Why IOB Share Price is Falling

Indian equity benchmarks Sensex and Nifty slipped sharply from the day's highs on 17 December 2025 amid heightened volatility and were on track to extend losses for a third straight session.

Market sentiment remained mixed to weak, as broad-based sectoral pressure outweighed pockets of selective buying.

Against this backdrop, the Nifty Bank index also came under selling pressure, reversing early gains of about 50 points to trade over 120 points lower and nearly 200 points below the day's high.

Amid the broader weakness, Indian Overseas Bank (IOB) grabbed market attention, with its share price falling over 6% during the session. Here's what's driving the decline.

# Offer for sale

The government's proposal to sell up to 3% of the company's shares through an offer for sale (OFS) sparked the selling pressure.

The filing for OFS states that under the "Base offer," the promoter (government) plans to sell up to 385.1 million (m) shares, approximately 2% of the bank's total issued and paid-up equity share capital on 17 December 2025, "T Day," for non-retail Investors.

Up to 150,000 shares may be set aside for qualified workers as part of the OFS, subject to approval. Employees may apply for shares worth up to Rs 0.5 m, according to the bank.

This is in line with the Securities Contract (Regulation) Rules issued by the Securities and Exchange Board of India, which mandate that all listed companies, including those in the public sector, must have a minimum public shareholding of 25%.

August 2026 has been designated as the compliance deadline. The promoter currently owns 94.61% of the holding in IOB.
