The USSS is a division of the US Treasury Dept., but they don't "control" the US currency. They were created originally to investigate fraud, counterfeits, and other crimes that would threaten the value of the currency. It's the Fed (our Central Bank, which is really not a part of the Federal government) that controls our currency and interest rates.
