PSU Banks FY26 Re-rating: SBI, BoB, Canara, PNB & Union Bank

India's public-sector banks have had a remarkable rehabilitation story — from the NPA crisis years of 2016–2019 to record profits in FY26. Yet most PSU bank stocks remain stuck below their book values and well off 52-week highs. The disconnect between fundamentals and valuations makes this one of the most interesting setups in Indian equities right now.

We pulled live data from NSE/BSE audited filings via DocStoX data for SBI, Bank of Baroda, Canara Bank, PNB, and Union Bank of India — every figure below is sourced directly from quarterly filings, not modelled estimates.

FY26 Profit Scorecard: The Numbers Are Real

The aggregate FY26 net profit of India's five largest PSU banks crossed ₹1.62 lakh crore — a figure that would have seemed implausible during the twin-balance-sheet crisis era. Here's the breakdown (sum of four quarterly PATs, FY26):

• State Bank of India (SBIN): FY26 PAT ₹86,666 crore (Q1: ₹22,121 Cr + Q2: ₹21,861 Cr + Q3: ₹22,176 Cr + Q4: ₹20,508 Cr)
• Bank of Baroda (BANKBARODA): FY26 PAT ₹20,071 crore (Q1: ₹3,517 Cr + Q2: ₹5,181 Cr + Q3: ₹5,501 Cr + Q4: ₹5,872 Cr)
• Union Bank of India (UNIONBANK): FY26 PAT ₹19,431 crore (Q1: ₹4,428 Cr + Q2: ₹4,426 Cr + Q3: ₹5,073 Cr + Q4: ₹5,504 Cr)
• Punjab National Bank (PNB): FY26 PAT ₹18,467 crore (Q1: ₹2,167 Cr + Q2: ₹5,121 Cr + Q3: ₹5,577 Cr + Q4: ₹5,602 Cr)
• Canara Bank (CANBK): FY26 PAT ₹17,878 crore (Q1: ₹3,233 Cr + Q2: ₹4,896 Cr + Q3: ₹5,174 Cr + Q4: ₹4,575 Cr)

SBI alone earned more in FY26 than the entire PSU banking system did in FY20. That is the scale of the turnaround.

Valuations: Trading Below Book Despite Record Earnings

Here is the paradox: all these profits, yet most PSU banks trade at steep discounts to book value and single-digit P/E multiples (data as of July 2026, DocStoX data from NSE filings):

• SBI: ₹1,022 | Market cap ₹9.43 lakh Cr | ROE 15.4% | Implied P/E ~10.9x | 52w high ₹1,234.7
• Bank of Baroda: ₹244.6 | Market cap ₹1.27 lakh Cr | ROE 12.7% | P/B 0.77x | Div yield 3.43% | 52w high ₹325.5
• Union Bank of India: ₹157.3 | Market cap ₹1.20 lakh Cr | ROE 15.7% | P/B 0.92x | Div yield 3.10% | 52w high ₹205.5
• Canara Bank: ₹124.8 | Market cap ₹1.13 lakh Cr | ROE 16.1% | P/B ~0.96x | Div yield 3.36% | 52w high ₹162.9
• PNB: ₹103.4 | Market cap ₹1.19 lakh Cr | ROE 13.0% | P/B 0.80x | Div yield ~2.5% | 52w high ₹135.2

Bank of Baroda at 0.77x book and a 3.43% dividend yield is arguably the most undervalued by traditional bank metrics. Canara Bank has the highest ROE in the group at 16.1%, yet trades closest to — but still below — book. Union Bank's profit CAGR of 46.9% over five years makes its sub-1x P/B look anomalous.

Why Are PSU Banks Still Cheap?

The market's scepticism has three legs:

1. Asset quality overhang: Contingent liabilities remain enormous (SBI's stands at ₹43.5 lakh crore). While GNPA ratios have fallen sharply across the sector, the market prices in a tail risk of a fresh NPA cycle, especially given the agri-loan moratorium history and new MSME stress signals.
2. Government ownership discount: PSU banks are expected to lend to priority sectors and fund government programmes — often at the cost of optimal capital allocation. That implicit cost is real and hard to price.
3. Net Interest Margin (NIM) pressure: As the RBI rate cycle turns down, NIMs are expected to compress. The PSU bank rally of FY22–FY24 was partly a NIM expansion story — that tailwind is now reversing.

The Bull Case: What the Bears Are Missing

There is a credible counter-argument. PSU banks have cleaned up their books more thoroughly than most investors give them credit for. The provisioning cycle is behind them; credit costs have normalised. Net NPAs are at multi-year lows across the sector.

SBI's ROE at 15.4% is now competitive with mid-tier private banks. Canara Bank's ROE at 16.1% is higher than HDFC Bank's — a remarkable inversion from three years ago. And the dividend yields (Bank of Baroda at 3.43%, Canara at 3.36%) are higher than most fixed-income alternatives at current yields, providing a floor on valuations.

PNB's five-year profit CAGR of 48.2% shows the recovery is genuine, not a one-year blip. Union Bank's trajectory — four consecutive quarters of PAT growth culminating in ₹5,504 crore in Q4 FY26 — points to a structurally improved franchise.

What to Watch

The re-rating will come — or not — based on three data points investors should track every quarter:

1. GNPA and NNPA ratios: Any fresh slippage in agri, MSME, or infrastructure loans will reset sentiment quickly. The signal to watch is SBI's slippage ratio (it tends to lead the sector).
2. NIM trajectory: The RBI's rate cuts will compress yields on the asset side faster than PSU banks can reprice deposits. A NIM decline of more than 20bps quarter-on-quarter is a warning.
3. Credit growth: PSU banks have been gaining share in retail and housing loans. Sustaining 12–15% credit growth while keeping NIMs stable is the path to book-value accretion.

The DocStoX Take

The data makes a compelling case that PSU banks are priced for a pessimistic scenario that is no longer the base case. Combined FY26 profits of ₹1.62 lakh crore, ROEs in the 13–16% range, and P/B multiples below 1x for most of the group — that combination has historically resolved in favour of the bulls over a 2–3 year horizon in Indian banking.

The entry risk is macro (a fresh credit cycle turning), not fundamental (these banks are not going back to the NPA era). SBI at ~10.9x FY26 earnings provides the best risk-adjusted entry among the five, given its scale, liability franchise, and dominant market position.
