What financial ratios matter most for analysing Indian banks?

The four most important ratios for Indian banks are Net Interest Margin (NIM), Return on Equity (ROE), Gross NPA ratio, and CASA ratio. NIM above 4% indicates strong pricing power; ROE above 15% signals efficient capital use; Gross NPA below 2% shows credit quality; and CASA above 40% means low-cost funding. Use the BBS Stock Scorecard to benchmark any bank against these thresholds.

How is a private bank different from a PSU bank for investors?

Private banks typically have higher ROE (15-20%) vs PSU banks (8-12%), better asset quality, and stronger fee income. PSU banks trade at lower Price-to-Book multiples (0.5-1x) vs private banks (2-4x). The trade-off is that PSU banks have government backing and broader rural reach. BBS analysis uses PB ratio and ROE together to judge which is more attractive at a given price.

What causes NPA cycles in Indian banking?

NPA (Non-Performing Asset) cycles are typically triggered by over-lending to a particular sector during boom times — infrastructure, real estate, or telecom — followed by project delays or demand collapse. Banks that concentrated corporate loans without adequate collateral coverage face the most severe NPA cycles. The BBS Red Flag Detector identifies OCF/PAT divergence and rising interest coverage stress as early warning signals before NPAs spike.

SBI vs HDFC Bank Comparison 2026 | NIM ROE Balance Sheet

State Bank of India has ₹61 lakh crore in assets — nearly double HDFC Bank. But HDFC Bank's ROE is consistently double SBI's. One is scale; the other is efficiency. A complete balance sheet comparison reveals why both can coexist in a well-constructed portfolio — and what each is really pricing.

India's banking sector is dominated by two giants at opposite ends of the ownership spectrum: State Bank of India (SBI), the largest public sector bank, and HDFC Bank, the largest private sector bank. Every serious investor in Indian equities must understand both — and the comparison reveals as much about how Indian banking works as it does about the two specific companies.

Scale vs Efficiency: The Core Contrast

SBI's total assets of ₹61 lakh crore dwarf HDFC Bank's ₹35 lakh crore. Yet SBI's Return on Equity (ROE) of ~15-17% lags HDFC Bank's ~16-18%. The gap is closing — SBI has dramatically improved its asset quality and operational efficiency over the last five years — but the structural differences remain. SBI carries priority sector lending obligations (40% of loans must go to agriculture and small businesses), government salary accounts, and the weight of historical NPAs that are still working through the system.

Asset Quality: A Five-Year Transformation at SBI

SBI's GNPA ratio peaked at 10.9% in FY18 — a crisis level that reflected years of infrastructure lending gone wrong. By FY25, GNPA had improved to ~2.2% — a remarkable turnaround driven by resolution under IBC, write-offs, and improved underwriting standards. HDFC Bank's GNPA has remained stable at ~1.2-1.4% throughout, reflecting a culture of conservative credit that is deeply embedded in the institution.

SBI total assets: ₹61 lakh crore | HDFC Bank: ₹35 lakh crore
SBI GNPA FY25: ~2.2% | HDFC Bank: ~1.24%
SBI NIM: ~3.2% | HDFC Bank NIM: ~3.4% (post-merger)
SBI ROE: ~15-17% | HDFC Bank ROE: ~16-18%
SBI CASA ratio: ~43% | HDFC Bank: ~44%

🔍 BBS Insight

SBI and HDFC Bank are not substitutes — they suit different portfolio objectives. SBI is a deep-value, high-dividend yield play on India's economic growth with PSU risk. HDFC Bank is a quality-compounding play with premium valuation. The classic portfolio approach: own both. SBI at 1.0-1.2x book provides value; HDFC Bank at 2.5-3.0x book provides quality. The analytical mistake is to dismiss SBI because it is a PSU or to dismiss HDFC Bank because it is expensive. Read both balance sheets before deciding.
