There are actually three rates in the U.S. that drive virtually everything else, from bond returns to credit card interest rates. Of these, the Federal Reserve actually controls only two (the Federal Funds Rate and the Discount Rate). The third rate, called the Prime Rate, is the rate that most people falsely believe the Fed changes. In truth, this is the one rate the Fed has no direct control over.
As you can see there was a steady rise in interest rates during the 1950s and 1960s. Then in the 1970s, inflation really took hold. The Fed Funds Rate was ratcheted up by Fed Chairman Paul Volcker to try to subdue the threat of hyperinflation and he was successful but only after interest rates hit double digits.
