Some Indian companies could see the quality of their debt decline as higher global borrowing costs and a sharply weaker rupee take their toll, Moody's Investors Service said.
Companies such as Indian Oil, Tata Steel and Tata Power will remain highly leveraged over the next 12 months because of weak industry dynamics and resulting constraints on cash flows, it said.
"We believe they will be able to refinance their maturing debt, but possibly at higher credit spreads than on existing debt," the agency said.
But while the rupee has slumped as much as 20 percent this year, it said rated Indian non-financial companies should be able to meet their $32.8 billion in debt coming due through March 2014, more than half of which is denominated in foreign currency, as they will continue to have access to offshore and onshore funding sources.
State-run companies Oil and Natural Gas, Bharat Petroleum and Indian Oil, and private sector energy conglomerate Reliance Industries, together account for 60 per cent of the total rated corporate debt maturing through next March, it said.
The agency said that as domestic interest rates are also rising most companies will face higher borrowing costs after refinancing of existing debt.
