The Central Bank has confirmed it has taken back handling of certain tasks and functions it had delegated to the Irish Stock Exchange in relation to market abuse.

The market abuse delegation arrangement with the ISE had been in place since 2005. The monitoring and investigation functions, which had been carried out by the exchange, will now be conducted by the Markets Supervision Directorate of the Central Bank.

The bank said it has also reviewed its market abuse rules and the amended rules can be viewed on its website.
