Indian shares hit a record high for a fifth straight session yesterday as state-run lenders such as State Bank of India continued their recent rally after the central bank extended the deadline for implementing Basel III capital-raising rules.

Heavy buying by overseas investors also continued to help underpin gains, sending the NSE index to its first weekly gain in three.

Overseas funds’ net purchases of shares have reached nearly $3bn so far this month, according to regulatory data.

A combination of foreign flows, hopes for a recovery in the domestic economy, and bets that the main opposition Bharatiya Janata Party, perceived as more business-friendly, will come to power have driven a 6.8% gain in the NSE index in 2014 so far.

Investors say the central bank’s policy review on April 1,where it is widely expected to keeps rates unchanged, and the coming general elections would act as the next key catalysts for markets.

“The outlook remains bullish. The rally would extend itself till the elections are over. RBI may keep rates unchanged,” said G Chokkalingam, founder of research and fund advisory company Equinomics.

The NSE index rose as much as 0.9% to an all-time high of 6,702.60, while the benchmark BSE index gained 0.67% to a lifetime high of 22,363.97.

The BSE index closed 0.57% higher for the day and 2.7% for the week, while the NSE index ended up 0.82% yesterday while posting a weekly gain of 3.1%.

State-run banks extended recent gains after the Reserve Bank of India on Thursday extended the deadline for banks to implement Basel III capital rules by a year to March 31, 2019, due to concerns from the industry on potential stress to asset quality.

State Bank of India gained 3.5%, Bank of Baroda rose 5.1% and Punjab National Bank advanced 6.4%.

Banks have surged this month with the NSE bank sub-index up 18.5% on hopes of a recovery in the domestic economy, central bank’s potentially easing monetary policy and broker upgrades.

Software exporters gained despite the rupee’s rise to its eight-month high after global rival Accenture on Thursday raised its full-year profit forecast and the lower end of its revenue forecast.

That helped bring some relief after Tata Consultancy Services and Infosys warned about their quarterly revenue growth in recent weeks.

HCL Technologies rose 1.2%, Infosys rose 1% and Tata Consultancy Services gained 0.4%.

Hindalco Industries gained 4.4% on expectations global aluminium premiums would be supported after the London Metal Exchange suffered a legal setback in its plan to free up metal more quickly from its warehouses.
