If I saw those balances above all moving at once I would expect the price to become too cheap. It would then spike down and back up again, sharp like shutting off a tap suddenly. After that the market tries to right itself in one direction but a more progressive way.
They could drip those balances in over 6 months, I really expect that but cant be sure with a liquidator exactly. I know with Lehman brothers, that company will be 'operating' running down its various assets for decades probably.
Mentioned this before, but there's unlikely to be any more movements until there is a ruling on CR (civil rehabilitation). The trustee has made creditors whole with respect to their JPY claims - he has no reason to take further action.
