The Exchequer was forced to refund the Central Bank €6.5 million after funds from it were used to reduce debts owed by Somalia and Sudan to the International Monetary Fund.
The Comptroller and Auditor General's report found that in January 2020 and May 2021, Ireland contributed approximately €8.36 million to reducing the debts of both countries.
Some €6.5 billion came from the Central Bank with the balance from the Exchequer.
But in April 2022, the European Central Bank said this was a breach of the Treaty on the Functioning of the European Union on the prohibition of monetary financing.
So, the Exchequer had to refund the Central Bank with a once-off payment of €6.5 million in December 2022.
