Bandhan Bank Share Price Jumps 8% Today After 4% Fall in a Month: What Is Fuelling the Surge in the Banking Stock? IHC Promoter Stake Talks, Q2 Business Update and CASA Ratio Explained

Bandhan Bank share price jumped about 8% today, and the headline asks what is fuelling the surge in the banking stock after a 4% fall in a month. The main trigger is a report of promoter stake talks, and the Q2 business update adds context on loans, deposits and funding.

This guide explains the Bandhan Bank share price move, how the promoter structure works, what the Q2 FY27 business update and Q1 FY27 results show, how the stock is valued and where the risks sit.

The 4% monthly fall in the headline could not be verified. I can confirm that the stock closed at Rs 176.00 on 1 October and at Rs 157.50 on 12 October, a fall of about 10.5% in 11 days (my calculation).

Bandhan Bank Share Price Today: Price Levels on 13 October

Level	Price (Rs)	Note
Close on 1 October	176.00	Before the recent fall
Previous close, 12 October	157.50	Base for the jump
Opening price	162	About 2.9% above the close (my calculation)
At 11 am	169.40	Up about 7.5%
Intraday high	171.68	About 9.0% above the close (my calculation)

One data page calls the open of the Bandhan Bank share price an 8.29% gap-up, but Rs 162 is only about 2.9% above Rs 157.50, so I used my own calculation. Volume was heavy, with more than 29 million shares worth about Rs 490 crore traded by late morning.

What Is Fuelling the Bandhan Bank Share Price Rally?

1. A media report that IHC, the Abu Dhabi investment company linked to Sheikh Tahnoon bin Zayed Al Nahyan, is in early talks to buy a stake in Bandhan Financial Services, the bank's promoter.
2. Early investors in the promoter, Singapore's GIC and the IFC, are reported to be considering a full or partial exit.
3. Other possible investors were reportedly sounded out, including First Abu Dhabi Bank, Qatar Investment Authority, Carlyle and EQT.
4. A valuation of about 1 times book value, which WealthMills Securities says can draw institutional interest.
5. A comparison with RBL Bank, where institutional investment turned the stock into a turnaround story.

Bandhan Bank chairman Chandra Shekhar Ghosh declined to comment, saying the bank does not comment on market speculation, and First Abu Dhabi Bank also declined to confirm. So the Bandhan Bank share price is moving on a report, not on an announcement.

Bandhan Bank Promoter Stake: How the Structure Works

Item	Detail
Promoter chain	Bandhan Financial Services is the parent of Bandhan Financial Holdings, which held about 37.5% of the bank at the end of June
Early investors in the promoter	GIC holds 16.7% through Caladium and IFC holds 13.59%, together 30.3%
Stake under discussion	25% to 32% of Bandhan Financial Services, reportedly worth about $500 million to $600 million
Adviser	Jefferies, per the report
RBI condition	Promoter holding in the bank must fall to 26% by 2030

To reach 26% from 37.5%, the promoter must cut its holding by 11.5 percentage points (my calculation). A deal in the parent could give early investors an exit, but for the Bandhan Bank share price it would change who sits behind the promoter and not the number of shares the promoter holds in the bank.

Q2 Business Update: What It Shows for the Bandhan Bank Share Price

Measure (30 Sep 2026, provisional)	Figure	Change
Loans and advances	Rs 1,58,335 crore	Up 13.1% year on year; up 1.8% from June
Total deposits	Rs 1,72,689 crore	Up 9.2% year on year; up 4.7% from June
Retail deposits	Rs 1,25,471 crore	Up 11.9% year on year
CASA deposits	Rs 46,131 crore	Up 4.3% year on year; down 4.8% from June
CASA ratio	26.71%	29.40% in June and 27.97% a year ago
Bulk deposits	Rs 47,218 crore	Up 2.8% year on year; up about 10% from June
Liquidity coverage ratio	About 137.88%	Above the 100% minimum

Loans grew faster than deposits, which puts the credit to deposit ratio at about 91.7% (my calculation). The CASA ratio fell 2.69 percentage points from June as bulk deposits rose, which is the weak point in the Q2 business update for the Bandhan Bank share price because CASA deposits are the lowest cost funds.

Q1 FY27 Results and Asset Quality Behind the Bandhan Bank Share Price

Measure	Q1 FY27	Note
Net profit	Rs 502 crore	Up 35% year on year; one source does not state the unit, and crore is likely
Net interest income	Rs 2,921 crore	Up 5.9%
Net total income	Rs 3,524 crore	Not compared
Gross NPA	3.1%	Improved from the previous quarter
Net NPA	0.9%	Improved from the previous quarter
Capital adequacy	18.2%	At the end of June
Network	1,988 branches; 31.8 million customers	At the end of June

Profit growth of 35% is strong, but net interest income grew only 5.9%, so profit was helped by lower costs or provisions. Gross NPA of 3.1% is still high for a private bank, which is why the Bandhan Bank share price trades near book value.

Bandhan Bank Share Price Performance and Valuation

Measure	Figure	Note
Year to date	Up 17%	As reported on 13 October
One year	Flat	As reported
Three years	Down 30%	As reported
Five years	Down 49%	As reported
Price to book	About 1 time	WealthMills Securities
Market capitalisation	About Rs 27,414 crore	At Rs 169.66, from MarketsMojo
Rating and trend	Mojo grade Sell since 8 October	Below the 20, 50, 100 and 200 day averages; above the 5 day average

Delivery volume on 12 October was 26.96 lakh shares, down 49.32% from the five day average, which suggests that much of the trading in the Bandhan Bank share price is short term. At Rs 171.68 the Bandhan Bank share price was still about 2.5% below the Rs 176.00 close of 1 October (my calculation).

Risks Around the Bandhan Bank Share Price

Unconfirmed deal: The Bandhan Bank share price is moving on a report, and no party has confirmed talks.

Indirect stake: A deal would be in the promoter entity, not the bank, so its effect on the bank is limited.

Funding mix: The CASA ratio fell to 26.71%, which can weigh on the Bandhan Bank share price if bulk deposits keep rising about 10% a quarter.

Asset quality: Gross NPA of 3.1% is higher than most large private banks.

Speculative trading: Falling delivery volume and a Sell grade suggest the rally may not be backed by long term buyers.

Promoter overhang: The promoter must cut its holding to 26% by 2030, which can add supply over time.

What to Watch Next

1. Any exchange disclosure from Bandhan Bank or its promoter on the talks.
2. Whether the Bandhan Bank share price holds above the Rs 157.50 previous close.
3. The Q2 FY27 results and their effect on the Bandhan Bank share price.
4. The trend in the CASA ratio and in bulk deposits.
5. Gross NPA and credit cost in the next results.

Conclusion

Bandhan Bank share price rose to Rs 171.68 on a report of promoter stake talks, while the Q2 business update showed solid growth but a lower CASA ratio. Because the deal is unconfirmed and indirect, check official disclosures and your own risk limit before acting. Consult a SEBI-registered advisor before making any decision.
