Liffe, the derivatives arm of NYSE Euronext, today set a date for the launch of futures contracts linked to the euro overnight interbank average and said plans for a sterling equivalent are still under review, as calls this week increased for alternatives to the hotly debated Libor benchmark.

Liffe, which outlined plans last month for new money market contracts linked to Eonia and Sonia, its sterling equivalent, today confirmed in a statement it will start offering one-month Eonia futures and three-month swap index Eonia futures from June 16.
