FED does not put money at risk since unlike every other institution they create $ out of thin air
Creating $ out of thin air also creates inflation within the financial system, benefitting debtor institutions and hurting creditors. It also sets a precedent that the Fed will simply push the magic money button whenever something goes wrong, which affects market behavior.
The Fed pays a price every time it takes any action - you just have to think harder about what that price is.
