Share prices of India's largest private bank, ICICI Bank, tanked nearly 10 percent on Indian equities markets Friday on sustained bear hammering based on unconfirmed rumours of it being hit by the global financial turmoil before recovering somewhat by close. “The rumours are baseless because ICICI Bank has enough depth and solvency to withstand even a complete write-off of all its doubtful exposure either in India or abroad,” said Jagannadham Thunuguntla, head of the capital market arm of India’s fourth largest share brokerage firm, the Delhi-based SMC Group.
