"The Fund is steadily being built up and we are about half way there. The SRF is a significant part of the SRB's toolbox as it ensures that the SRB will be able to implement a resolution decision without recourse to the taxpayer," SRB chair Elke Koenig said in a statement.

The SRF is meant to finance the winding down of failing banks. Koenig said last year she expected the SRF to hold nearly 33 billion euros in 2019.
