"That's a call we would be taking in November. . .whether to go for it at all, and if we do decide to go in, then the extent of the amount," managing director for International Banking, Hemant Contractor, told reporters.
He said it would be a 'benchmark issue', which normally means the minimum issue size would be at least $500 million.
The bank had earlier announced that it would double its medium term note borrowings to shore up the tier-II capital to $10 billion this fiscal.
Chairman Pratip Chaudhuri, in September, had hinted at raising over $1 billion in November but sounded sceptical following the downgrade by Moody's.
On October 4, Moody's Investors Service had cut rating on SBI's financial strength to D+ from C- and pointed to issues with asset quality and lower capital adequacy.
The bank's core tier-I capital stood a low 7.6 per cent as of the June quarter.
Ratings downgrades usually increases the costs of borrowings for financial institutions.
Contractor said the rates have gone up in international markets due to lower liquidity conditions, but did not answer when asked if the downgrade
