The National Treasury Management Agency is to issue a 30-year bond, with an expected range of €1.5bn-€2bn, in the coming days.

The auction will be the first time the country has issued a standard bond with such a long maturity.

The NTMA said it had mandated a number firms – namely Barclays, Citi, Credit Agricole CIB, Danske Bank, Davy and Royal Bank of Scotland – as joint-lead managers for the transaction.

It said the sale is expected to be launched and priced “in the near future subject to market conditions”, with the bond due to mature on 18 February 2045.
