HDFC Bank reported a striking divergence in Q2FY27: deposits surged 18.8% year-on-year to ₹33.28 lakh crore, while advances grew 16.3% to ₹32.20 lakh crore. This 2.5 percentage point gap isn't accidental—it's a deliberate strategic choice. The bank mobilized a staggering $11.5 billion (₹1.10 lakh crore) in FCNR(B) deposits between June and August 2026 under the RBI's concessional swap facility. This alone contributed roughly 35% of the total deposit growth for the quarter.
But here's the rub: the quality of this deposit growth has shifted. Time deposits exploded 22.8% YoY, while low-cost CASA deposits crawled at just 10.8%. This mix matters because FCNR(B) deposits cost around 6%, and while the RBI absorbs 280-300 basis points of hedging costs, they're still pricier than CASA. The net interest margin has already compressed to 3.26% in Q1FY27—an all-time low—and this funding mix suggests more pressure ahead.
Digging into HDFC Bank's loan book, the growth engines are firing on multiple cylinders. MSME/SME loans led the pack at approximately 20% YoY growth, with the bank holding the #1 or #2 position in 25 out of 28 states. Mortgages and home loans showed consistent demand, supported by an expansion from 6,800 to 7,800-8,000 locations. Auto loans and business banking also posted strong gains, with business banking specifically growing 22.3% YoY. Transcript +4
Compare this to the PSU peers. Punjab National Bank saw MSME growth at 19.8% YoY, retail at 17.5%, and agriculture at 16.4%. Bank of Baroda took a different path—gold loans exploded 84.9% in retail and 38.4% in agriculture, while MSME grew 20.3%. The common thread? MSME is the universal growth driver across all three banks, but the strategies differ. HDFC Bank leans on its distribution network and cross-selling (23% of home loan customers now have active credit cards), while PSU banks are leveraging digital cash flow-based lending and aggressive gold loan products.

While HDFC Bank's stock struggled, PSU banks partied. Punjab National Bank jumped 4%, Bank of Baroda rose 3%, and AU Small Finance Bank climbed 3.88% following their Q2 updates. The reasons are straightforward: value re-rating driven by genuine operational improvement.
PNB's global business grew 11.95% YoY to ₹31.20 lakh crore, with advances up 14.8% and the credit-deposit ratio improving to 75.56%. Bank of Baroda's global business surged 17.45% to ₹32.64 lakh crore, with advances growing 18.27%. AU Small Finance Bank benefited from RBI's in-principle approval for its transition to a universal bank, with deposits jumping 28.6% YoY.
The valuation math tells the story. PNB trades at a PE of 5.71x and PB of 0.87x. Bank of Baroda is even cheaper at 6.52x PE and 0.71x PB [stock_agent]. These are deep value levels. HDFC Bank, despite its superior fundamentals, trades at 13.44x PE and 1.84x PB—and has delivered a painful -26.98% return over the past year [stock_agent]. The market is rotating to undervalued PSU banks with improving fundamentals, while discounting HDFC Bank's premium valuation amid NIM compression and leadership uncertainty.
HDFC Bank's asset quality remains the gold standard—gross NPAs at 1.15%, the lowest in the industry on this book size, with a 125 basis point provisioning buffer. The bank's "responsible growth" philosophy, calibrated to nominal GDP growth, has kept credit costs low while maintaining strong expansion. Transcript +4
AU Small Finance Bank takes a different tack. Its gross NPA ratio stands at 2.10%, with net NPAs at 0.76%. The key difference: 90% of AU's business is secured, providing better loss protection, and it uses extensive AI and analytics for risk assessment. The bank also leverages government guarantee schemes aggressively—96% of its MFI book is covered under CGFMU. While HDFC Bank relies on scale and distribution, AU Small Finance Bank bets on technology and secured lending to manage risk. Investor Presentation +4
This is where HDFC Bank's strategy pays dividends. With deposits growing faster than advances, the bank enjoys a funding surplus that peers can only envy. PNB's advances are growing faster than deposits (14.8% vs 9.9%), pushing its CD ratio to 75.56%. Bank of Baroda faces a similar gap—advances at 18.27% growth vs deposits at 16.75%.
HDFC Bank's liquidity metrics tell the story: LCR at 115%, NSFR at 119%, both comfortably above regulatory minimums. The bank has successfully normalized its post-merger CD ratio from around 110% to approximately 96.7% in Q2FY27. This funding surplus provides strategic flexibility—the bank can accelerate loan growth when opportunities arise without scrambling for deposits or paying up for wholesale funding.

Despite the deposit-led growth pressure on margins, HDFC Bank maintains a significant ROA advantage. In Q1FY27, HDFC Bank's ROA stood at 1.85%, compared to PNB's 1.04% and Bank of Baroda's normalized 1.10%. That's an 81-75 basis point lead that persists despite margin headwinds.

The capital position is equally impressive. HDFC Bank's total capital adequacy ratio sits at 19.6%, with CET1 at 17.4%—the strongest among peers. PNB is at 18.13% total CAR with 14.52% CET1, while Bank of Baroda stands at 16.30% total CAR. This capital strength, combined with superior asset quality and operational efficiency, explains why HDFC Bank commands a valuation premium even as the stock struggles. Investor Presentation +3
HDFC Bank's deposit mobilization priority isn't just strategic—it's regulatory. The RBI's LCR requirement is 100%, and HDFC Bank maintains a healthy 115% buffer. The NSFR requirement is also 100%, and the bank sits at 119%. New RBI guidelines effective April 1, 2026, introduced additional run-off rates for digital deposits and adjusted haircuts on government securities—changes estimated to improve the banking system's LCR by 6 percentage points. Investor Presentation
The post-merger CD ratio normalization has been a key focus. From roughly 110% after the HDFC Ltd merger, the bank has brought it down to around 96.7% in Q2FY27, targeting 85-90% by FY27. This required deliberate slowing of loan growth on larger ticket sizes with stubbornly low pricing. The strategy has worked: the loan-deposit ratio is no longer a binding constraint, and the bank has gained 30-50 basis points of deposit market share annually over the past five years. Transcript +3
The divergence in market reactions—PSU banks rallying while HDFC Bank languishes—reflects different investment theses. PSU banks offer value re-rating as operational improvements translate to earnings growth. HDFC Bank offers quality and compounding, but the market wants to see NIM stabilization and leadership clarity before rewarding the stock.
For HDFC Bank, the near-term challenge is clear: improve the deposit mix by growing CASA faster than time deposits, and demonstrate NIM recovery as high-cost borrowings mature. The bank has ₹40,000-50,000 crore of high-cost borrowings maturing over the next two years, which should support funding cost improvement. Once the CD ratio target is achieved and liquidity normalizes, expect loan growth to accelerate.
The broader banking sector remains healthy. Systemic credit growth is robust at 18.8%, driven by retail demand, MSME utilization, and corporate borrowings. Asset quality across the system is stable, and PSU banks have transformed their NPA profiles to match private sector peers. In this environment, both HDFC Bank's quality-first approach and PSU banks' value-driven growth have merit—but the market, for now, is voting with its wallet for the latter.
