Rating agency Standard & Poor's on Monday raised Ireland's sovereign outlook to stable from negative, citing expectations for lower debt servicing costs and refinancing risk.
The agency currently rates Ireland BBB-plus.
The move "reflects our expectation that the exchange of promissory notes for longer-term government bonds significantly reduces the Irish government's debt-servicing costs and refinancing risk, and supports medium-term fiscal consolidation," S&P said in a statement.
"By improving the government's debt-maturity profile, the transaction also increases the prospects of Ireland leaving the EU/IMF bailout program as planned at the end of 2013."
Moody's Investors Service rates the country Ba1 with a negative outlook, below investment grade. Fitch rates Ireland BBB-plus with a stable outlook.
