The National Treasury Management Agency has released its plan to re-enter the international bond markets.

NTMA Chief Executive John Corrigan said he aims to phase Ireland's re-entry to the international bond markets over the coming 18 months.

The agency intends holding at least three auctions of short-term treasury bills between now and the end of the year.

These auctions will be similar to the one successfully concluded two weeks ago.

It is going to sell bonds that target pension funds and repay interest and capital over the lifetime of the loan, instead of repaying the capital at the end of loan.

It is also to sell inflation-linked bonds in an effort to woo investors.

Mr Corrigan said 80% of investors who bought the €500m short-term treasury bill issued by the organisation on 5 July were based abroad.
