Irish households withdrew €541 million in deposits last month, according to new private sector credit figures from the Central Bank.
The preference for overnight and short-term deposit accounts continues, also owing to the low interest rate environment.
Banks now hold €3.6 billion more household deposits than loans.
It means households were net funders of the banking system for the eight consecutive month, a situation which has not happened since before the turn of the century.

Households repaid € 1.9 billion more than was issued in the form of new loans.
The amount of outstanding non-housing related loans also fell by €48 million for the month, down 3.9% in the year.
