The NTMA has announced the sale of a range of Irish Amortising Bonds this morning.
It is the first time it has made such a move and it marks the next step, in what officials say, is the diversification of Ireland's sovereign funding.
The bonds have maturities ranging from 15 to 35 years, and the sale will run from around now until 1pm this afternoon.
It is expected that they will be an attractive investment for pension funds.
The National Treasury Management Agency are expected to announce details of how the sale went at around 2pm.
