AFAIK, the underlying assets in investment accouns are owned by their account holders, the broker just manages them. If the broker becames insolvent, these assets are not part of insolvency proceeding. For regular bank account, there are no other underlying assets, it is just the sum bank owes to the account holder. If the bank becames insolvent, outside of insurance limits, these are just claims against the bank.
