I can't find the implied default credit default swap rates for 1 year and 2 year NTMA Irish government bonds online.
Suffice the say the risk inside 1-2 years is much lower. A lot of people expect the IMF/EC bail out fund to be enacted as a first step. The market CDS rates now imply a higher but not certain expectation of a default in the medium to long term. The short term default risk is on a much lower CDS probability expectation thanks to the bail out fund.
If I had to guess, I would say an Irish default will happen but not for at least 3 years, after the expiration of the ECB/IMF bail out.
Most fund managers, according to a recent Bloomberg survey, expect a Greek default by 2014. Perhaps a regional debt re-structuring will take place then.
All pure speculation. It could happen sooner. It may never happen.
