The Nifty hits a lifetime high of 6,684.95, while the BSE Sensex marks an all-time high of 22,363.97.
State Bank of India (SBI) gains 2.8 percent, Bank of Baroda 2.7 percent and
Punjab National Bank (PNB) 3.3 percent.
Continued foreign investor buying also underpins shares. Overseas investors bought Indian cash shares worth $364 million and equity derivatives worth the same amount on Thursday despite derivative expiry.
Investors say the Reserve Bank of India's policy review on April 1, where it is widely expected to keeps rates unchanged, and general elections due by May would act as the next key catalysts for markets.
