Last year, non-financial corporates raised USD 15 billion in debt from overseas market.
"Domestic corporate have already raised around USD 18 billion through offshore bonds in transactions numbering 30-35 so far during the current year (CY2014) and this is likely to top USD 20 billion next year.
"Moreover, there are at least one or two such transactions in the pipeline this month," said RBS head for debt capital markets (India & Southeast Asia) Manmohan Singh.
Overseas debt raising will continue as corporate will continue to pare their domestic debt, he added.
On India's credit outlook, Singh said "If the momentum in the economy continues and oil prices continue to fall, then there could be a rating upgrade. As we speak today on a relative value basis, investors think that we are expensive.
