It can probably be considered that the cessation of Russian imports caused a supply shock. Finnish pulp production was built partly on Russian wood, i.e., cheap pulpwood. At the current cost level, production is not profitable; that is the fundamental problem. Therefore, either pulp mills must be closed or more wood must be sourced from somewhere for the fiber market. Or then we should be able to process products that can withstand a higher price for raw wood.
The market price of wood is always right, whether it is cheap or expensive. But it is not worth making pulp at a loss.
