More than €113bn worth of Government bonds were outstanding in April, according to the Central Bank, with 11.5% of them due to mature in less than three years.
A further 41% of outstanding bonds will mature in five to ten years, while almost a quarter have a maturity of more than 15 years.
The majority of Irish Government bonds (52.5%) are currently held by non-resident investors, according to the figures.
Almost 30% of these - or €17.6bn worth of bonds – will mature from 2023 onwards.
Of the bonds held by resident investors, the vast majority of those are held by credit institutions and the Central Bank itself.
A quarter of these resident holdings are due to mature in the next five years.
