The Dutch central bank has added BNG to its list of banks considered too big to be allowed to fail, taking the total to five.

BNG (Bank Nederlandse Gemeente) is 50% owned by the Dutch state and 50% by local councils and provinces and focuses on financing for public sector bodies.

BNG has been included because it ‘has a relatively large balance sheet and is interconnected with other domestic and foreign financial institutions,’ the central bank said in a statement.

The other four banks classified as systematically important are ING Bank, Rabobank, ABN AMRO and SNS. The Dutch state owns SNS and has a majority stake in ABN Amro.

Inclusion on the list means the five systemically important banks must maintain an additional capital buffer to be able to better absorb unexpected losses. The buffers will be phased in between 2016 and 2019.
