S&P Global Ratings on Thursday said it has raised long-term issuer credit rating on Reliance Industries to ‘A-‘ from ‘BBB+’. The rating firm also raised its long-term issue ratings on the senior unsecured debt the company issued to ‘A-‘ from ‘BBB+’. “The stable rating outlook reflects our view that the conglomerate will maintain its leading market position in its key businesses, and its earnings will be sufficient to cover capital spending over the next 12-24 months,” the rating firm said.
