Lol. The federal reserve isn't company. It is a quasi government arm that is privately owned and partially privately run where all profits go back to the Treasury.
But if you want to include them, ok.
What does the federal reserve need to continue operating? The government...they need the federal reserve act of 1913, aka, a law, to continue operating. Without it they shutdown. Without the government, nobody would listen or use them.
I rest my case.
