Earlier in December, the bank had announced raising Rs 12,000 crore through issue of debt instruments in tranches.

SBI, on previous two occasions, had informed the exchanges that it raised Rs 4,000 crore and Rs 3,000 crore in two tranches through issue of debt instruments as part of the Rs 12,000 crore fund raising programme.

The lender in a filing to the BSE today said, "The Committee of Directors for Capital Raising met on March 9, 2016 to review the implementation of its resolution dated December 21, 2015 with regard to issue of debt instruments".

It authorised the Bank to "consider raising the residual amount (out of the overall approval obtained for raising the debt capital amount of Rs 12000 crores), either by way of issue of AT-I/Tier-ll instrument or any other debt instrument at appropriate time(s), by way of private placement, in such number of tranches, as may be considered appropriate," the filing said.

Earlier on February 19, the bank informed BSE that it raised Rs 3,000 crore from Basel-III compliant bonds to fund business growth.

According to a Fitch Ratings report, Indian banks need USD 140 billion capital to ensure full compliance with the Basel III norms by 2018-19.
