All National Banks in the US are required to provide a certain amount of funds to the Federal Reserve (a small percentage of their own value) and are issued non-tradable stock as compensation for this requirement, since the money the provide is unavailable for regular banking investments. This stock earns a 6% dividend, but any profits
made by the Fed in the course of its operations are paid directly into the US Treasury.

Oddly enough, there are a LOT of people, seemingly, who fight to death the idea that it's otherwise, and others who are quite adept at keeping that information obscured.
