Ireland's external debt rose to €1.74 trillion at the end of June, according to new figures from the Central Statistics Office (CSO).
This represents a €63 billion increase compared to the €1.67 billion recorded at the end of March.
The figures include general government, the monetary authority, financial and non-financial corporations and households.
Much of the external debt total is offset by holdings of foreign financial assets by Irish residents, the CSO said.
General government foreign borrowing decreased by over €3 billion to €80 billion in the second quarter, the new data shows.
However, the liabilities of other sectors increased by €17 billion from the end of March and at €657 billion represented 38 per cent of the total debt, a similar share to the previous quarter. CSO attributed the increase to currency fluctuations.
Direct investment liabilities increased by €17 billion to €262 billion in the second quarter.
Liabilities of monetary financial institutions which consist mostly of loans and debt securities, were €672 billion, an increase of over €5 billion from March but down compared to June 2009.
Ireland’s quarterly international investment position (IIP) results show overall stocks of foreign financial assets of €2,500billion – an increase of €108 billion from the end of March.
The corresponding overall stocks of foreign financial liabilities of €2,643 billion were up €126 billion.
Irish residents had an overall net foreign liability of almost €143billion in the three months to the end of June, an increase of €18 billion on the previous quarter’s figure of almost €125 billion.
