I said that interest rates are a function of inflationary expectations, credit risk and supply/demand of lendable capital. The Federal Reserve report I referenced says exactly the same. If a Federal Reserve report does not suffice, I'll add the following: The US government can borrow money at a lower interest rate than any other borrower, because the credit risk is perceived to be lower. Conversely, companies in economic trouble have to pay rates considerably higher than the Microsofts of the world do. And the spread between the rates that good risks and bad risks have to pay varies independently of inflation. You should know that. Case closed.
What event(s) are you suggesting is going to change this favorable situation for the United States, and which economy will replace ours as the safest place in the world to invest?
