I'm quite niave in the ways and make up of financial instituations. But from what I can tell - many of the US regulatory bodies seems to be private (but not ostensibly for profit) companies.

Infact the US Federal Reserve is not a government entity - its a private (and public somehow).

This contrasts (as far as I can tell) with Australia, where the central bank is 100% state-owned.
