How Do You Lose Money?

CNN's John Sutter says the Fed can disappear as much of their own money as they want. He gives a theoretical example: Wells Fargo makes phony accounts for a million customers. They package them up in securist bonds and sell them to the Fed, he says. The Fed buys them and then they slowly write them off over the QE process,. And that eats, you know, alive the dividends that normally would send a treasury, but then the Fed takes a loss, right?
