Reuters reports that ECB bank supervisor Andrea Enria said that a European Deposit Insurance Scheme, long advocated by the ECB, is unlikely to be agreed on in the coming years.

"A fully fledged EDIS should remain the goal but will not be there in the coming months and years," Enria told.

The absence of the euro zone-wide insurance scheme is seen as a key impediment in the integration of the bank sector, which is now fragmented along national lines, keeping profitability and efficiency low.
