This was ultimately just a transfer of wealth between two parties. There wasn't much of a loss for society as a whole (besides maybe to Aas's creditors and the clearing house but they can handle this risk)...
The fund that got depleted has to be topped off again, with money from the other participants in the market. Fortum, for instance, will have to pay ~23M euro, and is largely owned by the Finnish state. Same goes for lots of the other players.
