You’ve been chasing low‑cost deposits while ignoring the real catalyst: credit growth.
All other risk gauges—non‑performing assets, loan‑book quality, provisioning—have steadied or improved across India’s major banks. Yet the market’s focus remains fixated on the headline‑grabbing cost of deposits, a narrative that diverts attention from the engine that truly drives earnings: the pace and source of credit expansion. In this deep‑dive we unpack why credit growth is the single most decisive metric for banking stocks, how segment‑level dynamics are reshaping the competitive landscape, and what you should do with this insight today.
Why Bank Credit Growth Is the Sole Indicator Investors Should Track
Revenue for banks is a direct function of the interest earned on advancing loans. When credit expands, the top line rises, and margins improve provided funding costs remain stable. Conversely, a stagnant loan book forces banks to lean on fee income, which is less predictable and often lower‑margin. The current environment presents a rare alignment: NPA ratios are at multi‑year lows, and asset quality is solid, leaving credit growth as the primary lever to lift earnings.
Technical definition: Credit growth measures the year‑over‑year change in a bank’s total loan portfolio. A double‑digit expansion in a sector with thin margins can add billions to net interest income (NII), dwarfing the incremental impact of a 10‑basis‑point shift in deposit rates.
Segment‑Level Credit Expansion: Retail vs. Corporate
Retail loans—home mortgages, auto finance, and consumer credit—are surging on two fronts: rising disposable incomes and aggressive digital onboarding. According to internal data, retail credit grew 16% YoY last quarter, outpacing corporate credit’s 9% increase. This shift matters because retail assets typically carry lower risk‑weighted assets (RWA) and higher spreads, boosting the capital efficiency of banks.
Corporate lending, while still essential, faces tighter underwriting as firms brace for higher input costs. The net effect is a tilt toward higher‑margin, lower‑risk retail exposure, a trend that should reward banks with robust retail footprints such as HDFC Bank and Axis Bank.
How Major Lenders Like HDFC and SBI Are Positioning Their Loan Books
HDFC Bank has doubled down on its retail strategy, launching a suite of digital mortgage products that cut acquisition costs by 30%. Its credit‑growth trajectory is now anchored at 18% YoY, well above the industry average. SBI, the behemoth of public‑sector banking, is leveraging its vast branch network to cross‑sell retail products, achieving a 13% retail‑credit growth while keeping corporate exposure stable.
Both banks report NPA ratios of under 1.2%, a level that historically precedes a multi‑year earnings acceleration phase. Their balance sheets illustrate a classic “growth‑quality” sweet spot: expanding loan books with minimal credit deterioration.
Historical Credit Cycles: Lessons From the 2013‑16 Credit Surge
During the 2013‑16 period, Indian banks witnessed a credit‑growth spurt averaging 14% per annum. Those that capitalized on the wave—primarily private‑sector banks—outperformed peers by 250 basis points in return on equity (ROE). Conversely, banks that remained overly cautious on loan disbursement saw flat earnings and share‑price stagnation.
The key lesson is timing. Investors who entered the market when credit growth turned positive captured the upside, while those who waited for NPA metrics to improve missed the bulk of the rally.
Deposit Cost Pressure: Myth or Market Reality?
Yes, deposit rates have risen modestly as the RBI tightens policy, but the impact on banks’ net interest margins (NIM) is marginal when credit growth remains robust. A 20‑basis‑point rise in deposit cost typically erodes NIM by only 5‑6 basis points if loan yields stay on an upward trajectory. Moreover, banks can mitigate cost pressure through tiered pricing, encouraging high‑balance, low‑cost savings via digital platforms.
In practice, the market’s overemphasis on deposit costs creates a valuation discount for banks that are, in fact, poised for earnings acceleration via loan growth.
Investor Playbook: Bull and Bear Scenarios for Banking Stocks
Bull Case: Credit growth sustains double‑digit rates for the next 12‑18 months, driven by retail demand and digital acquisition efficiencies. NPAs stay below 1.5%, and deposit‑cost pressure remains contained. Under this scenario, banks’ earnings per share (EPS) could climb 12‑15% YoY, pushing price‑to‑earnings (P/E) multiples toward the 20‑22x range.
Bear Case: A slowdown in retail demand, perhaps due to a macro‑wide slowdown or tighter credit underwriting, reduces credit growth to sub‑5% levels. Simultaneously, deposit rates climb sharply, compressing NIMs. EPS growth stalls, and valuations retreat to 12‑14x P/E, mirroring the 2020‑21 correction.
Strategic takeaway: Prioritize banks with the strongest retail‑credit pipelines and proven digital onboarding capabilities. Consider scaling exposure on a phased basis, adding positions as quarterly credit‑growth data confirms the trend.
