLHFC sector dynamics — Can Fin Homes and peers face the steepest NIM pressure. Watch for pricing power tests in Q2 disbursements and any announcements of cost restructuring or consolidation talks.
The deposit-cost squeeze is real and spreading. Headline profit growth from PNB, PSB, IDBI, and Can Fin Homes masks a sector-wide margin compression that will become unavoidable as provision tailwinds fade. The next 2–3 quarters will test operational agility: can banks offset margin pressure with volume growth, cost discipline, and transaction income? The data suggests this will be hard. For investors, the inflection from a provision-driven profit cycle to an operating-performance cycle is the key inflection point to monitor. Until then, take headline profit growth with a grain of salt.
This follow-up to the July 13 "Cheap Money Is Gone" report confirms that the margin story is not a large-cap anomaly—it is a sector-wide structural headwind. The depth of the deposit-cost squeeze now extends from HDFCBANK and Kotak down through mid-cap PSU banks and into housing finance. That's the pattern this week's results confirm.
