The proportion of Irish government debt owed to people and institutions resident outside the state has risen significantly over the past 12 months.
Non-residents held 58.9% of Irish government bonds, €73 billion at face value, up from 52.4% a year earlier.
The latest Central Bank figures, which cover the period up to the end of May 2015, show the nominal value of outstanding Irish government bonds was €124 billion, an increase of €789m compared to the previous month.
A statement by the Central Bank alongside the figures said this reflects the fact that a large proportion of government bonds which have been issued over the past year have been bought by non-residents.
