The Fed doesn't have the power of setting any useful interest rate, and even the one they do set they seem to follow the market instead of setting it. (What seems to repeat on every country, because the market has more money than the central bank, and the later must avoid bankruptcy.)

Central banks do have the power of controlling the amount of money in circulation on most countries, what does indirectly impact important interest rates. But the US is an exception here, as the Fed decided long ago to let fractional reserves run as low as the banks are deciding the fractions on practice, thus abiding from any control.
