3,897 records under review

The bank said its threat intelligence provider, the Defence Cyber Agency and CERT-In raised the alert on October 16, 2026. A preliminary review covered approximately 375,000 records found online and identified 3,897 records containing personally identifiable information.

State Bank of India said the exposed material included names, mobile numbers, dates of birth, email addresses, residential addresses and identifiers connected with loan and lead records. It has appointed an independent CERT-In-empanelled cybersecurity agency to conduct a forensic assessment and determine the source of the exposure, EquityBulls reported on October 21, 2026.

Profit backdrop remains important

The latest reported operating backdrop came from the first quarter of fiscal 2027. SBI posted net profit of INR 211.21 billion, operating profit growth of 9.77 percent and a domestic net interest margin of 3.00 percent, according to Quartrly on October 6, 2026. The same review said management guided fiscal 2027 credit growth of 14.00 to 15.00 percent.

Price sits above the yearly low

The October 21, 2026 NSE price of INR 963.00 stood 6.89 percent above the 52-week low of INR 900.95 and 22.00 percent below the 52-week high of INR 1,234.70. Trading volume reached 10,249,390 shares.

Valuation and investor dates

State Bank of India's market capitalization was INR 8.9 trillion on October 21, 2026, while its price-to-earnings ratio was 10.31. The cybersecurity disclosure adds an operational risk point to a stock otherwise being assessed against earnings, credit growth and margin trends.

The bank's next financial update remains the key scheduled corporate marker after the first-quarter figures. For investors, the contrast is clear: the current issue concerns data governance, while the valuation still rests on the bank's earnings scale and balance-sheet growth.

Stock reaction stays measurable

State Bank of India stock fell 1.10 percent on the NSE reference close to INR 963.00 on October 21, 2026. The move leaves the stock above its yearly low but below its yearly high, keeping the market reaction measurable rather than defining the longer-term valuation picture.
